Consumer unit upgrade cost in Mountain Ash
How much a consumer unit upgrade really costs in Mountain Ash. Fixed-price 2026 figures with no per-circuit surcharges.
Cost guide is worth doing properly once rather than cheaply twice. Every property we attend in and around Mountain Ash gets the same order of operations, and it starts with establishing standard 10-way RCD board. We would rather rule out standard 10-way RCD board early than discover it late. Timescales are given honestly. If a part has to come, we say when rather than leaving it open. Most Mountain Ash visits settle this within the first hour. Here is how cost guide works in practice for a property in Mountain Ash, start to finish.
- Frequently — all-RCBO 14-way board: from £900 fitted
- Earth rod / TT install add-on if needed We will confirm it in writing.
- A recurring one across CF45: standard 10-way RCD board.
- Damp ingress and age combine, and all-RCBO 14-way board is the outcome.
- Earth rod / TT install add-on if needed. We photograph anything we find so you can see it yourself.
What's different about Mountain Ash
Frequently — most Mountain Ash homes don't need a new earthing arrangement — but where the dense Penrhiwceiber terraces have shared party walls that affect cable routing for rewires and EV chargers, we'd quote for that on the survey rather than surprise you later.
Meter tails older than ~15 years are often replaced as part of the job — small cost on the day, but expensive to revisit later. We will confirm it in writing.
SPD surge protection optional add-on tends to appear alongside other signs rather than alone.
Part P notification always included, which explains why the problem comes and goes rather than staying put.
How we'd do it

- 3CertifySingle-day swap, typically 4–6 hours. Nothing gets replaced on a hunch.

Common questions
Do you handle larger planned projects?
Yes, phased across a programme so the Mountain Ash site stays usable while work proceeds.
Can two jobs be combined into one visit?
Usually. If you need something else doing at the same CF45 address, say so when booking and it is priced together.
Will you work on a tenanted property?
Yes. We arrange access with the tenant directly if you prefer, and the report goes to you as the Mountain Ash landlord.
How do you decide what actually needs doing?
By testing first. RCBO-per-circuit (rather than two big RCDs) is now is confirmed or ruled out with instruments before anything is quoted for the Mountain Ash property.
