solid or mixed masonry, partition walls timber-framed with plasterboard. Freeholder or managing-agent consent almost always required for CU work.
Period-flat CU swaps need freeholder consent because the tails run through communal areas — we draft the letter with the quote.
The awkward part of consumer unit upgrades on a Ystrad Mynach period flat isn't the install — it's the route. Freeholder or managing-agent consent almost always required for CU work. We handle the letter chain if needed.
We map the route at survey, mark it up on a photo, and price against that specific plan. Nothing gets discovered mid-job that could have been priced at quote stage.
Period Flat Conversion properties are a distinctive part of the Ystrad Mynach housing mix — 1970s estates in Hengoed, traditional terraces in Nelson, and rural smallholdings towards Penpedairheol, particularly around Hengoed & Nelson. We work on this stock weekly.

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.
NICEIC certificate, photo evidence of hidden work, Part P where applicable — all emailed the evening the job signs off.
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.
Usually yes, because the tails route through common areas. We send a standard consent letter with the quote you can forward to the managing agent.
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.
Common enough that we work on this stock most weeks. 1970s estates in Hengoed, traditional terraces in Nelson, and rural smallholdings towards Penpedairheol — the period flat is a recognisable slice of that mix.
