Gas boilers

Potterton boilers are manufactured in the UK, using tried and tested technology and genuine, approved components. Every boiler is tested using gas, electricity and water before it leaves the production line. If it doesn't get 100%, it doesn't pass.

We have a boiler to suit every home, from the smallest flat to a luxury house, and everything in between. All Potterton boilers comply with Energy-related Products (ErP) Directive and are backed by our team of experts:
