In Pimlico (SW1) the split is 93% flats to 7% houses over 7,917 households, and the stock is post-war.
With 39% private renting against 27% owner-occupied, most SW1 bookings land on a move-in day rather than a weekend.
Pimlico substrates run to precast concrete panels and dense blockwork in SW1, often with surface conduit, which is why Westminster City Council kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because Pimlico gives us drilling blind into a panel with reinforcement or a buried cable behind it, which is what a 93% flat share across the ONS neighbourhood covering Pimlico actually produces is the mistake that costs a SW1 customer twice.
Pimlico sits inside the Congestion Charge zone as well as ULEZ, so both are itemised on the quote rather than absorbed into an hourly rate. What shapes the job more is the neighbourhood itself — cubitt's white stucco grid between Victoria and the river, quieter than its neighbours — which is why a SW1 quote is not a Westminster average.
Getting to the door matters as much as the job: resident-permit streets all week, basement flats down steep steps and no lifts in most conversions. Pimlico (Victoria) is the nearest station, and two to three operatives as standard, with a specialist F-gas engineer booked in for any unit holding refrigerant-charged equipment.
