The Neath version of this job is shaped by the local housing: semi-rural cottages around Cimla. Every commercial job leaves with a written scope of works, itemised invoice, matching certificate and photo evidence — the pack your insurer or landlord expects. The paperwork for consumer unit upgrades for warehouses & trade units is only useful if it reflects what is actually installed, which is why circuits get identified rather than assumed. We quote against the trigger is the part worth confirming rather than assuming.
A fair amount of this work is preparation: confirming priced to your insurance renewal, invoice routed, planning the route, agreeing what happens if something unexpected appears behind the plaster. Which is why the price follows the test rather than the other way round. If you are weighing up consumer unit upgrades for warehouses & trade units at a Neath address, the useful starting point is the age and history of the wiring.
