What Is a Gas Landlord Certificate (CP12)?

A Gas Landlord Certificate, also known as a CP12 Gas Safety Record, is a legally required document for all rental properties in the UK that have gas appliances or pipework. Issued after a safety check by a Gas Safe registered engineer, the certificate confirms that all installations are safe to use.

It includes:

  • Details of each gas appliance, pipe, and flue inspected
  • Results of gas tightness, pressure, ventilation, and flue tests
  • Any identified defects and recommendations
  • Engineer details, including Gas Safe registration number and signature
  • Date of inspection and expiry date (valid for 12 months) 

Landlords must provide tenants with a copy of this certificate within 28 days of completion—or before a new tenant moves in

Why It Matters

  • Legal requirement: The Gas Safety (Installation and Use) Regulations 1998 require landlords to carry out annual checks and generate a CP12 Certificate
  • Tenant protection: Ensures appliances are checked for safety, reducing risk of gas leaks or carbon monoxide poisoning.
  • Maintaining rights: Without a valid certificate, landlords may face significant fines—or even lose the right to serve a Section 21 eviction notice

Typical Costs

The cost varies depending on the number of gas appliances and location. In Kent and the South East, average prices are:

  • £60–£100 for a property with 1–2 gas appliances
  • £80–£120+ for properties with 3+ appliances

Additional appliances may incur £10–£20 per appliance, and rates are generally higher in London and the South East

Frequently Asked Questions

1. How often does a landlord gas safety (CP12) certificate need renewing?

By law, landlords must schedule a safety inspection every 12 months for all gas appliances, flues, and pipework within their rental property. The resulting CP12 certificate is valid for 12 months and must be renewed annually to maintain legal compliance. It’s recommended to book the next inspection about 2 months before expiry to avoid gaps.

2. What happens if I don’t have a valid CP12 certificate?

Failing to obtain or renew a CP12 certificate is a criminal offence. Landlords may face fines up to £20,000 per property, invalid property insurance, legal action from tenants, and in serious cases, prosecution or a ban from renting. A CP12 is also required before serving a valid Section 21 eviction notice.

3. What does the inspection involve, and who can issue a CP12 certificate?

Inspections must be carried out only by a Gas Safe registered engineer. During the check, the engineer examines all gas appliances, pipework, flues, ventilation, and safety devices. Any defects found must be repaired before a valid certificate is issued. The CP12 record includes the engineer’s registration details, appliance list, test results, and expiry date.
