Domestic Rewiring
Whole-house and partial rewires, planned around how the house actually gets used. Cable runs hidden where they should be, sockets placed where you'll need them, certificates issued on the day.
Domestic and commercial electrical work across Cambridgeshire — done tidily, done quietly, done with an eye for detail. Run by James, working with repeat customers across Cambridge and the surrounding villages for over six years.

Most of the work that comes through this van is repeat business or a name passed at the school gates — quietly, on the basis of jobs done well. The reviews on Google use the same four words on a loop: tidy, on time, fair, meticulous.
One-van operation — me, my tools, and the time I spend in your home. No call-centre booking, no rotating subcontractors, no scuff marks on the skirting boards. If anything isn't right after I've gone, I come back and put it right.
From a single under-cabinet strip to a full garden-lighting design — every one of these photos was taken on a real finished job.







Domestic to commercial, single sockets to whole rewires. If it carries voltage, it's probably already been done in someone's house up the road.
Whole-house and partial rewires, planned around how the house actually gets used. Cable runs hidden where they should be, sockets placed where you'll need them, certificates issued on the day.
Plinth strips, downlights, pendants, statement fixtures. Specified to match the way the room actually gets lived in, not just the floor plan.
Fence wall-washes, deck lights, step lights, planter accents. RCD-protected, fully weatherproofed, properly buried, properly tested.
Extra sockets in the rooms where you keep running an extension lead. USB-A and USB-C, fused spurs for appliances, plaster left untouched.
RCBO swaps, full board upgrades, whole-property surge protection. Older boards brought up to current 18th-edition compliance.
Panel heaters, oil-filled radiators, towel rails. Switched fused spurs, thermostat wiring, properly sized for the room.
Cable runs, sockets, lighting, USB points, sunken floor lights. Turn an empty outbuilding into something you actually want to use.
Tripping circuits, dead sockets, flickering lights. Diagnosed properly on the first visit, with a plain-English explanation of what went wrong and what it'll cost to fix.
Not on the list? Probably still on the books — just ask.
Talk it through with JamesHartford Electrical is run by James — a domestic and commercial electrician working out of Cambridge. The work covers the full spectrum: a double-socket in a back bedroom, a full rewire on a Victorian terrace, kitchen plinth lights that turn the floor into a feature, garden lighting that makes the patio usable in November.
The promise is plain: turn up when I said I would, finish the work to a standard you'd actually want to photograph, leave the place tidier than I found it, charge a fair price for it. After six years on the road around Cambridge, that promise is the only marketing the business has needed.
Friendly, fair on price, leaves the place spotless. Phoned him on a Thursday, sorted by Tuesday.

Used James for two separate jobs over the past year — a kitchen lighting refit and the consumer unit upgrade I'd been putting off. Both times he turned up at the time agreed, did the work cleanly, and the figure he'd quoted on the phone was exactly what landed on the invoice. Worth a lot in itself.
Phoned James on a Thursday after a different sparky had cancelled on us twice. He was round on the Tuesday, did the rewire of our hallway and replaced two old fittings, and tidied up so well there wasn't a fleck of dust on the carpet. We've already booked him for the garden lights in spring.
James fitted recessed lights in our living room. A week later he rang to say he wasn't happy with one of the dimmer switches and would be back to swap it free of charge. We hadn't noticed anything wrong. That kind of follow-up doesn't really happen anymore.
We asked for sockets and lights in the new garden room. James suggested USB-C sockets in the desk wall, sunken floor lights along the path, and a proper outdoor RCD socket for the mower. None of which I'd thought to ask for, all of which we now use every day. Pricing was fair and the install is invisible.
Have used James a handful of times now — replacement sockets, a fused spur for the dishwasher, and once when our outdoor security light decided to flicker constantly. Always sorted same week, always reasonably priced, always honest about whether it's a five-minute job or a half-day.
