Gas Safety Certificate (CP12) in Hillingdon
From enquiry to certificate: Gas Safety Certificate (CP12) for landlords in Hillingdon, handled by professionals holding the registration the law requires, with pricing confirmed before you commit.
Straight answer
If you let a property with gas appliances in Hillingdon, the law requires a gas safety check every 12 months, carried out by a Gas Safe registered engineer. The record it produces — the CP12 — goes to your current tenants within 28 days, and to new tenants before they move in.
Booking
What happens when you enquire
Live booking isn't switched on for Hillingdon yet — vetting comes before listing, in that order. Leave your details and you'll get a straight answer by email: whether we can cover the property, when, and for how much. No obligation either way.
Paperwork
Copies, retention and the renewal window
Treat the CP12 like an MOT: renew it in the two months before it lapses and the expiry date carries forward as if you'd waited. Copies are a legal duty, not a courtesy — 28 days for sitting tenants, before move-in for incoming ones — and the record should stay in your file for at least two years, ideally alongside its predecessors as a maintenance history.
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.
Pricing
What a CP12 costs
Two identical adverts can hide very different jobs — one boiler versus four appliances, ground-floor flat versus awkward loft access. That's why we show a guidance range rather than a headline teaser price, and confirm the real figure for your property before you commit. Bundling the annual boiler service into the same visit typically works out cheaper than booking it separately.
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.
Renting out in Hillingdon
Letting in Hillingdon: the practical points
For landlords in Hillingdon, 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 Hillingdon 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.
The law
The rules behind the certificate
The Gas Safety (Installation and Use) Regulations 1998 make the annual check a hard legal duty wherever in the UK you let, Hillingdon 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 London Borough of Hillingdon 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; London Borough of Hillingdon is the local housing authority for Hillingdon.
FAQ
What Hillingdon landlords ask us
Who can carry out a gas safety check in Hillingdon?
Only an engineer on the Gas Safe Register may legally carry out landlord gas safety checks anywhere in the UK, including Hillingdon. Always ask to see the engineer's Gas Safe ID card — you can verify it on the official register.
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.
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 is a CP12 gas safety certificate?
CP12 is the industry nickname for the Landlord Gas Safety Record — the document a Gas Safe registered engineer issues after checking each gas appliance, flue and pipework in a rental property. Landlords letting property in Hillingdon must have this check done every 12 months.
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 Hillingdon book both together because the engineer is already on site, but only the safety check is a legal requirement.
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.
