EV Charger Installation in Sheffield

What decides the price

Three things, and none of them is the charger. The first is the cable run: the distance from your consumer unit to where the charger goes, and what it has to pass through on the way. A garage wall backing onto the meter cupboard is a half-hour job; a run from a cellar board, round the house and out to a detached garage is most of a day and considerably more cable.

The second is your existing supply. A charge point needs a dedicated 32A circuit and enough headroom in the main fuse to run it alongside a shower and an oven. Most homes across Yorkshire have an 80A or 100A supply and are fine. Where they aren’t, load curtailment built into the charger solves it without a supply upgrade — the unit simply throttles back when the house is drawing heavily.

The third is the consumer unit. If there’s no spare way, or the board is an older type without RCD protection, that gets sorted first. I’ll tell you before booking, from the photos, not on the day with the van already on the drive.

Earthing, and why nobody digs a hole any more

The technical objection to home charge points used to be PME earthing. On a combined neutral-and-earth supply — which is most of the UK — a broken neutral in the street can put mains voltage on the earthing system, and therefore on the metal body of a car being charged outdoors. The old fix was a separate earth electrode, driven into the ground, well away from any buried services.

Modern chargers detect the fault condition themselves and disconnect, which BS 7671 accepts in place of an electrode. That is what “built-in PEN fault protection” means on the spec sheet, and it is why an install that once needed a rod in the garden now doesn’t. If your chosen charger lacks it, I’ll say so before you buy.

Notification

Every charge point install is notifiable to your Distribution Network Operator — Northern Powergrid for Yorkshire — and under Part P to Building Control. Both are on me. The DNO submission goes in on completion, the NICEIC certificate is issued against the job, and you get copies of both by email within 24 hours. Keep them: your insurer may ask, and a buyer’s solicitor certainly will.

One last thing worth deciding before the survey: where the charger actually goes. The obvious spot is nearest the board, but the one that matters is where the car’s charge port ends up when it’s parked the way you actually park it. A tethered cable that won’t reach round the back of the car is a five-year irritation over a saving of a few metres of cable, and a socketed unit on a narrow drive means carrying a cable in and out. Walk it once with the car on the drive before anything is drilled.
