—Fittings and installations

Connecting an electric cooker or hob

Cookers and hobs are among the highest loads in a kitchen. Their supply is planned around the appliance, not the other way round.

Most electric cookers, built-in ovens and induction hobs are connected to a dedicated circuit, sized for the appliance’s rating and protected at the distribution board. An isolator switch, usually above the worktop and away from the hob, allows the appliance to be switched off without pulling it out. Some smaller ovens plug into sockets; the installation manual states which.

Installation guides cover what a fitting or appliance needs from the electrics before it goes on the wall or ceiling.

Changing from gas to induction, or adding a second oven, often means checking whether the existing circuit is large enough. Positions of connection units must line up with the cabinetry, so they are decided with the kitchen layout.

01In short

The points that matter most

  • Usually a dedicated circuit

    Sized for the appliance’s rating.

  • Isolator within reach

    Above the worktop, not behind the appliance.

  • Check before upgrading

    Induction hobs can draw more than older cookers.

02Detail

What the connection involves

  • Circuit sizing

    Cable and protective device matched to the appliance rating and route length.

  • Isolator and outlet

    An accessible isolator and a connection unit placed to suit the cabinet layout.

  • Two appliances, one circuit

    Whether a separate oven and hob can share a circuit depends on their combined rating and the instructions.

  • Testing

    The circuit and the appliance connection are tested before first use.

03Checklist

Before the kitchen is fitted

  • Get the appliance manuals

    They state the required supply.

  • Mark positions

    Where hob, oven and isolators will sit.

  • Check the board

    For space and suitable protection.

04Questions

Questions people ask

Can an induction hob use the old cooker circuit?
Sometimes; it depends on the existing circuit’s size and the hob’s rating.
Where should the isolator go?
Somewhere reachable and not directly above the hob.
Can a built-in oven plug into a socket?
Some smaller models can; check the manual.
Why does the oven trip when it heats?
Element faults often appear when hot; see the guide on appliances that trip the breaker.
