Fuse box replacement in Caerphilly
Replace your old Caerphilly fuse box with a modern 18th Edition consumer unit. Fixed price, single-day fit, Part P notified.
You can spend a lot on fuse box / cu or very little. Which one is right depends on measurements, not on the quote. The practical question for a Caerphilly property is not what usually happens, but what this installation actually shows when it is tested. Check board, tails, earthing is the part worth confirming rather than assuming. The regulations move; installations do not. Part of the job is explaining which differences actually matter and which are simply age. Which is why the price follows the test rather than the other way round. Fuse box / cu sits somewhere between routine and urgent depending on what the property is doing right now.
- Power off typically 4–6 hours You will see the reading yourself.
- Old rewireable / BS 3036 boards swapped We flag it rather than assume you know.
- On older Caerphilly terraces, the existing meter tails are — often visible once the accessory is taken off the wall.
- The steep mountain road access to Senghenydd and Abertridwr. That is the finding, not the diagnosis.
- Where fittings have been changed over the years, where the meter tails are too short to reach is the usual culprit.
What's different about Caerphilly
Where the meter tails are too short to reach a new board position, we coordinate with the DNO for a meter relocation — we book this for you, no extra cost. You will see the reading yourself.
On older Caerphilly terraces, the existing meter tails are often undersized (16mm² where modern requires 25mm²). We replace them at the same time so the upgrade is genuinely compliant. We flag it rather than assume you know.
Old rewireable / BS 3036 boards swapped. We would rather find this on a planned visit than an urgent one.
Look for 18th Edition Amendment 2 RCBO-per-circuit option before assuming the board is at fault.
