What we fix.
If yours is not on the list, book anyway and say what has happened. The engineer who takes the job sees your answers first.
No heating or no hot water
The fault found at the boiler, the controls or the system, and fixed where it can be on the first visit.
Boiler showing an error code
The code read and the cause traced, from a failed sensor to a blocked condensate pipe.
Low or dropping pressure
Pressure restored and the reason found, whether a relief valve, the expansion vessel or a leak.
Radiators cold or noisy
Stuck valves, trapped air and failed pumps dealt with so the whole house warms up.
Annual boiler service
Book a slot on a day that suits you and keep the warranty and the boiler in good order.
While you wait.
- Reset the boiler once, then leave it
- Note the number on the pressure gauge
- Clear the cupboard so the boiler can be reached
What happens first
The engineer will read the fault code and check the pressure before opening the case.
If it needs more
You get a fixed quote on your phone, built from our price list. Nothing starts until you approve it. Say no and you only pay the visit fee.
How Mains works.
The same on every job. See the five steps.
The price is on the screen first
You see what the visit costs before you give us any details, and your card is only charged when the engineer arrives.
You know who is coming
Name, photo and van registration before they arrive, and a four-digit code at the door that matches the one on your phone.
Checked before they join
We check every engineer’s public liability insurance, and the Gas Safe register before anyone is offered gas work.
Guaranteed for 12 months
If the same fault comes back, tap “The problem has come back” on your receipt and the return visit is free.
People ask.
Are your heating engineers Gas Safe registered?
Yes. Gas work is only offered to engineers whose Gas Safe registration we have checked and that is still in date. You see your engineer’s name and photo before they arrive.
What if the boiler needs a part?
Your engineer sends a fixed quote to your phone from our price list, covering the part and any extra labour. Nothing is fitted until you approve it, and if you say no you only pay the visit fee.
Someone at home is elderly, unwell or very young. Does that change anything?
Tell us when you book. Homes with someone vulnerable and no heat are offered to engineers ahead of other jobs.
Should I try anything before booking?
Reset the boiler once and note the number on the pressure gauge. If it does not come back, leave it alone and book. Repeated resets can make a fault worse.
Midlands first, then city by city.
Mains opens in the Midlands first, then one city at a time, so there is always an engineer close enough to reach you quickly. Put your postcode in and we tell you straight away, or text you the day we reach you.
