The W1 stock around The Wallace Collection is Georgian and early Victorian. ONS records 88% flats, 12% houses and 3,555 households in Marylebone.
57% of households rent privately and 32% own, which is why cooker cleaning demand here peaks around tenancy changeovers and completion dates.
Marylebone substrates run to with metal stud partitions between rooms, over dot-and-dab plasterboard over blockwork — and with 57% of homes here privately rented, it sets the booking date as often as the job does. Nothing is drilled until the wall has been sounded, because in W1, short screws that grip only the board and slowly lever it off the dabs — measured on the walk in from Marylebone (Bakerloo, Chiltern Railways) rather than assumed from a map is the mistake that costs a W1 customer twice.
Two streets can behave very differently in Marylebone: village high street, Georgian estate streets and the medical quarter along Harley Street. The quote reflects the street the job is actually on. Marylebone sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate.
On access, estate-managed streets, single-yellow evening restrictions and mansion blocks with porters and small lifts — one reason one technician for a freestanding cooker; two for 110cm ranges, where the doors alone are a two-person lift. Fitters travelling in use Marylebone (Bakerloo, Chiltern Railways).
