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.

Step by step boiler installation

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.

After your installation

Enjoy your cosy home! Once your installer has finished and completed a handover, you can enjoy your heating and hot water as and when you need it. 

In order to maintain the guarantee an annual boiler service is required. A service is a regular check of the boiler’s installation, its performance and safety. We recommend contacting the installer that fitted your boiler to arrange a service. You may want to think about organising this in the summer months to avoid being caught out during the winter.
