Boiler installation procedure

When it comes to having a new boiler installed there are different processes depending on how complex or complicated the boiler replacement process is. For example, there are a lot fewer steps to replacing a like-for-like combination boiler than there are for replacing a combi boiler with a system boiler. There are also more steps if you want your boiler fitted in a different location like the loft or a garage.

How much does moving a boiler cost?

Regardless of how complicated an installation is though, there are 3 broad steps that every boiler installation involves.

Removing the old boiler:

Before a heating engineer can begin fitting your new boiler, they will need to remove the old one. You can make this easier for them by clearing the space around your boiler and ensuring they have easy access to it. If your boiler is installed in the attic, it should be accessible via a set of stairs and a safe walkway, and the room should be lit sufficiently. For a more complicated boiler fitting or the relocation of a boiler, the heating engineer may need to remove old pipework and radiators, before installing the new boiler.

New boiler installation:

Once the old boiler and any old pipework has been removed, the heating engineer will begin the installation of your new boiler and its pipework. Depending on how much work is required and how complex the job is, this part of the process can be extremely quick, especially if you're getting a like-for-like boiler.

New boiler product tour:

Having fitted your new boiler and checked that it has been installed properly, the heating engineer will then provide you with a product tour. This covers how to use the controls, what features the boiler has, and how to set a schedule dictating when the boiler will be on or off. Be sure to take note of your new boiler's features and ask questions while you have the heating engineer present. This will help you to use your new heating system effectively and efficiently, and is a great chance to get answers from an expert.

Following the boiler installation

After your boiler is installed, you should ensure the heating engineer provides you with a Building Regulations Compliance certificate which confirms the unit has been installed safely, and register the installation of your boiler with the manufacturer to validate the warranty. Most manufacturers request that this happens within 30 days of installation.

To keep your warranty valid you will have to get your boiler serviced annually by a Gas Safe registered engineer. This involves them inspecting the boiler inside and out, checking the flue pipe, ensuring that the gas pressure is correct and checking how the boiler performs during operation. Find out more about boiler warranties and boiler servicing.

Boiler installation regulations

When installing a boiler there are many building regulations that need to be followed. These include acceptable locations for the boiler to be situated, where the flue can and can't be located, whether the right size of gas pipe has been installed, and whether the boiler has a high enough efficiency rating. The list goes on.

Frankly, there are so many building regulations to follow when installing a boiler that it's best to let an accredited professional worry about them. So long as you get a Building Regulations Compliance certificate from the heating engineer, you'll know that all of the appropriate regulations have been followed.

The easiest way to ensure that your boiler installation follows all of the required building regulations is by using a Gas Safe registered heating engineer. We recommend getting comparison quotes from at least 3 heating engineers in your area, to ensure you get the best deal possible.

Frequently asked questions:

What is needed for fitting a boiler?

Fitting a boiler is not something you should do for yourself. It can only be done safely and legally by a fully qualified professional, so the first thing you will need is a Gas Safe registered heating engineer (OFTEC for oil boilers). Sometimes this is all you will need to get a boiler fitted, as the heating engineer will often source the appropriate boiler and required components themselves. If you would prefer to source a boiler yourself to cut costs, it is possible to do so, but you will still need to have the boiler installed by a Gas Safe registered heating engineer.
