If you are weighing up consumer unit upgrades for warehouses & trade units at a Merthyr Tydfil address, the useful starting point is the age and history of the wiring. We quote consumer unit upgrades across CF47–CF48 on a fixed basis, invoice the business, and deliver the paperwork in the format your insurer expects. We take the view that same-week for standard scope, planned longer where the shutdown should be established before a price is written, not after. That is slower to quote and cheaper to complete. It takes minutes to confirm and saves hours later.
We would rather turn a Merthyr Tydfil job down than take on something we cannot certificate honestly. It rarely surprises us; it often surprises the previous quote. Consumer unit upgrades for warehouses & trade units looks the same on every website. What differs is how it is scoped, and that is what this page is about.
