Landlord Gas Safety Certificates in Hertfordshire and London

As a landlord, you are legally required to have all gas appliances, pipework and flues in your rental property inspected every 12 months by a Gas Safe registered engineer.

At 1st Avenue, we make the process as straightforward as possible. Our Gas Safe registered engineers carry out a thorough inspection of your property's gas installations and issue your CP12 certificate on the same day - keeping you compliant and your tenants safe.

Failing to hold a valid landlord gas safety certificate is a criminal offence and can result in significant fines. We offer flexible booking including evenings and weekends to work around your tenants' schedules, and we serve landlords across Bushey, Hertfordshire and London.

Once the inspection is complete, we will provide you with a copy of the certificate for your records and, where required, a copy for your tenant. We can also set up annual reminders so your property never lapses out of compliance.

Landlord Gas Safety Certificate FAQs

Are landlord gas safety certificates a legal requirement?

Yes. Under the Gas Safety (Installation and Use) Regulations 1998, landlords must have every gas appliance and flue in a rented property checked annually by a Gas Safe registered engineer, and must give the tenant a copy of the certificate. Failing to do so carries serious penalties.

How often do I need a CP12 certificate?

Every 12 months. You can have the check done up to two months before the current certificate expires without losing the original renewal date, which makes it easy to keep a portfolio aligned on the same annual cycle.

How much does a landlord gas safety certificate cost?

The cost depends on how many gas appliances are in the property. A single-boiler flat is at the lower end, while a house with a boiler, a gas hob and a gas fire costs more. We offer reduced rates for multiple properties booked together and quote clearly before attending.

What happens if an appliance fails the inspection?

We will make the appliance immediately safe — capping it off if necessary — and explain in writing what failed and why. You will get a clear quote for any remedial work. We never exaggerate a fault to generate work; you get the honest position.

Do I need a certificate for an empty property?

If the property is not currently let you do not need a valid certificate for that period, but you will need one in place before a new tenancy begins. Most landlords find it simpler to keep the annual cycle running rather than let it lapse between tenants.
