Gas Safety Certificate (CP12) in Merton
From enquiry to certificate: Gas Safety Certificate (CP12) for landlords in Merton, handled by professionals holding the registration the law requires, with pricing confirmed before you commit.
Straight answer
Every rented property in Merton with a gas supply needs an annual landlord gas safety check. Only an engineer on the Gas Safe Register can carry it out, the record lasts 12 months, and renewing in the final two months preserves your existing expiry date.

Letting property in Merton
Letting in Merton: the practical points
The gas rules themselves are national, so nothing about the check is different in Merton — what's local is the housing enforcement around it. London Borough of Merton is the housing authority for the area, and if your property needs an HMO licence, the current gas record is the kind of document its conditions will expect you to hold and produce on request.
The law
Your legal duty, in plain English
The duty comes from the Gas Safety (Installation and Use) Regulations 1998, which apply across Great Britain — Northern Ireland has parallel regulations to the same effect. Breaches are criminal offences prosecuted by the HSE, with fines that can be unlimited and imprisonment available for the worst cases. In England, a missing gas record can also invalidate a Section 21 notice, blocking possession until the paperwork is right.
Landlords must have every gas appliance and flue they provide checked by a Gas Safe registered engineer at least every 12 months, keep the record for two years, give tenants a copy within 28 days of the check, and give new tenants a copy before they move in.
Equivalent annual duty applies in Northern Ireland; engineers must be Gas Safe registered.
Penalties stated are statutory maximums or court-set; London Borough of Merton is the local housing authority for Merton.
Pricing
What a CP12 costs
What moves the price is mostly appliance count: a flat with a single combi boiler sits at the bottom of the range, while a house with a boiler, hob and gas fire takes longer and costs more. Adding a boiler service to the same visit is usually cheaper than a separate appointment. The figures above are national guidance — your confirmed price comes before anything is booked.
Paperwork
Copies, retention and the renewal window
The paperwork rules are as enforceable as the check itself. Give existing tenants their copy within 28 days and new tenants theirs before they move in; keep every record for a minimum of two years; and diarise renewal for the two-month window before expiry — done then, the new record runs from the old expiry date rather than resetting the clock early.
Credentials
Who you're letting in
The credential that matters here is a live Gas Safe registration covering the appliance types in your property — it's what makes the certificate legally worth the paper. We verify it, along with insurance, before a booking is confirmed. No invented review scores on this page; the register is public, and checking it beats any star rating.
The inspection
What the engineer actually checks
A CP12 visit is systematic rather than long: a tightness test on the supply, then every landlord-owned gas appliance tested in turn. The engineer checks that each burns correctly, that safety cut-offs work, that the room has the ventilation the appliance needs, and that flues carry fumes clear of the property. Results, defects and any action taken go on the record, alongside the engineer's Gas Safe registration number — the detail worth verifying.
FAQ
Common questions about the Landlord Gas Safety Record (commonly called a CP12)
Do the same gas rules apply in Scotland, Wales and Northern Ireland?
Yes — the Gas Safety (Installation and Use) Regulations 1998 apply UK-wide (Northern Ireland has parallel regulations to the same effect). The annual check, the 28-day tenant copy rule and Gas Safe registration requirements are consistent across all four nations.
Do I have to give tenants a copy of the gas safety record?
Yes. Existing tenants must receive a copy within 28 days of the check, and new tenants must get one before they move in. For rental periods under 28 days, displaying a copy in the property is acceptable.
Is a gas safety check the same as a boiler service?
No. The safety check confirms appliances are safe to use; a service is a maintenance clean and inspection of the boiler itself. Many landlords in Merton book both together because the engineer is already on site, but only the safety check is a legal requirement.
How long must I keep gas safety records?
Keep each record for at least two years. Because defects and history can matter in disputes, many landlords keep the full chain of records for the life of the tenancy — digital copies are fine.
What happens if I let a property in Merton without a valid gas safety record?
It is a criminal offence under the Gas Safety (Installation and Use) Regulations 1998. Cases are prosecuted by the HSE and can lead to unlimited fines and, in serious cases, imprisonment. A missing record can also block a valid Section 21 notice in England.
My Merton property has no gas supply — do I still need a CP12?
No. If the property has no gas supply or gas appliances, the gas safety regulations do not apply. If the supply is merely capped but a live meter remains, taking professional advice is sensible before assuming you are exempt.
