/ What the gas safety check covers
Under the Gas Safety (Installation and Use) Regulations 1998, landlords must have every gas appliance and flue they provide checked by a Gas Safe registered engineer every 12 months, give tenants a copy of the record within 28 days (or before they move in), and keep records for two years. Councils and letting agents will ask for it, and insurers expect it.
We check every appliance and flue in the property, carry out a tightness test on the pipework and issue the CP12 on the day. If anything fails, we tell you what's wrong and what it will cost to put right, and we can usually do the repair on the same visit so the certificate isn't delayed.
We work with tenants directly to arrange access if you'd like us to, and we'll email you before the certificate expires so you're never caught out at renewal.

/ Gas safety certificate cost in Sutton
The price of a CP12 depends on how many gas appliances are in the property — a flat with a combi boiler and hob is the simplest case. It's a fixed price, quoted when you book, and it's lower when combined with an annual boiler service on the same visit, which is what most landlords do. Any repairs needed to pass are quoted separately.
/ Covering SM1 to SM6 — Sutton town centre and the Times Square tram stop, Wallington, Carshalton, Cheam and Worcester Park
We know the estates around Wallington and Carshalton, the Victorian stock nearer Sutton centre, and the newer flats by the tram network. It's one of the closer parts of our South London coverage to base, so response times here are among our quickest outside Surrey.
We cover the whole of Sutton (SM1 to SM6) — from Sutton town centre and the Times Square tram stop, Wallington, Carshalton, Cheam and Worcester Park — and the surrounding areas including Wallington, Carshalton, Cheam, Worcester Park, Hackbridge, Beddington, Croydon and Epsom. Typical housing here is Victorian terraces near Sutton and Carshalton centres, 1930s semis across Wallington and Cheam, and post-war estates towards Worcester Park, and our engineers know the boiler types, flue positions and system layouts that go with it.
We're based in Woking, Surrey, roughly 45 minutes from Sutton in typical traffic — a normal working day for us, not a special trip.
Same-day appointments are available for most of Sutton, and every job — a service, a repair or a full installation — comes with a fixed price agreed before we start and a written record when we're done.

/ Questions we get asked
Straight answers. If yours isn't here, call — it's quicker than a form.
How often is a landlord gas safety certificate needed?
Every 12 months. You can have the check done up to two months before the expiry date without losing time — the new certificate runs from the old expiry.
What does a CP12 cost?
It depends on the number of appliances. Request a quote and we'll give you a fixed price — and a lower price for combining it with a boiler service on the same visit.
What happens if an appliance fails?
We report the defect on the certificate and quote the repair. If it's immediately dangerous we'll disconnect it and label it, which is what the regulations require; we can usually fix it the same day.
Can you liaise with my tenants?
Yes. Give us the tenant's contact details and we'll arrange access and send you the certificate when it's done.
Do you offer annual reminders?
Yes — we email you before expiry and can book the renewal in advance.
Ready when you are.
