Book your Gas Safety Certificate (CP12) in Kensington and Chelsea with a vetted professional — clear pricing guidance, certificates delivered digitally, renewal reminders included.
Straight answer
The CP12 is the annual gas safety record UK law requires for rental homes — Kensington and Chelsea included. A Gas Safe registered engineer inspects every gas appliance and flue, issues the record, and copies go to tenants: within 28 days for current tenants, before occupation for new ones.
Booking
From enquiry to certificate
We're building coverage in Kensington and Chelsea through our national onboarding programme, and we won't pretend otherwise with a fake availability calendar. Send the property details and we'll confirm by email whether we can cover the job, and the price, before anything is committed.
The inspection
What the engineer actually checks
The engineer starts at the meter, checking the gas tightness of the whole installation, then works through each appliance: the boiler, any gas fire or hob you supply, and the flues that serve them. Operating pressure, combustion performance, ventilation and flame supervision are all tested; the flue check confirms combustion products actually leave the building. Anything unsafe is classified on the spot, and the visit ends with the record itself — every appliance listed, every result written down.
The law
Your legal duty, in plain English
The Gas Safety (Installation and Use) Regulations 1998 make the annual check a hard legal duty wherever in the UK you let, Kensington and Chelsea included. The HSE prosecutes failures — penalties are unlimited fines and potentially imprisonment — and in England an expired record blocks a valid Section 21 notice. If the property is a licensed HMO, expect Royal Borough of Kensington and Chelsea to require the current record as a licence condition too.
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; Royal Borough of Kensington and Chelsea is the local housing authority for Kensington and Chelsea.
Renting out in Kensington and Chelsea
Letting in Kensington and Chelsea: the practical points
Letting in Kensington and Chelsea doesn't change the gas safety requirements — the same UK-wide regulations apply from the first tenancy onward. Where geography does matter is licensing and enforcement: Royal Borough of Kensington and Chelsea administers local housing standards and HMO licensing, and a current gas record is standard evidence whenever the council is involved with a rental.
Credentials
Who you're letting in
Gas work is one of the few trades where the register isn't optional: an engineer who isn't Gas Safe registered can't legally sign your record, full stop. We check registration and insurance before confirming any booking, and you can verify any engineer yourself on the public Gas Safe Register — ask to see the ID card, and check the back for the work categories it covers.
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.
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.
FAQ
Before you book: quick answers
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.
How often does a landlord need a gas safety check?
Every 12 months. You can arrange the renewal check any time in the two months before the current record expires and keep the original expiry date — the MOT-style rule — so booking early never shortens your certificate.
How long does a gas safety check take?
Typically around 30 to 60 minutes for a property with a boiler and one or two additional gas appliances. More appliances, or access issues, extend the visit.
What happens if I let a property in Kensington and Chelsea 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.
What if an appliance fails the gas safety check?
The engineer records the defect and classifies how dangerous it is. Immediately dangerous appliances may be disconnected with your permission. You must have faults fixed by a Gas Safe engineer before the appliance is used again; the record itself lists the defects found.
What if my tenant refuses access for the gas check?
You must take all reasonable steps: written requests, offering alternative dates, and keeping evidence of each attempt. You may not force entry. A documented paper trail of reasonable attempts is what the HSE expects if access is ultimately refused.
