Census 2021 puts Chiswick at 15,273 households with a median age of 39.5. The mainly Victorian stock is mixed-tenure, which is why 43% houses and 57% flats need different handling in W4.
34% of households rent privately and 51% own, which is why flat-pack assembly demand here peaks around tenancy changeovers and completion dates.
Chiswick substrates run to with metal stud partitions between rooms — and dot-and-dab plasterboard over blockwork — the reality on the streets around Chiswick House and Gardens. Nothing is drilled until the wall has been sounded, because in W4, short screws that grip only the board and slowly lever it off the dabs — which is why London Borough of Hounslow kerb rules get settled before the van is loaded is the mistake that costs a W4 customer twice.
Two streets can behave very differently in Chiswick: chiswick House, the riverside and Bedford Park's Arts and Crafts streets. The quote reflects the street the job is actually on. Chiswick is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, conservation-area rules, A4 red route and very tight CPZ around Turnham Green — one reason one fitter for most items; two for sliding-door wardrobes, bunk beds and anything that has to be carried up a shared stairwell. Fitters travelling in use Turnham Green (District, Piccadilly).
