If you're a landlord renting out a property, it is your strict legal duty to ensure all gas appliances, flues, and pipework are maintained in a safe condition. The cornerstone of this compliance is the annual Gas Safety Check (often referred to as a CP12 certificate).
What does a CP12 check actually involve?
It's not just a quick visual glance. A Gas Safe registered engineer will conduct rigorous tests, including:
- Checking the appliance for gas tightness (ensuring no internal leaks).
- Testing the standing and working pressure at the meter.
- Checking the burner pressure and gas rate against the manufacturer's data plaque.
- Using a flue gas analyser to ensure the boiler is combusting correctly and exhausting gases safely.
- Verifying that ventilation paths are clear.
What happens if you miss the deadline?
There is absolutely no grace period for a Gas Safety Certificate. If the certificate expires, you are committing a criminal offence. Furthermore, an expired CP12 completely prevents you from serving a valid Section 21 eviction notice, leaving you unable to regain possession of your property.
How much does it cost?
A standard CP12 inspection covering a boiler and a gas hob usually costs between £70 and £100. Always ensure the engineer is listed on the Gas Safe Register before booking.
