In Hanworth (TW13) the split is 39% flats to 61% houses over 6,014 households, and the stock is inter-war.
The social-housing-led mix here (49% owned, 17% privately rented) means a TW13 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Hanworth substrates run to precast concrete panels and dense blockwork; locally that also means often with surface conduit, which is what a 39% flat share across the ONS neighbourhood covering Hanworth actually produces. Nothing is drilled until the wall has been sounded, because Hanworth gives us drilling blind into a panel with reinforcement or a buried cable behind it, and with 17% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a TW13 customer twice.
Hanworth 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 — a quiet residential district around Hanworth Park and the old air park — which is why a TW13 quote is not a Hounslow average.
Wide suburban roads with driveways and easy turning. Nearest station is Feltham (South Western), and one person and a car for boot-loads; two crew and a 3.5-tonne Luton for anything from a quarter-load upward.
