Walk Newington Green from Newington Green's 1658 terrace outwards and the Georgian and early Victorian pattern is obvious: 89% of the 3,496 households in N16 live in flats, 11% in houses.
29% of households rent privately and 24% own, which is why school clearance demand here peaks around tenancy changeovers and completion dates.
Newington Green substrates run to often with surface conduit, over precast concrete panels and dense blockwork — where 24% owner-occupation means the same home is booked again rather than a new tenant each year. Nothing is drilled until the wall has been sounded, because drilling blind into a panel with reinforcement or a buried cable behind it on these streets — the pattern behind 3,496 households inside the N16 neighbourhood is the mistake that costs a N16 customer twice.
Two streets can behave very differently in Newington Green: historic green with London's oldest brick terrace, ringed by cafés and conversions. The quote reflects the street the job is actually on. Newington Green is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: green-side loading limits, one-way streets and permit bays all week. Canonbury (Overground) is the nearest station, and two to four operatives for a single-building clear, scaling to two teams working in parallel where a full primary site has to be finished inside a two-week holiday window.
