How to install an EV charger at home

People search for “how to install an EV charger” hoping for a weekend job. This guide is honest about why it is not one, and useful about everything around the electrical work that you can do yourself.

Can you install an EV charger yourself?

Not in any way we would recommend. The rules and the practicalities both point the same way.

The rules. In England the installation of a new circuit is notifiable under the Building Regulations (reg 12(6A), Part P). An electrician on a competent person scheme self-certifies the job. Anyone else must notify building control before work begins, so a householder is not forbidden from doing it, but the work then has to be checked and meet BS 7671. Wales has a similar, wider regime. Scotland uses building standards, and for work to a house you usually need no warrant but must still comply. Northern Ireland has no equivalent of Part P, though Electrical Safety First still says to use a registered, competent installer.

The practicalities. BS 7671 Section 722 sets out a dedicated circuit, a 30mA RCD with DC fault protection, open-PEN or earth electrode protection on a PME supply, and weather and impact ratings for outdoor equipment. Getting any of it wrong is a shock or fire risk, and the testing needs instruments most households do not own. The grant also needs an OZEV-authorised installer, and warranties can depend on who fits the charger: Hypervolt’s three-year warranty applies from installation by a qualified electrician.

What you can prepare yourself

Most delays and surprise costs come from things a householder can sort out in advance.

Choose the spot. Pick the nearest suitable brick or rendered wall to the consumer unit that your car can reach. Standard installs assume a short cable run through no more than one wall, and every provider allows only so much cable: from 5 metres to 15 metres. Pod’s standard install needs the consumer unit on the ground floor.

Check the signal. Smart chargers need a connection. Hypervolt suggests a Wi-Fi booster if the signal at the charger is weak (below -60dBm), whereas Ohme’s chargers have their own 4G SIM. Check your phone at the wall.

Take the survey photos. The installer will want the meter and the main fuse (cut-out), the consumer unit, the spot where the charger will go and the route between them. Follow the form’s instructions and do not open anything that is not meant to be opened.

Sort permissions. If you rent or own a flat, get your landlord’s or freeholder’s written permission; there is no right to charge. In England a driveway charger normally needs no planning application (see our planning guide). Tell your home insurer.

Check grants before you buy. If you rent, own a flat with private parking or only park on the street, apply for the OZEV grant and wait for its eligibility notice before anything is installed. Owner-occupiers of a house with a driveway are not eligible.

Choose the charger and tariff. You are choosing between a tethered and an untethered unit (see our tethered vs untethered guide) and a smart tariff it will work with. Our best home EV chargers roundup compares them.

What the installer does, step by step

1. 1

   Survey

   Remote from your photos, or in person. The installer checks the supply, earthing, consumer unit and cable route, and decides whether the network operator must be asked first.

2. 2

   Quote and booking

   A written quote with the included cable length, VAT, and any extras such as a consumer unit or earth electrode.

3. 3

   Prepare the consumer unit

   The supply is isolated. A dedicated way is found in the board, or the board is changed if it cannot take one.

4. 4

   Mount the charger

   Fixed to a brick or rendered wall at a suitable height, with the weather and impact ratings BS 7671 asks for outdoors.

5. 5

   Run the cable

   A dedicated cable from the consumer unit to the charger, clipped or in trunking, usually through one hole in the wall. OVO's standard install specifies up to 10 metres of 6mm cable. A hole through a wall to an attached garage is fire-stopped.

6. 6

   Fit protection and earthing

   An RCD or RCBO on the new circuit, and open-PEN protection or an earth electrode on a PME supply.

7. 7

   Test and commission

   Inspection and testing to BS 7671, then the charger is connected to your Wi-Fi or mobile network and the app.

8. 8

   Notify and certify

   The installer completes the Electrical Installation Certificate, tells the network operator and notifies building control through their scheme.

The visit as a whole takes two to four hours. Hypervolt’s standard installation, as EVC Experts describes it, runs the cable from the consumer unit out through a single hole and along the external brickwork at low level, with up to 10 metres of surface-cleated cable.

RCBOs, consumer units and earthing

BS 7671 Section 722 asks for each charging point to be protected by a 30mA RCD (Type A, F or B) that also deals with smooth DC leakage. The charger can supply the DC detection itself, and Amendment 4 (2026) lists a residual direct current protective device as an alternative to an RCD. In the consumer unit, the usual solution is a dedicated RCBO, which combines the RCD and overcurrent protection in one device.

What the charger builds in decides what the board must provide, and makers differ. The Hypervolt Home 3 Pro has only 6mA DC detection, so it needs an external Type A RCD or RCBO of 30mA or less. Ohme says an upstream RCD of at least Type A 30mA is usually required and recommends a 40A Type B MCB. myenergi’s UK FAQ also asks for a separate upstream 30mA Type A RCD for the zappi. If the board has no spare way or cannot take an RCBO, a consumer unit replacement adds to the bill; the cost guide prices it.

Most UK homes have PME earthing, so the charger or a separate device must protect against an open-PEN fault, or the installer fits an earth electrode. Our PEN fault and earthing guide covers it.

Telling the network operator, and the paperwork

Every charger must be reported to the electricity network operator. For a normal home your installer connects first and notifies within 28 days through ENA Connect Direct; they must apply first for a looped supply, a new demand of 60A to 100A, an unknown cut-out, or a heat pump fitted at the same time. The wider process, with fuse upgrades and unlooping, is in our installation guide.

You should end up with an Electrical Installation Certificate, a Building Regulations compliance certificate (within 30 days) and proof the network operator was notified. If you are doing any of this under a grant, the installer also claims it and deducts it from your invoice.
