boiler installation. from start to finish.

A new boiler is a big purchase, but the installation process shouldn’t be a mystery. We explain what happens, what information matters and what you can expect next when replacing your existing boiler with a new combi.

what happens during a boiler installation?

Before installation

The first step is understanding the property and existing boiler. The information you provide helps establish what is involved and what is best for your home.

Preparation

The installation team prepares the work area and confirms the planned installation. This is where any agreed changes to the existing installation are taken into account.

Remove the old boiler

The existing boiler is taken out as part of the replacement work. The exact process depends on the current installation and what is being replaced.

Installing the new boiler

The new combi is installed in the agreed location, with the necessary connections and installation work completed in line with the requirements of the property.

Commissioning

The boiler and controls are set up and the installation is commissioned. You should receive the relevant documentation and information needed for the new installation.

Aftercare

Your installation should leave you clear on what has been installed, what warranty or guarantee applies, and who to contact if you need help afterwards.

How long does installation take?

A straightforward replacement may be different from a job involving changes to pipework, boiler location or conversion from an existing system. We don’t recommend promising a single installation time for every home. The relevant timing should be confirmed for only you.

Will I need new radiators?

Not necessarily. The need for additional heating work depends on the existing installation and the requirements of the new system. If changes are required, they should be discussed and included in the quotation where applicable.

What if I want to move my boiler?

Tell us during the quote process. Moving a boiler can change the installation requirements and cost, so it is important that the new location is considered rather than assumed.

What about my old boiler?

If removal and disposal are included in your installation, this should be clearly stated in your quotation. Don’t assume that every quote includes every element of removal — check the inclusions before booking.

clear installation. no jargon.

Our aim is to make the process easy to understand before you commit. You’ll know what you’re buying, what the installation is expected to involve and what happens next.

Frequently asked questions

Do I need to be at home?

Any attendance requirements should be confirmed when your installation is arranged, as this can depend on the property and the work involved.

There will normally be a period during installation when the existing heating and hot water cannot be used. The expected interruption should be explained when the installation is arranged.

If a material issue is discovered that changes the work required, it should be explained before additional work is carried out, with the revised cost or next step made clear.
