How much does a boiler cost in Highbury?

How much is a new boiler?
Type of boiler Cost excluding installation Cost including installation Average, inc. installation
Combi £500 – £3,000 £1,500 – £4,500 £3,000
System £580 – £3,500 £1,580 – £5,000 £3,290
Conventional £600 – £3,500 £1,100 – £5,000 £3,050
Electric £590 – £2,500 £1,590 – £4,000 £2,795
Biomass £4,000 – £12,000 £6,000 – £21,000 £13,500

The main types of boiler systems are combi (including gas combis and electric combis), system, and conventional boilers. The new boiler cost can vary in terms of efficiency, the parts they use, and the different fuel types they run on. 

Combi boilers are currently the most popular home heating system in Highbury. The most energy efficient boiler models reach efficiency rates of up to 98%, meaning that they will warm up your home without wasting too much fuel in the process. If you’re looking to install a combi boiler, make sure to choose one of the best combi boiler of 2025 options on the market. 

It’s also important to note that the exact cost of getting a new boiler can vary depending on the complexity of the installation and whether you require additional parts. At the same time, any gas boiler installation in Highbury will cost more as it will require a connection to the gas main.

Combi boiler installation in Highbury

When it comes to energy efficiency, combi boilers are the best option. Even though they are compact, they can supply a small household’s taps and radiators without wasting much fuel in the process. However, if your home has more than one bathroom and high heating demands, a combi boiler might not be the right choice. Installing a combi boiler in Highbury can lead to significant savings on your energy bills over time. That said, how much you can save depends on the type of fuel your combi boiler runs on. Currently, gas is the most popular and cheapest option, whereas electricity will cost you more.

System boiler installation in Highbury

For homes in Highbury with high hot water demands, a system boiler installation is a great option. It can supply multiple taps and showers at the same time. System boilers, along with conventional boilers, take up more space than combi boilers. This is due to the need for storage vessels, since they do not provide on-demand hot water. System boilers can be powered by various fuel sources, but the most common choice is natural gas. They can also use LPG (liquefied petroleum gas) or electricity as the energy source.

Conventional boiler installation in Highbury

When it comes to conventional boilers, you should be aware that they require a lot of space. In addition to the boiler unit, a conventional boiler also requires a hot water cylinder and a storage tank to operate. These elements allow it to provide consistent heating and hot water. If you’re looking for a conventional boiler installation in Highbury, you should be prepared for higher installation costs. Fitting a conventional boiler is no simple task. Especially if you’re replacing a combi or system boiler. The pipework in your home will need to be adjusted to accommodate a conventional boiler and the hot water cylinder and storage tank will need to be fitted.

Electric boiler installation in Highbury

Electric boilers use electricity, rather than combustible fuel such as oil or gas, to generate heating and hot water for your home. To operate, they have to be connected to the mains electricity supply, as well as to the mains water supply. Because it hardly wastes electricity when it operates, an electric boiler can help you avoid overspending on your monthly energy bills. That said, electricity prices in Highbury are currently higher than gas. So, make sure to take this into account if you’re choosing an electric boiler for your home.

Biomass boiler installation in Highbury

Biomass boilers run on fuel such as wood chips, logs or pellets. Because of this, they are considered a renewable home heating solution that can help you reduce your home’s carbon emissions. Before moving forward with a biomass boiler installation in Highbury, you should consider how much space you have to house this kind of heating system. Not only will you need enough room for the large boiler unit, but you will also need a sheltered space in which to store the wood it runs on.

How much is a new boiler replacement in Highbury?

The cost of a new boiler replacement ranges anywhere from £1,100 to £5,000. Whether your boiler replacement will be at the lower or higher end of this price range depends on the boiler you choose and the kind of boiler swap you need.

Replacing an old combi boiler with a new one costs around £1,500 - £4,500. Switching a combi with a system boiler is a bit more expensive, costing about £1,580 - £5,000. Finally, replacing a combi with a conventional boiler will cost you somewhere between £1,100 - £5,000. Be sure to keep these estimates in mind when deciding on your new boiler replacement.

However, since the cost of boiler installation depends on numerous factors, you will have to consult multiple Gas Safe registered engineers. This can be a laborious process, taking days of research to find a trustworthy heating engineer with the right price for you. Luckily, we can speed up the process using our service.

What size boiler do I need in Highbury?

Numerous factors can determine the right boiler size for your home:

  • Number of bedrooms
  • Number of radiators
  • Number of bathrooms
  • The insulation in your home
  • Building regulations (if applicable)
The right boiler size for your home
BedroomsRadiatorsBathroomsBoiler size
1-20 to 10118 to 27kW
3-410 to 152 to 328 to 34kW
5 or more15 to 204 or more35 to 43kW

Of course, these numbers apply to the UK in general, so pinning down the exact boiler size for every Highbury household can be difficult. As a rule of thumb, combi boilers are less useful for households with multiple bathrooms, as they produce hot water on demand and this stretches their abilities thin when several taps are operating at the same time.

For higher water flow rates at the expense of a bit of energy efficiency, both system and conventional boilers can do the trick. However, both of these require extra space for additional components like a hot water cylinder and a water storage tank. While they are more adept at providing water for homes with more elaborate needs, they could be less suitable for smaller homes with less space.

If getting a boiler installed seems like an expensive prospect, there are some grants that could cut the costs. The Boiler Upgrade Scheme (BUS), for instance, is taking applicants until 2028 and is geared towards taking inefficient boilers out and upgrading homes for new heating standards. If you have an old, inefficient oil boiler or gas boiler, you may be eligible for up to £5,000 to install a low-carbon heating system such as a biomass boiler.

Boiler replacement vs repair in Highbury?

It’s hard to decide when you should replace your heating system or opt for boiler servicing. Even the strictest regiment of boiler maintenance can’t hold the inevitable at bay. As a general rule, here are a few signs you need to ditch your current heating system:

  • Your boiler was installed over a decade ago.
  • You are noticing higher energy bills resulting from decreased efficiency.
  • Your boiler is making unusual noises.
  • Your boiler often indicates that an error is occurring.
  • You are having difficulty finding replacement parts for your old boiler.
  • You are noticing that your home is becoming more susceptible to the cold.
When these crucial indicators present themselves, it might be a sign you need to get a new boiler installed. Your central heating system will not only cost more to repair, but it may also be messing with your heating bills due to lagging energy efficiency. In such cases, it’s best to opt for a brand new boiler.
