Step by step boiler installation
Your boiler is at the heart of your home, responsible for everything from making your home cosy in winter, to washing your dishes and running your hot bath after a busy day. Which is why a boiler breakdown can be disruptive and an inconvenience to your daily life.
Choosing the best product and a quality installer for your home is key to making sure you get not only a reliable boiler but also a professional installation.
Finding an installer
We recommend contacting at least three installers to come to your home and talk through your heating and hot water needs, as installers may vary in cost and diagnosis. They will discuss with you whether a simple replacement boiler is appropriate, or if there is a more suitable alternative.
Your installer will also explain the control systems available to you and make a recommendation based on the features you would like and anything extra such as smart functionality, weather compensation or load compensation.
Getting a quote
Your installer will give you a quote after their visit for supplying and fitting the boiler and should include the following work:
- Power flushing the heating system
- Any system changes that may need to be carried out
The overall cost of the boiler and installation will depend on the boiler, system type and location in your home.

On the day
A boiler installation usually takes between 1-3 days to complete depending on the complexity of the job. However, most straightforward like for like swaps can be carried out in the space of a day. The installation process and length of time then varies depending on your requirements. Here are some of the steps your installer may take when fitting your new boiler:
What happens during a boiler installation?
The removal of the current boiler is a typical place installers will start. The length of time this takes again depends on the complexity of the job and the existing system.
According to British Standards, the installer should flush or clean your system. The type of clean may vary depending on the systems condition; a chemical flush may be sufficient or a power flush may be required. It’s important to keep your system water as clean as possible, specifically when having a new boiler installed. A system flush prior to installation will avoid any damage that system debris may cause to your new boiler.
The fitting of your new boiler may require changes or upgrades to your pipework. Pipework may not be a straightforward job, so have the potential to take up a large amount of the installer’s time.
The installer will fit your new boiler either in the location of your old boiler, or in a new location. You can change the location of your boiler, however moving your boiler will take extra time and cost. It is important to listen to the installers recommendations.
Your installer should recommend a system filter is fitted alongside your new boiler inline with British Standards best practice. A system filter is designed to protect your boiler from any debris or sludge that may occur over time; to prevent this the installer will also treat the system with a cleaner first, followed by an inhibitor to prevent corrosion. The system filter ensures your boiler remains efficient and as ‘clean’ as possible, providing the whole house with system comfort. Additionally, other accessories will be fitted such as a control, filling loops, flue and any other accessories you may have purchased
Once your new boiler is fully installed and the relevant pipework completed, your installer will commission the system to ensure everything is working as it should.
Make sure your installer completes a handover with you once the work is finished so you’re as informed as possible, know how to operate the boiler, use the controls and understand some basic maintenance checks that you may have to do during the boiler’s lifetime; such as topping the pressure up in the system and bleeding a radiator.
Either the homeowner or installer will need to register the boiler with the boiler manufacturer so your product’s guarantee is valid, making sure you are covered if you are unfortunate enough to experience any issues.
