EV Charger Installation Cambridge: Costs, Grants, and Conservation Areas 2026

Typical Cambridge Installation Costs (2026)

• Simple installation (modern detached/semi, garage or driveway) — £850 to £1,050. Short cable run, spare consumer unit way, standard earth rod. Common for north Cambridge new builds in Eddington, Northstowe, and Cambourne.
• Standard installation (terrace or Victorian semi) — £1,000 to £1,200. Cable run of 8 to 15 metres, PME earth rod required, possible MCB addition to the consumer unit. Typical for terraces in Romsey Town, Mill Road, and Coleridge areas.
• Complex installation (listed building, conservation area, long run) — £1,200 to £1,600+. Internal cable routing required to avoid visible external works, possible consumer unit upgrade, specialist fixings. Conservation areas and listed properties in the city centre and Newnham areas.
• 22kW three-phase charger — £1,200 to £2,000 installed. Requires a three-phase supply and G99 approval from UKPN. Suitable for technology sector employees with high-mileage requirements and an existing three-phase supply.

• OZEV EV chargepoint grant — up to £350 for flat owners and tenants who own or lease an eligible plug-in vehicle. Cambridge's large student and research community means many city residents in rented accommodation are eligible. Applied for by your OZEV-approved installer.
• Workplace Charging Scheme — Cambridge's many tech companies, biotech firms, and research institutions can claim up to £350 per socket (maximum 40 sockets) for workplace EV charger installation. Requires an OZEV-approved commercial installer.
• Greater Cambridge EV strategy — the Greater Cambridge Partnership and Cambridgeshire and Peterborough Combined Authority support EV charging infrastructure expansion, including on-street charging rollout in residential areas without off-street parking. Check Cambridge City Council's transport pages for current schemes.

• Dedicated final circuit (Regulation 722.533.101) — a dedicated 32A circuit from the consumer unit. Older Cambridge consumer units in Victorian properties may not have a spare way, requiring a board upgrade or separate enclosure.
• RCD protection (Regulation 722.531.101) — appropriate RCD protection covering the EV circuit. Modern smart chargers typically include integrated DC fault protection, satisfying the Type B RCD or Type A with 6mA DC RDC-DD requirement.
• Smart charger compliance — the Electric Vehicles (Smart Charge Points) Regulations 2021 requires all new home EV chargers to support smart scheduling, randomised delay, and demand side response. All chargers on the OZEV approved charger list are compliant.
• Cable sizing — use Elec-Mate's cable sizing calculator to verify voltage drop is within the 5% limit for the actual cable run length. 6mm² is adequate for most Cambridge installations; 10mm² may be needed for runs exceeding 15 metres or where 10mm² is needed for derating.

• G98 notification (7kW single-phase) — submit online via the UKPN portal. This is a notification, not an application — the installer proceeds with connection and notifies concurrently for standard domestic 7kW installations. No prior approval is required.
• G99 application (22kW three-phase) — prior approval required from UKPN before installation. Allow 4 to 10 weeks. Required for three-phase chargers and multiple charger commercial premises. Cambridge's tech employers increasingly need G99 for workplace charging hubs.
• Installer responsibility — the electrician handles UKPN notification. Confirm this is included in the quoted price. Failure to notify UKPN can result in the charger being required to be disconnected until notification is properly submitted.

• Conservation areas across Cambridge — Cambridge City Council designates extensive conservation areas covering much of the historic centre, the Backs, Newnham, Chesterton, and parts of Romsey Town. Installations on front elevations of properties in conservation areas may require planning permission, particularly where the charger or cable trunking is prominently visible from the street.
• Listed buildings — Listed Building Consent from Cambridge City Council is required for any works that alter the character of a listed building, including drilling through external walls or mounting equipment on listed elevations. An experienced Cambridge electrician will advise on the consent process and help design an installation that minimises impact.
• Internal cable routing — for conservation area and listed building properties, running the cable internally (through floors, walls, and ceilings) and exiting at a discreet rear or side elevation avoids the need for planning permission in most cases. This increases installation time and cost but ensures compliance. Always confirm the specific planning requirements for your property before booking an installer.
• Village properties in the Cambridge green belt — surrounding villages including Grantchester, Trumpington, Cherry Hinton, and Histon may have their own conservation designations. Check with South Cambridgeshire District Council for village-specific planning requirements before installation.
