    There are several additional costs that you may need to consider when it comes to having central heating installed. Below is a list of the extra expenses that you may want to think about before committing to the job:

    Labour Costs and Timescales

    The average cost to hire a plumber is around £150 to £270 per day. A central heating installation job is considered to be quite a large job and will often require more than one plumber in order to complete the job.

    For a complete new central heating installation, the labour costs will usually fall somewhere between £1000 to £2000 for the full job. Depending on the type of job and the difficulty of the job, it will usually take around 4 to 8 days to complete.

    You will usually receive a quote for the entire job, including the cost of labour for every central heating expert that is involved in the job.

    Those located in London can expect to pay around £200 to £500 more for the total cost of labour for the job compared to those located in the North or other parts of the UK.

    Cost Factors of Installing Central Heating

    There are a number of different things that can affect the overall cost of your central heating installation job. Below is a list of the things that may affect the price you pay for the job:

    Type of Boiler

    You can expect to pay different costs depending on the type of boiler that you’re having installed. For a combi boiler, you will be looking at prices of around £500 to £2000 for the boiler alone. For a system boiler, this could cost £500 to £2500, and for a regular boiler, you would be looking at costs of around £500 to £2750. You can also expect to pay different costs depending on the manufacturer of the boiler.

    Location of Property

    The location of your property can affect the amount you pay for your central heating installation as labour costs in London are considerably more. Those located in London can expect to pay around £200 to £500 more for the total cost of labour for the job compared to those located in the North or other parts of the UK.

    Number of Radiators

    The number of radiators in your system can affect the cost of the installation as you will need to pay for the materials of each of the different radiators, and you will also need to pay for the labour of installing each additional radiator. So, as you can see, the more radiators you get installed in your heating system, the more you can expect to pay for the overall cost of the job.

    Hot Water Cylinder

    A system of regular boiler will usually require a water tank installation. This is where the hot water is stored and heated before being delivered to the hot water outlets. A new hot water tank typically costs between £200 to £500 including the cost of installation.

    What's Involved in Installing Central Heating?

    There are many steps involved in installing a central heating system. The system is very complex and requires knowledge of how to build and put together several different components.

    centralheating2

    Installing central heating can be broken down into six main steps, as found below:

    1. Select the types of radiators and boiler that you would like depending on your preferences and the adequacy of your home.
    2. Find an appropriate place in the home to install the boiler and install it there plus the various components that accompany it.
    3. Fit radiators in all of the rooms in your home. Some larger rooms may require more than one radiator.
    4. Fit pipes around the house and connect these to the valves of the boiler, the radiators, the water tank, and the appropriate outlets.
    5. Ensure all of the radiator valves are closed and that the vents are sealed before then filling the system with water. Bleed each radiator to remove as much air as possible from the system.
    6. Turn the boiler on so that the water heats up. Balance out the flow of hot water to each of the radiators using the valves.

    Although it may not seem like a lot of steps, each of these jobs are actually big tasks that require a lot of work and specific knowledge.

    Can Install Central Heating Myself?

    Although some parts of the job may be easier than others, it is recommended that you hire a professional plumber to fit your central heating system rather than doing it DIY. Particularly if you have a gas boiler as this will need to be fitted and checked over by a contractor who is Gas Safe registered.

    Before having your central heating installed, a qualified installer will usually visit your property for an assessment to see exactly what work is needed. They will then be able to provide you with a quote on how much the job will cost in total, as well as the expected timeframes for completion.

    We highly recommend attaining at least three quotes before choosing the right contractors for the job.

    Building Regulations for Central Heating

    Any work to install a new boiler needs building regulations approval due to the safety issues that are involved, plus the need for energy efficiency. The best way to go about the job is to hire a professional who is certified to carry out the job.

    centralheating3

    The contractor that you hire should have full knowledge of what they need to do in order to comply with the building regulations when it comes to installing your new central heating system.

    Planning Permission for Central Heating

    You do not usually need to worry about planning permission when it comes to installing a new central heating system, considering all of the work that is being completed is internal work.

    If you live in a listed building or a building within a conservation area, you may need to check with your local planning authority before going ahead with the work. A qualified contractor can usually give you the best advice when it comes to the rules and regulations needed to carry out a new central heating system installation.

    Types of Central Heating

    Below you will find an explanation on the different types of boiler and heating systems.

    Combi Boiler Costs

    A combi boiler is a single unit of boiler that generates hot water and heat into the home. A combi boiler does not need a water tank.

    centralheating4

    System

    A system boiler is similar to a combi boiler. It has all of the same components; it just doesn’t heat water. Instead, it works with a steel hot water cylinder. System boilers are a modernised and more efficient alternative to a regular boiler.

    Regular Boiler Costs

    A regular boiler is a heat-only boiler, meaning it only provides heating. It works with a hot water cylinder.

    Types of Fuel for Central Heating

    Below is a list of the different types of fuel that can be used in a boiler. The type that you use will depend on the mechanics of your specific boiler model. Most boilers run off gas or electric.

    Gas Central Heating Costs

    Gas is the most common form of boiler fuel in the UK. It is convenient as it can be transported as both a liquid and a gas.

    Pros

    ✔ Convenient

    ✔ Can be transported as liquid or gas

    ✔ Produces a lot of heat quickly

    Cons

    ✖ Boilers can be bulky

    Oil Central Heating Costs

    Oil is used as a substitute for natural gas. If using oil as a fuel, you must ensure that your boiler has the capability of running on oil.

    centralheating5

    Pros

    ✔ A substitute for gas

    Cons

    ✖ Outdated form of fuel

    ✖ Many boilers are not compatible

    Electric boilers are noiseless and very light compared to other boilers. They also have low maintenance and running costs.

    Pros

    ✔ No noise

    ✔ Very light

    ✔ Low costs

    Cons

    ✖ Sometimes take longer to heat than other models

    Solid Fuel Central Heating Costs

    Solid fuels are often cheapest but are the most polluting form of fuel. They are also being depleted every day, and so renewable energy sources are preferred.

    Pros

    ✔ Low cost

    Cons

    ✖ Not renewable

    ✖ Very polluting

    Benefits of Central Heating

    There are many benefits to installing central heating in your home. Below is a list of these main benefits:

    FAQs

    How do I clean the sludge out of my central heating system?
    You will need to flush your system. Do this by turning your central heating and all of the valves off, open the bleed valve, drain the radiator, and then close the bleed valve. You can also remove the radiator and hose it.
    How does central heating work?
    A central heating system has pipework and radiators connected to a boiler. The boiler provides heat, and the pump moves heated water from the boiler or tank through the pipework through your home and into your radiators. The water then travels back to the boiler for re-heating.
    What temperature should the central heating thermostat be set at?
    Your thermostat should be set at the lowest comfortable heat. This is usually somewhere between 18-21 degrees.
    What is central heating?
    Central heating is the heating of water via a boiler through to the various radiators around your home. It heats your home effectively and efficiently.
    How often should a boiler be serviced?
    A boiler should be serviced once a year.
