Before booking anything for consumer unit upgrades on a stone cottage, it is worth knowing which findings change the price and which do not. On a stone cottage you should expect us to flag: TT earthing with an aged earth rod — measured Ra values often above the safe threshold; damp near the incoming supply because the meter sits in an old outhouse; no SPD, and rural supply overhead lines that see genuine lightning-strike risk. What we are really assessing is condition, not age. Cable routing planned around solid stone with lime mortar matters; the date on the board does not, by itself. If it turns out not to apply here, you will be told that plainly.
Anything we recommend is tied to a specific finding rather than to a general principle. Around Rhondda Cynon Taf County Borough Council that is a familiar finding rather than an alarming one. Mountain Ash enquiries about consumer unit upgrades on a stone cottage tend to arrive with a deadline attached — a tenancy, a sale or a fault.
