Two things dominate full property rewires on a modern flat in Merthyr Tydfil: developer CU inside a bedroom or kitchen — noise nuisance from RCBO trips, and no SPD in the base install. Both are known variables on this stock, and both belong on the quote — not the invoice.
We work across CF47–CF48 weekly and see the same patterns street after street. That means the quote reflects real experience of this property type, not a template price.
