Before you book
Can you get to me in Harrow?
We do. Harrow is part of Harrow, and we come out to HA1, HA2, HA3, HA5. Our engineers set off from the Fulham office and work all over Greater London.
Our upstairs never warms up. Is it time for a new boiler?
Maybe not. In a house with a loft conversion, the cause is usually elsewhere. The extra radiators may be more than the system was built for, or the heat may need sharing out more evenly. We’ll check that before quoting, so you don’t pay for a boiler that leaves the top floor just as chilly.
How much will it be?
We tell you the price before we start. Sometimes we open things up and find more than expected. If that happens, we stop and talk it through with you. No surprise extras on the bill.
