What the job involves
A home charger is a new dedicated circuit from your consumer unit to a wall-mounted unit, plus the protection that circuit needs and the certification at the end. Total Skills describes a straightforward home installation as typically half a day (last reviewed June 2026, checked 6 September 2026).
- Survey — checking the available supply capacity, the earthing arrangement, the consumer unit and the cable route.
- New circuit — running armoured or suitably protected cable from the board to the charger position, through the wall or along the outside as required.
- Protection — the charger circuit needs its own overcurrent and earth leakage protection, plus protection against an open-PEN fault, which is either built into the charger or provided by a separate device or an earth electrode.
- Mounting and commissioning — fixing the unit, connecting it to your wi-fi where it is a smart charger, and setting it up.
- Testing and certification — an Electrical Installation Certificate for the new circuit and notification under Part P, since a new circuit is notifiable in England.
What drives the price
- Cable run length. The biggest variable. Elec-Mate prices 15m of 6mm² armoured cable at around £60 to £90 and 25m of 10mm² at £120 to £180 (page updated 10 June 2026), and the labour to route it climbs with every metre.
- Where the board is versus where the car parks. A board in the garage next to the drive is a cheap job. A board in an understairs cupboard at the front and a parking space at the back is not.
- Consumer unit capacity. If there is no spare way or the board is not suitable, that work gets added. Elec-Mate puts a consumer unit upgrade at £300 to £800 on top; Total Skills puts it at £500 to £1,200.
- Earthing arrangement. A TT system needs an electrode and its own testing. Open-PEN protection is required either way.
- Groundwork. Trenching to a detached garage or across a drive, with reinstatement, changes the job substantially.
- Tethered or untethered. Total Skills notes untethered units — socket only, you supply the cable — are typically slightly cheaper.
- Region. Total Skills puts London and the South East at £900 to £1,500 against £800 to £1,200 nationally.
