Installing a Gas Hob or Cooker: What’s Involved and Who Can Do It

A new gas hob or cooker is a straightforward upgrade — as long as it’s fitted by the right person. Here’s what a proper installation involves and who can legally do it.

At a glance

  • Only a Gas Safe engineer should fit a gas hob or cooker.
  • Fitting includes checking the supply, connection and ventilation.
  • It ends with a tightness test and safety check.
  • Freestanding cookers and built-in hobs differ slightly.

Who can fit it

By law, gas appliances must be installed by a Gas Safe registered engineer. It’s not a job for a general handyman or a keen DIYer — the risks of a leak or bad combustion are too high.

What the installation involves

The engineer checks the existing supply and connection point, fits the appliance (a bayonet hose for a freestanding cooker, a rigid connection for most built-in hobs), and confirms there’s adequate ventilation for the room.

Testing and sign-off

Every installation ends with a tightness test to confirm there are no leaks, and a check that the appliance burns correctly. Only then is it safe to use.

Built-in hobs vs freestanding cookers

A freestanding cooker usually connects via a flexible bayonet hose so it can be pulled out for cleaning; a built-in hob is connected more permanently and often coordinated with the worktop and kitchen fitter. Both are regulated gas work.
