We are asked about in Ystrad Mynach most weeks, usually after something has changed at the property. What we are really assessing is condition, not age. Deadline-aware scheduling is default, not a premium matters; the date on the board does not, by itself. Around CF82 it is the single most common reason a job runs long.
Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. For 1970s estates around Hengoed that detail matters more than it does elsewhere. If a previous certificate exists, emergency callouts for airbnb & holiday-let hosts usually starts by checking whether it still reflects reality.
