The difference between system boilers and combis is that they are suited to bigger homes as they have a hot water cylinder that can store a lot of hot water ready to be used.

This is particularly handy if you have 2 or more bathrooms or showers, or low water pressure. British Gas system boiler prices are around the same as the other types of boilers. Expect installation costs, labour, parts, and materials to be the same too unless you are changing your hot water tank.

If you need a new hot water tank then you will need to purchase this seperately. If you already have a working hot water tank then fitting your new system boiler to use it the same as your old one will all be included in the installation.

British Gas conventional boiler prices including installation

Conventional boilers from British gas are also an option. Also known as heat-only boilers or regular boilers, these boilers are becoming less and less common but they still have their uses for homes that have low water pressure or have high hot water demands.

These regular open vent boilers require both a hot water tank and a cold water tank at a height in a home to work. If you wanted to remove your cold water tank you could change to a system boiler if required. Regular boilers tend to be found in older properties but there are still some manufacturers making these boilers such as Worcester Bosch, Viessmann, Ideal, Vaillant, and more.

British Gas boilers review

As you can see in our British Gas boilers review of their new boiler and installation costs, that British Gas isn’t the cheapest. Yes they do charge more, and they are a reputable company that install thousands of boilers every year across the UK, so they clearly have the trust of the country, but just because you are paying more doesn’t mean you are getting more and vice versa.

British Gas fitting boilers using Local Heroes

If you want to cut your British Gas boiler replacement cost down, you do have the option to buy your
boiler through British Gas but they can arrange a local installer from Local Heroes instead of one of
their own heating engineers. This will save you over £500 and you will get the same boiler
and fitting but at a lower price. This is the same as using other boiler installation companies such as
Boiler Central offers a wider range of boilers and better fixed price quotes. British Gas has clearly seen that
this is a better way of fitting boilers in the UK at lower prices.

Is British Gas the best installation company?

In terms of size and availability, British Gas could be included as the best boiler installers to use. It depends on how you look at it. In terms of price, British Gas is not the best boiler installation company to use as they are far more expensive than most other heating companies. Many people have only heard or big companies like British Gas or Homeserve so they do no know their other options.

The British Gas reviews do not reflect their high prices either as their reviews are not the best on the market either when compare to companies like Boiler Central. If you want to use a large company with a well-trained workforce and pay a higher premium for your boiler then you can choose British Gas. If you want to get the exact same boiler and installation process by equally qualified Gas Safe registered engineers, then use Boiler Central instead and save yourself £100’s.
