Check both appliance specifications
A separate oven and hob can have different connection requirements from a freestanding cooker or the equipment they replace. Obtain the model numbers and manufacturer installation information for both items, not only their sales-page dimensions.
Some products have particular supply options or configuration requirements. Do not generalise from a neighbour’s kitchen, a plug fitted to a different model or a statement that all induction hobs need the same arrangement.
Check the existing circuit and connection points
Check the existing circuit and connection points
The circuit, protection, connection arrangements and condition need to support the proposed equipment. A larger-looking cooker switch or a space in the consumer unit does not establish that the supply is suitable.
Tell the electrician what is currently installed and whether any other equipment uses the arrangement. If previous records are available, share them. You do not need to remove the cooker switch or consumer-unit cover to collect information.
Keep connections and controls accessible
Keep connections and controls accessible
Cabinets, drawers, an island and appliance housings can affect access to connections and controls. Give the electrician the final kitchen drawing, including the appliance positions and the manufacturer’s ventilation and installation requirements.
Clarify which contractor will fit the appliance physically and who will complete the electrical connection. A retailer’s delivery or installation package may have prerequisites; check these before choosing a fitting date.
Resolve the electrical plan before worktops are final
Resolve the electrical plan before worktops are final
Changing the appliance choice late can change the electrical brief as well as the cut-out or cabinet layout. Send model changes promptly rather than assuming a similarly sized replacement has the same requirements.
Ask the quotation to define the supplies, connection work, access and relevant checks and records. If a new circuit is proposed, agree the route, associated making good and applicable notification before the kitchen closes up.
What to share with your enquiry
- Exact oven and hob model numbers
- Manufacturer installation information
- Existing appliance and supply details
- Final kitchen or island layout
- Retailer, fitter and electrician responsibilities
Questions answered
Can a separate oven and hob share the old cooker supply?
That depends on the requirements of both new appliances and the existing circuit, protection and connection arrangement. The old cooker working does not establish suitability for the replacement pair. Have the proposed models checked together before fitting.
Ask Max about thisCan all induction hobs plug into a normal socket?
No. Products differ. Use the exact model’s installation instructions and appropriate professional assessment.
Ask Max about thisShould I check the supply before buying an induction hob?
Yes, if compatibility is uncertain. The exact hob specification needs checking against the installation before you commit to the product and fitting date. That leaves time to plan any circuit work and cable access before cabinets and worktops are completed.
Ask Max about thisWill changing from a gas hob to induction need electrical work?
It can. The proposed induction hob's requirements must be compared with the existing installation before fitting is booked. Provide the model and installation instructions, plus the separate oven details. Arrange any gas disconnection with a suitably qualified Gas Safe registered engineer and clarify the separate scopes.
Ask Max about thisWhat affects the cost of wiring a separate oven and hob?
The appliance requirements, suitability of the existing circuit, connection positions and cable access affect the work. A new circuit or changes behind finished cabinets can alter the scope. Compare quotations that include the same supplies, connections, testing, records and making good.
