  • Cost to Remove and Replace a Radiator

    All you need to know about removing and replacing radiators, including costs of materials and labour, frequently asked questions and tips.

    Average Cost of Removing and Replacing a Radiator

    Depending on the complexity of the job and radiator type, it will usually take around: 2 hours


    How Much Does It Cost to Remove and Replace a Radiator?

    Radiators are an essential item in modern houses to distribute the heat generated from the boiler around your home. Sometimes though, they can stop working and may need to be replaced. Replacing a radiator with a like for like replacement is an easy job for a heating engineer and relatively straightforward for a DIY enthusiast too. However, you may also want to add a thermostatic radiator valve while you are at it. The main thing to remember for an easy replacement is to buy a new radiator that is the same size and has the same pipe fittings as the one you are taking out. You may also want to consider installing an additional radiator to deliver more heat to the room if you find the room is often too cold.

    The prices charged for installing an additional radiator by plumbers will vary according to the amount of pipework required and the complexity of the job. But replacing a radiator is a fairly routine job for plumbers and should be completed in just a couple of hours or so. Another very common reason for removing and replacing a radiator is when decorating. Accessing the wall behind the radiator for tiling, painting or wallpapering is much easier with the radiator removed. Once you have identified that you need to remove a radiator, you need to determine the cost that is going to be involved with the whole job. Prices from smaller local tradesmen range from £150 to £200, but you can expect to pay anything from £175 to £300 to hire someone from a larger company with national coverage.

    Removing and Replacing Radiator Prices

    There are several factors that will affect the total cost of tiling your bathroom. The first is the area that you choose to tile. The most expensive option is to tile the whole room; tiling the floors and the walls top to bottom. The cheapest option is to just tile above the sink. The next consideration is the material that the tiles are made from. There is a big difference between the cost of vinyl tiles and natural stone tiles. The size and shape of the room will have a large impact on the cost of not only materials but also labour. The more the tiles have to be cut, the more difficult and thus, expensive the job. Here are some example costs with some common job types.

    Below is a table highlighting the different costs that may be involved in removing and replacing a radiator and the prices that you should expect to pay.

    Supply Costs Only

    Perhaps you are thinking about installing a new radiator yourself. If that is the case, you may be looking for the prices of radiators alone. There are many different types of radiators, and each one varies in prices. Below is a list of the different types of radiators that you can get and the average cost for each one.

    Central Heating Radiators

    Central heating radiators have the highest heat output and also benefit from having the greatest heating efficiency of any type of plumbed radiator style. This makes them a very popular choice in many homes in the UK. These radiators use corrugated panels to radiate heat out into the room.

    You can get single-panel styles of central heating radiators for small rooms, or you can get double-panel ones for larger rooms as these produce more heat.

    • Small Central Heating Radiator – £20-£40
    • Medium Central Heating Radiator – £40-£80
    • Large Central Heating Radiator - £85-£120

    Column Radiators

    If you are looking to add or retain a little bit of period charm to your home, then a column radiator might be the perfect option for you. These radiators give a nice traditional feel to your home.

    They are very similar in style to cast-iron radiators which originated during the Victorian era. These modern column radiators keep the traditional look but offer much greater heat efficiency than the older models.

    • Small Column Radiator – £115-£190
    • Medium Column Radiator – £140-£230
    • Large Column Radiator - £320-£380

    Designer Radiators

    A designer radiator can bring a wide range of benefits to your home. Some of these benefits include space-saving technologies, amazing designs, and even dual-purpose radiators that double up as mirrors, memo boards, and more!

    These types of radiators are the ideal way to add a contemporary and modern feel to any room. They can create incredibly stylish and attractive features that you won’t need to hide or disguise.

    • Small Designer Radiator – £180-£300
    • Medium Designer Radiator – £200-£450
    • Large Designer Radiator - £350-£500

    Vertical Radiators

    Vertical radiators come in a wide range of styles and colours. They are also very convenient as they can fit perfectly into small wall spaces, meaning you can heat more of your home when you previously wouldn’t have been able to. If you have a small room in your home, a vertical radiator takes up much less space than a traditional one, so it leaves you with a lot more room for furnishings.

    If you choose a bold design, a vertical radiator can even become a part of the décor too.

    • Small Vertical Radiator – £100-£200
    • Medium Vertical Radiator – £150-£250
    • Large Vertical Radiator - £230-£575

    Towel Radiators

    With a towel radiator, you can dry your towels whilst also adding some extra warmth into your bathroom.

    This can look very stylish and is perfect for when you’re getting out of the bath or shower and need that little bit of extra warmth in there.

    • Small Towel Radiator – £25-£150
    • Medium Towel Radiator – £50-£300
    • Large Towel Radiator - £75-£500

    Cast Iron Radiators

    A cast iron radiator takes longer to heat up and cool down than other models of radiator. This means that they keep warm for longer after turning your heating off. With this in mind, these are great radiators for large rooms with high ceilings.

    This model of radiator would be best suited in an older period home; however, they can be a beautiful feature in contemporary décor.

    • Small Cast Iron Radiator – £120-£200
    • Medium Cast Iron Radiator – £250-£595
    • Large Cast Iron Radiator - £490-£750

    Flat Panel Radiators

    If you are looking for a very easy and relatively fast way of changing your radiators, then a flat-panel radiator is the perfect option for you. These radiators are designed to be light and compact. They can fit into almost any room without taking up a hefty amount of space.

    • Small Flat Panel Radiator – £180-£250
    • Medium Flat Panel Radiator – £200-£225
    • Large Flat Panel Radiator - £220-£250

    Stainless Steel Radiators

    Stainless steel radiators are very efficient, but they are also a stunning room feature. They are available in a variety of beautiful finishes that are both easy to maintain, and easy to keep clean.

    Stainless steel doesn’t corrode or rust as some other metals do, and so a stainless steel radiator is guaranteed to last a long time.

    • Small Steel Radiator – £175-£275
    • Medium Steel Radiator – £250-£350
    • Large Steel Radiator - £350-£580

    Mirror Radiators

    Mirror radiators can be a great choice for bedrooms, bathrooms, and hallways. This is because they give the perception of a bigger space. They also double up as a stylish décor item whilst giving off heat to warm the room.

    • Mirror Radiator - £200-£650

    Space Saving Radiators

    A space-saving radiator is a perfect option if you want to make the most of the space in your room. They can fit into narrow spaces, wrap around corners, and can easily blend into the décor.

    • Small Space Saving Radiator – £200-£250
    • Medium Space Saving Radiator – £550-£675
    • Large Space Saving Radiator - £195-£350

    Additional Costs

    Below are some of the additional costs that may become involved with replacing a radiator.

    • New Boiler (supply and installation) - £900-£3500
    • Water Tank (supply and installation) - £150 - £600
    • Pipework (supply and installation) - £800 - £1000
    • Power Flush - £350 - £650

    • Double-Glazing Installation - £2500-£6500

    Labour Costs and Timescales

    Below are the costs you should expect to pay for labour to remove and replace a radiator in the UK.

    Like-For-Like Radiator Installation

    For a simple like-for-like radiator installation, you can expect a professional tradesperson to charge under £500 for the whole job. With the radiator cost included, you will be looking at paying around £200-£300 in the South of the UK, and around £150 in the North of the UK. A radiator replacement should only take a couple of hours. The plumber should bleed and test the radiator system after the installation of the new radiator. It may also be necessary for them to top up the system with water. This depends on how much water you lose in the process of removing the old radiator.

    Additional Radiator Installation

    The price for installing an additional radiator in your home will vary depending on the amount of new pipework that is needed and how accessible the existing pipework is. If you are looking at hiring a small business or sole trader to carry out the work for you, you will be looking at paying around £150-£200. If you would prefer to hire a larger national company, the prices would be around £175-£300.

    Bleeding a Radiator

    Bleeding a radiator is a very simple task. With the right tool, you can bleed all of the radiators in your home in under an hour. However, you can call a professional to do the job for you if you would prefer to have someone else do it. You should not pay any more than £150 for radiator bleedings. Prices usually range from £75-£120.

    Most of the radiator jobs discussed will take a professional a few hours. The timescale with of course vary depending on the amount of radiators. If you are replacing all the radiators inn your home you should expect it to take 1-2 days.

    Cost Factors of Removing and Replacing a Radiator

    There are several factors that may affect the costs involved with removing and replacing a radiator. Below are some of the main things that could affect the price of your job.

    Type of Radiator

    The type of radiator that you are installing may greatly affect the cost of the job at hand. If you are installing a like-for-like radiator, you would be looking at paying a lot less than you would if you are changing the style of radiator installed. Different types of radiators can also vary greatly in price depending on the style that you choose. For example; a medium-sized basic central heating radiator will cost around £40-£80, whereas a medium-sized designer radiator will cost around £200-£650.

    Size of Radiator

    Radiators come in a variety of sizes, and this will affect the cost. Depending on the size of the radiator, it may take a plumber longer to install the radiator. This will also affect the cost as the plumber will charge more for a bigger job. For example; a small basic radiator will cost around £20-£40 whereas a large basic radiator will cost around £85-£120.

    Number of Radiators

    If you need more than one radiator removing and replacing, then you will need to factor in the extra costs of the additional radiators, plus the additional costs involved with the labour. It will take a lot longer for the tradesperson to install more than one radiator, and the cost will increase depending on the length of time that the entire job takes. For example; replacing one radiator will cost around £200, but replacing all of the radiators in your home will cost upwards of £1,000.

    New Pipework

    If the plumber has to install new pipework into the system to fit your new radiator, this is also going to incur some additional costs. You will need to think about the price of the additional pipework, as well as the extra cost of labour for fitting the new pipework. Pipework supply and installation will add around £800-£1,000 to the total price of the job.

    Reasons to Remove and Replace a Radiator

    There are several reasons why you may want to remove and replace a radiator in your home. Some of the main reasons why you may need to change a radiator are listed below.

    Age – Generally, it is recommended that radiators should be replaced every 15-20 years. If your radiators are getting close to this age range, it’s worth taking a look at them and evaluating how they are performing.

    Rust – Rust can often occur on the outside of radiators due to their heating and cooling nature. If rust isn’t treated right away, it can become a problem and can eventually cause leaking.

    Corrosion – Corrosion can occur within your radiator due to sludge which can build up over time. This causes rusting from the inside of your radiator and can eventually lead to leaks.

    Blockages – Blockages can be caused by a clog of sludge or rust. This can prevent the radiator from heating up.

    Lack of efficiency – A less efficient radiator leads to heat loss which can result in it taking a lot longer to heat the room.

    Upgrade – You may wish to upgrade your current radiators for new models.

    Leakages – Leakages can occur for a number of reasons and can often be difficult to fix.

    Things to Consider When Installing a Radiator

    When replacing a radiator, you should think about the boiler capacity and efficiency. If the boiler is more than 10 years old, it will probably be worth replacing the boiler too. Replacing your boiler is an expensive investment and you may need some help choosing the right boiler, with so many options out there, all with there own benefits and drawbacks.

    Another related job is fitting TRV valves for more efficient control of room/radiator temperature. Thermostatic Radiator Valves (TRV) control the temperature of the radiator by sensing the room air temperature and automatically opening and closing the water flow to the radiator to maintain a pre-set temperature. TRV’s are now a requirement as part of building regulations in homes, but many older properties still do not have them. Check with your installer to make sure you have the correct valves.

    Additionally, there is no point in having efficient radiators if your house is poorly insulated. Insulate the loft to at least 150mm of modern insulation and look into double glazing if you do not have it already fitted.

    Finally, you need to consider if you really do need a new radiator of if there is an issue with your system. It may be worth getting a power flush through your central heating to remove all the sludge and debris that builds up over time.

    DIY Radiator Replacement & Removal

    It is always recommended to seek professional advice or hire a tradesperson to carry out the job of removing and replacing a radiator if you are unsure of how to do so or if you aren’t confident in your plumbing skills.

    Below is a guide on how to remove and replace a radiator.

    Tools and Materials Needed

    • New radiator
    • New radiator brackets
    • Washing up bowl
    • Two adjustable spanners
    • Radiator bleed key
    • Drill
    • Pipe/Cable/Stud detector
    • Cloths or rags
    • PTFE (thread seal) tape
    • Steel wool

    Removing and Replacing Your Radiator

    The best way to remove and replace a radiator yourself is to choose a replacement that has identical pipe centres. These are the distance between the two water pipes. This will make the job a whole lot easier.

    If you choose a radiator that is a different shape or size, then you will need to drain the system and make some alterations to the pipework.

    Step One

    The first step you need to take when removing and replacing a radiator is to shut off the valves at either end.

    Turn the manual valve clockwise until it doesn’t turn anymore.

    If your valve is a TRV, turn it until it is in the off position.

    If you have a lockshield valve on one end, you simply need to pull the plastic shield off and then turn the shaft clockwise with a spanner. Be sure to count the number of times you turn the spanner as this will ensure that you can set your radiator to the same flow rate.

    Step Two

    Place a washing up bowl underneath the valve so that the water can be caught as it begins to drain.

    Loosen one of the cap nuts that connects your valve to the radiator using your adjustable spanner. You may need to use the second spanner to secure the valve body to prevent it from turning and ruining the pipework.

    Step Three

    Locate the bleed valve at the top of your radiator and open it. Then, loosen the connecting cap nut between the radiator and the valve to drain the water away. Make sure to catch the draining water in the washing up bowl.

    If your radiator is quite old, the water inside may be quite dirty or sludgy. Keep this in mind as you may need to wipe up any spillages using your cloth or rags.

    If your washing up bowl isn’t deep enough to collect all of the water, just tighten up the connecting cap nut again, pour the water away, and then re-start the process until it is fully drained. When there is no more water coming out, disconnect the valve located on the opposite side of the radiator.

    Step Four

    If your radiator is a large one, you may need someone to help you do this step.

    Lift your radiator away from the wall mounting brackets and then tip it to drain any remaining water out. Once all the water has stopped exiting, stuff the outlets with some rags or tissue to stop them from leaking.

    If the brackets that are currently on your wall don’t suit your new radiator, remove them. You will then need to replace them with appropriate ones.

    If you have to drill into the wall to do this, always be sure to check what is behind the wall. You don’t want to accidentally drill into a pipe. A digital detector will help you determine what is behind the wall.

    Step Five

    Carefully remove the valve connectors from your old radiator using a spanner.

    Using wire wool, clean the connectors and then wind your thread seal tape between five and ten times around the threads to ensure that a watertight seal is created.

    Screw these connectors into your new radiator and be sure to tighten them completely. Then, hang your new radiator on the wall.

    Connect the valves to the new radiator once it’s on the wall and reset them. Don’t forget to check the number of turns you did earlier so that it’s on the same settings as the previous radiator. Once this is complete, allow water to enter the radiator.

    As this is happening, you will need to open the bleed valve slightly to allow any air to escape. When the water begins to spurt out, close the bleed valve.

    Check each of the valves for leaks and then tighten and dry them if needed. Turn your central heating on and keep checking back every now and again for any drips.

    How To Bleed a Radiator

    Bleeding your radiators is quite a simple job if you know what you are doing. Below are ten simple tips on how to bleed a radiator successfully.

    • Turn your central heating on and make sure that your radiators are fully turned up. Wait until your radiators are hot before you move onto step two.
    • Feel all of the radiators in your home for cold spots. This will allow you to identify which radiators need bleeding. If you need to bleed more than one radiator, start with the ones on the ground floor and begin with the one further from the boiler before moving on to the upper floors.
    • You will need to turn your heating off before bleeding your radiators. Keep the intake valves open but turn the heating off. If you leave your heating on, the water pumps may actually suck more air in.
    • Wait for your radiators to cool down and don’t attempt to bleed them until they are fully cool. If you don’t wait until your radiator is cool, you may end up having boiling water spurting out. It’s also good to let the contents of the radiator settle completely to make the bleeding fully effective.
    • Collect your supplies. You will need old towels, a container, a cloth, and a radiator key. Bleed valve keys are usually supplied with your radiator. If you can’t find the one that came with the radiator, you can pick one up at any DIY shop. Sometimes the water that comes out of older radiators can be quite dirty, so it is essential to put down some old towels, especially if you have light-coloured carpets.
    • Locate the bleed valve. You will find the bleed valve at the top of the radiator on one end. It looks like a round hole with a square in the middle. Place your old towels underneath the bleed hole and also place the container there to catch any spillages.
    • Attach the radiator key to the square in the middle of the bleed valve. Turn the key anti-clockwise. If you need to get a better grip, use a cloth. This is also helpful for catching any drips that may come out as you’re turning the key. Do not open the valve fully or water will come pouring out after the air has been released. You will hear a hissing sound as the air starts releasing.
    • Wait for the hissing sound to stop. When all the air has been released, water will begin to trickle out. Wait for a steady stream of water to begin coming out instead of just spits. This is an indication that all of the air has been released.
    • Re-tighten the valve using the radiator key and then use a towel to wipe up and water that may have spilt onto the radiator. If you need to bleed multiple radiators, this is the point where you will move onto the next radiator and complete the above steps.
    • Once you have bled all of the necessary radiators in your home, turn your heating back on to check if the bleeding has been successful. Feel over all of your radiators to make sure they are warm all over and double-check to make sure there are no leaks.

    Cost of Moving Your Current Radiator

    Most of the time, your house will be built with radiators in the middle of the wall so that the heat distributes evenly around the room. However, this isn’t always ideal, and so you may want to move your radiator to a different part of the wall, or to a different wall completely.

    Moving a radiator will usually take around 2-3 hours and the cost to move a radiator professionally is around £200.

    It is best to leave moving a radiator to a professional as there are many things to consider when moving a radiator such as what is behind the wall and how to move the pipework. It’s not a simple job, especially if you don’t have great plumbing skills.

    Radiator Maintenance and Repair

    It is important to ensure that your heating is working efficiently, not just for your comfort, but also for your bank balance. During the colder months of the year, you will need to heat your entire property quickly, and you will want it to stay warm. Knowing how to fix some minor issues and maintain your radiators will help you keep your home warm without having to call out a professional.

    You will need a qualified professional to install your central heating system, but maintaining your radiators isn’t too difficult.

    If you feel cold spots on your radiators, or if they are taking a long time to warm up, the first thing you should try to do is bleed your radiators. This will usually fix any cold spots and will help make your radiators work more efficiently.

    If bleeding your radiators doesn’t fix the cold spots, it may be an indication of a deeper issue, and you will need to call a professional out to have a look at it.

    How to Fix a Noisy Central Heating System

    Every boiler has different controls, so be sure to keep your manual in a safe place so that you can always refer back to it. Most central heating faults have quite simple solutions that you can usually fix yourself. If you are in doubt, however, always call in a professional.

    How to Fix Creaking Pipes

    Creaking pipes can be caused by the hot pipes expanding, or by the pipes rubbing up against the wall, floor, or other pipes.

    To fix this issue, try widening the pipe notches in the joists. If you have loose pipes, clip them or pack insulation between the pipes.

    How to Fix Humming Sounds in Pipes

    Humming sounds can occur in pipes when the pump speed is too high, or when your pipes are too narrow for the system flow.

    How to Fix Rushing Sounds in Pipes

    Rushing sounds in pipes are usually caused by air or bubbles within the system.

    The best way to fix this issue is the bleed your radiators. If bleeding the radiators doesn’t fix this issue, then it is best to call out an engineer to check for a deeper issue.

    How to Fix Hissing or Banging Sounds

    Hissing or banging sounds can be caused by a faulty boiler or thermostat, or a build-up of limescale in the system.

    It is best to call out an engineer to check your system over. They will be able to best determine the issue and will be able to fix it effectively.

    If your central heating system is making noises, it is best to treat the issue earlier rather than later as leaving it could lead to further issues down the line.

    If you're having repairs or maintenance done this is an ideal time for upgrades. It may be worth upgrading your boiler, radiator or installing a new smart thermostat.

    DIY Vs Hiring

    Although replacing a radiator can be done as a DIY job, there are many advantages to choosing a professional to carry out the job for you, including:

    They have the right experience

    A professional plumber will have all the right skills and will be trained correctly on the best practices of the job. They will also usually have many years of experience.

    It takes the pressure off you

    If you hire a professional to do the job for you, they will handle everything so you won’t need to worry about a thing.

    They will have the right materials and tools needed

    A professional plumber will have all of the correct tools needed to ensure that the job is carried out correctly and efficiently. This saves you from having to find the tools yourself.

    They are familiar with plumbing codes

    By finding a plumber that is familiar with plumbing and building codes, you can ensure that your new radiator installations comply fully with the law.

    Professionals are more efficient

    A professional plumber will have a plan already in place for the job and will have all of the right tools ready. Often, choosing the DIY route will end up costing you more money and time than you originally anticipated.

    Professional plumbers are excellent problem solvers

    One of the biggest pros of hiring a professional is that they can easily identify any issues with your system and they will know exactly how to fix these issues and will also ensure that the same thing doesn’t happen again in the future.

    Although hiring a professional does cost money, you may find that you save a lot of time, effort, and even additional costs by going down the professional route. Doing the job yourself and saving money may seem appealing, but it could leave you with a lot more problems than anticipated, especially if you are not confident in your plumbing skills. That is why it is always recommended that you choose to hire a professional for this kind of work.

    Hiring a Radiator Expert Checklist

    Below is a list of things that you should consider before hiring a professional to fix and problems with your radiator.

    • Is the tradesperson Gas Safe registered?
    • Can they offer a warranty on their work?
    • How many years of experience do they have fixing radiators?
    • Are there any extra fees involved?


    Below are the answers to some frequently asked questions about replacing and repairing a radiator.

    What’s A Corrosion Inhibitor And Do I Need One?
    A corrosion inhibitor is a chemical that is added to central heating systems to prevent black sludge from forming in the radiators, pipework, and in the boiler. If you are worried about corrosion, it may be worth thinking about adding a corrosion inhibitor to your heating system.
    Do I Need Thermostatic Radiator Control Valves On My Radiator?
    You don't need them, but they are highly recommended as they allow you to set the temperature required for each particular room, allowing better control of the heating system and saving you money on heating bills.
    Where Should I Position My Radiators?
    In modern homes, the position of radiators is not that important; however, in older homes, you should put radiators in the coldest part of the room, which is normally under a window. Ideally, you should have one radiator for every four metres in a room.
    Do Cast Iron Radiators Take Longer To Warm Up Than Standard Radiators?
    Yes, they do, but they also stay warm for longer after the central heating has been turned off. Cast iron radiators are becoming more popular amongst heating engineers and architects as they tend to warm the fabric of the building more which helps to reduce damp and condensation.
    Why Is My Radiator Hot At The Top And Cold At The Bottom?
    This usually means that the radiator is receiving an insufficient flow of water. This is often due to a blockage or pockets of oxygen in the system that needs venting. If you know how to bleed the radiators, you can try this yourself to clear any air. Otherwise, you should contact a heating engineer to investigate further.
