Cardiff: whole property has lost power — what to do now
Whole property has lost power — planned around access rather than around us, which suits tenanted property. Available throughout Cardiff, including Caerphilly.
Do this before we arrive
- Check whether neighbouring properties are also without power before calling anyone out.
- Switch off high-load appliances — cooker, immersion, EV charger — so nothing surges back on when supply returns. It affects timing more than cost.
- In most Cardiff cases: call 105 free from any phone to report and confirm a network outage in your area.
While you wait: never remove or attempt to replace the sealed cut-out fuse before the meter. That is the network operator's equipment, it is unfused on the supply side, and interfering with it is both dangerous and illegal.
Before booking whole property has lost power anywhere in Cardiff Council, it is worth knowing which parts of the job are fixed and which depend on your property.
When every circuit is dead the fault is either upstream of your consumer unit — the service head, cut-out fuse or supply cable — or it is the main switch and tails inside the board. Timing is the other variable. Where a blown DNO cut-out fuse applies, the visit runs longer, and we would rather book the right slot than rush the wrong one. In practice that means checking a blown DNO cut-out fuse 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 if it is a network fault we tell you. 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.
Written with Cardiff housing and Cardiff Council requirements in mind.
What this usually turns out to be
- Weather and exposure play a part locally, and a blown DNO cut-out fuse is the usual result.
- A failed main switch inside the consumer unit — one of several possibilities, all of which get checked.
- Confirming loose or heat-damaged meter tails at the board takes minutes; assuming it wastes a visit.
- A network-side fault or planned outage tends to appear alongside older accessories rather than alone.
How we work through it
- We confirm whether supply is present at the cut-out. Nothing gets replaced on a hunch.
- Access permitting, if it is a network fault we tell you happens in a single visit to your Cardiff address.
- If it is inside the installation we make safe, then the findings are written up before we leave Cardiff.
As with every job in CF10–CF24: attendance and full supply-side diagnosis quoted before we travel; repairs priced in writing after testing.
Why this comes up in Cardiff
Cardiff housing is largely a mix of Victorian and Edwardian terraces in Cathays and Roath, and that shapes how this fault presents.
Commercial calls in Cardiff cluster around Splott, Leckwith and Cardiff Bay business parks; domestic calls spread across the rest of CF10–CF24.
Penarth and Pontypridd sit either side of our Cardiff route, so both are same-week bookable.
Questions we get asked
Who pays if it turns out to be a network fault?
You call 105 and the network operator attends free. If we have already attended and identify it as their fault, we tell you immediately rather than working around it.
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 charge more for Cardiff callouts?
No. Cardiff and the surrounding Penarth and Caerphilly area are inside our standard coverage, so the same callout applies as anywhere else we work.
