  1. What is a CP12 in common industry usage?

    Answer: The informal name for a Landlord Gas Safety Record — the annual gas safety check certificate for rented properties

    CP12 is the informal industry name (from the original CORGI form number) for the Landlord Gas Safety Record, the annual gas safety check certificate that landlords must provide to tenants for rented properties.

  2. What records must be retained by a landlord after a Landlord Gas Safety Check?

    Answer: Records must be kept for at least 2 years and a copy given to existing tenants within 28 days and to new tenants before they move in

    GSIUR Regulation 36 requires landlords to retain Landlord Gas Safety Records for at least 2 years and to provide copies to tenants: existing tenants within 28 days of the check, and new tenants before occupation.

  3. What is the Gas Safe Register's role regarding gas appliance safety incidents?

    Answer: Gas Safe Register receives incident reports from registered engineers and can investigate unsafe gas work, with powers to remove engineers from the register

    Gas Safe Register administers the registration scheme on behalf of HSE, receives reports of unsafe gas work, can investigate and remove engineers who carry out unsafe work, and promotes gas safety to consumers.

  4. What is the purpose of a gas work notification to Building Control?

    Answer: For certain gas works (e.g., boiler replacement) the installer must either notify the local authority Building Control or self-certify via a Competent Person Scheme to confirm compliance with Building Regulations

    Replacing a boiler or installing a new central heating system is notifiable work under Building Regulations. The installer can self-certify through a Competent Person Scheme (e.g., Gas Safe Registered Business) instead of notifying Building Control directly.

  5. What is the purpose of a Competent Person Self-Certification Scheme for gas work?

    Answer: To allow registered businesses to self-certify compliance with Building Regulations without separately notifying Building Control for each job

    Competent Person Schemes (such as the Gas Safe scheme) allow registered businesses to certify their own work as complying with Building Regulations, avoiding the need to notify Building Control separately for each notifiable job.

  6. What is the significance of the ACS (Assessed Competence Scheme) for gas engineers?

    Answer: ACS assessment provides evidence of technical competence in specific gas work categories, required for Gas Safe registration and to demonstrate competence under the GSIUR

    ACS (Assessed Competence Scheme) assessments are the primary route to demonstrating technical competence required for Gas Safe registration; engineers must be assessed in each category of gas work they wish to carry out and renew every 5 years.
