What Is a Gas Safety Certificate in South London?
A CP12 records the annual gas safety check carried out by a Gas Safe registered engineer. It covers the gas appliances and flues supplied by the landlord. In South London, Croydon's new licensing schemes mean affected landlords need a current gas safety record for applications from 2026.
Gas Safety Rules At A Glance
Every 12 months
A Gas Safe registered engineer carries out an annual check under regulation 36.
Early renewal
A check within two months before the due date keeps the original expiry date.
Tenant copies
Existing tenants receive a copy within 28 days. New tenants receive one before moving in.
Records
Keep each record until two further checks are completed, giving at least two years of records.
Is a Gas Safety Certificate a Legal Requirement in South London?
Yes, for every South London landlord who provides gas appliances. Regulation 36 of the Gas Safety (Installation and Use) Regulations 1998 sets the landlord's annual gas safety duties. In Bromley, HMO requirements call for a record no older than one year, so the certificate age is checked at application.
Who Can Issue One and How to Check the Engineer
Only a Gas Safe registered engineer can carry out the check. Check the engineer's ID card and the appliance categories on the back, as the listed categories show the work covered by the engineer's registration. Use the Gas Safe Register search to check registration. ALC engineers carry Gas Safe ID, with the business registration number shown on request.
Why Gas Safety Compliance Works Differently in South London
South London covers ten boroughs, the largest of the five regions, from inner flats and conversions to outer suburban houses. Croydon's 2026 licensing change covers 14 wards alongside borough-wide additional HMO licensing, with applications from 25 September 2026. The schemes run to 31 August 2031. Five things make gas safety compliance in South London different:
What Makes South London Gas Compliance Different
1
Croydon
Selective licensing covers 14 wards, alongside borough-wide additional HMO licensing. Applications open on 25 September 2026 and schemes run to 31 August 2031.
2
Bromley
HMO requirements call for a gas safety record no older than one year. The issue date matters, not only the expiry date.
3
Southwark and Lambeth
Southwark has borough-wide additional HMO licensing and selective licensing across 10 wards. Lambeth's selective scheme covers close to the whole borough.
4
Inner and Outer South
Wandsworth, Lambeth, Southwark, Lewisham and Merton form Inner South. Croydon, Bromley, Sutton, Kingston and Bexley form Outer South.
5
Rental levels
Wandsworth has 36.3% of households privately rented, Lambeth 31.4% and Bromley 17.4%, compared with 30.1% across London (ONS Census 2021).
How Gas Safety Checks Work for South London Landlords and Agents
Inner South and Outer South Are Routed Differently
Inner South includes Wandsworth, Lambeth, Southwark, Lewisham and Merton, with flats, conversions and controlled parking. Outer South includes Croydon, Bromley, Sutton, Kingston and Bexley, with larger homes and HMOs. We group visits by area to plan practical appointment windows.
Getting Ready for Croydon's New Schemes
Croydon's selective licensing covers 14 wards alongside borough-wide additional HMO licensing. Applications open on 25 September 2026 and run to 31 August 2031. Have a current gas safety record before applying. The two-month early-check window helps keep renewal dates clear of the application process.
Age of Record, Not Just Expiry Date
Bromley's HMO requirements call for a gas safety record no older than one year. Each licence also carries a condition requiring a certificate from the previous 12 months when requested. An unexpired record differs from one issued within the last 12 months, making the issue date important.

What a South London Gas Safety Check Covers and What It Doesn't
The engineer checks every gas appliance and flue the landlord provides, including flue operation, air supply, operating pressure or heat input and safety devices. A gas safety inspection in South London also records any defect on the Landlord Gas Safety Record, and the record is still issued.
Covered by the gas safety check
NOT covered
If the Engineer Finds a Defect
A Gas Safe engineer records defects as Immediately Dangerous (ID) or At Risk (AR). With the landlord's or tenant's permission, an unsafe appliance can be disconnected or turned off. The South London record is still issued and lists the defect. Any remedial work receives a separate quotation.
Pipework and Carbon Monoxide Alarms
Installation pipework is not part of the annual appliance check, but landlords need to keep it maintained. Ask for a tightness test during the visit. Carbon monoxide alarms are required in rooms containing a fixed combustion appliance, excluding gas cookers.
