CP12 landlord gas safety certificate in the UK — the annual gas safety record every rental property needs by law, issued same-day by Gas Safe registered engineers.
Officially RegisteredCP12 landlord gas safety certificate in the UK — the annual gas safety record every rental property needs by law, issued same-day by Gas Safe registered engineers.
A CP12 landlord gas safety certificate is the annual gas safety record every rental property in the UK must hold by law. It confirms that a Gas Safe registered engineer has inspected every gas appliance, flue and section of gas pipework in the property, and that each one is safe to use. We issue CP12 certificates across the UK from £120 + VAT, usually same-day or next-day, with the signed record emailed to you, your letting agent and your tenant on the day of the visit. Whether you own one flat, a portfolio of HMOs or a managed block, the process is the same: a fixed written price before we attend, a Gas Safe registered engineer on site, and a compliant landlord gas safety record in your inbox before the end of the day.
Boilers, gas cookers, hobs, gas fires and water heaters at your the UK property are individually checked for gas tightness, correct operating pressure and correct gas rate against the manufacturer's data plate.
We carry out flue flow and spillage tests and a combustion analysis on every open-flued and room-sealed appliance in the UK, so carbon monoxide risk is identified before it reaches your tenant.
Air vents, compartment ventilation and the visible gas installation pipework are inspected against current standards, with a tightness test on the whole system at your the UK property.
Each appliance is classified on the CP12 record. If anything in the UK is at-risk or immediately dangerous, we explain it plainly, isolate it safely with your permission and quote for the repair separately — never as a hidden add-on.
The Gas Safety (Installation and Use) Regulations 1998 place three duties on every landlord in the UK. First, arrange an annual safety check of all gas appliances and flues by a Gas Safe registered engineer. Second, give the tenant a copy of the CP12 landlord gas safety certificate within 28 days of the check, or before a new tenant takes occupation. Third, keep a copy of each record for at least two years. Failure to hold a valid CP12 is a criminal offence carrying unlimited fines and, in serious cases, imprisonment; it can also invalidate landlord insurance and block a Section 21 notice. We make compliance simple: we hold your renewal date, remind you a month before expiry, and re-inspect within the final two months of the current certificate so your annual date never drifts. Records for every the UK property we certify are stored digitally and can be re-sent to you, your agent or your insurer at any time.
