If you own a modern flat in Pontypridd and need consumer unit upgrades, the right spec is usually not the most expensive one. On this stock the sensible answer is SPD retrofit — matched to the wiring generation, not a lift-and-shift from a new-build brochure.
That is the standard we quote to. Fixed price, honest survey, RCBO-per-circuit CU where the base board only had RCDs, and paperwork the next EICR won't question.
