In Isleworth (TW7) the split is 55% flats to 45% houses over 3,548 households, and the stock is Georgian and early Victorian.
The social-housing-led mix here (46% owned, 21% privately rented) means a TW7 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Isleworth substrates run to precast concrete panels and dense blockwork in TW7, often with surface conduit, with 33% social-rented stock locally, block access is agreed with the estate office first. Nothing is drilled until the wall has been sounded, because Isleworth gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 55% flat share across the ONS neighbourhood covering Isleworth actually produces is the mistake that costs a TW7 customer twice.
Isleworth is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — syon Park, the riverside village at Church Street and the hospital district — which is why a TW7 quote is not a Hounslow average.
On access, narrow riverside lanes prone to tidal flooding, plus driveways in the newer streets — one reason two crew and a Luton for a studio or one-bed; three crew and a second van on two- and three-bedroom apartments or any duplex. Fitters travelling in use Isleworth (South Western).
