If you’re a landlord in Kensington, keeping your property gas-safe isn’t just good practice — it’s the law. The Gas Safety (Installation and Use) Regulations 1998 require all landlords to renew their Gas Safety Certificate (CP12) every 12 months without exception.
At Citywide Plumbers, we help landlords across Kensington remain fully compliant with fast, efficient, and reliable inspections — and same-day certification. In this article, we explain how often the certificate must be renewed, the risks of delays, and how our expert engineers make the process seamless.
How Often Must Gas Safety Certificates Be Renewed?
The law is crystal clear: landlords must have a gas safety inspection carried out every year. This means:
-
The certificate is valid for 12 months
-
A new inspection is required before it expires
-
Records must be kept for at least two years
Citywide Plumbers recommends booking your inspection at least two weeks before the expiration date to allow time for any repairs or retesting if needed.
Does This Apply to All Rental Properties in Kensington?
Yes. Whether you’re letting out a single flat near Holland Park or managing multiple homes across Kensington and Chelsea, the annual renewal requirement applies to all rental properties with gas appliances.
You’ll need a valid certificate if your property includes:
Even if the property is currently vacant or in between tenancies, the certificate must still be renewed on time.
What Happens If a Landlord Fails to Renew on Time?
Failing to renew your Gas Safety Certificate puts you at risk of:
-
Legal penalties and fines
-
Invalidating insurance
-
Increased liability in case of an incident
-
Difficulty letting or renewing tenancy agreements
Local authorities in Kensington and Chelsea carry out routine checks and respond to tenant complaints. Keeping your certification up to date isn’t just a legal duty — it’s a safeguard for your tenants and your reputation as a responsible landlord.

Can I Renew Before the Certificate Expires?
Yes — and we encourage it. You can renew up to 2 months before the current certificate expires without affecting the original 12-month expiry date.
This gives you more time to address any issues that might arise during the inspection. Our Kensington engineers are happy to accommodate early renewals, especially for landlords with multiple properties.
