How much does EV charger installation cost?

Cable run length is the main one. A charger on the wall next to the consumer unit is a short job. A charger at the far end of a driveway, or on a detached garage, means a long run of heavy cable, possibly trenching, and materials cost that scales with distance.

The state of your existing electrics is the second. A modern consumer unit with a spare way is straightforward. An older board with no capacity, or one that does not meet current requirements, may need upgrading first — and that is a genuine cost, not an upsell, though it is worth getting a second opinion if it is proposed.

Your main fuse rating and incoming supply matter too. Some properties need a load-management device so the charger throttles when the house is drawing heavily, rather than an expensive supply upgrade.

And the unit itself. Chargers vary in price by brand, app features, and whether they are tethered or untethered.

Tethered means the cable is permanently attached to the charger. It is more convenient day to day — no fetching a cable from the boot — and it is the popular choice.

Untethered means a socket on the wall, and you plug in your own cable. It costs slightly less, keeps the wall unit tidier, and future-proofs better: if you change to a car with a different connector, or want a longer cable, you swap the cable rather than the charger.

Cable length on a tethered unit is worth thinking about before ordering. Five metres suits a car parked close; seven or more if the charge port is on the far side or you park further out. Retrofitting a longer cable usually is not possible.

Almost all modern home charging in the UK is 7kW single phase, which typically adds roughly 25–30 miles of range per hour. Faster 22kW charging needs a three-phase supply, which most homes do not have and which is expensive to install.

Home charge point grants have narrowed considerably over the years. The broad domestic grant closed, and support has been targeted at people without private off-street parking, and at flat owners and renters. Eligibility and the schemes themselves change, so check the current position on GOV.UK rather than relying on an installer's summary.

Installation is notifiable electrical work, so it needs an installer who can self-certify through a competent person scheme, or notification to building control. Ask which applies and confirm you will receive a certificate.

If you rent, or live in a flat or a leasehold property, you will usually need the freeholder's or landlord's permission before installation — and if the parking is communal, that conversation is the long pole in the job, not the electrics.

Smart charging requirements apply to new home chargepoints sold in Great Britain, which is why current units come with scheduling and data functions as standard rather than as premium features.

Site the charger as close to the consumer unit as your parking allows. Cable run is the most controllable cost in the whole job.

Get the survey done properly. Most reputable installers do a remote or on-site survey before quoting, and a firm price after survey beats a headline price that changes on the day.

Get more than one opinion if a consumer unit upgrade is proposed. It is sometimes genuinely necessary and sometimes not, and the difference is several hundred pounds.

Ask about load management rather than a supply upgrade if capacity is the issue — it is usually far cheaper.

And check the current grant position yourself on GOV.UK before assuming you do or do not qualify.
