We are asked about in Merthyr Tydfil most weeks, usually after something has changed at the property. We work across CF47–CF48 weekly and quote full property rewires on a fixed-price basis after a short survey. Invoice routes to the homeowner as standard. Split billing is the pivot point. Everything quoted after it follows from what the readings say, which is why the survey comes first at any CF47–CF48 address. Which is why the schedule of results is worth reading, not filing.
A written record matters as much as the work. Anything we find at a CF47–CF48 address is documented in a form you can hand to someone else. It takes minutes to confirm and saves hours later. If a previous certificate exists, full property rewires for homeowners usually starts by checking whether it still reflects reality.
