solid 9-inch brick with plaster-on-lath ceilings. Tight cellar entries, no side-return access, and party walls that can't take a chase.
If you own a Victorian terrace in Cardiff and need consumer unit upgrades, the right spec is usually not the most expensive one. On this stock the sensible answer is metal-clad 18th Edition CU with RCBO per circuit — 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 as standard for surge-sensitive kit, and paperwork the next EICR won't question.
Focus on the under-stairs cupboard, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.
Priced against your Victorian terrace's specific construction, not a template. Route sketched, materials listed, no line-item surprises.
Diary planned for the access constraint that matters on this stock — tight cellar entries, no side-return access, and party walls that can't take a chase.
NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.
Across CF10–CF24 the Victorian terrace stock we've worked on shares consistent patterns: shared party wall with a neighbour, meaning EV/CU cabling has to route through the front elevation or under floorboards, not chase across a shared wall. That local pattern is baked into the quote, not discovered on the day.
Tight cellar entries, no side-return access, and party walls that can't take a chase. Cable routing is planned around the front bay, the hallway and the ceiling voids — not the walls.
Wiring generation on this stock is typically rewired 1970s–1990s, often part-upgraded — a mix of PVC/PVC and older rubber-insulated conductors is common. On a Victorian terrace you should expect us to flag: shared party wall with a neighbour, meaning EV/CU cabling has to route through the front elevation or under floorboards, not chase across a shared wall; no rear access — every cable, board and EV cable enters through the front door or the small back yard; old CPC continuity failures on lighting circuits where junction boxes sit in inaccessible ceiling voids.
Materials and methods we spec on victorian terrace work: metal-clad 18th Edition CU with RCBO per circuit; SPD as standard for surge-sensitive kit; steel-conduit riser for the front-elevation EV feed. Everything is priced on the quote — nothing added on invoice.
Owners of Victorian terrace properties in Cardiff, Penarth and the wider area get one point of contact for the lot — quote, work, certificate, after-care.
No — surveys for Cardiff Victorian terrace enquiries are free. You only pay once the fixed-price scope is agreed.
Same location as the old one, usually under the stairs. We swap in a metal-clad 18th Edition board with an RCBO per circuit and add an SPD in the same case.
For a Victorian terrace usually yes — a 15-minute survey or a set of photos of the under-stairs cupboard and the consumer unit is enough to write a fixed price.
metal-clad 18th Edition CU with RCBO per circuit; SPD as standard for surge-sensitive kit; steel-conduit riser for the front-elevation EV feed. All on the written quote.
Two things: shared party wall with a neighbour, meaning EV/CU cabling has to route through the front elevation or under floorboards, not chase across a shared wall, and the wiring generation — rewired 1970s–1990s, often part-upgraded — a mix of PVC/PVC and older rubber-insulated conductors is common. Both go on the quote, not the invoice.
"Quick, easy and clear with the process! Would definitely call out again for future work." — Lauren Filby, Sockets & Lights — Two Rooms
If you take one thing from this page: the awkward part is the routing, not the install. On a Victorian terrace, tight cellar entries, no side-return access, and party walls that can't take a chase — that's what the quote should reflect.
Calling is faster than a form when the Victorian terrace has quirks (shared party wall with a neighbour). Two-minute triage, honest read on lead time, booked into the diary the same call.
