Landlord Gas Safety Certificates (CP12): London Guide
A clear guide to annual landlord gas safety checks, access, records, remedial work and preparing a London rental property.
Landlords must arrange an annual gas safety check for relevant gas appliances and flues by an appropriately Gas Safe registered engineer, keep the record and provide the required copy to tenants. The legal document is commonly called a CP12 or Landlord Gas Safety Record.
What the inspection covers
The engineer checks the safety of relevant gas appliances and flues within the scope of the visit. The record identifies the appliances checked, the results, any defects and the engineer’s details.
A gas safety check is not automatically the same as a full boiler service. Combining appointments may be practical, but the scope should be confirmed when booking.
Before the appointment
Good preparation reduces failed visits and delays.
- Confirm access with the tenant and keep a record of communications.
- Make sure the engineer can reach the boiler, gas meter and relevant appliances.
- Provide previous records and details of any recent faults or repairs.
- Ensure the correct landlord, property and tenant details are available for the record.
If a defect is found
The engineer will classify and explain safety concerns and may disconnect or make an appliance safe where required. Remedial work should be agreed and completed by a suitably qualified engineer. Never pressure an engineer to issue a satisfactory record where a safety issue remains.
Frequently asked questions
Is a CP12 required every year?
Landlords must arrange gas safety checks at the required intervals under current regulations. Keep a compliance calendar and confirm the due date shown on the previous record.
Can the boiler service and CP12 be done together?
Often yes, but they are different tasks. Ask the provider to confirm that both the service and the landlord gas safety record are included.
Can a tenant refuse access?
Landlords should make reasonable, documented efforts to arrange access and follow appropriate tenancy and legal procedures. Obtain legal advice for persistent access problems.
