How much does it cost to install a new boiler in the UK?

Most homeowners can expect to pay between £2,000 and £4,000 in boiler installation costs and then around £90 per month on running costs. Modern units last between 10 and 15 years, though lifetimes for budget units may be shorter than this. 

Swapping out one combi boiler for another tends to be the cheapest option. Total boiler replacement costs are in the £1,400 to £2,000 range for this service. Ongoing combi boiler costs tend to be lowest.

If you’re having a new type of boiler fitted – such as replacing a combi boiler with a system boiler – expect to pay more. Homeowners may need to fork out between £3,000 and £5,000 for an upgrade like this. 

New boiler costs depend on the type of company you use. This British Gas boiler prices is a good financial guide to know what is the best boiler. National firms will often subcontract boiler fitting jobs to local traders in your area (instead of maintaining a network of fully employed staff). Because of the additional overheads of the national operators, prices tend to be higher. When you go local and choose a small firm or sole trader, you can often find engineers offering the same quality of service at a lower price. However, you may not get as many quality guarantees. 

What is involved in the installation?

When it comes to boiler installation costs, there are all sorts of factors that can affect the final price you pay. 

Boiler Unit

As you might expect, the boiler unit itself is often the biggest contributor to the overall cost. 

Budget units start at around £500. From there, costs rise to around £2,500 for a top-of-the-line boiler. The actual price you pay will depend on the complexity of your system. 

Labour 

Labour costs also take up a large chunk of the overall bill. Expect to pay anywhere between £600 and £1,500 for the installation itself. 

Prices vary by location. In the northeast, northwest and Wales, labour costs tend to be lower. In London and the southeast, they are higher. 

Labour costs will also depend on the type of boiler you’re having fitted. Simple combi swaps usually only take a day or so, while full conversions take two days or more. Hence, you’ll pay more for the latter. 

Parts Costs

Engineers will also add parts bills to the cost of new boilers if you require them. Here are some parts and their respective price ranges: 

  • Flue: £300 – £600
  • Plume kit: £90 – £130
  • Main gas pipe upgrade: £250 – £400
  • Heating controls: £100 to £300
  • Magnetic boiler filter: £100 to £200

Warranty

Lastly, you may wish to purchase an extended warranty: cover that will protect you against boiler breakdowns for up to 10 years. Expect to pay anywhere between £10 and £15 per month for this.
