Landlord Gas Certificates
If you let a property you must have every gas appliance checked every twelve months and give the tenant a copy of the record. That is regulation 36 of the Gas Safety (Installation and Use) Regulations 1998, and the penalty for missing it is not a small one.
We hold the dates for you. You get a reminder before the certificate expires, not after.

Emergency call out · Kelder Bridge
Boiler died on the coldest night of the year. Someone answered at 11pm, an engineer was here by half past midnight, and the price he quoted was the price on the invoice.

Rental certificates · Foundry Quarter
I have six rentals and Mainsford holds every inspection date. I have not had to think about a safety certificate in four years, which is exactly what I am paying for.

Boiler service · Orchard Park
Two firms told me I needed a new boiler. Mainsford found a stuck valve and told me the boiler had years left. That is why they get the bathroom job.

Emergency line, open now
0800 612 9871
An engineer on the road inside 90 minutes. Fixed $149, day or night.
First: turn the stopcock clockwise until it stops, then open the cold taps to drain the run.
First: check the boiler pressure gauge. Under 1 bar, leave it off and tell us the reading.
First: note the fault code on the display. Reset it once only, never repeatedly.
First: switch off the electrics for that floor at the consumer unit, then the stopcock.
First: stop using every tap and flush on that stack, so it cannot back up further.
Not us: leave the house and ring the National Gas Emergency line on 0800 111 999.

Heating · 12 August 2026
Five minutes with a key fixes a cold top. If the bottom is cold too, the problem is somewhere else entirely.

Twelve months, every appliance, and 28 days to give the tenant a copy. The duty explained without the legal wording.
