Gas Interlock Systems

We supply and fit Gas Interlocking Systems (GIS) that are now legally required in commercial kitchens.

A Gas Interlock checks the kitchen extract fan is running before allowing gas in to the kitchen. If the fan stops, it will cut off the gas supply.

Do I need a gas interlock?

You will need a gas interlock in the following circumstances*:

  • On installation of a completely new extraction/ventilation canopy
  • On installation of a completely new gas pipework run
  • On installation of a completely new cook line or layout

With any fitting of Category ‘B’ equipment e.g. combination ovens, deep fat fryers, grills, charcoal griddles. This includes replacements to an existing layout
* This is only general information and not a statement of law, always consult a COMCAT Gas Safe engineer. Most restaurants, takeaways, cafés and pubs will need a gas interlock to comply with current standards.
