VAT · Digital certificate From £110 inc. VAT Digital certificate Gas Safe registered #9663 Family-run since 1986 12-month workmanship guarantee What we do ## Landlord Gas Safety Checks (CP12), done properly. Every landlord letting a property with a gas appliance has a statutory duty under the Gas Safety (Installation and Use) Regulations 1998 to arrange an annual gas safety check by a Gas Safe registered engineer, and to keep a copy of the certificate for two years. We do this every week for landlords across Stockport, and we make it easy. What it is A landlord gas safety check (often called a CP12 or Landlord Gas Safety Record) is a full inspection of every gas appliance and flue in the property, plus a tightness test on the gas supply. It's issued as a signed digital certificate, emailed to you for your records and to the tenant. Who it's for Any landlord with a gas appliance in a let property. That includes buy-to-let owners, letting agents managing on behalf of landlords, HMO operators, and short-let (holiday let) operators. Owner-occupiers are welcome too, same inspection, different paperwork name. When you need it Annually, before the previous certificate expires. If you're between tenants, it's the ideal time to book, the property is empty and access is straightforward. Why it matters Because the fine for non-compliance is enormous and the reputational damage worse. And because, much more importantly, a tenant living with an un-inspected gas appliance is a tenant at risk. A CP12 is not a form-filling exercise; it's a real safety inspection with real value. Book a service or repair ### Speak directly to the engineer. from £110 inc. VAT What happens if it's ignored ## The cost of putting it off. Landlords who let their CP12 lapse or accept a rushed check face several very real risks. ### Statutory non-compliance Operating a rental property without a valid CP12 breaches the 1998 regulations and can result in enforcement action and unlimited fines. ### Insurance issues Landlord insurance policies frequently require a valid gas safety certificate; a claim after a gas incident with an expired CP12 is unlikely to be paid. ### Tenant safety The whole point of the CP12 is that it identifies faults before they become dangerous. Skipped inspections are how avoidable CO incidents happen. ### Sale friction Selling a rental portfolio with gaps in the CP12 history is harder, buyers and solicitors ask for the paperwork every time. Common mistakes we see - Booking the cheapest CP12 without checking whether a proper combustion analysis was done. - Assuming the tenant has arranged the check. - Letting the certificate expire during a tenancy handover, every year, hundreds of landlords do this. Our process ## A clear five-step system. No guessing, no meter-running. Every job follows the same repeatable process, that's how the result stays consistent. 1. 01 ### Access arranged We coordinate access with you, the letting agent, or the tenant, whichever suits. 2. 02 ### Appliance inspection Every gas appliance in the property inspected against Gas Safe standards, boiler, gas fires, cookers, hobs. 3. 03 ### Combustion analysis Flue gas analyser used on the boiler and any gas fires, proper CO and combustion checks, not just a visual glance. 4. 04 ### Tightness test Full gas tightness test at the meter to verify no leaks on the supply pipework. 5. 05 ### Certificate issued Digital CP12 issued the same day, emailed to you and (where required) the tenant. Two-year retention on file. Why it's worth doing ## What you actually get. ### Statutory compliance One less thing on the landlord's to-do list, booked, done, certified. ### Same-week appointments Fits with tenant changeovers and inspection cycles. ### Digital certificate Instant PDF for your records, letting agent, or portfolio system. ### Service included A basic boiler service is included in every landlord gas safety check. ### Combined with contract Landlords on the maintenance contract get particularly good value paired with the annual CP12. ### Landlord-experienced engineer 40 years of working with landlords means paperwork, tenant liaison and access all handled smoothly. In depth ## The detail that matters. A CP12 isn't a certificate that can be issued from a photo, every element must be checked, in person, by a Gas Safe engineer. ### What's inspected Every gas appliance (boiler, fire, cooker, hob), the flue on each appliance, adequate ventilation, gas tightness across the supply, and appliance safety devices (flame supervision, oxygen depletion sensors, thermocouples). ### HMO and multi-tenant properties Houses in multiple occupation carry additional CP12 obligations and are covered in the same visit where the appliances are in one property. Larger HMO portfolios are scheduled block-by-block for efficiency. ### New tenancies A CP12 must be provided to a new tenant before they move in. Where the existing certificate is close to expiring, it's usually simpler to renew before the tenancy starts. ### Certificate retention Landlords must retain each CP12 for at least two years. We retain copies too, so if you need a lost certificate re-issued we can send it. FAQs ## Questions we hear every week.
