Induction Hob Installation Costs UK 2026 — What to Charge to Fit and Wire an Induction Hob

Why Induction Hobs Need More Than a Plug

A typical four-zone induction hob has a connected load of around 7–7.4kW. Some larger or flex-zone models push past 11kW. Even with the diversity and power management that most modern hobs apply, the manufacturer's installation instructions almost always call for a dedicated higher-rated circuit. In practice that means a 32A radial run in 6mm² cable from the consumer unit to a cooker connection unit (a flex outlet plate) behind or beside the hob, with a 45A double-pole cooker switch for isolation.

A small number of compact or single/double-zone hobs are rated at or below 3kW and can legitimately run on a standard 13A plug or fused connection unit — but these are the exception. Most hobs the customer has bought need hard-wiring. Always read the installation instructions for the specific model before you quote. The required circuit rating, cable size and isolation method are all stated there, and pricing off an assumption is how you end up doing free upgrade work.

Part P and Who Can Do the Work

Fixed electrical work in a kitchen — installing a new circuit, or in some cases altering an existing one — is notifiable under Part P of the Building Regulations in England and Wales. It must be carried out by a competent person registered with a scheme such as NICEIC, NAPIT or ELECSA, who can self-certify and issue the relevant certificate, or it must be notified to building control. Scotland and Northern Ireland have their own equivalent regimes.

This matters for your pricing and your liability. A kitchen fitter who is not a registered electrician should not be running new circuits or working in the consumer unit. The clean way to handle it is to either be qualified yourself or to bring in a registered electrician as a sub-contractor and build their cost into your quote. Either way, the customer should receive an Electrical Installation Certificate or Minor Works Certificate for the work. Make that part of your offer — it's a selling point, not just a legal box to tick.

Step One: Check the Existing Circuit

Before you can price anything, you need to know what's already there. The single biggest cost variable is whether the kitchen already has a suitable cooker circuit you can reuse. Many homes that previously had an electric cooker or an older ceramic hob will have a 32A or 40A cooker circuit terminating at a cooker switch and outlet plate — and if that circuit is in good condition and adequately rated for the new hob, the job becomes a straightforward swap.

• Cable size: Confirm it's 6mm² (or 10mm² for higher loads). A 2.5mm² ring spur is not a cooker circuit.
• Protective device: Check the rating of the existing MCB or RCBO at the board and that it matches the cable and the hob load.
• RCD protection: Modern installs require RCD/RCBO protection on the circuit — an older board may not have it.
• Condition: Look for signs of overheating at the connection unit, loose terminals, or undersized tails.
• Board capacity: Confirm there's a spare way if a new circuit is needed, and that the consumer unit itself is up to standard.

Where the existing circuit is suitable, you're looking at a low-labour disconnect-and-reconnect. Where it isn't — undersized cable, no spare way, an old rewireable fuse box, or no cooker circuit at all — the job grows, and so does the price.

What to Charge: 2026 Price Bands

Swap Onto an Existing Suitable Circuit

If there's an existing cooker circuit of the right rating and condition, fitting the new hob is mainly disconnecting the old appliance, connecting the new one at the cooker connection unit, testing and certifying. This is the cheapest scenario.

• Labour to swap onto an existing suitable circuit: £90–£180
• Includes disconnect, reconnect, test and Minor Works Certificate

Supply and Fit With a New Cooker Connection Unit

Where the circuit is sound but the outlet arrangement needs upgrading — a new cooker connection unit, a new 45A isolation switch, or relocating the connection point to suit the hob position — add the materials and the extra labour. The flex outlet plate and cooker switch are inexpensive, but the work of chasing, mounting and making good takes time.

• New cooker connection unit and isolation switch (parts): £20–£60
• Labour to fit and reposition: £100–£220

New Dedicated Circuit and Consumer-Unit Work

This is where the price jumps. If there's no suitable cooker circuit, you're running a new 6mm² radial from the consumer unit to the hob position, adding a way and an RCBO at the board, and possibly upgrading the board itself if it's a rewireable fuse box or lacks RCD protection. Cable runs across the property, lifting floors or chasing walls, and the level of making good all push this up.

• New dedicated circuit plus a spare way / RCBO: £200–£500+
• Full consumer-unit replacement (if board needs upgrading): £400–£700+ on top

Worktop Cut-Out

Where the hob is going into a worktop that hasn't been cut, or where the new hob is a different size to the old one, someone has to make the aperture. Many electricians don't do this — it's often the kitchen fitter's job — but if you're offering a complete supply-and-fit you need to price it in or sub it out.

• Laminate worktop cut-out: £40–£90
• Solid wood or composite: £80–£150
• Granite, quartz or other stone (specialist with the right tooling): £150–£350+

Removing the Old Hob

Removing the existing hob is usually quick but not free. Allow time for safe isolation, disconnecting the old appliance, and getting it out of the worktop — older gas hobs additionally need a Gas Safe registered engineer to cap off the supply, which is a separate cost the customer often forgets about. For an electric-to-electric swap, factor 30–60 minutes of labour for removal and disposal, and confirm whether the customer wants you to take the old unit away (recycling and waste disposal may carry a small charge).

Worked Examples

Price bands are useful, but customers understand quotes better when they can see how the numbers add up. Here are three realistic scenarios.

Example 1 — Straight Swap, Existing Circuit Good

Customer has bought a 7.2kW four-zone hob to replace a ceramic hob on an existing 32A cooker circuit in 6mm² cable, with RCBO protection at a modern board. You isolate, remove the old hob, connect the new one at the existing cooker connection unit, test and certify.

• Labour (swap, test, certificate): £140
• Sundries: £10
• Total: ~£150

Example 2 — New Connection Unit and Worktop Cut-Out

Existing 32A circuit is sound, but the new hob is wider than the old one and the connection point needs relocating. You fit a new cooker connection unit and 45A isolation switch, reposition the supply, cut the laminate worktop to suit, and make good.

• Labour (reposition, fit, test, certificate): £190
• New connection unit and isolation switch: £45
• Laminate worktop cut-out: £70
• Total: ~£305

Example 3 — New Dedicated Circuit From the Board

No usable cooker circuit. The kitchen ran the old hob off a fused spur that can't take the load. You run a new 6mm² radial from the consumer unit (a 12m run, partly under floorboards), add a spare way with a 32A RCBO, fit the cooker connection unit and isolation switch, and certify.

• Labour (run circuit, board work, fit, test, certificate): £340
• Cable, RCBO, connection unit, isolation switch: £90
• Making good (lifted floor, minor chase): £40
• Total: ~£470

What Drives the Cost

Two installations of the same hob can differ by £400 or more. The variables that move the price are predictable once you know what to look for:

• Existing circuit suitability: A reusable, correctly rated cooker circuit is the single biggest saving. No suitable circuit is the single biggest cost.
• Distance to the consumer unit: A short run in an open void is quick; a long run across the house, through joists or up walls, is hours of labour and more cable.
• Board space and upgrade: A spare way and modern RCBO protection is cheap. A full consumer-unit replacement to gain capacity or bring an old board up to standard adds £400–£700+.
• Worktop material for the cut-out: Laminate is fast; stone needs a specialist and the right tooling, and a mistake is expensive.
• Making good: Lifting and relaying floors, chasing and re-plastering walls, and tidying the cabinet run all take time that has to be priced.
• Old appliance type: An old gas hob needs a Gas Safe engineer to cap the supply — a separate trade and cost.

Quoting Tips — What to Check Before You Price

Induction hob quotes go wrong when the electrician prices off the customer's description rather than a proper look at the board and the existing supply. Before you commit a price, check the following:

• The hob's installation instructions: Confirm the required circuit rating, cable size and isolation method for that exact model.
• The existing supply: Cable size, protective device rating, RCD protection and physical condition.
• Consumer-unit capacity: Spare ways, board age and whether it meets current standards.
• The cable route: Distance to the board and what's in the way — floors, walls, units.
• The worktop: Whether a cut-out is needed and what material it is.
• The old appliance: Whether it's gas (needs Gas Safe) and who removes and disposes of it.

Spell out in your quote what is and isn't included — particularly the certificate, the worktop cut-out, and any consumer-unit work. A clear line-by-line quote that explains why a new circuit costs what it does will win more jobs than a single number that the customer can't make sense of.
