The starting question with consumer unit upgrades on a 1930s semi is always the same: what does the existing installation test at? Materials and methods we spec on 1930s bay-fronted semi work: 18th Edition metal-clad CU; RCBO per circuit; additional CU for a loft or garage sub-main where the main board is short of ways. Work in Tredegar is planned so that the disruptive part is as short as it can reasonably be. That is the difference between a guess and a measurement.
We treat Tredegar as its own round rather than an outlying job, which is why work in Ebbw Vale tends to be scheduled alongside it. That holds whether the property is owned, let or being sold. We take a steady number of consumer unit upgrades on a 1930s semi enquiries from Tredegar each month, and the pattern is fairly consistent.
