Introduction
If you own or manage a property in the UK, you may be wondering whether you need a Gas Safety Certificate, commonly known as a CP12. For landlords and business owners in West Molesey, Walton-on-Thames, and Hampton, this certificate is a legal requirement. Even for homeowners, booking yearly gas safety checks helps prevent dangerous leaks, failed appliances, and carbon monoxide risks.

What Is a Gas Safety Certificate (CP12)?
A Gas Safety Certificate (CP12) is an official document issued after a Gas Safe registered engineer checks your gas appliances, pipework, and flues.
The certificate confirms your gas system is safe and compliant.
You must have a CP12 if:
- You are a landlord renting out a property
- You manage HMO properties or flats
- You have commercial premises with gas
- You have new tenants moving in
- You are required to meet insurance or regulatory conditions
All rental properties must renew their CP12 every 12 months.
Why You Shouldn’t Skip a Gas Safety Check
Skipping a CP12 isn’t just unsafe — it carries serious legal and financial risks:
Legal Consequences
Failing to comply with the Gas Safety (Installation and Use) Regulations 1998 can result in fines and prosecution.
Higher Safety Risks
Without inspection, hidden faults may go unnoticed, increasing the risk of:
- Gas leaks
- Carbon monoxide exposure
- Appliance failure
- House fires
Insurance Issues
Many insurance policies require an up-to-date CP12.
Without one, claims may be rejected.
What a CP12 Inspection Covers
During a CP12 visit, a Gas Safe engineer will:
- Check all gas appliances (boilers, hobs, fires, cookers)
- Inspect flues and ventilation
- Test pipework for leaks
- Check pressure levels and burner operation
- Ensure safety devices work correctly
- Confirm everything complies with UK regulations
Once complete, you receive a Gas Safety Certificate (CP12) confirming the property is safe.

A legal requirement for every property you rent out.
