Gas Interlock System

Ensure Safety & Compliance with Professional Gas

Interlock Systems

In every commercial kitchen, safety and regulatory compliance are non-negotiable. If your kitchen operates with any Type B gas appliance—such as a combination oven—it is a legal requirement to have a compliant gas interlock system installed.

At NCE, we specialise in the installation, maintenance, and repair of gas interlock systems designed specifically for commercial catering environments. Our goal is to help your business meet all safety standards while keeping your kitchen running efficiently and reliably.

Why a Gas Interlock System Is Essential

A properly functioning gas interlock system is more than a regulatory requirement—it’s a critical safeguard. It ensures your ventilation systems are operating correctly before allowing the gas supply to open, preventing dangerous gas leaks, fire risks, and exposure to carbon monoxide. By integrating your gas supply with your extraction and airflow systems, gas interlocks help protect your staff, customers, and premises.

Whether you’re operating a single-site café or managing a large catering facility, NCE can design and install a solution that fits your kitchen’s layout, equipment, and compliance needs.

Gas interlock systems are mandatory for all commercial kitchens operating gas appliances, including:

  • Restaurants and Takeaways
  • Hotels and Resorts
  • Cafés and Coffee Shops

Legal Requirements for Gas Interlock Systems in the UK

Under British Standard BS6173, all commercial kitchens using gas appliances must have a functioning gas interlock system. This system ensures that gas flow is only permitted when mechanical extraction and ventilation systems are operating properly.

These regulations are enforced to prevent:

  • Dangerous gas build-up
  • Carbon monoxide exposure
  • Fire and explosion risks


Failure to comply can lead to hefty fines, potential business closure, and increased safety risks for your team and customers.

Ensuring your gas interlock system is installed, maintained, and tested regularly is not only a legal requirement, but a responsible business practice. Regular inspections also help identify wear or faults before they become serious issues, keeping your kitchen safe and compliant year-round.
