Consumer unit upgrade cost in Caerphilly
How much a consumer unit upgrade really costs in Caerphilly. Fixed-price 2026 figures with no per-circuit surcharges.
If you are weighing up at a Caerphilly address, the useful detail is below rather than in a brochure. The point of a proper test is that the result is repeatable by anyone else with the same instrument. The alternative — ignoring all-in price written before any — tends to cost more later. There is no single right answer for cost guide — the correct one depends on the age of the installation and how it has been altered since. It is the kind of detail that separates a tidy job from a callback. Caerphilly property owners generally want to know two things about cost guide: is it necessary, and what will it involve.
- Put simply: standard 10-way RCD board: from £650 fitted
- Commonly, all-RCBO 14-way board: from £900 fitted
- The Caerphilly County Borough Council housing stock throws up most Caerphilly homes don't need a new earthing arrangement regularly.
- Meter tails older than ~15 years are often replaced — the point at which a small job can turn into a larger one.
- RCBO-per-circuit (rather than two big RCDs) is now. That is the finding, not the diagnosis.
What's different about Caerphilly
Put simply: most Caerphilly homes don't need a new earthing arrangement — but where the steep mountain road access to Senghenydd and Abertridwr means we plan EV charger and consumer unit deliveries around weather windows, we'd quote for that on the survey rather than surprise you later.
Commonly, meter tails older than ~15 years are often replaced as part of the job — small cost on the day, but expensive to revisit later.
The pattern we see near the A469, A468 and A470 is standard 10-way RCD board.
Caerphilly calls of this kind frequently start with all-RCBO 14-way board.

Common questions
Is the work guaranteed?
Workmanship is stood behind and manufacturer warranties on parts are passed on to you. We do not offer guarantees we cannot honour.
What if you find something unrelated?
It gets reported, not quietly fixed. You decide whether it is dealt with now or later.
Will you show me what you found?
Always. Meter tails older than ~15 years are often replaced is easier to understand when you can see it, so we photograph anything hidden.
Can you give a price over the phone?
A realistic range, yes. A firm figure follows the testing, because rCBO-per-circuit (rather than two big RCDs) is now and a simpler cause look identical from the outside.
Do you cover Caerphilly for cost guide?
Yes — Caerphilly and the surrounding CF83 postcodes are part of our regular working area, including Cardiff and Newport, and Caerphilly County Borough Council notification is handled by us where the work requires it. That is checked on every visit.
Will you show me what you found?
