Every fuse box / cu enquiry we take from Ystrad Mynach starts in the same place: what is the installation actually doing right now? Whether the property is owner-occupied or let in Ystrad Mynach, the technical work is identical — only the paperwork's recipient changes. It is the difference between a fixed price and an estimate. People often expect the worst outcome. In practice, most Ystrad Mynach visits of this kind end with a defined, limited piece of work. Nothing about it is unusual for property of that age. Fuse box / cu touches safety, paperwork and cost, and the three do not always point the same way.

What's different about Ystrad Mynach
On older Ystrad Mynach 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 will confirm it in writing.
Ystrad Mynach's mix of valley terraces and newer Hengoed estates means CU upgrades often need both SPD and AFDD to suit older and newer circuits side by side, so the new board often needs an earth rod or a TT earthing arrangement if the supply isn't PME. It affects sequence more than cost.
