Gas Safety Certificates Across London for Landlords, Agents & Property Managers

Gas Safety Certificate is the everyday name people use for a gas safety record issued after the required checks have been completed. For rented homes, the document is properly called a Landlord Gas Safety Record and is often known as CP12. Commercial catering kitchens commonly use a CP42 record. The correct record depends on the premises and equipment being inspected.

CP12 is used for landlord-provided gas appliances and relevant flues in rented residential property. CP42 is commonly used for fixed commercial catering installations, such as restaurants, cafés, pubs and takeaways. A CP42 inspection may involve commercial cooking equipment, gas pipework, emergency isolation, ventilation, extraction and interlock arrangements. A domestic CP12 does not replace a commercial catering CP42.

Landlords, housing providers and some letting or managing agents need to arrange annual gas safety checks for gas appliances and flues they own and provide for tenant use. The management agreement should make clear who is responsible. The check must be completed by a suitably qualified Gas Safe registered engineer, and the resulting record should be kept with the property's compliance documents.

Relevant landlord-provided gas appliances and flues must be checked every 12 months. The next check can usually be arranged during the two months before the current due date while retaining the existing renewal date. Booking early gives more time to coordinate tenants, keys and access without leaving the inspection until the last few days.

Existing tenants should receive a copy of the completed gas safety record within 28 days. New tenants should receive the current record before moving in. Landlords should keep each record for at least two years. Electronic delivery can be convenient where the tenant can access it, but a paper copy should be provided when requested.

The engineer checks the agreed landlord-provided gas appliances and relevant flues using the procedure appropriate to each item. This may include safe operation, appliance condition, flue performance, ventilation, combustion and safety devices. The record identifies the appliances checked, their locations, the engineer's details, the inspection date and any safety-related defects found.

A CP42 inspection is shaped around the commercial catering installation. The engineer may check fixed cooking appliances, accessible gas pipework, appliance connections, emergency isolation, ventilation, extraction and gas interlock arrangements where applicable. The exact scope depends on the kitchen layout and equipment list, so photographs and appliance details should be supplied before the appointment.

No. Gas Safe registration is essential, but the engineer must also hold the correct categories for the appliance and type of work. An engineer qualified for domestic boilers may not be registered for commercial catering equipment. The engineer's Gas Safe ID card should show the relevant competencies for the premises, appliances and inspection being carried out.

The engineer follows the gas industry's unsafe-situations procedure. An appliance or installation may be classified as Immediately Dangerous or At Risk. Depending on the finding, it may need to be turned off, isolated and labelled Danger Do Not Use. The record can still show the defect, but the equipment should remain out of use until the required repair or replacement is completed.

No. A gas safety check confirms the safety points required for the record, while a service is a maintenance procedure that may involve cleaning, adjustment and checks recommended by the manufacturer. They can sometimes be booked together, but one does not automatically include the other. Parts, repairs and remedial work are separate unless clearly listed in the quotation.

The landlord's annual duty normally focuses on gas appliances and flues the landlord owns and provides for tenant use. Tenant-owned appliances are not usually part of the landlord's appliance check, although the landlord remains responsible for ensuring the associated installation and flue arrangements are safe where applicable. Any tenant-owned appliance to be included should be agreed before the visit.

The engineer cannot complete a meaningful record for equipment that cannot be accessed or checked. Locked rooms, missing keys, blocked appliances and unavailable tenants can lead to an incomplete visit or additional charge. Landlords should make reasonable efforts to arrange access, keep evidence of communication and ensure every agreed appliance, flue and inspection panel is available.
