Installing an EV Charging Point at Home: Permitted Development Rules and Grid Connection

Why Home Charging Matters

Approximately 80% of EV charging in the UK takes place at home, according to the Society of Motor Manufacturers and Traders. Charging overnight on a dedicated home charger using a smart tariff (such as Octopus Go or OVO's EV Everywhere tariff) typically costs between 5p and 10p per kWh, compared to 60–80p per kWh at a rapid public charger. For a vehicle with a 60kWh battery, the difference is roughly £3 versus £36–£48 for a full charge.

A properly installed home wallbox (7kW AC) can charge a typical EV from near-empty to full in 6–10 hours — ideal for overnight charging.

Planning Permission: The Permitted Development Position

In most cases, installing a home EV charging point does not require planning permission. Under the Town and Country Planning (General Permitted Development) (England) Order 2015, Schedule 2, Part 2, Class D, the installation of an EV charging point on a house is permitted development, provided:

• The charging unit does not exceed 0.2 cubic metres in size
• It is not installed within 2 metres of the public highway
• The property is not a listed building
• The property is not within a World Heritage Site, National Park, or AONB (or if it is, specific conditions apply)

For flats in apartment buildings, permitted development rights typically do not apply to individual units, and managing agent or freeholder consent is usually required. The EV chargepoint installation process for leasehold flats can be significantly more complex — see below.

Conservation areas do not automatically remove the right to install an EV charger, but the unit must not be installed on a wall facing the highway.

Smart Charger Requirement (Mandatory Since 2022)

Since 30 June 2022, all new EV charge points installed in domestic settings in England must be "smart" chargers under the Electric Vehicles (Smart Charge Points) Regulations 2021. A smart charger:

• Can receive and respond to signals from the electricity system
• Defaults to off-peak charging
• Can be remotely monitored and controlled
• Complies with cybersecurity requirements

Non-smart "dumb" chargers cannot legally be installed as new installations in domestic properties in England. In practice, all modern wallboxes from reputable manufacturers (Ohme, Easee, Andersen, Hypervolt, Zappi, Myenergi) meet this requirement.

Installation Cost and What It Involves

A standard home EV charger installation (7kW, single-phase) costs approximately £800–£1,200 installed, including the charger unit and labour, for a straightforward installation at a house with an existing suitable consumer unit.

Additional costs may arise if:

• The consumer unit needs upgrading to accommodate the additional load
• The cable run from the consumer unit to the charging point is long or requires complex routing
• A new meter or tails upgrade is required
• A three-phase supply is needed for higher-power charging (uncommon in residential contexts)

The EVHS Grant (EV Homecharge Scheme)

The government's original Electric Vehicle Homecharge Scheme (EVHS) for homeowners was closed to new applications for most users in April 2022. The current grant landscape (2026):

• **Renters and flat owners:** The EVHS remains open for flat-dwelling EV owners and renters (£350 towards installation costs)
• **Social housing:** A separate scheme covers social housing residents
• **Workplace charging:** The Workplace Charging Scheme (WCS) provides support for businesses

House-owning EV drivers are no longer eligible for a domestic charging grant. The £350 EVHS grant is available only to those meeting the above criteria.

EV Chargers in Leasehold Flats

Installing an EV charger in a leasehold flat — particularly in a multi-storey block — is considerably more complex than in a house. Issues include:

• **Freeholder/managing agent consent:** Usually required under the lease, which may require a formal licence to alter
• **Electricity supply:** Individual flats may not have a suitable individual supply for a 7kW charger; a shared infrastructure approach may be needed
• **Common areas:** Installing a charger in a car park or garage that forms part of the common parts requires freeholder consent and potentially a new electricity supply from the building's communal supply
• **Cost sharing:** Multiple residents installing chargers in the same car park requires a load management system

The Leasehold Reform (Ground Rent) Act 2022 and proposed further leasehold reforms do not directly address EV charging. Specialist electrical contractors experienced in multi-occupancy EV infrastructure can advise on practical solutions.

Grid Connection: When Upgrade Is Needed

Most UK homes operate on a single-phase 100A supply, which supports a 7kW EV charger comfortably. However, if other high-power loads (electric heating, hot tub, large heat pump) are operating simultaneously, a load management device may be needed to prevent overloading the supply.

Properties in rural areas or older housing stock may have lower-rated supplies. If your meter tails or DNO (Distribution Network Operator) connection is rated below the required capacity, a supply upgrade application through your DNO may be needed. DNO upgrades can take weeks to months and may incur costs of £500–£2,000+.
