solid stone with lime mortar, thick internal walls, timber ceilings. Solid-stone walls mean cable chasing is off the table — routing goes through skirting, floors and lofts.
Cottage CU swaps almost always come with a new earth rod — the existing Ra reading is usually well above the safe threshold.
If you own a stone cottage in Mountain Ash and need consumer unit upgrades, the right spec is usually not the most expensive one. On this stock the sensible answer is new earth rod with tested Ra reading — matched to the wiring generation, not a lift-and-shift from a new-build brochure.
That is the standard we quote to. Fixed price, honest survey, SPD retrofit (genuinely useful in rural exposure), and paperwork the next EICR won't question.
Stone Cottage properties are a distinctive part of the Mountain Ash housing mix — Edwardian terraces in Penrhiwceiber, ex-NCB cottages in Miskin, and post-war estates in Abercynon, particularly around Penrhiwceiber & Abercynon. We work on this stock weekly.
Focus on the outhouse or pantry, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.
Priced against your stone cottage's specific construction, not a template. Route sketched, materials listed, no line-item surprises.

NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.
Common enough that we work on this stock most weeks. Edwardian terraces in Penrhiwceiber, ex-NCB cottages in Miskin, and post-war estates in Abercynon — the stone cottage is a recognisable slice of that mix.

Wiring generation on this stock is typically rewired 1990s–2010s; earthing arrangement often TT with an earth rod. 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.
Materials and methods we spec on stone cottage work: new earth rod with tested Ra reading; SPD retrofit (genuinely useful in rural exposure); surface-run steel conduit where wall-chasing isn't an option. Everything is priced on the quote — nothing added on invoice.
Beyond Mountain Ash itself, we regularly cover stone cottage work across Aberdare, Pontypridd, Merthyr Tydfil on the same fixed-price model — same materials, same certificate format.
If you take one thing from this page: the awkward part is the routing, not the install. On a stone cottage, solid-stone walls mean cable chasing is off the table — routing goes through skirting, floors and lofts — that's what the quote should reflect.
Calling is faster than a form when the stone cottage has quirks (TT earthing with an aged earth rod — measured Ra values often above the safe threshold). Two-minute triage, honest read on lead time, booked into the diary the same call.
