How to Prepare Your Electrics Before a Kitchen Renovation

By Influx Electrical May 2026 6 min read

A new kitchen is one of the most satisfying home improvements you can make — but it's also one of the most electrically demanding. Kitchens are full of high-powered appliances, require specific circuit arrangements under building regulations, and the electrical work needs to happen before the fitters arrive, not after. Getting the sequencing right saves time, money and the headache of having a half-fitted kitchen sitting idle while you wait for an electrician. A kitchen renovation is also the ideal opportunity to upgrade your lighting to LED, add more sockets and — if your existing board is old — carry out a consumer unit upgrade at the same time.

Why the Electrics Come First

Kitchen electrical work is almost always a first-fix job — meaning cables need to be run, chased into walls and positioned before plastering, tiling or units go in. If you fit the kitchen first and then bring an electrician in, you'll likely be looking at units being removed, tiles being lifted and walls being re-plastered. The right order is always: electrics first, then kitchen installation.

Book your electrician early — ideally before you've even ordered the kitchen — so they can assess the existing installation and plan the first-fix work around the kitchen design.

What Electrical Work Does a Kitchen Renovation Typically Involve?

New or Upgraded Circuits

Modern kitchens place significant demand on the electrical installation. A full kitchen renovation usually requires:

  • Dedicated cooker circuit — a 32A or 45A radial circuit purely for the cooker or range, with a cooker control unit. This must be on its own circuit breaker
  • Dedicated fridge/freezer circuit — best practice is a separate circuit so the fridge isn't affected by a tripped breaker on the ring main
  • Dishwasher spur — a fused connection unit or socket positioned in the unit void
  • Washing machine spur — if the washing machine is in the kitchen, a dedicated outlet is recommended
  • Ring main or radial circuit for sockets — kitchens need plenty of sockets, typically positioned above worktops and inside unit voids

Lighting

Kitchen lighting has evolved significantly. Most renovations now include:

  • Recessed LED downlights on the main ceiling circuit
  • Under-cabinet LED strip lighting on a separate switched circuit
  • Extractor fan wiring — the fan should be on a suitable circuit and, if it has a run-on timer, wired accordingly

Extraction

If you're installing a new cooker hood or extraction system, the wiring needs to be in place before the hood is fitted. Ducted extraction requires a route through the wall or ceiling — plan this early.

Consumer Unit Upgrade

If your existing consumer unit is old, doesn't have RCD protection or doesn't have spare ways for the new circuits, a consumer unit upgrade is often carried out at the same time as a kitchen renovation. It's much more economical to do both together than to return later.

Don't assume your existing installation is adequate. Older properties may have ring mains that are already at their limit, undersized cooker circuits or no spare capacity in the consumer unit. A pre-renovation electrical assessment identifies these issues before they become problems mid-project.

Building Regulations — What Requires Notification?

Electrical work in kitchens falls under Part P of the Building Regulations. The following work in a kitchen must be either carried out by a registered competent person (who self-certifies the work) or notified to your local building control authority:

  • New circuits
  • Consumer unit replacement
  • Addition of sockets to an existing circuit near a sink or within a certain zone

Using a registered electrician — such as one registered with NAPIT or NICEIC — means the work is self-certified and you receive an Electrical Installation Certificate on completion. This is the documentation you'll need for building control, for your home insurance and when you come to sell the property. We are NAPIT registered and handle all certification and notification as part of the job.

Selling your home later: Buyers' solicitors routinely ask for electrical certificates for kitchen work. If the work was done without proper certification, it can delay or jeopardise a sale. Always get the paperwork.

The Right Order — A Simple Timeline

  • 1
    Plan the kitchen layout and appliance positions Before any electrical work is quoted, you need to know where units, appliances and sockets will go. Share the kitchen plan with your electrician so they can position outlets correctly.
  • 2
    Electrical survey and quote Your electrician assesses the existing installation, confirms what new circuits are needed and quotes for the first-fix and second-fix work.
  • 3
    Strip out the old kitchen Old units come out and the wall surface is exposed, making it easy to run new cables and chase out channels.
  • 4
    First-fix electrical work Cables are run, back boxes are fitted and consumer unit work is carried out. Walls are then plastered and tiled.
  • 5
    Kitchen installation Units, worktops and appliances go in. Your electrician will have positioned outlets so they land in exactly the right place.
  • 6
    Second-fix electrical work Sockets, switches and faceplates are fitted and tested. The cooker, hob, dishwasher and other appliances are connected. Lighting and extraction are commissioned.
  • 7
    Certification An Electrical Installation Certificate is issued covering all the new work, notified to your local authority where required.

How Much Does Kitchen Electrical Work Cost?

The cost varies depending on the scope of work, the condition of the existing installation and whether a consumer unit upgrade is needed. As a rough guide for properties in Darlington and the North East:

  • Basic rewire of existing circuits with new sockets and lighting: £300–£600
  • New circuits for cooker, dishwasher and ring main: £500–£900
  • Full first and second fix including consumer unit upgrade: £800–£1,500+

We'll give you a fixed price after a site visit — no surprises. Get in touch to arrange a free assessment before your renovation begins. If you're also curious about signs your existing wiring needs attention or whether a full rewire is worth considering at the same time, both guides are worth a read before you commit to a scope of work.
