In Croydon (CR0) the split is 71% flats to 29% houses over 13,716 households, and the stock is mainly Victorian.
Because 43% of Croydon is privately rented and 22% socially rented, a lot of CR0 work is agreed with a landlord or managing agent rather than the person opening the door.
Expect dot-and-dab plasterboard over blockwork; locally that also means with metal stud partitions between rooms, measured on the walk in from East Croydon (Southern, Thameslink, Tramlink) rather than assumed from a map behind the plaster in CR0. That is why fixings are picked in the room rather than off a van shelf, and why Croydon gives us short screws that grip only the board and slowly lever it off the dabs, where 34% owner-occupation means the same home is booked again rather than a new tenant each year is the fault we are called back to undo.
Croydon is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — office towers, Boxpark, the tram network and one of the biggest town centres in the south-east — which is why a CR0 quote is not a Croydon average.
Getting to the door matters as much as the job: tram tracks limit kerbside loading, one-way system throughout and booked lifts in every tower. East Croydon (Southern, Thameslink, Tramlink) is the nearest station, and one fitter for a room or a straight flight; two for large open-plan floors, winder staircases and anything carried up above the third floor without a lift.
