Booking
How it works
We're building coverage in Richmond upon Thames 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 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, Richmond upon Thames 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 Richmond upon Thames 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 Richmond upon Thames is the local housing authority for Richmond upon Thames.
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.
For landlords in Richmond upon Thames
Letting in Richmond upon Thames: the practical points
For landlords in Richmond upon Thames, 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 Richmond upon Thames 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.
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.
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
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.
Who can carry out a gas safety check in Richmond upon Thames?
Only an engineer on the Gas Safe Register may legally carry out landlord gas safety checks anywhere in the UK, including Richmond upon Thames. Always ask to see the engineer's Gas Safe ID card — you can verify it on the official register.
Are the gas rules different for an HMO in Richmond upon Thames?
The annual check itself is the same, but HMO licensing (administered by London Borough of Richmond upon Thames) usually requires you to provide the current gas safety record with your licence application and on request. Check your licence conditions for any extra record-keeping duties.
What happens if I let a property in Richmond upon Thames 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.
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 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.
