Why the property type matters

The CU nearly always sits under the stairs — the swap itself takes 3–4 hours, but the earthing arrangement (still TN-S on many streets) is the variable that decides the price.

Consumer Unit Upgrades on a Victorian terrace in Caerphilly is a physical problem before it is an electrical one. The stock is c.1880–1901, walls are solid 9-inch brick with plaster-on-lath ceilings, and the practical constraint is that 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.

That shapes every line on the quote. We survey the under-stairs cupboard, the cable route and the consumer unit location before pricing — because on this property type the standard scope is only standard once you know what you're working around.

Caerphilly context

Victorian Terrace properties are a distinctive part of the Caerphilly housing mix — new-build estates in Bedwas, traditional valley terraces in Senghenydd, and detached homes towards Abertridwr, particularly around Senghenydd & Abertridwr. We work on this stock weekly.

Written fixed quote
Priced against your Victorian terrace's specific construction, not a template. Route sketched, materials listed, no line-item surprises.

What we build into every quote

Access constraints priced into the diary — a Victorian terrace in Caerphilly isn't the same working day as a new-build with an empty garage.
Wiring generation on record (rewired 1970s–1990s, often part-upgraded — a mix of PVC/PVC and older rubber-insulated conductors is common) so the quote reflects what's actually in the house, not what the brochure assumes.
Fixed price at quote stage, calibrated to c.1880–1901 construction — not a generic South Wales rate.
Certificate at the end, delivered the same evening, in the format your next EICR or agent will expect.

FAQs — victorian terrace in Caerphilly

Do you need to see the property before quoting?+

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.

Where does the new consumer unit go in a Victorian terrace?+

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.

What materials do you spec on this property type?+

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.

What's specific about consumer unit upgrades on a Victorian terrace?+

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.

Will the work affect any original features?+

Not unless the quote says so. On period stock in particular we route through floors, lofts and non-original plaster; cornices, dado rails and original panelling stay intact.

Construction & access

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 & likely findings

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 we spec

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.
