Every consumer unit upgrades on a barn conversion enquiry we take from Neath starts in the same place: what is the installation actually doing right now? The scope is standard once the physical routing is planned around that construction. The cost drivers here are access and condition rather than parts. Priced against your barn conversion's specific construction, not a template is the one that moves a quote most. Most Neath visits settle this within the first hour.
Anything we recommend is tied to a specific finding rather than to a general principle. Older installations around SA10–SA11 show this more often than newer ones. Consumer unit upgrades on a barn conversion touches safety, paperwork and cost, and the three do not always point the same way.
