Post-War Semi consumer unit upgrades — Mountain Ash (CF45)

cavity brick with plasterboard finishes, concrete lintels. Good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the CU generation.

Call for Mountain Ash Get a quote

Most post-war semi properties across Mountain Ash were rewired 1990s–2010s; kitchen and bathroom often updated separately with mixed board vintages. That single fact drives the consumer unit upgrades conversation more than any brochure spec ever does — we're inheriting a wiring generation, not starting from scratch.

The quote we send is calibrated to that inheritance: what's testable, what needs remedial work, what's genuinely fine as it stands. No wholesale "modernise everything" pitch when the existing installation is sound.

What to expect

01
Photo or on-site survey
Focus on the hallway or garage, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.
02
Written fixed quote
Priced against your post-war semi's specific construction, not a template. Route sketched, materials listed, no line-item surprises.
03
Booked around access
Diary planned for the access constraint that matters on this stock — good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the cu generation.
04
Certificate + evidence pack
NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.

What we build into every quote

Common post-war semi findings we flag before quoting: kitchen refit added post-rewire, socket circuit no longer matches the original ring layout.
Access constraints priced into the diary — a post-war semi in Mountain Ash isn't the same working day as a new-build with an empty garage.
Wiring generation on record (rewired 1990s–2010s) so the quote reflects what's actually in the house, not what the brochure assumes.
Fixed price at quote stage, calibrated to c.1945–1965 construction — not a generic South Wales rate.

Construction & access

Good loft access, generous under-floor voids and a straightforward driveway make the physical work easy; the variable is always the CU generation.

Wiring generation & likely findings

Wiring generation on this stock is typically rewired 1990s–2010s; kitchen and bathroom often updated separately with mixed board vintages. On a post-war semi you should expect us to flag: kitchen refit added post-rewire, socket circuit no longer matches the original ring layout; bathroom shower feed on a 6mm radial with an isolator hidden above the ceiling; outside tap or outside socket added on a spur without RCD protection.

Materials we spec

Materials and methods we spec on post-war semi work: metal-clad 18th Edition CU with RCBO per circuit; SPD retrofit; shower feed uprated to 10mm where the run length demands it. Everything is priced on the quote — nothing added on invoice.

Mountain Ash context

Across CF45 the post-war semi stock we've worked on shares consistent patterns: kitchen refit added post-rewire, socket circuit no longer matches the original ring layout. That local pattern is baked into the quote, not discovered on the day.

FAQs — post-war semi in Mountain Ash

Is there a call-out or survey fee?+

No — surveys for Mountain Ash post-war semi enquiries are free. You only pay once the fixed-price scope is agreed.

Is a CU swap enough for a post-war semi, or do I need a rewire?+

A CU swap is usually enough. We test every circuit at survey and only recommend rewiring where the readings genuinely justify it.

Do you need to see the property before quoting?+

For a post-war semi usually yes — a 15-minute survey or a set of photos of the hallway or garage and the consumer unit is enough to write a fixed price.

What materials do you spec on this property type?+

metal-clad 18th Edition CU with RCBO per circuit; SPD retrofit; shower feed uprated to 10mm where the run length demands it. All on the written quote.

What's specific about consumer unit upgrades on a post-war semi?+

Two things: kitchen refit added post-rewire, socket circuit no longer matches the original ring layout, and the wiring generation — rewired 1990s–2010s. Both go on the quote, not the invoice.
