Storage heater not heating up — Caerphilly callout and diagnosis
Storage heater not heating up — planned around access rather than around us, which suits tenanted property. Applies to storage heater not heating up anywhere in Caerphilly, Cardiff or Newport.
Do this before we arrive
- For new-build estates around Bedwas and Trecenydd especially — check whether every heater is cold or just one — that single fact halves the diagnosis.
- Look at the consumer unit for a separate off-peak section or a second board, and check nothing is switched off there. That detail is easy to verify.
- Note the time the heaters used to come on; if the tariff or meter changed recently, tell us. It goes on the report.
While you wait: never cover a storage heater or dry clothes on it. The thermal cut-out that protects it is a last line of defence, not a thermostat.
This page covers storage heater not heating up for property in Caerphilly and the surrounding CF83 postcodes, in the order the work happens.
Every property we attend in and around Caerphilly gets the same order of operations, and it starts with establishing a failed time switch or contactor no longer switching. The regulations are specific about it, so there is little room for opinion.
Caerphilly properties near Cardiff are covered on the same schedule, so a joint visit is often possible if a neighbour needs the same thing. Which is why the schedule of results is worth reading, not filing.
Photographs of anything hidden are taken as standard, because you should not have to take our word for what is above the ceiling. It takes minutes to confirm and saves hours later.
storage heater not heating up in Caerphilly is rarely identical to the same job twenty miles away: new-build estates around Bedwas and Trecenydd behave differently from newer stock, and the CF83 postcode covers both. It rarely surprises us; it often surprises the previous quote.
Timing is the other variable. Where a failed time switch or contactor no longer switching applies, the visit runs longer, and we would rather book the right slot than rush the wrong one. We would rather rule out a failed time switch early than discover it late.
The paperwork for storage heater not heating up is only useful if it reflects what is actually installed, which is why circuits get identified rather than assumed. Most Caerphilly visits settle this within the first hour.
The intention of this page is to save you a wasted visit, not to create one. Where a smaller repair solves it, that is what gets quoted.
References to local streets and areas are to Caerphilly itself, not the wider region.

Where the problem usually sits
- It is common for a tripped thermal cut-out after the heater was covered to be mistaken for something more serious.
- A meter or tariff change — the point at which a small job can turn into a larger one.
- A failed time switch or contactor no longer switching — cheap to confirm, expensive to guess at.
- Where one or more open-circuit heating elements inside the unit shows up, we test the neighbouring circuits too.
How the job runs
- Access permitting, we test the off-peak supply at the board happens in a single visit to your Caerphilly address.
- Where elements have failed we advise honestly on repair — no shortcuts, because the paperwork has to stand up.
- You are shown we test the off-peak supply at the board before we ask you to sign anything.
As with every job in CF83: off-peak supply testing and element checks quoted per visit; element or heater replacement priced after diagnosis.

Questions we get asked
What if I disagree with a finding?
You are welcome to get a second opinion. The readings are on the certificate so anyone can repeat them.
Does this affect my insurance?
Insurers generally want evidence that the installation has been inspected and any defect addressed. The certification is that evidence.
Can two jobs be combined into one visit?
Usually. If you need something else doing at the same CF83 address, say so when booking and it is priced together.
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 Caerphilly property.
How quickly can you get to Caerphilly?
We come in via the A469, A468 and A470, and Caerphilly is on our regular round, so we normally offer a slot within a few days.
