Cardiff is a straight M4 run from our Caldicot base, about 35 minutes, and it's another patch we cover most weeks. Between EICRs on rental portfolios around Cathays and Roath, EV chargers on Pontprennau and Radyr driveways, and commercial fit-outs around the Bay and Callaghan Square, our vans are in CF postcodes regularly.
The city's housing spans the full range you'd expect from a capital: Victorian terraces packed tight around Cathays, Roath and Grangetown; interwar semis through Rhiwbina, Whitchurch and Llanishen; large post-war estates in Llanrumney, Ely and Llanedeyrn; and modern developments at Pontprennau, Old St Mellons and along the Bay. Each era brings its own wiring quirks, and we've worked them all.
On the commercial side, Cardiff gives us the full picture: retail units on Queen Street and St Mary Street, hospitality electrics around Cardiff Bay, offices at Callaghan Square and Central Square, and industrial and warehouse units on Rover Way and Ocean Park. Different scale, same NAPIT-registered team, same insurance.
For homeowners in Cardiff, the most common calls are Ohme EV charger installs, consumer unit upgrades to 18th Edition RCBO boards, and full rewires on pre-1980s terraced stock. For landlords, EICRs and HMO compliance are the weekly workstream.

What's specific to Cardiff
Local property, local problems.
The stuff generic electricians miss, because they haven't spent enough time working Cardiff property to see the patterns.
Cathays and Roath HMO stock
Cardiff's student and shared-let belt around the universities means HMO compliance work, fire alarm interlinking, emergency lighting, EICRs, is a weekly job for us in CF24 and CF10.
Victorian terraces with layered rewires
Grangetown, Canton and Roath terraces have often been part-rewired over decades. Mixed cable eras spurred together is the classic EICR failure and needs a proper scope, not a patch.
Damp and coastal weather around the Bay
Anything near Cardiff Bay or Penarth Marina takes salt-laden weather. External sockets, garden lighting and outdoor units need IP-rated enclosures and stainless fixings, indoor-grade kit doesn't last.
Older consumer units on interwar estates
Rhiwbina, Whitchurch and Llanishen stock often still runs early split-load or wire-fuse boards. 18th Edition RCBO upgrades are one of the most-quoted single jobs across the city.
Long supply runs on new-build estates
Pontprennau, Old St Mellons and St Edeyrns properties sometimes have meters placed well away from where the EV charger needs to sit. That's a proper cable-route survey before we quote, not a guess.
Retail and hospitality unit changeovers around the Bay & city centre
Tenant changes on retail and hospitality units regularly need new lighting, distribution changes and periodic EICRs to hand over cleanly. We handle it end-to-end.
