Central heating installation cost for a two-bed bungalow

For a two-bed bungalow, you’d be spending around £5,200 to install gas central heating. A gas boiler will cost around £1,000 - £1,800 for supply and installation. For the radiators, you could expect to spend around £900+ on parts and labour and pipework around £250+ for material and installation. We recommend allowing extra budget for any other costs that could crop up.

For a boiler and installation, you can expect to pay around £1,300 - £2,000. For a house this size, you’d need around ten radiators, which would cost you around £1,500 to install (including parts). You’d also need your pipework, which costs around £1,000 for supply and installation. For the water tank, you should expect to pay around £220. It’s always best to keep extra budget for any extra parts that are needed and any extra work your engineer comes across.

Oil central heating installation costcentral heating installation cost guide

Oil central heating systems are a suitable option for people whose properties aren’t connected to the main gas grid. The fuel is heating oil, used to power the boiler which then heats the water for your radiators and the hot water for your taps.

The benefits of installing oil central heating include:

  • High efficiency of fuel
  • The opportunity to stock up on oil when prices are lower
  • A heating option for homes not connected to mains gas

However, there are also potential drawbacks to consider:

  • Oil prices can fluctuate
  • Modern condensing boilers are much more efficient
  • The fitting of oil heating systems can be expensive
  • A chance of running out of oil if delivery is impossible (i.e. due to bad weather)

Oil fired central heating cost calculator

Taking the average size of property – a three bedroom semi-detached house in the UK – that has 10 radiators of varying sizes, it can cost on average £6,150 to completely install an oil fired central heating system.

This cost includes a new boiler at £2,000, all pipework and radiators at £2,000, and labour at £1,000. If you only need a new oil fired boiler, then the average cost of oil fired central heating installation will be around £3,000.

It goes without saying that each oil fired central heating installation will be different, so it’s wise to get an accurate quote for your property from a professional tradesperson.

Electric central heating installation prices

Electric heating is another option for properties without access to the mains gas network. The most popular system involves night storage heaters, which store electricity obtained at night-time when prices are cheaper. The stored heat is then used to heat the property throughout the day.

Modern storage heaters now come with thermostats and features such as remote wi-fi controls and programmable timers. You can also buy high heat-retention storage heaters, which are designed to be more efficient than previous kinds.

The pros of electric heating systems include:

  • Storage heaters are cheap to install
  • Heaters require little maintenance
  • A heating option for homes without access to mains gas

But like other systems, there are disadvantages to consider too:

  • Electricity can be much more expensive than gas
  • You could face delays and a cold house if your heating hasn’t been switched on

Gas central heating installation cost

This is the most common heating system in the UK. Gas from the mains network is the fuel that powers your condensing boiler, which then heats water for your radiators and hot taps.

There are quite a few advantages of installing a gas central heating system, including:

  • A high level of fuel and boiler efficiency, making it cheaper to run
  • It’s straightforward to replace a boiler if you need to
  • There’s no need to store gas if you’re connected to the main network.

But there are drawbacks too, such as:

  • Expensive to install a full gas heating system from scratch
  • Boilers need regular servicing
  • Gas prices are affected by global market fluctuations
  • Gas is a fossil fuel – so it isn’t the most eco-friendly option

Central heating installation cost calculator

When calculating your central heating installation costs, there are several factors that you need to consider. The most important is the size of the house and the number of rooms. This will affect the size and capacity of the boiler. That, in turn, will affect its price. You will also need to take into account the boiler brand and make, as that will also have an impact on the price.

You will also need more radiators for a larger number of rooms. In fact, you may need more than one radiator in very large rooms. The more radiators you buy and install, the more you would need to pay.

Finally, you will also need to install pipework for heat distribution. You’ll need less pipework for a smaller property.

As a result, you’ll pay less in central heating installation costs for a smaller house.

It’s essential to use a fully qualified, registered central heating engineer, no matter which heating system you choose.
