The Same Standard, Every Job.
At J Cowman Electrical, we deliver complete electrical packages for projects of every scale, from large residential and commercial developments to one-off new builds and full property rewires. With a focus on quality workmanship, reliability, and safety, we work closely with builders, developers, and homeowners to deliver electrical solutions tailored to each project. Whether it's a modern housing development, a commercial fit-out, or a domestic rewire, we bring the same standard to every job.
Start Here
Most houses we look at do not need rewiring.
47.4% of the homes across the thirteen counties we cover were built in 1991 or later, and in those the cable is usually fine. What is out of date is the fuse board. The wiring rules are national and the county you live in changes nothing, so the thing that actually decides the job, the price and the disruption is the decade the house went up. Find yours below.
Shares are of 1,028,339 dwellings with a stated year built across Carlow, Dublin, Kildare, Kilkenny, Laois, Longford, Louth, Meath, Offaly, Waterford, Westmeath, Wexford and Wicklow. Source: CSO Census 2022, table FY033A. Pulled 2026-08-05.
If the trip switch keeps going, start with the board
It is the single most common call we get, and in a house built after 1991 it is very rarely a wiring fault. What the board does, when it genuinely needs replacing, and what that costs.
