In Totteridge (N20) the split is 12% flats to 85% houses over 3,519 households, and the stock is mixed-era.
The owner-occupier-led mix here (75% owned, 14% privately rented) means a N20 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are cavity brickwork outside, over timber stud partitions inside, which is what a 12% flat share across the ONS neighbourhood covering Totteridge actually produces, so the fixing that matters in Totteridge is chosen on site — the usual failure here is a four-hole bracket with two screws in a stud and two in fresh air, as the Totteridge stock goes, the pattern behind 3,519 households inside the N20 neighbourhood.
Totteridge 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 — green-belt lane of large houses, paddocks and a village pond — which is why a N20 quote is not a Barnet average.
On access, long gravel drives, narrow lanes without passing places and gated entrances — one reason a two-person crew and a Luton for flats; three or four crew and two vans for houses with lofts, cellars or garages. Fitters travelling in use Totteridge & Whetstone (Northern).
