Bolton · BL1–BL9 · est. 2011
NICEIC Approved Contractor
Part P · 18th Edition
Every job priced on this page. Ring and you already know the figure.
Fuse boards, EICRs, EV chargers, sockets and faults, for houses and landlords across Bolton. Written quote before I start, certificate emailed the same evening, mess taken away with me.
Start here — five seconds
Four different problems, four different answers. Only one of them needs you to ring me this minute.
A scorched socket or a hot smell from the board is the one thing on this page I want you to treat as urgent, whatever the hour.
Every price I charge is published further down this page, and the estimator will give you a figure in about twenty seconds. Send a photo of your consumer unit with the form and half my questions are answered before I get in the van.
Before I get there, do this
This is the part of the site I would keep if I had to delete everything else. Do these and you are safe until I arrive — and often you will not need me at all.
The big switch on the left of the consumer unit kills the lot. If you are not sure what you are looking at, that is the one with 100A or MAIN SWITCH written on it. Off is down.
Whatever you had just switched on when the power went — that is your suspect. Unplug it and leave it unplugged, even if the power comes back.
Stay out of that room, keep the door shut, and do not put the power back on to "just check". Burning smells do not clear themselves.
Once is a fault clearing itself. Twice is the protection doing its job. Forcing it a third time is how a nuisance trip turns into a fire.
And the honest bit If the answer is "unplug the tumble dryer and you are fine", I will tell you that on the phone and charge you nothing. I would rather have the rewire in four years than eighty quid tonight.
Circuit schedule — rates in force from 1 April 2026
Fixed prices, confirmed in writing before I start. If the job turns out smaller than the quote, you pay the smaller figure.
£140up to 6 circuits
Every circuit tested dead and live, board photographed, results emailed as a signed PDF the same evening. £15 per circuit above six — a three-bed semi is usually eight or nine. Remedials quoted line by line, never bundled into one frightening number.
£560up to 8 ways
Metal 18th-edition board, RCBO per circuit so one fault no longer kills the whole house, surge protection fitted as standard. £45 per way above eight. Landlord pack — alarms tested, agent-ready set — £45. £40 off where three or more properties are booked in the same week. Includes main bonding check, Part P notification and the certificate. One day, power off around four hours.
£8997.4kW, up to 10m
Supply capacity calculated properly before I quote, not after. Dedicated circuit from the board, load curtailment where the main fuse needs it, DNO notification submitted for you. £12 per metre beyond ten, £140 if the run has to go under the drive.
£95first double socket
Extra doubles, USB sockets, outside sockets, downlights, garden and garage supplies. £55 each thereafter on the same visit — so four sockets in one morning is £260, not four call-outs. Chases filled and made good, ready for your decorator.
£75first hour, then £45
Insulation resistance, continuity, RCD ramp testing — the actual diagnostic work rather than guessing. Most household faults are found inside the first hour. No call-out charge before 6pm: you pay for time on the tools, not for the van arriving.
£185per property, all in
EICR up to eight circuits, plus alarm and CO test, plus the certificate set formatted for your agent and emailed within 24 hours. £165 each for three or more properties booked in the same week.
Work it out yourself
The same arithmetic I do in the van, run on the same published rates. Nothing hidden, nothing to unlock with your phone number.
Two jobs with their own rules
Landlords & agents
Every rented property in England needs a satisfactory report every five years and at change of tenancy. The tenant gets a copy in 28 days, the council gets it in 7 if they ask, and the fine for not having one runs to £30,000. That is the whole law, in four lines.
Turnaround: tested Tuesday, PDF in your inbox Tuesday night. Multiple properties get booked as one round so the whole portfolio carries the same expiry date and you stop tracking eleven of them.
EV charging
The honest answer for a fair number of Bolton houses is "yes, but". Most 1930s semis around here still sit on a 60A or 80A main fuse, and a 7.4kW charger wants 32A of it. I work that out first, on paper, with your actual meter readings — not after the box is on the wall.
Recent work — 11 June 2026
Three-bed semi, 1936, rewireable fuse box that had been in the hall cupboard since the Coronation. One day, board swapped, house back on before the kids got home.
Job sheet
Same board, same day rate you can work out yourself further up this page. No survey visit charged, no second trip — the quote given on the phone was the invoice given at the door.
Credentials
You are letting a stranger into your house and then trusting his signature on a legal document. Here is everything you would be entitled to ask for at the door.
Issued date · Ref no.
What it is like having me in the house
The man who quotes is the man who tests and the man who comes back if something is not right. No rotating crew, no apprentice left on his own with your ceiling.
Dust sheets on carpets and stairs before anything comes off the wall. Boots off upstairs. If drilling makes dust, the vacuum comes out afterwards — mine, not yours.
I tell you before it happens, roughly how long, and I will work around the freezer, the home office call and the baby's nap if you tell me when they are.
Old fuse box, offcuts, packaging, the lot. Nothing goes in your bin and nothing gets left in the garage "for the tip".
Card, Apple Pay or bank transfer when the job is finished and you are happy. No deposit on anything under £500.
On the invoice, not in a policy document you have to ask for. If a socket I fitted stops working in year five, I come back and it costs you nothing.
What the job was, and what they said
Fuse board · three-bed on Chorley Old Road · in and out in a day
“Quoted £605 on the Thursday, charged £605 on the Friday. Told me exactly when the power was going off so I could move the freezer stuff to next door. The cupboard was tidier when he left than when he got here.”Helen R., BL2 · June 2026
Four EICRs · flats above the High Street · all four in one day
“My agent needed certificates before the tenancies started on the Monday. Danny did all four on the Thursday and the PDFs were in my inbox that night. Two C2s, both quoted separately, no drama, no scare tactics.”Marcus O., landlord, BL3 · May 2026
Kitchen circuit tripping · Bromley Cross · one hour
“Two other electricians told me I needed a rewire. He found a nail through a cable behind the units in about forty minutes, fixed it, charged me the hour. That is why he has my number now.”Priya S., BL5 · March 2026
Where I go, and how long I take

The patch, drawn out
Not part of the fiction
Voltmark Electrical is a fictional concept site, so a form on this page wouldn’t reach anyone. The note alongside is the actual way to get in touch with Kalen Tech.
Asked at eleven at night
Almost always moisture or a failing appliance, not your wiring. Kettles, washing machines, immersion heaters and outside lights are the usual four. An RCD is looking for a few thousandths of an amp leaking to earth, so a slightly damp outside socket is enough. Unplug everything on that circuit, reset, then reintroduce items one at a time — the one that trips it is the one that is broken. If it trips with nothing plugged in, it is the cable, and that is a fault-find job.
You need one if yours has rewireable fuses, no RCD protection, or a cracked plastic case. You probably want one if you are having an EV charger, a shower or a kitchen done, because the board has to be right before anything new hangs off it. You do not need one just because an electrician looked at it and made a face — an older board that tests fine and has working RCD protection can stay. If yours is fine, I will tell you it is fine.
A device that cuts the power in about 30 milliseconds when electricity starts flowing somewhere it should not — usually through a person. An MCB protects the cable from overload; an RCD protects you. A modern board gives every circuit its own RCBO, which is both in one module, so a fault in the garden lights no longer takes the fridge and the router with it.
Usually not. "Unsatisfactory" means at least one C1 or C2 was found. A C1 is genuine present danger — I make that safe before I leave the property, every time, and you will know about it because I will have told you at the door. A C2 is potentially dangerous: it has to be fixed, but it is a job for next week, not tonight. If your report is all C2s and C3s, sleep normally and ring me in the morning.
Rarely, and it is the most oversold job in the trade. Rubber or fabric-covered cable, black rubber sheathing, round pin sockets or no earth to the lighting means yes. PVC twin-and-earth from the 1970s onward that tests within limits does not, whatever its age. Most Bolton houses I see need a new board, a few circuits improved and the bonding brought up to date — a day or two, not a fortnight and a skip.
For a board change, around three to four hours in one block, and I will schedule it around your day. For sockets or lighting, usually 20 minutes a circuit and only the circuit I am working on. For an EICR, brief interruptions circuit by circuit — if you work from home, tell me and I will do the office ring last, or first, whichever suits your calls.
Yes: £2m public liability, and I will email the certificate before I start rather than after you ask twice. Same with the NICEIC registration, which you can also check yourself on their register by putting my postcode in. The full record is in the credentials block further up this page.
