Generally speaking, the price of a new central heating system would be in the range of £3,500 to £8,000. It depends on factors such as various kinds and sizes of boilers, sizes of property, and quantity of installations.
However, you could have it installed for free with the first-time central heating grants in 2025. These government-backed schemes ensure that low-income families can replace their very old inefficient systems with free modern efficient energy systems.
So such people can afford better energy bills and comfort during cold seasons. This installation costs you nothing; it’s all covered, and you pay nothing up front.
If you’ve found yourself thinking, “How much does first time central heating cost in 2025?”, then get ready for a kind of surprise.
Cost of Central Heating System in 2025
The overall starting prices for the central heating installation in 2025 could go up to about £3,500, amounting to £8,000 or slightly higher, which concerns much bigger homes and/or a greater number of radiators. For instance, this has been estimated to be in the region of £4000-£6000 in a three-bedroom house.
This cost depends on a few factors: for example, the type of boiler associated with the size of your house, too, and how much the whole installation work will cost. In addition, other equipment like hot water cylinders and expansion tanks are required, adding up the price.
For example, a small, two-bedroom house can cost £2,500 to £3,500, whereas a bigger four-bedroom house could be anywhere from £7,000 to £10,000.
It is always best to get a written quotation in detail so you know what you are paying for. Labour and installation costs vary too, so always check what is included in your estimate.

What Does a Central Heating Installation Include?
Installing central heating involves several key steps, which affect both the cost and the time required. Here’s what’s typically involved:
- Removing the Old System: The old boiler, radiators, and any antiquated pipework must first be drained and removed.
- Installation of New Components: New boilers, radiators, and pipework are installed and the system is set up.
- Commissioning and Testing: Everything is tested on the system for proper working conditions. And balance will be done for the engineers by the system engineers to achieve perfect efficiency.
You will also need to select the right boiler, and radiator options, which also comprise underfloor heating, as well as all sophisticated heating controls, including, but not limited to, smart thermostats.
Although smart systems are more expensive to install, on the flip side, they compensate for energy efficiency by saving you a lot of long-term energy bills.
What Factors Influence New Heating System Costs?
1. Boiler Type: Combi, System, or Conventional?
This is pretty much all dependent on the type of boiler that you would select to put into use. There is a purpose for every different kind of boiler and therefore each has a different cost:
- Combi Boilers: These are compact and great for homes with limited space. They do not require a hot water cylinder and are ideal for small homes.
- System Boilers: Of course, these require a hot water cylinder also and are better fitted to larger houses with two or more bathrooms.
- Conventional Boilers: They find their application best in larger homes as they have to fulfill a high demand for water.
| Boiler Type | Price Range |
|---|---|
| Combi | £500 to £2,000 |
| System | £600 to 2,500 |
| Conventional | £700 £2,800 |
2. Boiler Size
Size is one of the main factors that would really affect the cost of your boiler’s installation and its efficiency. All boilers are sized according to their power in terms of kilowatts, and the size chosen would, therefore, be decided upon by the needs that you would have at home.
Too small: The boiler would not be able to heat your home efficiently.
Too large: It can be a big energy waste and cost more in the long run.
| Number of Radiators | Combi Boiler (kW) | System Boiler (kW) | Conventional Boiler (kW) |
|---|---|---|---|
| Up to 10 | 24-27 kW | 9-18 kW | 9-18 kW |
| 10-15 | 28-34 kW | 18-26 kW | 18-26 kW |
| 15-20 | 35-42 kW | 27-40 kW | 27-40 kW |
3. Fuel Type: Gas, Oil, LPG, Electricity, or Biomass?
The cost of your heating system will also be greatly determined by the kind of fuel you choose. Following are some of the common kinds:
| Fuel Type | Boiler Cost | 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 |
4. Radiators and Pipework
In all, the price of heating system installation depends on the number of radiators and the extent of the piping job in your home.
The more radiators you have in a house, the more material and labour it involves, thus adding to the overall cost. If your house requires new pipework, or the pipes need replacement, this too can add to the overall cost.
5. Smart Heating Controls
Smart heating controls make it easier to control your central heating, and can potentially save you money on your energy bills in the longer term. They are more expensive to buy than manual controls, though. Here’s a rough idea of how much you might expect to pay:
| Heating controls | Potential cost |
|---|---|
| Room thermostat with dial | £10 – £40 |
| Smart thermostat | £70 – £250 |
| Wireless sensors | £20 – £35 (per sensor) |
| Manual radiator valves | £5 – £35 |
| Thermostatic radiator valves | £5 – £120 (per valve) |
| Smart radiator valves | £50 – £200+ |
6. Boiler Brands
The brand of boiler you select also has an impact on the overall cost. Here is a quick price comparison for common brands:
| Brand | Combi Boiler | System Boiler | Conventional Boiler |
|---|---|---|---|
| Baxi | £610 – £1,300 | £740 – £1,000 | £700 – £1,000 |
| Ideal | £970 – £1,350 | £850 – £1,400 | £750 – £2,700 |
| Vaillant | £900 – £1,800 | £900 – £2,700 | £800 – £1,500 |
| Viessmann | £900 – £3,500 | £1,000 – £1,600 | £850 – £1,200 |
| Worcester Bosch | £730 – £2,500 | £900 – £3,800 | £800 – £2,300 |
7. Labour Costs of Central Heating
Finally, remember the cost of labour. The quotation by local engineers is usually a lot cheaper than those by national installers. However, it is highly recommended to receive a detailed quote with all the materials as well as the labour included in the installation.
Note that the above costs are based on the assumption of an approximate estimate by an engineer at £200 per day, plus the cost of a number of additional workers for an additional £100.
Central Heating New Installations Grants
In total, the UK Government has set aside £12 billion in energy grants to make homes warm and more energy-efficient. The main initiatives include the Help to Heat scheme for those feeling the chill, a finance facility to install central heating, and other measures to save energy. Here’s a look at some of the grants available:
- Boiler Upgrade Scheme
- ECO4 scheme
ECO4 First Time Central Heating Grants 2025
You might be able to get help with the cost if you want to install central heating for the first time. If you qualify, a first time central heating grant would pay for a new installation system of boiler, radiators, and pipework.
How to qualify for the first-time central heating grant?
To qualify for a first-time central heating installment grant, you must generally fit into certain qualifications, for example:
- Living in a property that has never had central heating before.
- Living in a low-income household; or in receipt of benefits related to low income, such as Universal Credit or Child Tax Credit.
- Meeting the specific energy efficiency criteria.
Whether you are exactly eligible may depend on your circumstances, and you may need to check this with the relevant authority or energy provider.
How Long Does It Take to Install Central Heating?
Central heating installation at a 3-bedroom house will take approximately 2 to 5 days depending on the job’s complexity and possible problems that might appear during the work. Of course, it will go quicker if two engineers are installing the system.
Here’s a rough idea of how long different jobs may take:
- Full Central Heating System Installation: A completely new system (boiler, radiators, and pipework) usually takes about 3 to 5 days.
- Boiler Replacement: Replacing an old boiler with a new one is quicker and generally takes 1 to 2 days.
- Installing New Radiators or Replacing Older Ones: The process normally takes a day for each, for a new installation or in cases when there are old replacements. The amount of work and difficulty also include accessibility and what might have to be altered within the pipework.
It is best to get it installed during summer so that your central heating is ready when the cold months start. This could also help keep the costs down.
