## How Much Does Central Heating Installation Cost?

**Most full central heating installations cost £4,250 on average.**

However, installation prices typically range between £3,450 and £5,050, depending on your boiler type, number of radiators, and pipework requirements.

### Central Heating Installation Cost by Property Size

When budgeting for installing a gas central heating system, it's important to establish how many radiators you will require based on the size of your property. As a general rule, when installing gas central heating most experts will recommend having a radiator fitted in every room, as well as it being common practice to have additional radiators in areas such as hallways and landings.

Below we take a look at the estimated costs based on several scenarios, whereby the cost of installing a central heating system largely depends on the number of rooms. However, this may vary depending on the overall size of the property and general labour costs for your area:

| Property Size | Combi Boiler System | System or Regular Boiler |
|---|---|---|
| 1-bed flat or bungalow (4 to 5 radiators) | £2,000–£3,500 | £2,250–£3,750 |
| 2-bed home (6 to 7 radiators) | £2,500–£4,200 | £2,700–£4,400 |
| 3-bed home (8 to 10 radiators) | £3,000–£5,150 | £3,200–£5,400 |
| 4-bed home (11 to 13 radiators) | £3,750–£6,150 | £3,950–£6,400 |
| 5-bed home (14 to 16 radiators) | £4,450–£7,150 | £4,650–£7,400 |

These costs are based on a full system comprising a gas boiler, new radiators, and pipework. Bungalows can sometimes cost less than a house with the same number of radiators, as pipework runs are shorter on a single floor, while flats may cost more if access is restricted or the boiler and flue position is limited.

Larger homes with two or more bathrooms usually benefit from a system or regular boiler rather than a combi, as these can supply hot water to several taps at once.

### Central Heating Installation Cost by Fuel Type

Fuel type is a major cost factor for installing a new central heating system. Gas isn't the only type of [boiler](https://www.myjobquote.co.uk/costs/installing-a-new-boiler), and you could also switch to a heat pump. Here's a look at how other fuel types compare, based on a full new system in a 3-bed home with 9 radiators.

| Type | Installed Cost | Average Annual Running Cost |
|---|---|---|
| Mains gas boiler | £3,450–£5,050 | £720–£960 |
| [LPG boiler](https://www.myjobquote.co.uk/costs/liquefied-petroleum-gas-central-heating) | £2,200–£6,100 | £960–£1,200 |
| [Electric boiler](https://www.myjobquote.co.uk/costs/electric-boiler) | £2,500–£4,500 | £2,900–£3,600 |
| [Oil boiler](https://www.myjobquote.co.uk/costs/cost-of-installing-an-oil-boiler) (including tank) | £6,500–£11,000 | £840–£1,300 |
| [Air source heat pump](https://www.myjobquote.co.uk/costs/air-source-heating-pump) | £9,500–£18,000 | £800–£1,200 |
| [Biomass boiler](https://www.myjobquote.co.uk/costs/biomass-boiler) (wood pellets) | Around £13,000 | £1,150–£1,700 |
| [Ground source heat pump](https://www.myjobquote.co.uk/costs/installing-ground-source-heat-pump) | £16,000–£38,000 | Around £975 |

### Central Heating Installation Cost Breakdown

To help you calculate your central heating installation costs, here's how the individual components of your quote will stack up:

| Job Description | Duration | Average Cost |
|---|---|---|
| New boiler (supply and installation) | 0.5 to 1 day | £1,100–£1,850 |
| Hot water cylinder (supply and installation) | 2 to 3 hours | £180–£250 |
| 9 Radiators (supply and installation) | 1 to 2 days | £1,200–£1,750 |
| Pipework (supply and installation) | 3 to 5 days | £950–£1,200 |
| Total for all above | 4 to 8 days | £3,430–£5,050 |

The supply and installation of the boiler and radiators together make up around 70% of the total cost.

### What Do Central Heating Quotes Include?

Typically, all parts of the job, from supply to labour and installation, will be included in the total price your central heating installer quotes you:

- Boiler supply and install.
- Radiator supply and install.
- Pipework and connections.
- System filling, bleeding, and commissioning.
- Safety checks and certification.

**Here's what's usually not included:**

- Re-plastering and making good/decorating
- Re-fitting flooring
- Electrical upgrades (e.g., new consumer unit)
- Adding smart home features (e.g., installing smart thermostats)

I’m planning ahead for a new boiler in my 4-bed property. What should I expect to budget for this?

"It depends on what kind of system you're going for and how many bathrooms you have. Normally a combi boiler without radiators would be £2,850. If it's a boiler and cylinder, we do it for £3,850. To add 9 radiators on system, that would be a full central heating system, we would add an additional £1,650 for radiators and installation."

## Central Heating Grants

There are a few grants currently available to help cover the cost of installing a new central heating system for the first time, or upgrading an outdated system.

### First-Time Central Heating Grants (ECO4)

This scheme provides grants towards installing central heating in properties that have never had it before, such as those heated by electric storage heaters, gas fires, or other systems.

There are further eligibility criteria, such as your property must have an EPC rating of D or lower, and you must be in receipt of certain benefits or a household income under £31,000.

If eligible, the grant will usually cover the full cost of installing central heating.

### Boiler Upgrade Scheme (BUS)

The [Boiler Upgrade Scheme](https://www.gov.uk/apply-boiler-upgrade-scheme) is available in England and Wales and can help cover some of the cost of replacing a fossil fuel heating system with a heat pump or biomass boiler. Therefore, it's not suitable for central heating powered by a combi boiler, but you may qualify if your central heating system will be powered by an air-to-water heat pump or a biomass boiler.

The scheme currently offers up to £7,500 (or £9,000 for homes heated by oil or LPG), although exact grants vary depending on what heating system you currently have and what you are planning to have installed.

Homeowners in Scotland can access a similar grant via [Home Energy Scotland](https://www.homeenergyscotland.org/home-energy-scotland-grant-loan).

### Warm Homes: Local Grant

The [Warm Homes: Local Grant](https://www.gov.uk/apply-warm-homes-local-grant) scheme is available to those living in privately owned (by you or your landlord) homes in England with an EPC rating of D or lower and with a household income of £36,000 or less.

It's not specifically for installing central heating, but it can fund energy efficiency improvements to your home such as installing smart controls or an air source heat pump.

Availability depends on how much funding your local council has available, so can vary across the country.

## Cost of Installing Central Heating by Region

Central heating installation costs vary across the UK, with heating engineers in London typically charging more than the national average.

Below we compare installation costs in some of the UK's major cities, based on a standard 3-bed semi-detached house with 9–11 radiators, [new combi boiler installation](https://www.myjobquote.co.uk/costs/new-central-heating-cost), new pipework, and heating controls.

| Location | Typical Full System Installation Cost |
|---|---|
| London | £4,500–£7,000+ |
| Birmingham | £4,000–£6,000 |
| Manchester | £3,800–£5,800 |
| Cardiff | £3,700–£5,700 |
| Belfast | £3,500–£5,500 |
| Glasgow | £3,500–£5,500+ |

## Labour Cost of Installing Central Heating

**The average cost to hire a plumber is around £170 to £310 per day.**

A central heating installation job is considered a large undertaking and often requires the services of more than one plumber to complete:

- For a complete new central heating installation, the labour costs will usually fall somewhere between £1,200 and £2,400 for the full job.
- Depending on the type and difficulty of the job, it typically takes 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 who is involved in the job.

It's good to note that those located in London can expect to pay around £250 to £550 more for the total cost of labour for the job compared to those located in the north or other parts of the UK.

## Central Heating Installation Cost by Season

Demand for installing gas central heating is much higher in preparation for the colder months than throughout the rest of the year.

Heating engineers are already often in high demand during this time, as existing systems often require maintenance and if a boiler breaks down then emergency repairs also become a high priority.

Here's what you need to know about how costs vary seasonally:

- **Spring (March to May) —** While a popular time of year for a new heating system and installing gas central heating, prices are often fairly consistent with a steady flow of heating engineers available to carry out the work.
- **Summer (June to August) —** This is the ideal time to hire someone to install your new boiler and radiators as it's generally considered out of season and therefore often companies offer reduced prices. The lack of demand can potentially see you save around 5% to 10% on standard pricing.
- **Autumn (September to October) —** Demand and prices tend to increase in preparation for putting the heating on ahead of the winter months. This can result in costs being around 5% more than usual.
- **Winter (November to February) —** The winter is peak season for heating engineers, and as such, boiler servicing and emergency call-outs dictate the volume of work and waiting lead times. The high demand can then make installations 10% to 20% higher than usual.

The following examples are based on a standard 3-bed semi-detached house (9–11 radiators, new combi boiler, pipework and controls) with average installation costs of £4,500 to £6,000.

| Season | Typical Installation Cost |
|---|---|
| Spring (March to May) | £4,500–£6,000 |
| Summer (June to August) | £4,050–£5,400 |
| Autumn (September to October) | £4,750–£6,300 |
| Winter (November to February) | £4,950–£7,200 |

## Supply Cost of Central Heating Installation

**The total supply cost for a new central heating system typically ranges from around £1,400 to £4,100, based on a 3-bed home with 9 standard radiators.**

Supply costs break down as follows:

| Job Item | Average Cost |
|---|---|
| Combi boiler | £600–£2,300 |
| Electric boiler | £1,700–£2,850 |
| System boiler | £1,150–£2,850 |
| Conventional boiler | £450–£1,750 |
| Panel radiator | £50–£120 |
| Column radiator | £150–£800 |
| Designer radiator | £200–£700+ |
| Cast iron radiator | £200–£700+ |
| Hot water cylinder | £120–£230 |
| Pipework | £350–£700 |

[Radiator prices](https://www.myjobquote.co.uk/costs/remove-and-replace-a-radiator) can vary significantly depending on the size and style you choose. The supply cost of the boiler also varies considerably by fuel type and brand, as well as the boiler's output.

What sort of kilowatt output should a boiler have for a semi-detached house with 5 residents?

"You really need to have a Gas Safe registered engineer call in. The kW output required depends on many things, i.e. what type of boiler you require (combi, heat only, or system), the type of house, number of outside walls, window type and area, type of floor, and total area. Also the number of bathrooms and hot water draw-offs is important to consider."

## Additional Central Heating Installation Costs

Your central heating system may cost more to install than average if any extra work is required, such as:

| Additional Job | Average Cost |
|---|---|
| [Power flushing](https://www.myjobquote.co.uk/costs/power-flush-cost) the system | Around £400 |
| Removing an old heating system | Up to £480 |
| [Moving the boiler](https://www.myjobquote.co.uk/costs/boiler-relocation) to a new position | £500–£1,000 |
| [New gas supply](https://www.myjobquote.co.uk/costs/cost-of-running-gas-to-a-property) to the property | £2,000–£4,000 |
| Hot water cylinder (if switching from a combi) | £230–£575 |
| [Smart thermostat](https://www.myjobquote.co.uk/costs/smart-thermostat-cost) | £140–£370 |
| Smart radiator valves | £30–£80 per radiator |
| [Patch plastering](https://www.myjobquote.co.uk/costs/plastering-an-indoor-wall-cost) and making good | £100–£300 per area |
| [New consumer unit](https://www.myjobquote.co.uk/costs/replace-a-fuse-box) (electric boilers and heat pumps) | £350–£750 |

For a first-time installation in a home with no gas connection, the biggest additional cost is usually getting a gas supply connected. You'll need to arrange this with your local gas network well before installation begins. If you have a back boiler that needs to be removed, expect much higher costs, too.

If you're replacing an existing system, your heating engineer may recommend a power flush to clear sludge from old pipework, especially if you're keeping some of the existing radiators.

Running new pipes often means lifting floorboards and cutting into walls, so you should budget for plastering and redecorating afterwards.

You may need a magnetic system filter fitted to meet your boiler manufacturer's warranty conditions, but this will often be included in your quote.

## What Impacts the Cost of Installing Central Heating?

The main cost factors are the type of fuel and the size of the system, but the cost of installing central heating can also be affected by:

- **Existing Heating System —** A like-for-like swap is usually cheaper than changing the fuel type or a first-time installation that needs extensive pipework fitting. If you need to change the position of existing radiators, [moving radiators](https://www.myjobquote.co.uk/costs/moving-a-radiator) can add to the cost, depending on how far they need to be moved.
- **Boiler Brand & Radiator Type —** Boiler supply prices vary considerably between brands, and there is also a lot of variation in radiator supply costs, from budget-friendly panel radiators to cast iron or designer options.
- **Location of Property —** The location of your property can affect the amount you pay for your central heating installation, as (for example) labour costs in London and the South East are much higher than the national average.
- **Ease of Access —** Allow for as much room on site as possible. Clearing areas alongside walls or laying down protective covers before any tradespeople arrive can reduce the initial preparation work and your installation costs. Parking or the physical layout of your property may make it difficult to get equipment and materials in and out, increasing installation time and labour costs.

## Cost of Alternative Heating Systems

Central heating via radiators isn't the only way to heat your home. Although it's a common choice when upgrading from storage heaters or solid fuel burners, it may not be the best fit for your home. Here's a look at how alternatives compare in terms of both installation and [running costs](https://www.ofgem.gov.uk/your-energy-supply/your-energy-bill/energy-price-cap-and-standing-charges-explained):

| Heating System | Typical Installation Cost | Approx. Annual Running Cost |
|---|---|---|
| Gas central heating (for comparison) | £3,450–£5,050 (9 to 11 radiators) | £65–£105 per radiator (£720–£960 total) |
| [Electric radiators](https://www.myjobquote.co.uk/costs/electric-radiator) | £250–£850 per radiator (£2,250–£7,650 for 9 radiators) | £540 per radiator |
| [Infrared heating](https://www.myjobquote.co.uk/costs/installing-infrared-heating) | £100–£500 per panel (£4,000–£10,000 for a whole house) | £55–£215 per panel |
| [Electric underfloor heating](https://www.myjobquote.co.uk/costs/underfloor-heating) | £40–£90 per m² | £12–£23 per m² |
| Wet underfloor heating | £100–£190 per m² | £5–£10 per m² |
| Storage heaters | £400–£700+ per heater | Around £150–£275 per heater |

Note that underfloor heating is usually priced per square metre rather than by room.

To help you decide which system is best for you, consider the following:

- **Electric Radiators —** Best for properties without a gas supply, as there's no boiler, flue, or pipework to install. They're cheap and quick to fit, but cost several times more to run than gas central heating.
- **Infrared Heating —** Wall or ceiling panels that heat objects and people directly rather than the air, so they are ideal for single rooms. As they also run on electricity, running costs can be high if they are the only heating source.
- **Electric Underfloor Heating —** Often installed in single rooms such as bathrooms, ensuites, or kitchens, ideally during other construction work when the floor is already lifted. Cheaper to install than a wet underfloor heating system, but higher running costs mean it's rarely used to heat a whole home.
- **Wet Underfloor Heating —** This is a different type of central heating, so still needs to be connected to a boiler or heat pump, but frees up wall space and runs at lower temperatures for more efficient heating. Best suited to new builds, extensions, or major renovations due to the disruptive installation process.
- **Storage Heaters —** Common in flats and homes not connected to the gas mains. They charge overnight on cheaper electricity tariffs and release the heat during the day. Although cheap to install and cheaper to run than standard electric radiators (if you have the right tariff), their stored heat can run out by the evening.

What are some good examples of alternative systems to gas central heating?

"There a few. Electric combi boilers, depending on how big the property is. Air source heat pumps and ground source heat pumps, too. Just depends on what your budget is."

## What's Involved in Installing New Central Heating?

Installing a central heating system is a complex procedure and requires knowledge of how to build and put together several different components.

**For this reason, homeowners choose to hire heating engineers to carry out the work safely and efficiently.** MyJobQuote lets you request multiple quotes from [local central heating installers](https://www.myjobquote.co.uk/central-heating-installation) with one quick and easy request.

If you'd like an idea of how central heating is installed, keep reading:

### Before the Job

- **Fuel Type and Boiler Chosen —** Your heating engineer will help you choose the type of boiler and radiators that best suit your energy usage and fuel type.
- **Boiler Position Chosen —** Your heating engineer will then find the best location for the new boiler (usually found in kitchens, utility rooms, or bathrooms).

### During the Job

- **Boiler Installed —** The heating engineer will install your new boiler, be that a like-for-like swap, or a brand new installation.
- **Radiators Fitted —** Once the boiler is fitted, the engineer will move on to fit the radiators, either upgrading existing ones or adding brand new units.
- **Pipework Installed —** New pipework will be run throughout the property, and will be connected to the boiler's valves, the radiators, and the hot water cylinder if your engineer is fitting a system or regular boiler.
- **System Refilled and Bled —** Your engineer will then ensure all the radiator valves are closed and the vents are sealed before filling the system with water. They will then bleed each radiator to remove as much air as possible from the system.
- **Safety Checks —** Your engineer will then check for leaks and make sure the pressure is correct.

### After the Job

- **Boiler Switched On and System Balanced —** Once complete, the engineer will switch on the boiler to heat the water. They'll then go around each radiator in your home and balance out the flow of hot water using the valves.
- **Handover —** You'll then be handed certification or warranty documents, and shown how to use your new system.

**Central heating installation should only be carried out by a qualified professional to ensure safety.**

As we need a new central heating system, should we switch to underfloor heating rather than replace the radiators? What's more cost-effective in your opinion?

"Underfloor heating is more energy efficient due to lower running temperatures, so you will save on energy usage. Radiators are cheaper but take up wall space and generally cost more to run due to higher flow temperatures."

## Building Regulations and Planning Permission for Central Heating Systems

### Building Regulations for Installing 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 approach the job is to hire a professional who is certified to perform the task.

Your heating engineer **must be qualified relative to your fuel type**:

- For **gas boilers**, this means a [Gas Safe registered](https://www.gassaferegister.co.uk/) engineer.
- For **oil boilers**, an OFTEC-registered installer can certify the work themselves, while work completed by a competent installer who is not registered must be notified to Building Control separately.
- For **electric boilers**, an electrician registered with a competent person scheme can certify the electrical work themselves, while work completed by an electrician who is not registered must be notified to Building Control separately.

Depending on the system and the work involved, the installation may need to meet the following requirements:

- **Part L (Energy Efficiency) —** Covers the energy efficiency of every boiler installation, along with the controls fitted to the heating system.
- **Part P (Electrical Safety) —** Covers any electrical work, which can be signed off by the electrician carrying it out if they belong to a suitable competent person scheme.
- **Part J (Combustion and Ventilation) —** Covers combustion safety, including flues, ventilation and carbon monoxide alarms. This does not apply to electric boilers.

The bottom line: The requirements listed above apply in England. Scotland, Wales and Northern Ireland have their own building standards, so check the local requirements with your installer or council if you live elsewhere in the UK.

### Planning Permission for Installing Central Heating

**[You won't typically require planning permission](https://www.planningportal.co.uk/permission/common-projects/boilers-and-heating/planning-permission) when installing a new central heating system if the work is internal.**

However: The following may lead you to require planning permission:

- If your central heating work includes external elements (such as a new flue or external storage tanks), planning permission may be needed.
- If your home is listed, some internal changes may need listed building consent before the work can go ahead. This is separate from planning permission, so check with your local planning authority first.

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.

## Checklist: Hiring a Heating Engineer in the UK

There are a few things you will need to consider before hiring someone to install a new central heating system for you.

Below is a list of some of the main things that you should consider when looking for the right contractor for the job:

- **Do they have the right qualifications?** Depending on your energy type, make sure your engineer has the correct qualifications. For instance, gas boilers must only be installed by Gas Safe registered engineers.
- **Are they suitably registered?** Gas work must be carried out by a Gas Safe registered engineer. For oil, solid fuel or electric heating, check whether the installer belongs to a recognised competent person scheme if they will be certifying the work themselves.
- **Have you been given an itemised list of costs?** Make sure you request an itemised breakdown of costs so you know exactly what's included, and what's not (e.g., waste removal, skip hire, supply of materials).
- **Have you looked at their past projects?** If there are any photos or videos of the trader's work, make sure you look over them to see the quality of work you can expect.
- **What are their reviews like?** Take a look at the engineer's customer reviews on their MyJobQuote profile, and make sure the comments align with what you're looking for.
- **Are they insured?** Check that the trader has public liability insurance to cover themselves and you in the event of any accidents during the project.
- **Do they offer a guarantee or warranty?** Be sure to check if your engineer offers a warranty or guarantee on their work on parts and labour costs.

## FAQs

### How Disruptive Is a Central Heating Installation?

Installing a brand new central heating system in a home can be disruptive. Floors will be pulled up, walls will be knocked through, and more disruption will be seen in properties without existing pipework.

### Does Central Heating Save Money in the Long Run?

Yes, while there's an upfront cost, ongoing savings can be gained from the upgrade in energy efficiency and modern controls, which give you the ability to match your schedule to your energy usage.

### Does Upgrading Central Heating Reduce Emissions?

Modern central heating systems use fuel more efficiently compared to older boilers, resulting in fewer emissions which in turn can also help reduce energy bills.

### Will Central Heating Increase the Value of My Home?

It might not directly impact the price of your home, but it can help to ease any buyers' worries about getting a brand new system installed themselves, which can help with decision-making.

### Can I Install Central Heating Myself?

No, you should only hire a qualified engineer to install your central heating system, rather than attempting to DIY. Attempting to install a gas boiler without any knowledge or training is dangerous and illegal in the UK.

### How Much Does It Cost to Remove a Central Heating System?

Hiring a professional to remove your central heating system will usually cost around £120 to £240 per day, and take 1 to 2 days, so the total cost could be up to £480. If you're installing a replacement system, check if removing the old system is included in your central heating replacement quote before arranging for the work to be done separately.
