In Highgate (N6) the split is 65% flats to 35% houses over 5,593 households, and the stock is Georgian and early Victorian.

Steep, narrow lanes where a Luton is the practical limit, plus listed-building constraints. Nearest station is Highgate (Northern), 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.
