Gas safety certification is not just a legal formality โ€” it is the documented evidence that a Gas Safe registered engineer with the appropriate commercial qualifications has inspected your gas-fired appliances, verified they are safe to operate, and certified them as compliant with current gas safety regulations. For industrial and commercial operators, that documentation is essential for insurance, regulatory compliance, CQC assessments, HSE inspections, and the ongoing protection of staff and operations.

SMR Gas Maintenance engineers carry out gas safety inspections and issue certificates across the full range of industrial and commercial premises โ€” from factories and warehouses operating large-scale industrial heating and process equipment to care homes with stringent CQC compliance requirements, commercial kitchens requiring annual CP42 certification, and all general commercial premises across the North of England.

Gas Safety Certificates We Issue

CP15 โ€” Commercial Gas Safety Certificate

The CP15 is the standard gas safety certificate for commercial and industrial premises โ€” confirming that all gas appliances, pipework, flues, and associated equipment have been inspected and certified as safe.Every CP15 inspection carried out by SMR Gas Maintenance includes:

  • Visual inspection of all gas appliances and associated equipment
  • Gas pipework, connections, joints, and fittings inspected for leaks, corrosion, and deterioration
  • Adequate ventilation verified for all gas appliances
  • Flue and combustion gas testing where applicable
  • Emergency controls and isolation valves checked for correct operation and accessibility
  • Combustion analysis on all boilers and heating appliances
  • Gas meter installation and emergency cut-off verified
  • Full written CP15 certificate issued on completion โ€” clearly documented and ready for audit

Required annually for all commercial and industrial premises operating gas appliances โ€” including factories, warehouses, offices, schools, care homes, and all general commercial premises across the North of England.

CP16 โ€” Commercial Boiler Inspection Certificate

The CP16 is issued following detailed inspection of commercial and industrial boiler installations โ€” covering the boiler plant, heat exchanger, flue system, controls, pressurisation equipment, safety devices, and associated pipework.

Particularly relevant for the large industrial and commercial boiler plant found across the North of England's manufacturing, logistics, care home, hotel, and institutional sectors. Required by most commercial insurers as evidence of annual boiler compliance, and commonly required by facilities managers and commercial landlords as part of ongoing compliance management.

Every CP16 inspection includes full combustion analysis, heat exchanger inspection, burner strip and check, safety device testing, and a detailed written inspection report alongside the certificate.

CP17 โ€” Commercial Gas Installation Safety Report

The CP17 covers inspection and certification of existing gas installations in commercial and industrial premises โ€” including pipework systems, meter installations, emergency controls, and associated equipment โ€” where a formal assessment of the installation's safety and compliance is required.Commonly required for:

  • Commercial and industrial property acquisitions โ€” confirming the gas installation is safe before purchase or lease completion
  • Lease renewals โ€” landlord and tenant compliance obligations
  • Insurance renewals โ€” where insurers require evidence of gas installation assessment
  • Post-incident assessments โ€” following a gas escape, safety incident, or near-miss
  • Pre-recommissioning assessments โ€” where a gas installation has been out of service

We carry out CP17 inspections across the North of England for commercial landlords, property managers, facilities managers, industrial operators, and duty holders responsible for commercial premises compliance.

CP42 โ€” Commercial Kitchen Gas Safety Certificate

The CP42 is the annually required gas safety certificate for commercial kitchens โ€” covering all gas-fired catering appliances, the gas interlock system, ventilation, and gas pipework throughout the kitchen. A legal requirement for any business operating a commercial kitchen, regardless of size or sector.

Every CP42 inspection by SMR Gas Maintenance includes:

  • Inspection and testing of all gas-fired catering appliances โ€” ranges, ovens, fryers, grills, salamanders, combi ovens, pasta cookers, bratt pans, wok burners, and all other gas catering equipment
  • Gas interlock system proving test โ€” verifying correct operation of the proving sequence and confirming all interlocked appliances respond correctly to a ventilation failure
  • Gas pipework inspection and leak test throughout the kitchen
  • Ventilation assessment โ€” adequate mechanical extract ventilation verified
  • Emergency isolation valve location and operation check
  • Gas pressure check at appliances
  • Full written CP42 certificate issued on the day of inspection

Required by Environmental Health Officers during food business inspections, by insurers, and by licensing authorities. Applies to all commercial kitchen operators including restaurants, hotels, pubs, takeaways, care homes, schools, hospitals, and workplace canteens.


Gas Ventilation Interlocks & Pressure Proving Systems

Gas ventilation interlock systems โ€” also known as gas proving systems or kitchen interlocks โ€” are safety devices that automatically cut the gas supply to appliances if the ventilation system fails or is not running. A legal requirement under current Building Regulations and gas safety standards for commercial kitchens and certain industrial process environments.SMR Gas Maintenance install, commission, test, and certify gas interlock systems across the North of England โ€” covering:

  • New gas interlock system installation and commissioning
  • Annual proving test and certification
  • Fault diagnosis and repair of existing interlock systems
  • System upgrades where older interlocks no longer meet current standards
  • Full commissioning documentation and certification

We also install and commission gas pressure proving systems for industrial process environments where gas pressure verification is required as part of the process safety interlock sequence.


Pre-Commissioning & Gas Tightness Testing

Before any new or modified commercial or industrial gas installation can be brought into service, it must be strength tested, purged, and certified as gas-tight by a Gas Safe registered engineer. SMR Gas Maintenance carry out:

  • Strength testing of new gas installations to current Gas Safe standards
  • Gas tightness testing of existing and modified installations
  • System purging and safe recommissioning
  • Pre-commissioning certification for new commercial and industrial installations
  • Gas installation certification for new build commercial and industrial developments

We work alongside main contractors, M&E contractors, and project managers on commercial and industrial new build and refurbishment projects across the North of England.
