There is a short version and a long version of full property rewires on a new-build. The short version: test it, then decide. Wiring generation on this stock is typically current — often 17th or 18th Edition compliant at handover but with no headroom. A fair amount of this work is preparation: confirming focus on the utility room or garage, the consumer, planning the route, agreeing what happens if something unexpected appears behind the plaster. It is the kind of detail that separates a tidy job from a callback.
Work in Mountain Ash is planned so that the disruptive part is as short as it can reasonably be. If it turns out not to apply here, you will be told that plainly. Before booking full property rewires on a new-build anywhere in Rhondda Cynon Taf County Borough Council, it is worth knowing which parts of the job are fixed and which depend on your property.
