Two things dominate kitchen & bathroom upgrades on a HMO in Merthyr Tydfil: communal-area lighting on a shared circuit with an individual room — a licence-fail issue, and BS 5839-6 Grade D interlinked alarm system with mixed-vintage sensors. 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.
