Many people are investigating new boilers all the time – looking to save money, get more effective heating, and improve the comfort of their homes. But there’s an important question – how much will it cost?
On average a new or replacement boiler will cost anywhere from £1,600 to £4,000. How much you will end up paying will depend on a variety of different factors. What kind of system are you replacing? What are your plans for replacement? This guide will help you to know what you can expect from a new boiler.
Average Costs in 2022
- Back boiler combi conversion – £3,299
- Megaflo unvented boiler – £2,499
- New boiler installation (no existing boiler) – £2,899
- New combi boiler installation – £1,795
- New system boiler installation – £1,999
- System to combi boiler conversion – £2,499
The cost of your boiler will obviously vary a lot – depending on what kind of existing boiler you have, what you’re looking to upgrade to, and if you’re looking to convert.
Combi boilers tend to retail for around £1,500 to £2,750 while new system boilers retail for £1,600 to £2,900. The cost of a ‘regular’ (heat only boiler) can range from £1,800 to £3,200. Prices will depend on,
- Manufacturer (the better the manufacturer, the higher the cost)
- The complexity of the installation
- The model (the better the model, the higher the cost)
The better the boiler and quality of installation, the higher the cost – not to mention the actual complexity of the installation. It can be difficult to give a specific cost for a boiler because of just how much is involved.
What to look for in Replacement Boilers
You should, when it comes to replacement boilers, look for something which suits your home and specific needs. For example, are you looking to save costs? Or are you looking to improve the comfort of your home?
Kinds of Boilers
Conventional/Traditional Boiler
A Conventional, ‘regular’ or ‘traditional’ boiler features a hot water cylinder and cold-water tank. Regular boilers work by heating up the cold water which is then pumped throughout the home.
Conventional boilers don’t use water from the mains.
System Boiler
System boilers are commonly found in older and large homes which have big demands for heating and hot water. System boilers feature a separate cylinder for storing water, which means they can constantly provide hot water – whereas a combi boiler heats water on demand.
System boilers can use three times of fuel; gas, oil, and LPG. This makes them a versatile boiler.
System boilers promise consistent water pressure and a high volume of hot water as well. If you are in a household which demands a large amount of hot water, they are perfect.
Combi Boiler
A combi boiler is probably the most popular style of boiler in the UK. Its casing houses both the water heater as well as the central heating boiler. Water heats up instantly when the hot tap is turned on – meaning there isn’t a need for an external water cylinder. This makes combi boilers excellent for homes which treat space as a premium.
Combi boilers are cost effective and offer superior pressure.
Options – Conversion and Replacement
Replacing a boiler tends to be the cheapest process. For example, replacing a regular boiler will at most cost £2,200.
It is possible to convert existing boilers, rather than replace them.
A system boiler for example can be converted into a combi boiler – which will cost anywhere between £2,300 and £3,000. This is more expensive than having a new boiler installed because of the work that’s required.
Conversion often allows you to free up space while also reducing maintenance costs.
A fresh installation is potentially cheaper, however.
The Costs Involved
The costs involved depend on a variety of factors. This includes,
- Moving the boiler; moving the boiler around the property can demand
- The company you choose – a cost you should never skimp on
- The complexity around the boiler flue – the component that allows gas to escape the boiler
- The location – in some parts of the UK, installations can cost more
- Warranty length
There’s a lot which can decide the final cost of a boiler installation.
This is not to mention labour costs. Most of an installation is labour, and this can significantly.
- Single Day Installation: £250 – £500
- Two Day Installation: £400 – £800
- Three Day Installation: £600 – £1000
Jobs are unlikely to go above three days, but it is not impossible – so be ready to pay additional rates.
