Barry enquiries about consumer unit upgrades on a post-war semi tend to arrive with a deadline attached — a tenancy, a sale or a fault. Conditions locally play a part — exposure, damp and the way older Edwardian terraces around Holton Road and Cadoxton were built all affect what we find. Most Barry visits settle this within the first hour.
The order of work matters: isolate, test, explain, then price. Skipping the middle two is how people end up paying twice. Older installations around CF62–CF63 show this more often than newer ones. We are asked about consumer unit upgrades on a post-war semi in Barry most weeks, usually after something has changed at the property.
