Changing from gas to induction can involve more electrical work than the appliance listing suggests. Your existing cooker circuit may be suitable, a model designed for a 13 A plug might meet your needs, or the hob you want may require a new circuit. Establish which applies before ordering the appliance or cutting the worktop.
The small electrical connection that powers a gas hob’s ignition does not prove there is a suitable supply for induction cooking. Similarly, having an electric oven below the hob does not automatically mean its circuit can supply both appliances.
If you are planning a kitchen change, our electricians in Aberdeen can assess the existing installation and explain the work needed. Start with the model you are considering, the oven details and a few photographs. Those details help turn a vague installation enquiry into a useful conversation.
Before changing from gas to induction choose the exact model
Two hobs with the same width and number of cooking zones can have different electrical requirements. The important information sits in the installation instructions and technical specification, not just the description on the retailer’s product page.
Find the full model number and download the installation guide. Look for the connection requirements, total connected load, any power management settings and the manufacturer’s instructions for the electrical supply.
Send that information to your electrician before committing to the purchase. A photograph of the showroom label can help, but a link to the actual model is better than a picture of a similar appliance.
For example, a household choosing between two four zone hobs might be comparing a model supplied with a plug against one intended for a higher powered connection. The difference affects the electrical work and the power available when several pans are cooking together.
AEG’s hob installation preparation guidance specifically asks customers switching from gas to check the electrical supply and appliance loading. That check belongs before the installation visit, when there is still time to change the plan.
Plug in and hardwired induction hobs offer different choices
Some induction hobs are designed to connect through a standard 13 A plug. Others require a hardwired connection installed by an electrician. Neither the size of the glass nor the number of zones tells you which arrangement applies.
NEFF’s T36CA50X1U product information provides an example of a hob marketed for a 13 A socket. This shows that a plug connection is a genuine option for certain models, rather than something that can be added to any induction hob.
| Hob arrangement | What to establish before buying |
|---|---|
| Model supplied for a 13 A plug | Whether the socket, circuit and installation position are suitable |
| Model with configurable power management | Which settings the manufacturer permits and what each means for cooking |
| Model requiring a hardwired connection | Whether the existing circuit meets the appliance’s requirements |
A plug does not remove the need for suitable fixed wiring. If the available socket is damaged, badly positioned or on an unsuitable circuit, that still needs attention.
Do not use an extension lead or adaptor to solve a connection problem. Ask for a permanent arrangement that suits the appliance and remains accessible for maintenance.
Understand what a lower power setting means at dinner time
Power management allows certain hobs to limit their total electrical demand. Bosch, for example, lists selectable connection limits for this induction hob. The available settings vary between models, so they must be checked in the relevant instructions.
The practical question is how the hob shares the available power between zones. At a lower total limit, you may be unable to use every zone at its highest setting together. Boost functions may also depend on what the other zones are doing.
Think about an ordinary evening in your kitchen. Do you usually heat one pan and simmer another, or regularly cook several dishes at once? Tell the supplier and electrician how you expect to use the hob, rather than choosing entirely by the advertised maximum output.
A suitable lower powered model can be worth considering where installing a new cable would be disruptive. However, understand the cooking compromise before treating it as a saving.
Any installer setting must match the assessed supply and the manufacturer’s instructions. Do not increase it later simply because you want faster cooking. The circuit may have been designed around that limit.
Can you reuse the existing cooker circuit
Possibly, but the answer needs inspection and testing. A cooker switch on the wall is useful information, not confirmation that everything behind it is suitable for the new appliance.
An electrician needs to identify what the circuit supplies and assess its cable, protective device, connections and condition. Cable length, installation method and surrounding insulation can affect its suitability. The visible end of a cable cannot tell the whole story.
The IET explains the need to assess an existing installation before additions or alterations. That includes relevant supply equipment and the earthing and bonding arrangements needed for the work.
This is why a universal answer such as “every induction hob needs this cable size” is unreliable. The appliance and the actual installation must be considered together.
Include the oven in the assessment
If you are keeping an electric oven, provide its model number as well. If you are replacing a freestanding cooker with a separate oven and hob, make that change clear from the start.
A shared circuit may be possible in a correctly designed installation. Other arrangements need separate circuits or changes to the connections. The electrician must assess the combined requirements and manufacturer instructions before deciding.
Avoid buying a larger oven halfway through the project without mentioning it. Even when the hob stays the same, changing the other appliance can change the electrical design and quotation.
Will the consumer unit need replacing
Changing from gas to induction does not automatically mean replacing the consumer unit. The assessment should establish whether the existing equipment can safely support the proposed work.
Your electrician will consider the available circuit protection, the board’s condition, suitable compatible devices and the installation’s capacity. A spare position is only one part of that assessment. It does not establish that the board can accept any chosen device or additional load.
Where residual current protection is required, its type must suit the equipment and installation. Modern electronic appliances make this a selection decision, not simply a question of whether a switch has a test button.
Tell the electrician about other substantial electrical loads, including an electric shower, EV charger or planned heat pump. These may affect the assessment of the home’s overall demand.
If changes are necessary, ask for the reason and the proposed scope in writing. Our consumer unit upgrade service in Aberdeen explains that work separately, so you can understand it without assuming it forms part of every hob replacement.
Check the space below the glass as carefully as the worktop
The visible dimensions are only the beginning. The kitchen fitter also needs the required cutout, appliance depth, permitted worktop thickness and clearances from surrounding materials.
An induction hob contains electronics beneath the cooking surface. Its installation must provide the clearances and airflow required by the manufacturer. A drawer immediately below, an oven underneath or a shallow worktop can therefore affect the plan.
Ask the fitter to check the whole arrangement before ordering replacement drawers or cutting stone. Include any separator panel or ventilation provision specified for that model.
AEG’s advice about drawers beneath induction hobs highlights the importance of correct installation and suitable storage below. A tidy fit is not enough if cupboards prevent the appliance from cooling as intended.
Also check access to the electrical connection and isolation arrangements. A connection hidden behind permanently fixed furniture can turn a later repair into a much bigger job.
For a hob with an integrated extractor, include the ducting or recirculation arrangement in the kitchen plan. The appliance may take up space that you expected to use for storage, and the fitter needs the correct model’s drawings.
Arrange the gas disconnection as part of the job
The gas hob needs to be disconnected and the redundant supply made safe by a Gas Safe registered engineer qualified for the relevant work. An electrician’s electrical qualifications do not establish competence to carry out gas work.
The HSE’s gas safety advice for homeowners explains the importance of using appropriately registered engineers. Check the engineer’s registration and the work categories on their identification card.
Agree who books that visit and when it happens. If a gas pipe occupies space needed by the new appliance or cabinets, resolve that before the worktop is fitted.
Removing the hob does not necessarily remove your home’s other gas requirements. Tell the engineer if the boiler or another appliance will remain in use, so the scope of the disconnection is clear.
Plan the cable route before the kitchen is finished
Where a new circuit is needed, the route from the consumer unit to the kitchen often determines the disruption. Agree it while cupboards, flooring and finishes are still being planned.
In an Aberdeen flat, the board may be in the hall with finished rooms between it and the kitchen. In another property, access below a floor or through a service space may offer a different route. A floor plan and photographs help explain the layout, but access may still need checking in person.
Ask where any visible cable containment would run. If you want everything concealed, say so before accepting the quotation and clarify who will repair plaster, decoration or flooring afterwards.
For an island hob, the cable route needs particular attention before the floor is laid. The position of the appliance, the connections and the kitchen furniture should be agreed together.
Existing finishes deserve the same planning as new ones. Tell the electrician about tiles you cannot replace, fitted flooring you want to keep and rooms where access is restricted. Those details help identify a practical route early.
What affects the cost of changing from gas to induction
The hob’s purchase price is only one part of the budget. Electrical preparation, gas work and alterations to the kitchen may be separate items, possibly supplied by different contractors.
A straightforward connection to a suitable existing circuit is a different job from installing a cable across the house. Comparing those two prices without comparing the scope will not tell you which quotation offers better value.
Ask your written quotation to identify:
-
The exact hob and oven models being allowed for.
-
Whether the existing circuit will be reused or a new one installed.
-
Any changes to protective devices or the consumer unit.
-
The agreed cable route and any visible containment.
-
Inspection, testing and the electrical paperwork included.
-
Gas disconnection, worktop work, disposal and making good, where included.
-
The total payable, including applicable VAT, and any stated exclusions.
If the quotation depends on an existing cable being suitable, ask how and when that will be confirmed. Establish what happens if the assessment reveals a defect or a different route becomes necessary.
A clear scope also makes it easier to compare a retailer’s installation package with a local electrician’s quotation. Check whether the retailer includes alterations to fixed wiring or expects a suitable connection to be ready on arrival.
Send useful information before requesting a quotation
You do not need to diagnose your own wiring. A small set of clear details helps the electrician understand the project and decide whether a visit is needed.
Send:
-
Your property address and postcode.
-
The hob’s full model number and installation manual link.
-
The oven model, if one will share the cooking area.
-
Photographs of the kitchen, existing cooker switch and consumer unit labels.
-
A photograph showing the cupboard or oven space beneath the hob.
-
A simple description of the route between the board and kitchen.
-
Your kitchen fitting dates and any changes to the appliance position.
Take photographs only of safely accessible areas. Do not remove covers from the consumer unit, open electrical connections or move a connected gas appliance to obtain a better picture.
Mention tripping, damaged fittings or a burning smell when making the enquiry. These need assessment in their own right and should not be hidden inside a request for an appliance swap.
Get the work in the right order
Agree the electrical design before committing to the final kitchen layout. Then coordinate the electrician, gas engineer and kitchen fitter around the same appliance information and dates.
Where new wiring is required, arrange the preparation before access is covered. The hob can then be connected once the cabinets and worktop are ready, followed by the appropriate inspection, testing and functional checks.
Before the job is finished, ask for the isolation arrangement to be explained and any configured power limit to be recorded. Keep the installation instructions, invoice and relevant electrical documentation together.
A new circuit requires an Electrical Installation Certificate. An addition or alteration to an existing circuit may instead be covered by a Minor Electrical Installation Works Certificate where appropriate. Ask which document applies to the actual work, rather than treating every electrical document as an EICR.
An EICR assesses the condition of an existing installation. It is not a substitute for the installation certificate required for a new circuit.
Questions homeowners ask before switching
Does induction mean the whole house needs rewiring
No. The need for wider work depends on the condition and suitability of the installation. An assessment might identify a suitable existing circuit, a local alteration or a new circuit. Ask the electrician to distinguish work needed for the hob from any separately recommended improvements.
Can I fit a more powerful hob later
Possibly, but the supply must be reassessed for the replacement model. Keep the circuit documentation and tell your electrician about future plans now. Extra capacity can sometimes be considered while access is available, although nobody should promise compatibility with every future appliance.
Will the hob work during a power cut
An induction hob needs electricity to heat the cookware. If cooking during a power cut matters to your household, consider that before switching. Do not assume solar panels or a home battery will run it; backup capability and the circuits supplied depend on the particular system.
Can the electrical work be done on delivery day
Only if the required preparation, access and other trades have been properly coordinated. A delivery slot does not guarantee that the existing circuit is suitable. For a new cable or altered kitchen layout, arrange the assessment ahead of delivery and agree a realistic fitting sequence.
What if I rent the property
Speak to your landlord or managing agent before ordering an appliance that involves changing the fixed wiring, gas connection or kitchen furniture. Agree the proposed work, permissions and responsibility for costs in writing. Give the approved appliance details to everyone involved so the installation matches the agreement.
