Common questions
Do you cover Harrow?
Yes. We cover Harrow and the HA1, HA2, HA3, HA5 postcodes, as part of Harrow. Our office is in Fulham and our engineers work out across Greater London from there.
The top floor is always cold. Will a new boiler fix it?
Only if the boiler is the problem, and in a house with a loft conversion it often is not. More commonly the system was never resized for the extra radiators, or the circuit needs balancing. We would rather establish that first than sell you a boiler that changes nothing.
What does it cost?
You get a price for the work before an engineer starts. If something behind the wall changes the job, we stop and talk to you rather than press on and bill for it afterwards.
