EV Charger Advice & Installation Support

Installing a home EV charger involves more than picking a unit on price. EvoHome Improvements helps homeowners across Hampshire and the South think through charger speed (3.6kW vs 7kW vs 22kW where supply allows), tethered vs untethered, smart features, solar/battery integration, off-street parking, cable routing, consumer unit and earthing arrangement, and DNO notification requirements.

We also help homeowners understand any current OZEV grant routes — without guaranteeing eligibility or grant outcomes. EvoHome Improvements advises and coordinates; independent vetted OZEV-approved electricians carry out the physical installation and certification. We do not quote fixed prices, exact timescales or guaranteed charging speeds without a proper site survey.

Home EV charging is the most convenient and cost-effective way to charge an electric vehicle. With the UK banning new petrol and diesel car sales from 2035, installing a home charger is an investment in the future that adds genuine value to your property.\n\n## Charging Speeds Explained\n\nA 7kW home charger fully charges a typical 60kWh battery in 8–9 hours — perfect for overnight charging.

This covers 200+ miles of range. For most UK drivers averaging 20–30 miles daily, even a few hours of charging provides a week's driving. 22kW three-phase chargers are available for those needing faster charging.\n\n## Cost Savings\n\nCharging at home on an EV-specific tariff costs approximately 7–10p per kWh (off-peak), compared to 30–50p at public rapid chargers.

This translates to approximately 2–3p per mile, compared to 12–15p per mile for petrol. Annual fuel savings of £1,000–£2,000 are typical.\n\n## Installation Requirements\n\nEV chargers require a dedicated circuit from the consumer unit, typically using 6mm² or 10mm² cable depending on distance. The installation must comply with BS 7671 (IET Wiring Regulations) and include appropriate protection.

A registered electrician must certify the installation.\n\n## Smart Charging\n\nAll OZEV grant-eligible chargers must be 'smart' — capable of scheduling charging to off-peak hours, responding to grid demand signals, and integrating with solar generation. This maximises savings and supports grid stability as EV adoption grows.
