In Edmonton (N9) the split is 47% flats to 53% houses over 17,818 households, and the stock is mainly Victorian.
Because 34% of Edmonton is privately rented and 32% socially rented, a lot of N9 work is agreed with a landlord or managing agent rather than the person opening the door.
Walls are precast concrete panels and dense blockwork in N9, often with surface conduit, with 32% social-rented stock locally, block access is agreed with the estate office first, 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, a median age of 34 in this neighbourhood shapes what gets ordered here.
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 one technician with a portable extraction machine and air mover on a single household booking; two technicians on HMO, student accommodation and serviced-apartment rounds where six or more mattresses are cleaned in a day.
