How much does it cost to install a new boiler?

Prices for a new boiler vary greatly because they depend on many factors such as the type, size and brand of the replacement boiler and any additional costs that may result from the installation itself. Typically, a new boiler installation will cost you between £1,500 to £4,000.

However, the old saying “buy cheap, buy twice” also applies to boilers, and there are many reasons why a cheaper boiler may not be the best way forward. For a start, budget boilers have shorter life spans and often only offer warranties of up to 2 years. They also tend to be more expensive to maintain and do not offer the same energy and cost savings as mid or upper-range boilers. So, in the long run, you may be better off with investing a few more pounds into your new boiler.

We always recommend you get a bespoke quote since each home and family has different heating requirements that need be taken fully into account. We nonetheless wanted to give you a guide that will take out all of the guess work for you. Below we’ve put together a table with indicative price ranges that shows the cost of a new boiler installation depending on your current boiler type and the type of boiler you want to change to.

Did you know?

Switching to a more energy-efficient boiler could save you up to £350** per year (or £29 per month) on your energy bills. That means that if you decide to finance your new boiler over a period of 5 years, it could pay for itself because your monthly loan rates would be offset by the cost savings achieved by your new boiler.

We had a problem with our NEST thermostat in that it had failed so we had no heating. Assured Heating responded within 24 hours to replace and install a new Thermostat and make sure all was working as expected. This included setting up the relevant and required APP on our phones. As usual excellent service from all the team, both Amy in the office and the engineer Mark who attended. Many thanks

I have used Assured since I moved in to the area a few years ago. I phoned needing an emergency repair, and within 3 hours of making the call, somebody had attended and the problem fixed. Transparent pricing, polite, tidy and faultless service from start to finish, I wouldn't go anywhere else!

Assured came and completed a powerflush of our heating system. The guy who came was both professional and curtious. He carried out the job efficiently and was very helpful when it came to explaining things. Would recommend this company.

I recently changed my boiler service package changed from HomeServe to Assured Heating Essex. Assured Heating attend my first annual boiler service under the package I have with them. All I can say is what a first class service I received from there engineer Mitch (who deserves a mention for his over all professionalism) I had my previous package with HomeServe for three years, but on my annual HomeServe boiler visit they never picked up a flue fault but Assured Heating did. The fault was, the flue was not sealed correctly on the outside of my property, the Assured Heating engineer Mitch explained the consequences of not having the flue sealed correctly. Mitch then proceeded to correct fault at NO ADDITIONAL COST. Great overall service from start to finish and I would highly recommend Assured Heating Essex..
