The Tredegar version of this job is shaped by the local housing: valley terraces around Sirhowy and Georgetown. Wiring generation on this stock is typically rewired 1970s–1990s, often part-upgraded — a mix of PVC/PVC and older rubber-insulated conductors is common. Timing is the other variable. Where focus on the under-stairs cupboard, the consumer unit location applies, the visit runs longer, and we would rather book the right slot than rush the wrong one. Older installations around NP22 show this more often than newer ones.
The regulations move; installations do not. Part of the job is explaining which differences actually matter and which are simply age. The schedule of results records it either way. If you are weighing up kitchen & bathroom upgrades on a victorian terrace at a Tredegar address, the useful starting point is the age and history of the wiring.
