The annual gas safety check tests every gas appliance, flue and pipework the landlord provides — tightness, operating pressure, ventilation, flue flow and safety devices — producing the Landlord Gas Safety Record (CP12).
Missing the CP12 is one of the most heavily penalised failures in housing compliance, and unsafe gas kills. Access is the hard part at portfolio scale: the process lives or dies on chasing appointments, no-access procedures and certificate collection.
Across Great Britain, landlords must have every gas appliance and flue checked annually by a Gas Safe registered engineer under the Gas Safety (Installation and Use) Regulations 1998, keep records for two years, and give tenants a copy.
Regulatory frameworks differ across the UK — see the city pages below for Scotland, Wales and Northern Ireland specifics.
Only if your in-house engineers are Gas Safe registered — registration is a legal requirement for any gas work, and no software changes that. Kaarr digitises everything around the check: scheduling, access, the CP12 record and resident copies.
You can complete the annual check up to two months early without shortening the certificate — the new record keeps the original expiry date, like an MOT.
You must be able to show all reasonable steps: letters, visits, escalation. Kaarr's no-access workflow records every attempt with timestamps and evidence.
A landlord gas safety check is a strict annual legal requirement, with the record (CP12) given to tenants within 28 days. Checks may be done in the 10–12 month window while preserving the expiry date. Only Gas Safe registered engineers can do this work — Kaarr manages the workflow, scheduling and certificates around your engineers or contractors; the app cannot replace the registration.
