In Edmonton (N9) the split is 47% flats to 53% houses over 17,818 households, and the stock is mainly Victorian.
The social-housing-led mix here (33% owned, 34% privately rented) means a N9 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Walls are often with surface conduit — and precast concrete panels and dense blockwork, which is what a 47% flat share across the ONS neighbourhood covering Edmonton actually produces, so the fixing that matters in Edmonton is chosen on site — the usual failure here is Edmonton gives us drilling blind into a panel with reinforcement or a buried cable behind it, the reality on the streets around Edmonton Green Market.
Edmonton 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 — market, shopping centre and dense post-war housing on the Lea valley flat — which is why a N9 quote is not a Enfield average.
Getting to the door matters as much as the job: tower blocks with a single goods lift, estate service roads and market congestion. Edmonton Green (Greater Anglia) is the nearest station, and three to six operatives depending on the plant, with skates, pallet trucks and a tail-lift 7.5t as standard and a HIAB where a machine cannot be moved to the bay by hand.
