Why Choose Us in Offaly
The county that has almost stopped building, so nearly every job is on a house somebody lives in.
Offaly's residential and commercial markets benefit from our willingness to travel for the right projects. Birr is known for its Georgian streetscape, which means careful rewires on period and protected houses, while Tullamore and Edenderry have newer estates that take full first-fix-to-handover packages. Out towards Banagher and the Shannon, it's mostly rural bungalows and farmhouses needing rewires and consumer unit upgrades. We bring the same crew and the same IS 10101 certification to Offaly as we do to our home county, with fixed-price quotes and delivery on the agreed programme. We also cover neighbouring Laois and Westmeath.
What makes Offaly different
Offaly has almost stopped building. Only 6% of the county's homes have gone up since 2011, the lowest share of any county we cover, and completions have fallen from 543 in 2023 to 323 in 2025, a drop of 41% and the steepest on our patch. Meanwhile 6,847 Offaly houses, close to a quarter of the county, were standing before 1961. Put those two facts together and the shape of the work here is settled: Offaly is a retrofit county. Very little of what we do is first fix on a bare site. Nearly all of it is rewires, fuse boards and fault finding in houses that somebody is living in that week, with the furniture still in them and the heating still needed at night. That is a genuinely different job from the same work on an empty build, and the difference shows up in the sequence far more than in the price.
Offaly Housing Stock
What decides the job here is when the house was built
The wiring rules are national. What actually changes the work is the decade, and Offaly’s stock has its own shape: 42.3% of homes here were built 1991 – 2010. Find your era below and follow it through to the detail.
| Built | Homes in Offaly | Share | What that usually means |
|---|---|---|---|
| Before 1961 | 6,847 | 24.3% | Rubber or lead-sheathed cable. Usually a genuine rewire. |
| 1961 – 1990 | 7,691 | 27.3% | Depends which end of the band. Fuse wire and no RCD are common. |
| 1991 – 2010 | 11,897 | 42.3% | Sound cable, dated board. Almost never a rewire. |
| 2011 onward | 1,709 | 6% | Nothing degrading. Capacity for a charger or a heat pump is the question. |

On The Ground In Offaly
The job is not the same across the county
Tullamore takes nearly half the county's building
604 of Offaly's 1,259 completions went up around Tullamore, 48% of everything, with 389 around Edenderry and 274 around Birr. Tullamore holds most of the county's recent estate stock, which is the housing least likely to need anything more than a board. But even there the numbers are small: 604 homes over three years in the busiest part of the county is roughly four a week. Compare Kildare's 6,302 or Meath's 5,290 across the same period and the difference in what an electrician does all day becomes obvious.
Birr and the Georgian stock need a different approach
Birr's core is Georgian and a good deal of it is protected structure, which changes a rewire before any wiring question is reached. Cable routes have to work with lath and plaster rather than through it, original joinery and cornice are not chase material, and surface containment is sometimes the honest answer where a chase is not. Work to a protected structure can need consent from the local authority, so the first conversation on a Birr period house is about what is permitted, not about a price. We would rather raise that at the survey than halfway through.
Why almost every Offaly job is a retrofit
With only 1,709 homes in the county built since 2011 and the build rate falling, the work here is on the 26,435 that were already standing. That has a practical consequence worth stating plainly: we are usually working around you. Rewiring an occupied house means the power comes back on every evening, one part of the house stays live while another is stripped, and the sequence gets planned around which rooms you actually need. It takes longer than the same house empty and it costs more to do properly, and any quote that ignores that is quoting the wrong job.
The pre-1961 houses out in the country
6,847 Offaly homes predate 1961, and out past Banagher, Ferbane and the Shannon that mostly means farmhouses and cottages rather than town terraces. Those houses have often been extended twice, so three wiring vintages can meet at one board: rubber-insulated cable from the original build, PVC from a 1980s extension, and something recent feeding a shed or a pump. Add a farmyard supply or a well and the installation stretches well beyond the house. We test the lot together, because on this kind of property the fault people chase indoors for weeks is frequently outside.
