A few quick questions, including gas safety. Snap the boiler's display and we read the error code.

Your engineer sees the problem, the boiler and how to get in before they set off.

Checked before their first job, and again at your door. See their price before you book, then watch them arrive.

What they found, in plain English, as they work. Nothing extra is fitted without your yes.

Hot water at the taps, heating on, no leaks. Then you sign it off and pay by card.

Before and after, what was fixed and the gas safety record. Kept with your home.


Every CallOut engineer passes eleven checks before their first job. Then, at every door, their face is checked live and you give them your four-digit code. Only then does anything start.
See the engineer's prices before you book. Anything extra, like a part, waits for your yes. And if your engineer doesn't show, your call-out fee comes back.
