What is CP12 Gas Safety Certificate?

A CP12 Gas Safety Certificate is a legal document that confirms all gas appliances are deemed safe in a property. It’s crucial for landlords, especially if they rent out a property. This safety certificate is also known as a ‘landlord Gas Safety Certificate’. It is a detailed report that outlines the condition of the appliance/s in a property. The test must be conducted annually in every rented property by the landlord.

When is a CP12 Gas Safety Certificate issued?

A CP12 Gas Safety Certificate is issued after every gas appliance has been inspected and passed as safe in a property. Only a qualified heating engineer registered with Gas Safety is legally permitted to conduct these checks.

Every gas appliance in a property must be inspected every 12 months (annually) to verify that they continue to meet industry regulations/standards for safety purposes (or risk penalties).

If an appliance/s or installation does not meet the current safety requirements, an advisory note will be issued regarding the remedial work needed to meet regulations standards. In such a situation, you may have to service the gas appliance or install new appliances for your property. If the appliance/s meets with regulations, a CP12 certificate is issued, which will remain valid for the next 12 months.

Why is a CP12 Gas Certificate important?

A CP12 certificate shows that every appliance has complied with gas regulations and all are safe to use. The inhabitants of a property have the peace of mind and reassurance that all gas appliances within a property have been confirmed as safe to use.

However, in the event of a gas-related accident where the CP12 has expired or is non-existent, the landlord could be heavily fined or imprisoned. To avoid any penalties, check your CP12 expiry date and book an appointment if it has expired NOW! The courts do not look favourably upon an errant landlord if an accident has occurred through neglect. Serviceteam’s qualified Gas Safe Registered Engineers are on hand to test and service all gas appliances throughout Greater London and its surrounding areas.

Is a CP12 Landlord Certificate required for a commercial building?

Yes. A Landlord Safety Certificate (CP12) is legally required in the UK for commercial businesses.
It comes under the Commercial Gas Safety (Installation and Use) Regulations 2018. The landlord must appoint a gas safety registered engineer to complete these tests in a commercial property once every 12 months. Serviceteam’s Gas Safe Engineers are fully qualified to inspect both domestic and commercial buildings.

What does the gas engineer check during the inspection?

Once the engineer completes the inspection, you will get the certificate by email, usually within 48 hours (longer if completed over a weekend). We can inspect on the same day** (subject to timing and availability).

Frequently Asked Questions

Q: What is the validity period of a Gas Certificate CP12?

The gas safety certificate CP12 is valid only for 12 months from the date of issue, so it’s essential to check the expiry date. The certificate is valid only after the tests have been completed. All landlords must renew an expired certificate without fail and do so every year thereafter.

If you need any assistance, contact serviceteam to arrange a test in advance before the CP12 expires. A new certificate will be issued for the next 12 months if the gas appliance/s complies with the regulations.

You will be notified of any failures, and we will provide a quotation for any corrective work required.

Q: How long does it take to test the equipment?

Usually, it takes 30 to 45 minutes. However, it depends on the number of gas appliances on the property.

Q: How can I obtain a UK gas safety certificate?

By scheduling a meeting with a qualified Gas Safe registered engineer, you can get a gas safety certificate, also known as a Gas Safety Record form. All of your gas appliances and accessible heating pipes will be visually inspected to ensure they are in excellent working order. The pipework will also be tested for gas leaks.
