Landlord Gas Safety Checks (CP12)

GasSafe1 provides annual landlord gas safety checks (CP12 certificates) for rental properties, ensuring landlords meet their legal obligations and remain fully compliant with current UK gas safety legislation.

If you rent out a property with gas appliances, an annual gas safety check is not optional — it is a legal requirement.

Annual Gas Safety Check (CP12 Certificate)

An Annual Gas Safety Check, commonly referred to as a CP12, must be carried out every 12 months by a Gas Safe registered engineer.

During the inspection, we check:

  • Gas appliances provided by the landlord
  • Gas pipework and connections
  • Flue operation and ventilation
  • Appliance safety and correct operation
  • Signs of leaks, faults, or unsafe conditions

Once completed, a Landlord Gas Safety Record (CP12) is issued as proof of compliance.

Landlord Legal Responsibilities

By law, landlords must:

  • Arrange an annual gas safety check every 12 months
  • Use a Gas Safe registered engineer
  • Provide tenants with a copy of the CP12 certificate
  • Keep records of gas safety checks
  • Ensure all gas appliances and pipework are maintained in a safe condition

These responsibilities apply to all rental properties where gas is present — including houses, flats, and HMOs.

Failure to comply is a breach of current legislation.

What Is Included in a Landlord Gas Safety Check?

Our landlord gas safety checks include:

  • Inspection of all landlord-owned gas appliances
  • Gas tightness testing
  • Flue and ventilation checks
  • Safety device testing
  • Identification of defects or non-compliance
  • Issuing of CP12 documentation

If any issues are found, we’ll explain them clearly and advise on the required remedial work.

Consequences of Non-Compliance for Landlords

Failing to comply with gas safety legislation can have serious consequences.

These may include:

  • Fines and legal action
  • Invalidation of landlord insurance
  • Enforcement action by local authorities
  • Difficulty regaining possession of a property
  • Increased risk to tenant safety

Non-compliance is treated seriously because gas safety failures can result in serious injury or worse. This is why annual checks are enforced by law.

Who Needs a CP12?

You need a valid CP12 if you are:

  • A private landlord
  • A letting agent acting on behalf of a landlord
  • Renting out a single property or a portfolio
  • Operating an HMO
  • Providing gas appliances within the tenancy

Homeowners who live in their own property do not require a CP12 — this is a landlord-specific requirement.

Why Choose GasSafe1 for Landlord Gas Safety Checks?

  • Gas Safe registered engineers
  • Clear, compliant CP12 documentation
  • Flexible appointments
  • Suitable for single properties or portfolios
  • Straightforward advice on compliance

We understand landlord responsibilities and keep the process simple and stress-free.

Testimonials

 
Recently had my boiler replaced by this company and the whole experience was exceptional, from talking to Zoe in the office to then having Lee call at the house the very next day, they made me feel comfortable and confident straight away. Had my new boiler installed within a week and a few upgrades to radiators and valves, clean, tidy and exceptionally neat workmanship, very professional approach in all aspects, would highly recommend.
