Shops and retail units — electrical work in Cardiff
Shops and retail units — planned around access rather than around us, which suits tenanted property. Booked across Cardiff and CF10–CF24 on the same terms as the rest of our area.
Before booking shops and retail units anywhere in Cardiff Council, it is worth knowing which parts of the job are fixed and which depend on your property.
Retail electrical work is dominated by two things: display lighting that has to look right, and trading hours that make daytime isolation expensive. Timing is the other variable. Where distribution boards with no accurate circuit schedule after successive applies, the visit runs longer, and we would rather book the right slot than rush the wrong one. In practice that means checking distribution boards with no accurate before anything is replaced.
Local housing here is largely Victorian and Edwardian terraces across Cathays and Roath, and that shapes both the likely findings and the realistic scope. It is written into the report either way, so nothing is hidden.
Most enquiries reaching us from Cardiff arrive after something has already been tried. Starting from measurements rather than the previous attempt saves time. Anyone testing properly will reach the same conclusion.
Nothing is charged for on the basis of a guess. Where a reading is borderline, it is reported as borderline. It rarely changes the price, but it does change the plan.
Every property we attend in and around Cardiff gets the same order of operations, and it starts with establishing emergency lighting and exit signage. We would say the same to a family member.
Photographs of anything hidden are included so you can see what we saw. Certification and paperwork are part of the job, not an optional extra at the end.
Weather and exposure play a part locally, and distribution boards with no accurate circuit schedule after successive is the usual result.
Chillers and display cabinets sharing an RCD — one of several possibilities, all of which get checked.
Confirming illuminated signage supplies run externally without weatherproof glanding takes minutes; assuming it wastes a visit.
Emergency lighting and exit signage tends to appear alongside older accessories rather than alone.
Fixed wire testing (EICR) scheduled outside trading hours. Nothing gets replaced on a hunch.
Access permitting, distribution board labelling, circuit schedules and dedicated RCBOs happens in a single visit to your Cardiff address.
Shop-front and display lighting design, install and LED retrofit, then the findings are written up before we leave Cardiff.
We emergency lighting installation plus monthly and annual test regimes; anything borderline is flagged rather than buried.
Additional till, chiller and signage circuits with correct isolation, then a walk-through so you know what changed.
Cardiff and its immediate neighbours are the intended audience for this page.

Where we get called in
- Fixed wire testing (EICR) scheduled outside trading hours
- Distribution board labelling, circuit schedules and dedicated RCBOs for stock-critical loads It affects timing more than cost.
- In most Cardiff cases: shop-front and display lighting design, install and LED retrofit
While you wait: commercial premises are covered by the Electricity at Work Regulations 1989, which require installations to be maintained in a safe condition. In practice that is evidenced by a periodic EICR plus emergency lighting and portable appliance records.
The local mix includes letting agents and city-centre cafés and retail, which changes what we carry on the van.
If you are just outside Cardiff — Penarth, Caerphilly, Pontypridd — the same rates and response apply.
What tends to go wrong on these sites
The Cardiff picture
One local factor worth planning for: Cardiff Bay properties get more wind-driven rain than the city centre, so outdoor work near the bay benefits from upgraded IP-rated enclosures.

Commercial questions we get asked
How often does a shop need an EICR?
Commercial installations are commonly inspected on a five-year cycle, with shorter intervals where the environment or usage justifies it. Your insurer or landlord may specify the interval in the lease.
What should I have ready before you arrive?
Access to the board and to the affected area, plus any previous certificates. That is enough to start at the Cardiff property.
Can you talk to my letting agent directly?
Yes, if you tell us who to contact. Access and reporting can both go through them.
What is not included?
Building work, decoration and anything outside the electrical scope. Those are flagged rather than absorbed.
Do you cover Cardiff for commercial work?
Yes — Cardiff and Penarth, Caerphilly are inside our standard commercial coverage, reached via the A470 and A48.
As with every job in CF10–CF24: retail work is normally staged so isolation happens before opening or after close, with any unavoidable daytime work confined to a single circuit at a time.
