Commercial Gas Safety Certificate (CP17)

Here’s why a CP17 Commercial Gas Installation Safety Certificate is essential for landlords and business owners in the UK:

1. It’s a Legal Obligation

• Under the Gas Safety (Installation and Use) Regulations 1998, if you own or operate a commercial property, you're legally required to:
  • Have your gas installation pipework inspected annually.
  • Obtain a CP17 certificate, issued by a Gas Safe registered engineer qualified in commercial systems.

2. Ensures Pipework is Safe and Leak-Free

• Over time, commercial gas pipework can:
  • Corrode
  • Suffer from joint wear
  • Develop slow leaks
• The CP17 certificate confirms the pipework passes tightness tests, and there are no dangerous leaks or weaknesses in the system.

3. Prevents Dangerous Incidents

• A gas leak in a commercial setting (e.g. a restaurant, factory, warehouse, or office block) poses serious risks:
  • Explosions
  • Fires
  • Carbon monoxide exposure
  • Business closure and evacuation
• Annual pipework checks help catch issues before they become emergencies.

4. Protects Your Business and Staff

• Ensures your gas system complies with health & safety laws — helping avoid:
  • Fines
  • Insurance voidance
  • Legal claims
  • HSE enforcement or shutdowns
• Maintains a safe environment for your employees, tenants, and customers.

5. Required for Insurance and Audit

• Many commercial insurers and local authorities require valid CP17 certification.
• It’s often part of your business’s compliance and audit documentation.

6. Needs Annual Renewal

• The CP17 must be renewed every 12 months.
• Any changes to your gas installation (e.g. extensions or renovations) may also require a new CP17.
