Kitchen Rewire Leicester

Kitchen Design First, Wiring Second

Kitchen electrical work should be planned around the finished kitchen layout — not started before it is agreed. Appliance positions, socket heights, extractor location, isolator positions and circuit requirements all depend on knowing where each appliance will sit, which units are integrated, and how the kitchen fitter plans to install them.

Starting electrical first fix before the layout is finalised can result in:

• Socket and isolator positions that do not align with finished unit heights or appliance locations
• Appliance supplies that end up inaccessible behind fitted units
• Additional work to move or extend supplies if the layout changes after first fix

A review of the kitchen design before first fix begins avoids these problems and keeps the project running to schedule.

Working Alongside Kitchen Fitters

Leicester-Spark Ltd regularly carries out electrical first fix alongside kitchen installation teams. The typical sequence is:

1. Agree layout — electrical positions confirmed once kitchen design and appliance specifications are known.
2. Electrical first fix — cable routes, back boxes, circuit cabling to the consumer unit, all in place before units are installed.
3. Kitchen installation — kitchen fitter installs units; electrical supplies are already in the correct positions.
4. Electrical second fix — sockets, switches and appliance connections fitted once units and doors are in place and appliance positions are accessible.
5. Test and certify — full inspection, testing and certification on completion.

Coordinating the electrical schedule with the kitchen fitter avoids return visits to reposition supplies or correct routes after units are fixed.

Appliance Circuits: Hob, Oven, Microwave and Integrated Appliances

Electric hob

Electric hobs require a dedicated circuit, sized to the appliance's rated load in accordance with manufacturer instructions. A standard double socket is not suitable. The circuit rating and connection method are confirmed once the hob specification is known.

Oven

Whether an oven needs its own circuit depends on its rated current, what else is on the circuit, and the installation layout. In a combined hob and oven installation, separate circuits are often required. This is confirmed once the appliance specifications and kitchen layout are known.

Combination microwave/convection ovens and warming drawers

Combination microwave/convection ovens, warming drawers and compact integrated ovens can carry significant rated loads. Each may need a dedicated supply and should not be assumed to run from a standard worktop socket.

Fridge/freezer

A separate circuit for refrigeration is worth considering as a continuity precaution. If another kitchen circuit develops a fault and trips, refrigeration on its own circuit is not affected. This is a practical option to plan in when kitchen circuits are being laid out.

Accessible Isolation for Hidden Appliances

Integrated appliances — dishwashers, undercounter fridges, washing machines, ovens and hobs — require accessible means of isolation under BS 7671. The isolation point must be reachable without removing or fully displacing the appliance.

Depending on the kitchen layout and appliance type, the isolation point may be:

• A switched fused connection unit or isolator inside an adjacent cupboard
• A flex outlet plate accessible from a neighbouring unit
• An isolator above the appliance in an accessible position
• Another agreed accessible location within the kitchen design

The position should be agreed with the kitchen fitter before units are installed, since access routes are largely determined by the cabinet layout.

Why There Is Often No Room for Plugs Behind Appliances

Integrated appliances are designed to sit flush within the unit space — there is typically little or no clearance for a standard plug and socket directly behind them. Fitting one there usually means:

• The appliance cannot sit flush in the unit opening
• Doors or drawers will not close correctly
• The socket is inaccessible and cannot be isolated with the appliance in place

The connection point needs to be in a position that is accessible with the appliance installed, does not prevent flush installation, and allows isolation without removing the appliance. Agreeing this before first fix is part of why the layout needs to be confirmed early — it is standard practice in any planned kitchen installation, not a complication.

Sockets, Lighting, Extractor and Small Power

Above-worktop sockets

Socket positions above worktop level should be planned for the right number and height to suit the kitchen layout. Recessed or in-unit socket options need to be cabled at first fix, before units are installed — retrofitting a supply to these positions after the kitchen is in place is significantly more disruptive.

Under-cabinet lighting

Supplies for under-cabinet or pelmet lighting should be run during first fix. The cable routes are straightforward before units go in and considerably more involved afterwards.

Extractor fan or cooker hood

The electrical supply for the extractor or cooker hood is positioned in line with the unit it will be mounted on. Ducting and the extractor installation are not within our scope — but the electrical supply, connection point and any required switching are.

Consumer Unit, RCD/RCBO Protection and Certification

Kitchen work typically adds circuits to the consumer unit. Before starting, we check:

• Whether the consumer unit has spare capacity for the required circuits
• Whether existing circuits have suitable RCD/RCBO protection
• Whether a consumer unit upgrade is required before kitchen circuits can be added

Consumer unit upgrades in older properties are a common requirement ahead of kitchen work. If an upgrade is needed, it can be quoted and carried out as part of the same project. See our consumer unit upgrade page for detail.

All kitchen electrical installation work is inspected, tested and certified on completion. An Electrical Installation Certificate (EIC) or Minor Works Certificate is issued depending on the scope. Part P notification to Building Control is made where applicable. All prices include VAT at 20%.

Prices for kitchen electrical work are scope-dependent and confirmed following review of the kitchen plan and, where needed, a site visit.

Kitchen Rewires as Part of a Full House Rewire

If a full house rewire is planned alongside a kitchen installation, kitchen circuits can be included in the rewire scope. This avoids a separate first fix visit and ensures kitchen circuits are installed and certified as part of the new installation.

For full house rewire details and typical prices, see the house rewire Leicester page. For a rough estimate before a site survey, the house rewire cost calculator gives an indicative range.

Frequently Asked Questions

Do I need a kitchen plan before electrical work starts?

Yes. The electrical layout — socket positions, appliance supplies, isolator locations, lighting supply and extractor connection — all depend on knowing where each appliance will sit and how the kitchen will be installed. Starting first fix before the layout is agreed can result in supplies in the wrong positions, inaccessible isolation, or the need for remedial work if the design changes later.

Can sockets be fitted behind integrated appliances?

Generally not. Integrated appliances are designed to sit flush within the unit space, leaving little or no room for a standard plug and socket directly behind them. A socket in that position usually means the appliance cannot sit flush, the door or drawer will not close correctly, or the socket is inaccessible when the appliance is installed. The connection point should be in an adjacent cupboard, above the appliance, or another accessible position — agreed before the units are fitted.

Do hidden appliances need accessible isolation?

Yes. Integrated appliances — dishwashers, undercounter fridges, washing machines, ovens and hobs — require accessible means of isolation under BS 7671. The isolation point must be reachable without removing the appliance. Depending on the layout this may be inside an adjacent cupboard, via a flex outlet plate, or another agreed accessible location.

Does an electric hob need its own circuit?

Yes. Electric hobs require a dedicated circuit rated to the appliance load in accordance with manufacturer instructions. A standard double socket is not suitable for connecting a hob directly.

Should the oven be on a separate circuit?

This depends on the oven rating and what else is on the circuit. In a combined hob and oven installation, separate circuits are often required. The arrangement is confirmed once the appliance specifications and kitchen layout are known.

Can a microwave/convection oven need its own supply?

Combination microwave/convection ovens, warming drawers and compact integrated ovens can have significant rated loads and may each need a dedicated supply. They should not be assumed to work from a standard worktop socket.

Is a separate fridge/freezer circuit worth considering?

Yes, as a continuity precaution. If a kitchen circuit develops a fault and trips, refrigeration on a separate circuit is not affected. It is a practical option to consider when planning kitchen circuits.

Do you test and certify kitchen electrical work?

Yes. All kitchen electrical installation work is inspected, tested and certified. An Electrical Installation Certificate (EIC) or Minor Works Certificate is issued depending on the scope of work, and Part P notification to Building Control is made where applicable.

Can kitchen rewiring be included as part of a full house rewire?

Yes. If a full house rewire is planned alongside a kitchen installation, kitchen circuits can be included in the rewire scope. This avoids a separate first fix visit and ensures kitchen circuits are installed and certified as part of the new installation.
