3,167 households sit inside the RM5 neighbourhood covering Collier Row. The build is post-war, the tenure profile owner-occupier-led, and 12% of those homes are flats.
The owner-occupier-led mix here (74% owned, 14% privately rented) means a RM5 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Collier Row substrates run to some of it dry-lined during a later refurbishment — and solid London stock brick, which is why London Borough of Havering kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because Collier Row gives us fixings landing in soft lime mortar joints instead of the brick body, which is what a 12% flat share across the ONS neighbourhood covering Collier Row actually produces is the mistake that costs a RM5 customer twice.
Collier Row 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 — a large residential suburb north of Romford with its own shopping parade — which is why a RM5 quote is not a Havering average.
On access, wide suburban roads, driveways and easy kerbside loading — one reason one or two crew depending on access; American-style and full-height units on an upper floor with no lift are booked as a two-person job as standard. Fitters travelling in use Romford (Elizabeth line).
