Common questions
The things people ask us most
Still not sure? Send an enquiry. We would rather answer a question than have you guess.
-
How often should my boiler be serviced?
Once a year. It keeps it safe, efficient and protects your warranty.
-
How long does a gas safety certificate last?
12 months. Landlords must renew it every year.
-
Do I need a powerflush?
If radiators are cold at the bottom, the system is noisy or the water is dark when bled, a powerflush will likely help.
-
Is a heat pump right for my home?
It depends on insulation, space and your current system. We will visit and give you an honest answer.
-
Do you give free quotes?
Yes. You get a clear, fixed price before any work starts.
-
Do you install oil boilers?
No. Oil is servicing only.
