If you’re switching to an electric car, installing a home EV charger is often the most convenient and cost‑effective way to charge – but many people aren’t sure what it costs or how it fits with the rest of their home‑energy setup.
This guide explains:
- Typical EV home‑charger installation costs.
- How grants and tariffs can reduce the bill.
- How EV charging fits into a whole‑home energy and EPC strategy.
EV charger costs (overview)
Typical all‑in costs for a standard 7 kW home charger are often in the range of:
- £800–£1,500+, depending on brand, features and installation complexity.
You’ll usually pay more if:
- The charger is far from your consumer unit.
- Your electrical system needs upgrades (e.g. consumer‑unit changes or supply checks).
- You want a smarter unit with load balancing, solar integration or app‑based control.
Types of home EV charger
Most UK home chargers are:
- 7 kW “fast” chargers – common for overnight home charging.
- Either tethered (with a fixed cable) or untethered (socket only).
Key choices:
- Tethered vs untethered: tethered is more convenient; untethered looks tidier and works with different connector types.
- Smart features: many modern chargers support scheduling, integration with EV tariffs and solar‑aware charging.
Your installer will also consider:
- The rating of your incoming supply.
- Whether load management is needed to avoid overloading your system when other appliances are in use.
Grants and tariffs
Grant schemes and tariffs change regularly, but key themes include:
- Support for home EV chargers in certain circumstances (for example, for flats or rented properties under some schemes).
- Off‑peak EV tariffs that make overnight charging significantly cheaper.

EPC and whole‑home energy
An EV charger itself doesn’t typically transform your EPC rating, but:
- Installing solar PV (see Solar Panels and EPC Rating) alongside a charger can make daytime charging cheaper and greener.
- Improving your home’s fabric and heating (see 27 Ways to Improve Your EPC Rating) helps ensure your overall energy use stays manageable as you electrify transport.

Installation basics and safety
Your installer will:
- Check your supply and consumer unit to confirm it can support a charger.
- Install new cabling and appropriate protection devices.
- Position the charger where it’s easy to reach from your usual parking spot.
- Test the system and provide handover instructions.
Always use a qualified installer and follow manufacturer guidance to keep your system safe and compliant with regulations.
Next steps
- Check your home’s current EPC and recommendations.
- Plan fabric and heating upgrades first, then consider how EV charging and solar fit into your long‑term energy strategy.
- When you’re ready, get a couple of fixed‑price quotes from reputable EV charger installers and compare them on scope, warranty and smart‑feature support.
