Why the property type matters

Ex-council semis are near-identical within an estate — we've seen the exact same layout twenty times, so the CU quote is fast and firm.

Consumer Unit Upgrades on a ex-council semi in Mountain Ash is a physical problem before it is an electrical one. The stock is c.1945–1980, walls are cavity brick, concrete-frame lintels; some steel-framed variants require careful drilling around lintels and cills, and the practical constraint is that external meter cabinet on the front elevation on most estates — tidy cable route into the hallway, easy cu swap.

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.
