Frequently Asked Question

What’s the average cost to install a new boiler?

The average cost of a new boiler installation in the UK  is around £1,000-£1,500+. However, cost can vary significantly depending on the size and the type of boiler (gas or electric) needed. Do you need a combi boiler, a system boiler or a conventional boiler and what Kw rating is needed for the property and family size? All of which dictates the boiler size and price?

Can an electrician install a gas boiler?

Although an electrician will be required to do the final wiring for an electric boiler, only a gas-safe engineer is authorised to install a gas boiler. However, an electrician can install an electric boiler. A gas engineer can also install an electric boiler providing them the electrical qualifications i.e., Part P. 

All serviceteam gas engineers have electrical qualifications, so only one tradesperson is needed to install a gas or electric boiler, you won’t need two tradespeople (and pay two charges).

Could a keen DIYer legally install a boiler?

Definitely NOT! it’s illegal for a boiler to be installed by someone who is not a gas safe registered! It’s all about safety, should an accident happen through faulty workmanship by a non-qualified person resulting in serious injury or loss of life would mean a huge fine and or imprisonment or both! 

Be warned! 

Always check an engineer’s Gas Safe registration from their ID, which usually has a picture of the engineer and their Gas Safe number – a quick call to Gas Safe on 0800 408 5500 will verify (or not) the engineer’s registration details.

How long does it take to install a replacement boiler?

Usually boiler installation may take 1 – 2 days depending on the complexities i.e., boiler needs to be sited in a new location, it must be concealed, new radiators needed etc.or any hidden problems. In any of these scenarios the boiler installation could take a max of 2 days. However, during the works the engineer will inform you of any unforeseen situations and ensure the heating and hot water is returned without any delays.

Do I need new radiators when my boiler is replaced?

It depends on the condition of the radiators. If they are old and a power flush has never been carried out then definitely yes - or you could have a power flush before the new boiler is commissioned? A new boiler and new radiators is a great combination as it ensures no debris or sludge is circulated through the system and into the new boiler causing a problem or a breakdown!
