Frequently Asked Questions (FAQs) - Gas Safety Certificates (CP12)

Q: Is a Gas Safety Certificate legally required for homeowners?

A: While not a legal requirement for homeowners living in their own property, it is highly recommended to have an annual gas safety check for your own peace of mind and safety. Faulty gas appliances can be extremely dangerous.!

Q: How often do landlords need a Gas Safety Certificate?

A: Landlords in the UK are legally required to have a gas safety check performed on their rental properties every 12 months. A copy of the valid certificate must be provided to existing tenants within 28 days of the check and to new tenants before they move in.

Q: Who can issue a Gas Safety Certificate?

A: Only engineers who are registered with the Gas Safe Register are legally allowed to carry out gas work and issue Gas Safety Certificates in the UK. Always ask to see their Gas Safe ID card.

Q: What gas appliances are typically checked?

A: The engineer will check all gas appliances owned by the landlord (or homeowner if requested), which usually includes gas boilers, gas fires, gas cookers/hobs, and gas water heaters. They also check the visible gas pipework and flues.

Q: What happens if an appliance fails the safety check?

A: If an appliance is deemed unsafe, the engineer will explain the problem. Depending on the severity, they might issue a warning notice or, if it's 'Immediately Dangerous', they will disconnect the appliance with your permission to make it safe. The certificate cannot be fully issued until the necessary repairs are completed. BeFix can provide a quote for any required remedial work.

Q: How long does the gas safety check usually take?

A: A typical check for a standard property with a boiler, hob, and/or fire usually takes around 30-60 minutes, but this can vary depending on the number and type of appliances and the complexity of the installation.

Q: Do I need to be present during the check?

A: Someone over 18 needs to be present to grant the engineer access to the property and the gas meter. For landlords, this could be the tenant, provided they are aware and agree.

Q: How long is the Gas Safety Certificate valid for?

A: A Gas Safety Certificate (CP12) is valid for 12 months from the date of issue.
