Central Heating Cost
How Much Does Central Heating Cost?
The cost of central heating depends on the size of your home, the type of boiler you need and the installer you choose, but if you’re looking for a general starter guide to the costs involved, you’re in the right place.
What does a central heating system cost?
You need to consider the cost of the boiler itself, installation costs and the possibility of other services that will raise the price of a new central heating system.
The cost of a new boiler (without installation or other costs) can range from £450 to £6,000 depending on which brand you choose, the fuel type and whether it is a Combi, System or Regular boiler.
Combi, System or Regular? Combi boilers are usually cheaper to install than System or Regular, as they are compact, all-in-one units, but they generally only suit smaller houses (1-2 beds) and flats. This is because they heat water on demand and struggle to provide hot water to multiple outlets at the same time.
System and Regular boilers are more expensive to install as they require a separate storage tank and possibly a header tank, but this means they keep a constant store of hot water for larger homes with several bathrooms or lots of radiators.
Central Heating Installation costs
Installation prices will vary between installers but can cost anything from £1000 – £8000 depending on how much labour is needed, extra pipework, fuel storage etc.
Natural gas boilers are the most popular in the UK and are usually the cheapest to install as they just need connecting to the existing gas supply. The cheapest type of boiler to install is a Combi, because it’s a single, compact unit with no extra tanks or fuel storage needed. As the installation is simpler the labour costs are reduced. Typical installation for a gas fired Combi boiler costs range from £1,500 to £3,000 for a 1-3 bed property.
LPG (Liquid Petroleum Gas) is a good alternative if your home is not connected to mains natural gas. An LPG boiler installation is typically more expensive than a standard natural gas system due to the need for an LPG storage tank and extra pipework. The installation of a Combi LPG central heating system can typically cost anything from £2,500 – £6,000 depending on the size of property. Ongoing running costs are higher than natural mains gas but lower than standard heating oil.
Heating oil boilers are more expensive to run but they are very efficient at around 92-93%. Typical installation costs are generally higher as the oil storage tank will cost in the region of £800 – £900. You can expect to pay anything from £3,500 – £8,000 for an oil fired Combi boiler installation.
Remember: Where the property size increases so does the cost of installation as any property that has more than a few bedrooms or a couple of bathrooms will require a regular boiler or system boiler with a hot water cylinder. These heating systems obviously cost more due to the greater complexity of pipework and typically range in price from £2,500 – £5,000.
Other Costs to Consider
There may be other costs to consider when replacing your heating system. For example, it’s a very good idea to carry out additional services like a Powerflush or chemical cleaning when changing a heating system which can add costs of between £200 – £500. You may also wish to introduce smart heating controls and / or TRVs.
