What Commercial Duty Holders Need to Manage
If your premises uses gas for heating, hot water, catering, LPG equipment or process appliances, gas safety is part of your business risk management. The exact record depends on the appliance and work carried out, but the duty to use competent engineers and maintain safe systems remains consistent.
Maintain gas equipment safely
Employers and duty holders must keep gas appliances, flues, ventilation and safety controls in a safe condition through inspection, servicing and maintenance.
Keep records available
Certificates, commissioning records, service notes and warning notices should be retained so landlords, insurers, facilities teams and enforcement officers can review them.
Act on unsafe findings
At Risk or Immediately Dangerous findings require prompt action. Equipment may need isolation until remedial work is completed and safe operation is confirmed.
Records Are Evidence, Not Just Paperwork
Commercial gas records help demonstrate that appliances have been checked, installation work was completed by a competent engineer, commissioning readings were taken, or pipework was tested before use. They also help the next engineer understand the history of the site.
Who Holds the Duty in a Commercial Building
Duties under the Gas Safety (Installation and Use) Regulations 1998 attach to whoever controls the premises and the appliances. In practice that means a landlord, a managing agent and an occupying business can each hold part of the responsibility for the same building. The safest approach is to map every appliance to an owner, agree who arranges inspection, and keep the resulting records in one place.
Enforcement is usually triggered by an incident, a complaint or a routine environmental health visit. Officers ask for evidence: current gas safety records, service history, commissioning documentation for recent installations and proof that the engineer held the right Gas Safe categories for the equipment.
A Practical Compliance Cycle
- Inventory the appliances. List every gas appliance, its location, fuel type and the record that applies to it.
- Confirm engineer competence. Check the Gas Safe registration covers the specific commercial categories on site.
- Schedule the inspection. Annual as a minimum, with additional servicing for heavy-use catering equipment.
- Act on classifications. Address At Risk and Immediately Dangerous findings before the appliance returns to use.
- File and diarise. Store records securely and set a renewal reminder well before expiry.
Documentation to Keep on File
Typical evidence includes the CP42 catering record, CP44 landlord record, CP15 commissioning sheet, CP16 purge and test certificate, CP17 isolation record, CP2 LPG leisure record, service reports, interlock test results and any remedial work invoices. Retaining several years of history helps demonstrate a consistent maintenance regime rather than a single snapshot.
