You can spend a lot on consumer unit upgrades for cafés & restaurants or very little. Which one is right depends on measurements, not on the quote. Cafés & Restaurants in Cardiff usually only book consumer unit upgrades once a real trigger has landed — environmental health visit, insurance renewal, a kitchen fit-out, or a repeated RCD trip in service. Local housing here is largely Victorian and Edwardian terraces across Cathays and Roath, and that shapes both the likely findings and the realistic scope. Around Cardiff Council that is a familiar finding rather than an alarming one.
The regulations move; installations do not. Part of the job is explaining which differences actually matter and which are simply age. It gets photographed if it will be hidden afterwards. Consumer unit upgrades for cafés & restaurants sits somewhere between routine and urgent depending on what the property is doing right now.
