Ask three electricians about consumer unit upgrades for warehouses & trade units and you may get three answers. Ours is based on what the readings say. Warehouse DB upgrades are usually driven by an EV fleet, machine addition or LED conversion — one visit, planned as a project. The practical question for a Aberdare property is not what usually happens, but what this installation actually shows when it is tested. The regulations are specific about it, so there is little room for opinion.
Aberdare properties near Merthyr Tydfil are covered on the same schedule, so a joint visit is often possible if a neighbour needs the same thing. Which is why the schedule of results is worth reading, not filing. The starting question with consumer unit upgrades for warehouses & trade units is always the same: what does the existing installation test at?
