EV charger installation in Broxbourne and East Hertfordshire

What does installing a home EV charger involve?

A wall-mounted charger, sometimes called a chargepoint or wallbox, is connected to your fuse board on its own dedicated circuit. The electrician checks that your supply and fuse board can take the extra load, plans a route for the cable, mounts the charger near where you park and tests the installation. Adding a new circuit in a home in England is notifiable under Part P of the building regulations, so you should receive an Electrical Installation Certificate and confirmation that the work has been notified.

Many electricians ask for photos of your fuse board, electricity meter and the spot where you want the charger before they visit, so they can see what the job is likely to involve.

Can my property have a charger?

Most homes with off-street parking, such as a driveway or garage, can have one. Things that affect the installation include:

• whether you can park next to the property, since a cable trailing across a pavement is not a safe option
• the distance between your fuse board and the charger position
• the size of your main fuse and how much electricity the property already uses at busy times
• the age and condition of your fuse board and wiring
• the earthing arrangement for your supply
• whether you own or rent, or live in a flat, where you will need permission from the landlord or freeholder

Why does earthing matter for EV chargers?

Many UK homes have a PME earthing arrangement, where the earth is shared with the network's neutral conductor. If that combined conductor breaks, known as an open-PEN fault, metal parts connected to the earth could become live. A car parked outside is a particular concern because someone can touch the car and the ground at the same time. The wiring regulations therefore require protection against this. In practice, that usually means a charger with built-in open-PEN detection, or a separate earth rod for the charger. The electrician will decide which approach suits your property.

Will the network operator need to know?

Often, yes. A charger adds load to your supply, and the installer is expected to notify the local distribution network operator (DNO). In some cases, for example where the main fuse is small or a heat pump is already fitted, the DNO may need to approve the installation first or upgrade the supply. The electrician normally deals with this, but it can affect the timing.

Do I need a smart charger, and is there a grant?

Since 2022, regulations have required most new chargers sold for home and workplace use in Great Britain to have smart functions, such as scheduled charging and the ability to respond to signals from the grid. If you are on a suitable tariff, this can let you charge when electricity is cheaper.

Government grants for chargers are now limited to certain groups, such as people who rent or own a flat, landlords and businesses. Schemes and eligibility change, so check gov.uk for current details before you rely on a grant.

What about chargers for businesses?

Businesses can install charging for staff, visitors or fleet vehicles. Larger sites may need several charge points, load management to share the available supply, and sometimes a supply upgrade. If you are enquiring for a business, say how many vehicles you expect to charge and where they park.

What should I tell the electrician?

• the make and model of your car, and any charger you have in mind
• where you park and where you would like the charger mounted
• where your fuse board and meter are, with photos if possible
• whether you have a heat pump, solar panels or a home battery
• whether you own the property, rent it or live in a flat

What happens after I send an enquiry?

With your agreement, we pass your enquiry to one local electrician covering your postcode, never to a list of installers. They contact you to talk through the installation, may ask for photos or arrange a survey, and give you a quote directly. You decide whether to proceed.

There is no charge for sending an enquiry and no obligation. We are an independent enquiry service, not an installer, and the electrician may pay us a fee for the introduction.
