Booking
Booking in three steps
Our network doesn't yet show confirmed availability in Chester. 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.
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.
For landlords in Chester
Letting in Chester: the practical points
For landlords in Chester, 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 Cheshire West and Chester Council 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.
The law
Why Gas Safety Certificate (CP12) matters for Chester landlords
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; Cheshire West and Chester Council is the local housing authority for Chester.
FAQ
Gas Safety Certificate (CP12) questions, answered
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.
Who can carry out a gas safety check in Chester?
Only an engineer on the Gas Safe Register may legally carry out landlord gas safety checks anywhere in the UK, including Chester. 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 Chester?
The annual check itself is the same, but HMO licensing (administered by Cheshire West and Chester Council) 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 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 Chester must have this check done every 12 months.
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.
