What Is a Gas Safety Certificate (CP12)?

A gas safety certificate — formally called a CP12 — is a legal document issued by a Gas Safe registered engineer confirming that every gas appliance, flue and pipe in a rental property has been inspected and is safe for tenants to use. Without a valid certificate, Peterborough landlords are breaking the law.

Is a Gas Safety Certificate a Legal Requirement?

Yes, without exception. The Gas Safety (Installation and Use) Regulations 1998 require every landlord in England to arrange an annual gas safety inspection for each rental property that has a gas supply or gas appliances. Failing to comply can result in an unlimited fine, a six-month custodial sentence, and an inability to serve a Section 21 notice to end a tenancy.

How Often Must It Be Renewed?

Every 12 months. We advise Peterborough landlords to book 3–4 weeks before their current certificate expires. A small buffer prevents compliance gaps if engineers are busy, especially in autumn and winter when demand is highest.

What Does the Gas Safety Check Cover?

A CP12 inspection by 360 Maintenance Solutions covers:

All gas appliances (boiler, gas hob, gas fire, gas cooker)
Flues and ventilation pathways
Gas pipework and connections throughout the property
Emergency controls and safety shut-off devices
Combustion analysis and appliance performance testing

What Happens If an Appliance Fails?

If an appliance is found to be immediately dangerous (ID) or at risk (AR), the engineer must take it out of service. We will explain the fault clearly, issue the appropriate notice on your certificate, and provide a written quote for repair or replacement. Many straightforward repairs can be completed on the same visit.

Your Responsibilities as a Peterborough Landlord

Provide a copy of the current CP12 to existing tenants within 28 days of inspection
Give new tenants their copy before they move in
