The starting question with consumer unit upgrades for warehouses & trade units is always the same: what does the existing installation test at? If you are a warehouse in Cardiff looking for consumer unit upgrades, the practical questions are simple: how fast, how much, and what does the certificate say. The regulations move; installations do not. Part of the job is explaining which differences actually matter and which are simply age. We would rather rule out 15-30 minute walk with early than discover it late.
The regulations set the standard; NICEIC certificate, photo evidence sets the effort required to meet it at your particular address in Cardiff Council. Most Cardiff visits settle this within the first hour. We take a steady number of consumer unit upgrades for warehouses & trade units enquiries from Cardiff each month, and the pattern is fairly consistent.
