Do I need a CP-12 (Gas safety certificate)
By LM Plumbers 2025
What is a CP-12 and why do I need one?
As this is also a question that we get asked let’s start here by explaining exactly what a CP12 is. A CP12 also known as a landlord gas safety certificate is a certificate that is regulated by the regulatory body Gas Safe.
The UK government has made it a legal requirement for landlords to obtain a CP12 every year to ensure that the rented property is Gas safe.
Only Gas Safe engineers who are registered with the regulatory body can carry out the gas safety check and provide the certificate, if the check is carried out by a non-gas safe engineer then it will be invalid and the landlord will be legally responsible for any issues resulting from a faulty gas appliance.
When a new tenant moves into one of your properties, we would recommend that you get a new gas certificate as tenants are legally entitled to request a gas safe certificate from you as the landlord before they move into the property. harm caused by a faulty gas appliance within their property.
