In Kenton (HA3) the split is 16% flats to 84% houses over 6,923 households, and the stock is inter-war.
The owner-occupier-led mix here (66% owned, 26% privately rented) means a HA3 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Kenton substrates run to timber stud partitions inside; locally that also means cavity brickwork outside, and easy — driveways and wide roads on almost every street. Nothing is drilled until the wall has been sounded, because a four-hole bracket with two screws in a stud and two in fresh air, as the Kenton stock goes, and with 26% of homes here privately rented, it sets the booking date as often as the job does is the mistake that costs a HA3 customer twice.
Kenton 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 — uniform interwar semis between Harrow and Wembley, quiet and residential — which is why a HA3 quote is not a Harrow average.
On access, easy — driveways and wide roads on almost every street — one reason one or two crew depending on access; American-style and full-height units on an upper floor with no lift are booked as a two-person job as standard. Fitters travelling in use Kenton (Bakerloo, Overground).
