The complete guide to home EV charger installation in the UK

1. Before you start: the one question that matters most

Before charger models, grants, and installer quotes, there is one question that determines almost everything else: do you have off-street parking?

A dedicated off-street parking space — a driveway, garage, or private car park — is what makes a home charger viable. It is where the charge point mounts, it is the address your installer surveys, and it is a eligibility requirement for the government grant. If you have one, the rest of this guide applies to you in full.

If you do not — if you park on the street, or in a shared car park with no dedicated bay — there are still options: lamp-post chargers, pavement cable gullies, and shared-ownership schemes through your local authority. The solutions are more complex, but they exist.

2. Which charger should you get?

Almost all home EV chargers in the UK are 7.4 kW units — this is the maximum output a standard single-phase domestic supply can deliver. At 7.4 kW, a typical 60–75 kWh battery (covering most modern EVs) charges from near-empty to full overnight, in roughly 8–10 hours. This suits the vast majority of drivers.

Beyond raw power, the main differentiators between brands are:

• Solar integration — the Zappi by myenergi can intelligently divert excess solar power to your car before exporting to the grid
• Smart scheduling — all major brands now offer overnight off-peak scheduling via an app (important if you are on an EV-specific electricity tariff such as Octopus Go or OVO Drive)
• Tethered vs untethered — a tethered charger has the cable permanently attached; untethered units use a socket you plug your own cable into. Tethered is more convenient; untethered is tidier and more flexible if you change vehicles
• App quality and data reporting — varies considerably between brands

If your home already has solar panels or you plan to install them, the Zappi is usually the standout choice. For most other drivers, Hypervolt, Ohme, and Pod Point all deliver reliable smart charging at competitive prices.

3. What does installation cost?

Before the government grant, a typical domestic EV charger installation costs between £800 and £1,200 — including the charger hardware and labour. This is for a standard installation: charger mounted on an external wall, cable routed neatly to the consumer unit, Building Regulations notification included.

Costs vary by region — London and the South East typically run 15–20% higher than the Midlands and North. The condition of your existing consumer unit matters too: an older fuse board may need upgrading before a dedicated charger circuit can be added.

4. Can you get a grant?

Yes — if you meet the eligibility criteria. The Electric Vehicle Homecharge Scheme (EVHS) covers up to £500 towards the cost of a home charger. Your OZEV-approved installer claims the grant directly on your behalf and deducts it from your invoice. You do not apply separately.

To be eligible:

• Your vehicle must be on the OZEV eligible vehicle list
• Your property must have dedicated off-street parking
• You must be the owner of the property, or have the landlord's permission
• Your installer must be OZEV-approved

Flat owners and renters in multi-unit buildings are covered by the separate Flat Owner and EV Infrastructure (FOEI) grant — also up to £500 per household, with slightly different eligibility rules.

5. What happens on installation day?

A well-run EV charger installation follows a predictable sequence. Knowing what to expect helps you prepare — and helps you spot if something is being skipped.

1. 1. Pre-installation survey

   Before the installation date, your installer should survey the job — either in person or via photos and your answers to a few questions. They will assess your consumer unit, identify the best cable route, check for any DNO constraints, and confirm the grant paperwork if applicable. Do not book with an installer who skips this step.

2. 2. Grant paperwork

   If you are claiming the EVHS grant, your installer submits the application to OZEV on your behalf before the installation. This typically happens in the days before the job.

3. 3. Installation (2–4 hours)

   On the day: the installer runs a new dedicated circuit from your consumer unit to the charger position, mounts the unit on the wall, connects and tests it, and walks you through the app setup. A standard job takes two to four hours.

4. 4. Building Regulations notification

   Installing a new electrical circuit is notifiable work under Part P of the Building Regulations. Your NICEIC or NAPIT-registered installer handles the notification automatically. You do not need to do anything separately.

5. 5. Certificates and documentation

   You should receive an Electrical Installation Certificate (EIC) or Minor Electrical Installation Works Certificate, confirmation of the Part P notification, the charger warranty documentation, and your grant claim confirmation if applicable.

6. How to choose the right installer

Three accreditations to verify before you book:

Beyond accreditations: always get at least two quotes, check reviews from recent customers, and confirm the installer does a pre-installation survey before booking. An installer who quotes without assessing the job is one to avoid.

7. Special circumstances

Most EV charger installations are straightforward. Some are not. Here is a quick guide to the most common complications and where to get the full picture.

8. After installation: what you should receive

A correctly completed installation should result in the following documentation. Chase your installer if any of these are missing — they are not optional extras.

• ✓
  Electrical Installation Certificate (EIC)Or a Minor Electrical Installation Works Certificate, covering the new dedicated circuit. Issued by the installing electrician.
• ✓
  Building Regulations Part P notificationConfirmation that the new circuit has been notified to Building Control. Your NICEIC or NAPIT installer handles this; you should receive confirmation.
• ✓
  Charger manufacturer warrantyUsually 3 years for the hardware. Some brands offer extended warranties; check at purchase.
• ✓
  EVHS grant confirmationIf you claimed the grant, your installer should provide confirmation that the claim has been submitted and what amount was deducted.
• ✓
  App setup and usage walkthroughYour installer should walk you through the manufacturer app, show you how to set a charging schedule, and confirm your charger is communicating correctly.
