Halifax has street after street of stone terraces climbing the sides of the Calder Valley, and a good number of them are let. The landlords we work for here range from someone with a single terrace to agents managing many, and the duty is identical for all of them: under the Gas Safety (Installation and Use) Regulations 1998, every gas appliance and flue in the property has to be inspected once a year by a Gas Safe registered engineer, and a Landlord Gas Safety Record — the CP12 — issued. Miss the date and you're outside the law, however good the boiler is.
What Haydn (Gas Safe no. 962740) actually does on the day is go through the property appliance by appliance — boiler, fire, cooker, water heater — checking each one, its flue, the pipework that's visible, the ventilation and the safety devices. The certificate is completed on site, not sent on later. Copies go to you and, if you use one, your agent; the tenant must have theirs within 28 days, and you hold the record for two years. Homes on exposed hillsides work their heating hard through a long winter, which is one reason a yearly look matters beyond the legal box.
Halifax is one of the larger towns on our Calder Valley round from our base on the Kirklees–Calderdale border, so we're over this way regularly rather than making a special trip — Elland and Sowerby Bridge are on the same run. For landlords with a handful of properties we'll group them where the diary allows, invoice an agent directly if that's the arrangement, and set a reminder so each renewal is flagged in advance. A boiler service can be added to the same visit. Quotes are free and written, with no hidden fees.
