British Gas Boiler Installation Costs, Reviews & Comparison

British Gas are probably the UK’s most recognisable name in the energy sector and offer both domestic energy and gas boiler installation.

At present, British Gas install the most boilers compared to any other company, currently installing an estimated 100,000 boilers each and every year across the UK.

Of course, many people choose British Gas entirely due to their recognisable brand and household name, but how do they actually compare to the competition?

Are they the best? Let’s find out how their new boiler installation services compares to other market leaders including BOXT, Homeserve, Heatable & other notable online boiler installers

British Gas New Boiler Costs

Best boilers

If you need your boiler replacing fast, you are probably frantically trying to find out which online boiler installer offers the best price and service.

British Gas are by far the most popular choice, followed closely by Eon, BOXT and Homeserve.

Traditionally, it was the norm to call several local plumbers to get a boiler quote, in which case they would attend your property and carry out a survey and afterwards would provide the itemised quote in full.

British Gas offer a similar service, where a British Gas sales representative will visit your home, carry out a survey and then offer a quote. However, British Gas do also offer an online estimate on their website before you book the survey so you can get an indicative price.

As you can appreciate, this survey process is quite intensive, requiring commitment in terms of time, roughly, these at home surveys can take around an hour, so British Gas have already laid out substantial costs before they’ve even provided a quote.

In addition, British Gas is a huge company with thousands of employees and customer service staff, so this is a huge overhead for them to recoup.

Important note: most other online boiler installation companies e.g. BOXT and Heatable do not require an in person visit and instead rely on photographs and in some cases video footage. The entire fixed price boiler quote is provided entirely over the internet.

A Fair Comparison on Price

Are British Gas the cheapest when it comes to their new boiler installation services?

The reality is that it is quite difficult to do a like for like comparison between different boiler installation companies, since they will typically have slightly different offerings i.e. offer different boiler brands and models, warranties and so on.

However, with that in mind, we have made a comparison between two identical types of gas boiler installation: a standard combi boiler swap, using the Worcester Bosch swapping a combi boiler for a new Worcester Bosch Greenstar 4000 combi boiler, installed in the same location, including a horizontal flue and a smart thermostat.

In this specific example and on the specific date, British Gas charge £2,964 for the boiler installation and include a Hive smart thermostat, as well as a 5 year warranty. 

British Gas also offer boilers on finance, in which case you can pay for your new boiler over 24 months, with 0% available. However, if you opt to order the job on the British Gas Online method, you can make a substantial saving, indicating that they are adding the additional cost of the home survey into the price.

Therefore, if possible, it is better to go the online route if you want to maximise savings, but unfortunately, this service is only currently available for the most straightforward types of boiler installs.

HomeServe offered the same type of install and boiler model for £2,727 which is £237 (-8%) less than British Gas. In terms of finance they also offer the same terms and include a home survey, the major difference between the two brands is the types of smart thermostats offered – British Gas use their own Hive model, while HomeServe use the Netatmo.

BOXT is a newer arrival to the boiler installation company market, but they do offer competitive pricing and extremely long boiler warranties, which makes them even more appealing. For example, for the same type of install, BOXT offer to do it for £2,120, a significant saving of £844 (-29%) versus the British Gas home survey price. BOXT also offer a 10 year warranty, which is significantly longer than both rivals.

Here is a summary of the cost comparison and other key metrics between each brand (accurate on that date and for this specific type of install):

British Gas Install Prices Verdict

In our experience of seeking a quote, if you are buying your boiler from a household name like British Gas you can expect to pay more than other rivals.

If you don’t like the idea of purchasing a boiler without a home survey, then you may want to try HomeServe. However, if you don’t mind carrying out the entire boiler buying process online, then BOXT is a superb option.
