What is a CP12 certificate?
A CP12 certificate, also known as a Gas Safety certificate, is a legal document that private landlords in the UK must obtain every year. It confirms that all gas appliances, flues, and related systems in a rental property have been inspected by a Gas Safe registered engineer and are safe to use.
At Lime Heating, we help Milton Keynes landlords meet this crucial safety obligation with expert checks and digital certification.
Who needs a CP12?
If you’re a private landlord in Milton Keynes (or anywhere in England), the law requires you to:
Get a CP12 certificate every 12 months for each rental property with a gas supply
Provide a copy of the certificate to your tenants within 28 days
Supply a copy to new tenants before move-in
Retain copies for at least 2 years
What does the CP12 certificate include?
A typical CP12 form will list:
The address of the property checked
A description of each gas appliance and flue
Any issues found and recommended actions
The date of inspection
Details of the Gas Safe registered engineer, including registration number and signature
A clear statement confirming the appliances have passed safety checks
What happens if you don’t have one?
Failing to obtain a valid CP12 certificate could result in:
Fines of up to £6,000 per property
Voided landlord insurance policies
Legal action or imprisonment in serious cases
Risks to tenant safety from gas leaks or carbon monoxide exposure
Gas safety is not just a box-ticking exercise—it’s a legal responsibility and a moral duty.
