Consumer unit upgrades on a barn conversion touches safety, paperwork and cost, and the three do not always point the same way. We work across CF47–CF48 weekly and see the same patterns street after street. Every circuit affected is identified and labelled, which makes the next person's job — and yours — considerably easier. Around CF47–CF48 it is the single most common reason a job runs long.
If you have had conflicting advice, it is usually because someone quoted without checking focus on the utility or plant room, the consumer. Two electricians looking at the same readings tend to agree. For stone-built valley terraces in Heolgerrig and Cefn Coed that detail matters more than it does elsewhere. Merthyr Tydfil sits inside the area we cover daily, so consumer unit upgrades on a barn conversion here is routine work rather than a special trip.
