Walk Collier Row from Collier Row Lane parade outwards and the post-war pattern is obvious: 12% of the 3,167 households in RM5 live in flats, 88% in houses.
Private renting sits at 14% and owner-occupation at 74%; the first group books all hanging and mounting services at short notice, the second plans it.
Collier Row substrates run to solid London stock brick; locally that also means some of it dry-lined during a later refurbishment — where 74% owner-occupation means the same home is booked again rather than a new tenant each year. Nothing is drilled until the wall has been sounded, because in RM5, fixings landing in soft lime mortar joints instead of the brick body — measured on the walk in from Romford (Elizabeth line) rather than assumed from a map is the mistake that costs a RM5 customer twice.
Two streets can behave very differently in Collier Row: a large residential suburb north of Romford with its own shopping parade. The quote reflects the street the job is actually on. Collier Row is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
Getting to the door matters as much as the job: wide suburban roads, driveways and easy kerbside loading. Romford (Elizabeth line) is the nearest station, and one fitter for a typical multi-item visit; two where anything crosses 30kg or has to be carried up a shared stairwell.
