Service & Repairs

Boilers that are over ten years old waste a lot of valuable energy.

No matter what type of boiler your household has, we can quickly diagnose and repair your boiler using quality components and parts. If you are experiencing problems with your boiler and would like to book an appointment for Peter to visit, please contact us today.


Annual boiler servicing is a wise precaution, as we can ensure that your current system is operating to peak performance, ensure against Carbon Monoxide leaks and prolong its lifespan. Regular maintenance can also help prevent a system breakdown which can be expensive and unwelcome.
