A good boiler typically lasts around 10-15 years, which means most people aren’t familiar with the boiler installation process as it doesn’t happen very often! Knowing what to expect during boiler installation can help ease any worry about what’s going to happen on the installation day.
Before the boiler installation
The first step of the boiler installation process involves a Gas Safe registered engineer carrying out an assessment to understand your boiler requirements. They’ll need to know how many rooms, radiators, and people there are in the house, as well as the position of your current boiler, whether it needs to be moved, or if new pipes need to be installed.
By the end of this appointment, you’ll have chosen which boiler you want and know whether a straight swap is needed, or if there is more work required. You’ll also know how much the work will cost to carry out.
On the day of your boiler installation
The exact process will depend on the nature of your boiler installation. Before any installation, the gas will be shut off and old boiler will be removed. If the installation requires a straightforward swap, the heating system will then be flushed to remove any debris, before the new boiler is attached. The engineer will then test the boiler to make sure it is working properly. These installations usually only take a few hours.
If there is more complicated work needed, such as replacing the pipes or moving the boiler, there will be more work that is carried out, and it can take a few days to complete the installation. The engineer should tell you how long this will take, and what is involved, ahead of starting the work.
Can I leave the house during my boiler installation?
You’ll need to be in the property when the engineers arrive and when they leave, but you do not have to stay in the house during the entire installation process.
