EV Charger Installation London: Costs, DNO, and Grants 2026

Typical London Costs (7kW Single-Phase, 2026)

• Simple installation (detached/semi, short cable run) — £900 to £1,300. Charger mounted near consumer unit, existing board has spare capacity. Typical for newer-build houses in outer London boroughs.
• Standard installation (terraced house, medium cable run) — £1,300 to £1,600. Cable run of 10 to 15 metres through the property, possible board upgrade. The most common London domestic installation.
• Complex installation (long run, board upgrade, earthing work) — £1,600 to £2,200+. Cable run of 15 to 25 metres, consumer unit replacement, earth rod installation, civil works for underground cable routing. Common for Victorian terraces with rear consumer units and front parking.

• Victorian and Edwardian terraces — the consumer unit is often at the rear of the property (under the stairs or in the kitchen), while parking is at the front. This means a cable run of 15 to 25 metres through the house, along walls, through floors, or underground via a front garden trench. Containment and making good add time and materials.
• Flats and converted properties — shared parking, freeholder permission requirements, and communal electrical risers complicate installations. Load management may be needed where multiple flats share a supply. Cable routing through communal areas requires building management approval.
• On-street parking only — many London properties have no off-street parking. On-street EV charging requires a cable channel across the pavement (some boroughs permit this with a cable cover) or reliance on public charging infrastructure. Installation of a charger on the property boundary requires careful consideration of cable protection and public safety.
• Conservation areas and listed buildings — charger mounting on the front elevation may require planning permission. Check with your borough planning department before committing to an installation location. Internal cable routing may be the only option.
• Ageing consumer units — many London properties still have older consumer units without RCD protection. Adding a 32A EV charger circuit often triggers a full consumer unit upgrade to meet current regulations, adding £300 to £800 to the total cost.

• Dedicated circuit (Regulation 722.533.101) — each EV charger requires a dedicated circuit. In London's older consumer units, this often means there is no spare way available, triggering a board upgrade or the addition of a separate enclosure.
• RCD protection (Regulation 722.531.101) — the EV circuit must be protected by an appropriate RCD. Where the charger can produce DC residual currents, a Type B RCD or a Type A RCD with integrated DC fault detection (6mA DC RDC-DD) is required. Most quality charger units include integrated DC protection.
• Earthing (Regulation 722.411.4.1) — earthing arrangements require particular attention. The majority of London properties are on PME supplies, where additional protective measures are needed for outdoor EV charging points. See the PME earthing section below.
• Cable sizing for long runs — the long cable runs common in London terraces require careful cable sizing to account for voltage drop. A 20-metre run in 6mm2 cable for a 32A load is close to the voltage drop limit; 10mm2 may be needed.

• G98 notification (standard domestic) — for single-phase 7kW chargers (up to 32A), submit a G98 notification via the UKPN online portal. This is a notification, not an application — you can proceed with the installation. UKPN processes these automatically.
• G99 application (three-phase/commercial) — for 22kW three-phase chargers or multiple charge points, G99 requires prior approval from UKPN. Allow 4 to 10 weeks for processing. UKPN may conduct a network capacity assessment, particularly in areas with high EV charger density.
• Network capacity — in some London areas with heavy EV charger uptake, UKPN may flag capacity constraints. This is more common in dense residential streets where multiple properties have installed chargers. In rare cases, a supply upgrade may be needed.

• EV chargepoint grant (national) — available to flat owners and tenants only (not homeowners in houses). Covers up to 75% of installation cost, capped at £350 per installation point. Applied for by the OZEV-approved installer.
• Borough on-street charging schemes — multiple London boroughs including Westminster, Lambeth, Hackney, Wandsworth, Brent, and Islington have installed or are expanding lamp-post chargers and dedicated on-street charging bays. These are council-funded and free or low-cost to residents.
• Workplace Charging Scheme — London businesses can claim up to £350 per socket (up to 40 sockets) for workplace EV charger installations. This is a national scheme administered by OZEV.
• Mayor of London EV Infrastructure Strategy — the GLA is investing in rapid charging hubs and supporting borough-level on-street charging rollouts. While this does not directly fund home installations, it improves the overall charging ecosystem for London residents.
