About Us
Built to Deliver.
J Cowman Electrical Contractors started with one electrician and a van. Today we’re a 10-person team delivering full electrical packages on large-scale residential developments across Leinster.
J Cowman Electrical Contractors is a Safe Electric registered electrical contractor based in Wexford, Ireland. Founded in 2021, the company operates a 10-person team delivering full electrical packages for residential developers, homeowners, and commercial clients across Leinster.
The crew, the vans, the work, Leinster.
Jamie Cowman
Managing Director
Jamie Cowman founded J Cowman Electrical Contractors in 2021 with a clear goal: build an electrical contracting firm that builders could actually rely on. Starting from the tools up, he built a Safe Electric registered crew of 10, and a reputation across Leinster for showing up on time and getting it right.
We work with developers, main contractors, and homeowners who want the job done right. No subcontracting the subcontractor. No finger-pointing. One team, one standard, one cert.
Our Story
From one van to a 10-person crew.
2021
JCowman Electrical founded.
Jamie went out on his own: one electrician, one van, Safe Electric registered from day one.
2022–2023
First hires, first repeat customers.
Grew from solo van to a small crew. Builders started ringing back for the next job, then the one after.
2024–2025
Into large-scale residential.
Stepped up to full electrical packages on residential developments: first fix through to cert, like our 90-unit Dublin build.
2026
10-person crew across Leinster.
Serving Leinster and parts of Munster. Same standard whether it's one rewire or a full development.

On Time. Every Time.
Deadlines aren't suggestions. We plan our work and deliver on schedule, because your build programme depends on it.
Right First Time.
Every connection tested, every circuit certified. We don't cut corners and we don't come back to fix what should have been done right.
Straight Talking.
Clear quotes, honest timelines, no surprises. If there's a problem, you'll hear about it before it becomes yours.
Scale When You Need It.
10-person crew that scales to match your programme: one rewire or a full development. Same Safe Electric-certified standard every time.
Accreditations
Safe Electric A6700
SEAI Registered
Fully InsuredThe Registration
You can check us before you ring us.
Our registration number is A6700, and it sits on the public register that Safe Electric publish and anyone can search. We would tell you to run that check on any electrician before you let them near a board, including us. Registration is not a badge a contractor awards themselves. It is a statutory scheme, it is audited, and a contractor can be removed from it.
What it obliges us to do is issue paperwork. Any new installation or alteration we complete comes with a Completion Certificate, and the testing behind it is recorded on a numbered Test Record. If you are buying, selling or letting and someone asks you for an electrical certificate, those are the Irish documents they mean.

The Work
Most of what we do is new work, not repairs.
The bulk of our year is first fix and second fix on houses and apartments that are being built or gutted. First fix is the cabling stage, done once the structure is up and before the walls close: every circuit run back to where the board will sit, back boxes set, and the whole thing left safe for the plasterer. Second fix is everything visible, which happens after decoration: sockets, switches, fittings, the board itself, then testing and certification.
That order is why an electrician who misses a date costs a builder more than the electrical bill. Nothing behind the plaster can be fixed cheaply once the plaster is on. It is also why we quote off drawings rather than off a phone call on a development, and why we would rather turn a job down than take one we cannot resource.
The domestic side is smaller but it is where most people find us. Roughly half the homes in the counties we cover were built from 1991 onward, and in those the cable is usually fine and the fuse board is the dated part. That is a day of work rather than a rewire, and the fastest way to find out which one you are looking at is the rewire checker, or the era guide for pre-1960s, 1960s to 80s and 1990s to 2000s houses.
We cover the twelve Leinster counties and Waterford. Outside that we are honest about it: travel time lands on your quote and we could not hold the response times we promise, so for a domestic job you are better off with somebody local. The full coverage list is here.

FAQ
Common Questions About J Cowman Electrical Contractors
What size projects do you take on?
From a single socket to a 90-unit development, and most things in between. A 3-bed semi rewire is a job for two of us over 5 to 8 days; a full development we crew up for and run as a phased programme. We have a 10-person team that scales to match the work, so we're comfortable across the full range without dropping the standard.
Are you Safe Electric registered?
Yes. Safe Electric is the body that licenses electrical contractors in Ireland, and the law says only a registered contractor can sign off on the work. We're registered and carry full public liability insurance. Every job is wired, tested and certified to IS 10101 (the current national wiring standard that replaced the old ET 101 rules) and you get the cert to prove it.
How do you fit into our build programme?
We work to your schedule, not ours. First fix goes in once the frame is up and before the plasterers; second fix follows after the walls are closed and the kitchen and units are set; then we test and certify before handover. We'll map those stages around your programme so the electrics never sit on the critical path. We delivered a 90-unit Dublin development that way (phased, unit by unit) so we know how a live site runs.
Do you provide Safe Electric certs for every unit?
Every unit, every time. You get a Safe Electric Completion Cert for each dwelling, the test results behind it, and as-built documentation for the file. That cert is what the ESB looks for before they energise a new connection, and it's what a buyer's solicitor asks for on closing. So it's not paperwork we leave till last.
Do you cover areas outside Wexford?
We're based in Wexford but work across Leinster and beyond. We've delivered projects in Dublin, Waterford and Kilkenny, so the south-east is well inside our patch. For a development we'll put a crew on site for the duration rather than travel daily, which is why distance isn't a barrier for the right job. Tell us where you are and we'll confirm straight away.
How quickly can you quote?
Send us the plans or the spec and we'll come back with a fixed-price quote within 48 hours. For a single domestic job that's usually all we need; for a larger development we'll walk the site first so the number accounts for access, the DB layout and any existing wiring we have to work around. Either way the price is fixed before any work starts: no day rates that creep, no surprises at the end.
Do you install EV chargers?
Yes. We supply and install domestic and commercial EV charging points: including the groundwork, any consumer unit upgrade the charger needs, and a dedicated RCBO-protected circuit to IS 10101. The SEAI home charger grant is worth up to €300 off the install, and we handle that paperwork for you. A standard home install is typically a half-day to a day once the route's agreed.
Do you take on small domestic jobs, not just developments?
Absolutely, from a single socket to a full rewire. As a rough guide, a 3-bed semi rewire runs around €7,000 to €12,000 in 2026, including a new consumer unit and the Safe Electric cert, and takes 5 to 8 working days for a team of two. That is a wide band on purpose: the biggest single variable is making good: whether chasing, replastering and decorating are inside the price or left to you. You can usually stay in the house for a partial rewire, but not a full one. You'll get the same certified standard we bring to the developments, and a fixed quote before anyone lifts a floorboard.
