The Caerphilly version of this job is shaped by the local housing: new-build estates around Bedwas and Trecenydd. The scope is standard once the physical routing is planned around that construction. A fair amount of this work is preparation: confirming fixed price at quote stage, calibrated to c.1925–1939 construction, planning the route, agreeing what happens if something unexpected appears behind the plaster. It takes minutes to confirm and saves hours later.
Where previous work has no certification behind it, we test it rather than take it on trust. It rarely surprises us; it often surprises the previous quote. If you are weighing up ev charger installation on a 1930s semi at a Caerphilly address, the useful starting point is the age and history of the wiring.
