EV Charger Installationin Worcester

What actually decides the job

Start at the cut-out, the sealed fuse where the supply enters the house. Worcester stock runs from 60A in older terraces through 80A to the 100A that newer estates get. A 7.4kW charge point draws 32A continuously. Add a 9.5kW shower and an induction hob and a 60A supply is already committed, so the choice is load curtailment, which lets the charger throttle itself when the rest of the house is busy, or an upgrade you have to ask the network operator for. We read the fuse rating off your cut-out on the survey and tell you which of those you are looking at.

Then earthing. Most houses here are TN-C-S, usually called PME, where the supply neutral doubles as the earth. That is fine indoors and a problem outdoors: if the network's combined neutral-earth conductor fractures somewhere in the street, the metal case of a car on your drive can rise to mains voltage. BS 7671 Section 722 is the part of the wiring regulations written for exactly this. There are two straight answers. Most current charge points detect an open PEN themselves and cut the supply, which is the tidy route. Where the unit cannot, the charger gets its own earth electrode driven outside the influence of the network's, and that is a rod in the ground and a morning's work. Which one applies to you depends on the unit you choose, and it is worth knowing before you buy it.

The cable run is the rest of the money. A charger on the wall behind the consumer unit is a short length of 6mm. A charger at the far end of a detached garage is 10mm, a trench or a clipped run along the fascia, and possibly armoured cable. Volt drop over distance is why the cable gets fatter rather than us guessing. Measure the route before you compare quotes, because a quote that has not asked where the car parks is a quote that will change.

One more that catches people out. Since mid-2022 a charge point sold for a home in Great Britain has to be a smart unit under the Electric Vehicles (Smart Charge Points) Regulations 2021. It has to default to charging off-peak and apply a randomised delay of up to ten minutes, so the street does not all switch on at once. If a listing is cheap because the unit is not smart, that is why.

What the install covers

One visit where possible, and the paperwork in your hand before we drive off.

• Cut-out fuse rating and earthing arrangement confirmed on site
• Dedicated circuit from the board, sized for the real cable run
• Open-PEN protection, or an earth electrode where the unit needs one
• Type A RCD protection with 6mA DC detection, as Section 722 requires
• Load curtailment set up where the supply cannot take the full draw
• Cable clipped, ducted or buried to suit the route, not left slack
• Tested, energised, and your first charge started while we are there
• Electrical Installation Certificate and the notification to Building Control

From survey to first charge

Survey

Cut-out fuse, earthing arrangement, board space, and the route from board to parking space, measured.

Fixed price

In writing, with the cable size and the earthing route named, so you can put it beside another quote and compare like for like.

Install

Usually half a day. Longer if an earth electrode goes in or the run is buried.

Test and hand over

Earth loop, RCD and insulation resistance tested, the app paired, the certificate handed over.

EV charger installation across Worcester and Worcestershire

City terraces with no off-street parking are the one case we will tell you not to bother, and we will say so on the phone rather than after a survey. Everywhere with a drive or a garage is straightforward: Worcester, Droitwich Spa, Malvern, Pershore, Evesham and Stratford-upon-Avon. If the survey finds the board is the limit rather than the supply, that is a fuse board upgrade and we will price it separately so you can decide. Businesses with a fleet or a customer car park want commercial EV charging instead, which is a different calculation again.

Get an EV charger quote

Send a photo of your consumer unit, a photo of your sealed cut-out fuse, and a photo of where the car parks. That is usually enough for a firm number without a visit.

The cost to install an EV charger, and what moves it

The cost to install an EV charger is mostly the run and the supply, not the charger. A unit on the garage wall a couple of metres from the board is a straightforward day. The same charger at the far end of a Victorian terrace, with the board under the stairs and the parking on the street, is a different job entirely. Two things decide it before anything else: the rating of your main fuse, which says whether the supply can carry the charger alongside a shower and a cooker, and your earthing arrangement, which decides whether an earth rod or a device with open-PEN protection is needed. We check both and price the whole thing in writing, and if the answer is that the supply needs upgrading first we say so.
