If you own a period flat in Merthyr Tydfil 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 sized to the sub-main — 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, and paperwork the next EICR won't question.
Freeholder or managing-agent consent almost always required for CU work. We handle the letter chain if needed.
Wiring generation on this stock is typically conversion-era 1990s–2010s; sub-main from the communal supply, individual metering. On a period flat you should expect us to flag: sub-main tails routed through communal areas — freeholder consent needed for CU work; communal lighting on a separate meter, not always tested with the flat's EICR; old landlord's supply feeding hallway heaters or emergency lighting.
Materials and methods we spec on period flat conversion work: metal-clad 18th Edition CU sized to the sub-main; SPD as standard; communal-area emergency lighting where the freeholder brief includes it. Everything is priced on the quote — nothing added on invoice.
Focus on the hallway, the consumer unit location, and the intended cable route. Usually 15–30 minutes on-site or a short photo set.
Priced against your period flat'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 — freeholder or managing-agent consent almost always required for cu work.

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

metal-clad 18th Edition CU sized to the sub-main; SPD as standard; communal-area emergency lighting where the freeholder brief includes it. All on the written quote.
Two things: sub-main tails routed through communal areas — freeholder consent needed for CU work, and the wiring generation — conversion-era 1990s–2010s. Both go on the quote, not the invoice.
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.
