What a CP12 covers — and why it's not optional
The Landlord Gas Safety Record (still commonly called a CP12, after the old British Gas form number) is the document a Gas Safe registered engineer issues after the annual inspection of all gas appliances, flues, and pipework in a let property. The check covers operational safety of each appliance, gas tightness of the installation, the integrity of flues and ventilation, and the standing and working pressure of the system.
Under the Gas Safety (Installation and Use) Regulations 1998, landlords must arrange this check at intervals of no more than 12 months, must keep records for at least 2 years, and must provide a copy to existing tenants within 28 days of the check and to new tenants before they move in. Failure to comply is a criminal offence and one of the most common reasons for prosecution by the HSE in the rental sector.
CP12 alone, or with a boiler service?
The CP12 is an inspection only. It tells you whether the appliances are operating safely on the day of the visit. It does not extend the boiler's life, descale the heat exchanger, clean the burner, or replace any consumables. A boiler service is the maintenance work that does those things, and it's typically required to keep the manufacturer's warranty valid.
Most landlords do both at the same visit because the engineer is already on site, the cost saving is meaningful (one callout instead of two), and the boiler service result is appended to the same record. The FixQuotes brief asks every engineer to quote both options — CP12 only, and CP12 plus service — so you can pick on price.
Timing the check — and the 'two-month grace window'
The 12-month clock can be tricky. From 6 April 2018, regulations allow the check to be carried out in the two months before the existing certificate expires without restarting the clock — so a certificate dated 1 March 2026 originally issued on 1 March 2025 still counts as 'within 12 months' even if you've now had two checks in that calendar year.
In practice this means you can plan the check for a tenant-friendly window without losing time. If you're between tenancies, do it in the void; if not, give 24-hour written notice as required by Section 11 of the Landlord and Tenant Act 1985.
What a comparable quote includes
Every quote we return for this job type uses the same template, so you can compare like-for-like. You’ll see:
- Engineer's Gas Safe registration number — verifiable on gassaferegister.co.uk
- Inspection of every gas appliance in the property (boiler, hob, fire, instantaneous heater)
- Gas tightness test, flue integrity check, standing/working pressure
- Issued Landlord Gas Safety Record (CP12) — usually emailed within 24 hours
- Optional boiler service quoted separately so you can compare bundle vs CP12-only
- Any defects flagged with classification (immediate danger / at risk / not to current standards)
- Public liability insurance confirmation
- Ex-VAT pricing and access requirements (parking, key pickup)
Gas Safe — and verifying your engineer
Any work on natural gas or LPG appliances in a domestic property must be carried out by a Gas Safe registered engineer with the relevant categories on their card (e.g., CCN1 for core domestic, CKR1 for cookers, CEN1 for central heating boilers). FixQuotes only dispatches gas jobs to engineers we've confirmed are currently registered with the relevant categories. Their registration number is in every quote — you can cross-check it on the Gas Safe Register search before authorising the visit.
Where works require legally regulated qualifications (for example Gas Safe registration for gas works, or Part P competence for fixed electrical work), users should verify the contractor's credentials directly before authorising the work.
Common questions
How much does a Landlord Gas Safety Certificate cost?
For a typical UK property with a single boiler and one or two additional gas appliances, CP12 quotes usually come back in a £55–£100 range. London and the South East sit at the higher end. Adding a full boiler service typically takes the combined price to £120–£180. Your FixQuotes quotes show the actual local market for your specific property.
How quickly can the check be done?
Routine CP12 visits are usually scheduled within a week. If your existing certificate expires soon, flag it as urgent in the brief and we prioritise dispatch — most local engineers can fit in a check within 2–3 working days.
What if the engineer finds an unsafe appliance?
The engineer must classify any unsafe appliance as Immediately Dangerous (ID) or At Risk (AR) and, with your or the tenant's permission, can disconnect ID appliances. The CP12 records the issue. Remedial work is quoted separately — FixQuotes can re-brief the repair if you want competitive quotes on the fix.
Do I need a CP12 if there are no gas appliances?
No. If the property is fully electric (no gas boiler, no gas hob, no gas meter), there is no requirement for a CP12. You'll still need an EICR for the electrical installation under the 2020 regulations.
Does the CP12 cover the gas hob and the cooker?
Yes — every gas appliance owned by the landlord. Tenant-owned appliances (e.g., a cooker the tenant brought with them) are not the landlord's responsibility, but the connection to those appliances and the gas pipework up to the appliance still are.
Can I bundle CP12, EICR, and EPC into one job?
Yes. Send a single brief mentioning all three certificates. Some contractors hold all relevant qualifications; others coordinate with partner trades. Quotes will come back as one combined visit or as separate visits, depending on the contractor.
