new boiler installation

So, you’€™ve come to the decision to opt for a new boiler installation – but what should you look for in a new boiler? As well as saving you a good chunk of money on your household bills, a new boiler heats up your home quickly and efficiently. There are a few things to look out for when choosing a new boiler – check out our helpful guide:

Rules and regulations

There are a few regulations you need to ensure you adhere to before your new boiler installation. You’€™ll need to make sure the condensing boiler is at least 88% energy efficient or A-rated according to the  Seasonal Efficiency of Domestic Boilers in the UK (SEDBUK) scale. Range cooker boilers should be at least 75% energy efficient, whereas non-condensing boilers should be at least 78 – 80% energy efficient. However, it is now a legal requirement that all new boilers are condensing. In some rare occurrences, you may need to fit a non-condensing boiler but you will need a certificate from us as proof.

Planning permission

If you live in a listed building then you made need planning permission for your new boiler. This is also the case if you need a new chimney for the boiler, as it counts as building work.

Landlord permission

If you’re renting then it’€™s best to let the landlord know you need a new boiler. They will usually arrange this for you, so it shouldn’€™t cost you anything. Installing a new boiler without the landlord’s permission could lead to disputes.


Taking into consideration your lifestyle and house type is a big factor in deciding which boiler to install. Smaller houses would benefit from a combi boiler as they take up much less space. They’re also great for bigger families as they’€™re more energy efficient.

To combi or not to combi?

A combi boiler means the hot water cylinder is included in the boiler, as opposed to a separate unit with a system boiler. Again, if you live in a smaller home, a combi boiler is definitely the best choice for you.

Thermostat for maximum control 

Last, but definitely not least, it’€™s a good idea to ensure you get a thermostat fitted. Not only does this give you optimum temperature control, it can save you money on your energy bills. Building regulations require you to install a high quality thermostat – which the engineers can do for you!
