Census 2021 puts High Barnet at 4,475 households with a median age of 43.3. The mainly Victorian stock is owner-occupier-led, which is why 66% houses and 34% flats need different handling in EN5.
Private renting sits at 24% and owner-occupation at 68%; the first group books pre-move-in cleaning at short notice, the second plans it.
Walls are solid London stock brick in EN5, some of it dry-lined during a later refurbishment — where 68% owner-occupation means the same home is booked again rather than a new tenant each year, so the fixing that matters in High Barnet is chosen on site — the usual failure here is in EN5, fixings landing in soft lime mortar joints instead of the brick body — the pattern behind 4,475 households inside the EN5 neighbourhood.
Two streets can behave very differently in High Barnet: historic market town at the top of the Northern line, with a hill high street. The quote reflects the street the job is actually on. High Barnet is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, steep Barnet Hill, narrow high-street loading and driveways on the estates — one reason one cleaner for a flat; two for a house, so the property is finished in one visit rather than split across a day. Fitters travelling in use High Barnet (Northern).
