Installing a dedicated home EV charger is the single most cost-effective upgrade for any electric vehicle owner. Charging from a standard 13 A socket (a “granny charger”) delivers around 2.3 kW, a full charge from empty on a 77 kWh battery takes over 30 hours. A dedicated 7 kW wall box cuts that to around 11 hours, and a 22 kW three-phase unit (where the supply allows) to just over 3 hours.

For most homeowners with a standard single-phase 100 A supply, a 7.4 kW smart charger is the right choice: fast enough for overnight charging of any current EV, compatible with all standard domestic supplies, and qualifies for smart-tariff integration that can dramatically cut running costs.

Home EV Charger Costs (2026)

ItemTypical Cost
7 kW smart charger unit (supply only)£350–£700
Standard installation (within 10 m of consumer unit, existing cable route)£400–£600
Long cable run (10–25 m, new trunking or armoured cable)£600–£900
Three-phase 22 kW charger (if supply available)£900–£1,800 installed
Consumer unit upgrade (if required)£500–£1,200 extra
Typical total for a straightforward 7 kW install£750–£1,200

Prices vary by region; London and South East labour rates typically run 15–25% above the national average. Always get at least two quotes from OZEV-approved installers.

Government Grants in 2026

EV Chargepoint Grant (Flats and Renters)

The Electric Vehicle Homecharge Scheme (EVHS) for homeowners with off-street parking closed to new applications on 1 April 2022.1 It has not been replaced with an equivalent grant for homeowners.

However, the EV Chargepoint Grant remains open for:

  • People living in flats (owner-occupiers or renters in purpose-built or converted flats)
  • Renters in houses (with landlord permission)
  • Landlords of residential properties (separate commercial-rate grant)

The grant covers up to £500 (or 75% of the cost of buying and installing the socket, whichever is lower) per chargepoint for eligible flat-dwellers and renters.2 Applications go through your OZEV-approved installer. The grant cannot be claimed if you have previously received an EVHS grant for the same property.3

Workplace and Public Grants

For businesses and public locations, the Workplace Charging Scheme (WCS) provides up to £350 per socket (maximum 40 sockets across all sites).4 Not applicable to domestic installations.

Choosing the Right Charger

Tethered vs Untethered

  • Tethered chargers have a cable permanently attached. Convenient, no cable to store, but if the cable is damaged you replace the whole unit.
  • Untethered (socketed) chargers have a Type 2 socket. You use your own cable, which is more flexible for multi-EV households but means managing the cable.

Smart vs Dumb

All chargers installed under the EV Chargepoint Grant must be smart chargers that meet the UK’s EV smart charging requirements, set by the Electric Vehicles (Smart Charge Points) Regulations 2021 and in force since 30 June 2022. Smart chargers:5

  • Default to pre-set off-peak charging hours, with a randomised delay of up to 600 seconds so that chargers do not all start at once
  • Can be scheduled and monitored via an app
  • Are compatible with smart energy tariffs (Octopus Intelligent, OVO Charge Anytime, etc.)

Smart tariffs for EV charging typically offer rates of 7–12 p/kWh overnight, versus the standard unit rate of around 24–28 p/kWh.6 For a typical EV doing 10,000 miles/year, this can save £400–£700 annually.

Output Rating

Supply TypeMax Charger OutputFull Charge Time (77 kWh)
13 A socket2.3 kW~33 hours
7.4 kW single-phase7.4 kW~10–11 hours
22 kW three-phase22 kW~3.5 hours

Most UK homes have single-phase 230 V supplies. Three-phase is common in newer large homes and rural properties on agricultural supplies, but you must verify with your Distribution Network Operator (DNO) before assuming availability.

Installation Rules and Permitted Development

Permitted Development

In England, installing an EV charger on a house (including the cable route and wall box) is generally permitted development under Class D of Part 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015, provided:

  • The wall-mounted outlet is within an area lawfully used for off-street parking
  • The outlet and its casing are no greater than 0.2 m³
  • It is not within a site designated as a scheduled monument
  • It is not within the curtilage of a listed building

Class D also imposes a condition: once the outlet is no longer needed for charging it must be removed and the wall reinstated as far as reasonably practicable. The old restriction on an outlet facing a highway was removed on 29 May 2025.7

Listed buildings and properties in Conservation Areas may need listed building consent or planning permission. Always check with your local planning authority if in any doubt.

Building Regulations

Installing an EV charger on its own new circuit is notifiable under Part P (Electrical Safety) of the Building Regulations in England and Wales, and under the equivalent Scottish Building Standards.8 This means the work must either be carried out by a registered competent person who self-certifies it, or be notified to your local building control before it starts. OZEV-approved installers handle this automatically; if you use a non-approved electrician, you will need to apply for a building regulations completion certificate yourself.

The installation must also comply with BS 7671, the IET Wiring Regulations. Each charging point must be protected by its own RCD of at least Type A with a residual operating current not exceeding 30 mA, and on most units that device sits inside the charging equipment itself.9

Consumer Unit and Meter

A 7 kW charger draws around 32 A. If your consumer unit does not have a free 32 A MCB slot, or if your meter tails are already heavily loaded, your installer may recommend a consumer unit upgrade or a dedicated supply from the meter tails (a “henley block” arrangement). Most modern homes (post-2000) will accommodate a 32 A circuit without issues. Pre-1980s homes with 60 A main fuses may need a DNO supply upgrade, contact your DNO for a quote (typically free if upgrading to 100 A).

What to Check Before Booking

  • Do you have a private off-street parking space? (Required for home installation)
  • Is your consumer unit modern enough to accept a 32 A MCB? Ask your installer to assess.
  • Do you need a cable run longer than 10 m? Get this specified in the quote.
  • Are you eligible for the EV Chargepoint Grant? Check at gov.uk/apply-for-ev-chargepoint-grant.
  • Does your energy tariff offer smart EV charging rates? Worth switching before installation.

Finding an Installer

Only use an OZEV-approved installer to ensure compliance and grant eligibility. Search the approved installer list at gov.uk. Installers should be registered with NICEIC, NAPIT, or the ECA, and hold the IET’s EV Charging Installations qualification (2913.12) or equivalent. Ask for a written quote including the cable route, protection devices, and make/model of charger.

  5. 5technicalvery strongThe National Archives (legislation.gov.uk), legislation.RN-3G6RWDSI 2021/1467, in force 30 June 2022, extending to England and Wales and Scotland. Regulation 10 requires a relevant charge point to incorporate pre-set default charging hours outside peak hours, with the owner able to accept, remove or change them on first use and at any time afterwards; peak hours are defined in regulation 10(4) as 8am to 11am and 4pm to 10pm on weekdays. The requirement is disapplied where the charge point is sold with a demand side response (DSR) agreement and configured to comply with it. Regulation 11 requires the charge point to operate at each relevant time with a randomised delay of up to 600 seconds, determined to the nearest second, which the owner can cancel; it must also be capable of a randomised delay of up to 1800 seconds, remotely adjustable over a communications network. A relevant time is the point at which electricity would start flowing or the rate of flow would change. Other regulations cover smart functionality (5), supplier interoperability (6), failsafe on loss of communications (7), safety (8), measuring systems (9) and security (Schedule 1).
  6. 6technicalvery strongOfgem.RN-YYE8U2The live source for any running-cost sum in a heating note. For 1 October to 31 December 2026 the direct debit cap is 26.32p per kWh for electricity with a 54.83p daily standing charge, and 7.97p per kWh for gas with a 29.68p daily standing charge, giving a typical annual dual fuel bill of £1,723, a 4% rise on the previous period. Ofgem states these are the average unit rate and standing charge for direct debit customers in England, Scotland and Wales; gas prices include 5% VAT while electricity carried no VAT in this period.

  7. 7technicalvery strongThe National Archives (legislation.gov.uk), UK Statutory Instrument 2015/596, legislation.RN-38KO9RClass A of Part 2 is the fence, gate and wall rule cited whenever a note discusses fence height. It permits the erection, construction, maintenance, improvement or alteration of a gate, fence, wall or other means of enclosure up to 1 metre above ground level where adjacent to a highway used by vehicular traffic (or the footpath of such a highway), and up to 2 metres above ground level elsewhere. Where an existing enclosure is maintained, improved or altered, the resulting height must not exceed its former height or the applicable limit, whichever is the greater. Class A is withdrawn within the curtilage of a listed building, or for a gate, fence, wall or other means of enclosure surrounding a listed building.

  8. 8technicalvery strongMinistry of Housing, Communities and Local Government.RN-JYJ3I5The document that decides what electrical work a homeowner may legally do themselves, and the exact list of notifiable jobs. Regulation 12(6A), reproduced at paragraph 2.5, makes only three things notifiable: the installation of a new circuit, the replacement of a consumer unit, and any addition or alteration to existing circuits in a special location. Regulation 12(9) defines special location as, in a room containing a bath or shower, the zone extending vertically from finished floor level to 2.25 metres (or the shower head position if higher) and horizontally 600mm from the edge of the bath tub or shower tray. Paragraph 2.7 states that all other electrical installation work is not notifiable, namely additions and alterations to existing installations outside special locations, and replacements, repairs and maintenance anywhere. Paragraph 2.8 gives worked examples: a built-in cooker is not notifiable unless a new cooker circuit is needed, and connecting an electric gate or garage door to an existing isolator is not notifiable but running a new circuit from the consumer unit to that isolator is. Paragraph 2.2 confirms Part P reaches outdoor work including fixed garden lighting, pond pumps and outbuildings such as sheds, detached garages and domestic greenhouses. Notifiable work must be certified by self-certification by a registered competent person, third-party certification, or a building control body (paragraph 3.1), with the compliance certificate issued within 30 days (paragraph 3.4). Note that Approved Document P is a source of guidance rather than a ban: non-notifiable work still has to comply with BS 7671.
  9. 9technicalstrongInstitution of Engineering and Technology, guidance.RN-GZ3QEKIET FAQ page on Section 722 of BS 7671. States that Regulation 722.531.2.101 requires the charging point to be RCD protected by its own RCD of at least a Type A, having a residual operating current not exceeding 30 mA, and that the requirement attaches to the charging point rather than necessarily the whole final circuit. Notes that in practice the RCD will usually be installed within the charging equipment and advises verifying this with the equipment supplier. Refers on to the IET Code of Practice for Electric Vehicle Charging Equipment Installation. Useful for correcting notes that claim a Type B or Type F RCD is required for domestic EV chargers.
