Gas Safety Certificate (CP12) in Hounslow
Arrange a Gas Safety Certificate (CP12) for your Hounslow rental without the ring-around: we confirm price and availability, the certificate arrives digitally, and the renewal date is tracked for you.
Straight answer
Every rented property in Hounslow 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.
Booking
How it works
Our network doesn't yet show confirmed availability in Hounslow. Rather than guess, tell us what the property needs and we'll come back with a real answer — coverage, timing and price — before you decide anything.
The inspection
What the engineer actually checks
Expect the visit to run appliance by appliance. Tightness testing at the meter comes first, ruling out leaks anywhere in the pipework. Each appliance is then fired up and tested — burner pressure or heat input, safety devices, stability, ventilation to the room — and each flue is checked for pull and termination. Defects are graded by how dangerous they are, and only a Gas Safe registered engineer's signature makes the resulting record valid.
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 Hounslow is the local housing authority for Hounslow.
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.
For landlords in Hounslow
Letting in Hounslow: the practical points
For landlords in Hounslow, the practical points are the universal ones: annual check, Gas Safe engineer, tenant copies on time. Keep the record where you can produce it quickly — for your agent, your insurer, or London Borough of Hounslow if the property is licensed or ever inspected. Certificates that can't be found cause almost as much trouble as certificates that were never done.
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
Anyone can print an invoice; only a Gas Safe registered engineer can issue a valid landlord gas safety record. That registration — and insurance to back the work — is our non-negotiable bar for professionals we book. The Gas Safe Register is publicly searchable, so you never have to take anyone's word for it, including ours.
FAQ
What Hounslow landlords ask us
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.
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.
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.
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.
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.
Who can carry out a gas safety check in Hounslow?
Only an engineer on the Gas Safe Register may legally carry out landlord gas safety checks anywhere in the UK, including Hounslow. Always ask to see the engineer's Gas Safe ID card — you can verify it on the official register.
