Do you service all makes and models including oil boilers and electric boilers?
Yes — we service and repair all gas boiler makes and models, and carry out oil boiler servicing and installation. For electric boilers or properties considering a switch from a heat pump, we can inspect and advise whether boiler replaced or repaired is the better option. Our gas engineers work safely and efficiently to assess all your heating needs.
Is it worth replacing my boiler rather than repairing it?
If your boiler is over 10–12 years old or requires repeated repair, a new boiler installation is usually more cost-effective.
