The amount you spend may change based on the type and size of the central heating system.
This guide covers the different parts of improving your home’s heating system. It also provides information on how much a new central heating system costs in the UK right now.
Understanding Central Heating Installation Costs
The price of installing central heating is not set and can change significantly. The final price depends on many things, like the size of your home, the type of system installed, and how much the engineer charges. It is important to keep in mind that these prices are only figures. The actual cost will depend on the specifics of your work.
What Determines the Costs of a Central Heating System?
The wide range of possible installation costs shows how different every central heating installation job can be. The job will depend on how many rooms your home has and how big it is. From how many boilers you need to how much power your new boiler has and how the pipes are set up.
How does the Price of the Central Heating System Change?
- The size of your home
- The number of rooms you have
- The number of radiators you need
- The boiler output you require
- The pipework distribution
- The installer you choose
You also need to consider the costs of the materials, fittings, and work. The price of installation will depend on which technician you choose. For example, local installers usually charge the lowest rates, while national installers generally charge higher rates.
How Much is the Average Cost to Install Central Heating in the UK?
The central heating system has an average cost between £3,500 and £7,000. This is how it breaks down:
Central Heating Installation Costs
Property size | Number of radiators | Estimated cost |
2-bedroom house/bungalow | 1–2 | £2,000– £2,600 |
3-bedroom house | 2–3 | £4,000–£6,000 |
4-bedroom house | 3–5 | £6,000–£8,000 |
Remember that the price can change based on the type of system installed, its size, and the home’s needs. The boiler is one of the main costs of a central heating system. Boiler, heating controls, and pipe costs are also included.
The difficulty of the fitting process can also significantly affect the cost of the work. Getting a professional evaluation before work is a good way to get a better idea of how much it will cost for your home.
Keep in mind that each home is unique, and costs may vary.

Central Heating Installation Cost for a 3-Bedroom House
Central heating costs for a 3-bedroom house range between £3,000 and £7,000. The boilers, pipes, and labour expenses are also included.
The exact price may change, though, based on several things, such as:
- Type of boiler: Condensing boilers are more efficient but cost more.
- Size of the property: More boilers are needed for bigger homes, which drives up the cost.
- Pipework already there: If your home has no pipes, it will cost more to build new ones.
- Type of fuel: Gas is often used for continuous heating. However, the total cost might change if you use oil or LPG.
The most popular type of home in the UK is a 3-bedroom house. Here are the prices for adding different parts of a central heating system.
Central heating installation Costs 3 Bedroom House
Expense Category | Estimated Cost |
Boiler Upgrade | £1,500 – £3,800 |
New Radiators (2 -3 units) | £300 – £900 |
Additional Pipework | £500 – £1,000 |
Smart Thermostat (Optional) | £100 – £250 |
Installation Labour | £500 – £1,000 |
Total Installation | £2,900 – £6,200 |
Average Central Heating System Component Costs
The average cost of central heating system components in the UK may depend on several factors, including the system type, the home’s size, the number of radiators, and any other parts needed.
Components Costs Overview
Component | Average cost |
Boiler | £610–£3,837 |
Radiator (per unit) | £40–£100 |
Hot water cylinder | £400–£1,300 |
Heating control (thermostat) | £100–£410 |
Pipework (per meter) | £800–£1000 |
Labour | £2,850–£4,200 |
Keep in mind that these digits are only estimates. And the prices of the parts you may need for this job can vary. Talking to a local heating expert is the best way to determine your home’s cost. They give you an idea of how much a full central heating system for your home will cost.
Type of Boiler Replacement
How much it costs to replace your central heating depends on what boiler you need. If you want to change the position or type of your boiler, for example, it will be easy to do a like-for-like boiler swap in the same spot in your home.
A like-for-like swap means that the pipes around the new boiler can easily connect to them. Usually, this work takes one or two days. However, moving to a different type of boiler might take a few days because different types of boilers need other parts to be put in or removed.
Boiler Replacement Costs
Type of Boiler Replacement | Estimated Cost |
Like-for-like combi boiler swap | £1,700-£3,500 |
System boiler replacement with a combi boiler | £1,500-£3,000 |
Conventional boiler replacement with a combi boiler | £2,500-£4,500 |
In the UK, getting a new combi boiler is most common. However, the cost will depend on the type of boiler being replaced.
Gas, Oil, Electricity, LPG, Biomass, Fuel’s Role in Cost
Let’s know what “type of boiler fuel” means. You can fuel your boiler with gas, oil, electricity, LPG, or wood.
On the other hand, gas-fired boilers use natural gas or liquid petroleum gas (LPG) as a solid fuel to heat the home. However, electricity doesn’t burn, so it’s not a fuel. Instead, it’s a heat source. So, we’ll talk about the different kinds of fuels that boilers use to make heat.
Natural gas, which comes from the gas network, is the UK’s most frequently used fuel for boilers. How much gas central heating costs right now depends on how much gas costs. Gas is an easy and familiar way to get energy, but when it burns, it releases carbon dioxide into the air, contributing to climate change and greenhouse gas pollution.
Biomass boilers are better for the environment because they burn organic materials. Robust electric boilers are a simple choice for smaller homes. These devices work without burning fuel and use electricity to heat and hot water.
Electric boilers don’t use fuel to work. So they are environmentally friendly. When used with a green energy grid, central heating systems that run on electricity can also be better for the earth, especially when combined with a home solar PV setup. Talk to a professional engineer to determine how much installing a gas, oil, LPG, wood, or electricity central heating system will cost.
Fuel Type Cost Review
Fuel type | Boiler price | Running cost (per year) |
Gas | £600–£3,500 | £91 |
Oil | £1,000–£4,500 | £500–£600 |
LPG | £1,000–£3,500 | £500–£600 |
Electric | £900–£3,500 | £500–£1,500 |
Biomass | £4,000–£21,000 | £500–£1,500 |
Heating Controls
Heating controls are necessary to improve central heating, save money, and lower carbon pollution.
In the UK, new boilers and radiators are more expensive. Smart controls, on the other hand, save money in the long run, while standard controls cost more upfront.
Here are some estimates of how much different central heating settings will cost, including installation:
Heating Controls Prices
Heating control type | Cost (incl. installation) |
Room thermostat | £100-£170 |
Smart thermostat | £140-£410 |
Radiator valve | £3-£150 |
