Consumer unit upgrades for homeowners: what is involved, what it depends on, and what we would check first at a CF47–CF48 address. We work across CF47–CF48 weekly and quote consumer unit upgrades on a fixed-price basis after a short survey. We would rather turn a Merthyr Tydfil job down than take on something we cannot certificate honestly. That is the honest version, rather than the version that sells more work.
Timescales are given honestly. If a part has to come, we say when rather than leaving it open. It is the difference between a fixed price and an estimate. What follows is what we actually do about consumer unit upgrades for homeowners in Merthyr Tydfil, rather than a general description of the trade.
