Two things dominate full property rewires on a ex-council semi in Ystrad Mynach: council-era MK plastic split-load CU still installed — reliable but no SPD, no per-circuit RCBOs, and external meter cabinet with the tails routing through an exterior wall — sometimes on an older tails spec. Both are known variables on this stock, and both belong on the quote — not the invoice.
We work across CF82 weekly and see the same patterns street after street. That means the quote reflects real experience of this property type, not a template price.
