Tredegar enquiries about full property rewires on a stone cottage tend to arrive with a deadline attached — a tenancy, a sale or a fault. 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. Where an installation has been extended over decades, the sensible approach is to establish a baseline before adding anything else to it. You will get the plain version, not the technical one, unless you ask.
The order of work matters: isolate, test, explain, then price. Skipping the middle two is how people end up paying twice. Materials matched to the stock is the part worth confirming rather than assuming. We are asked about full property rewires on a stone cottage in Tredegar most weeks, usually after something has changed at the property.
