The SE23 stock around The Horniman Museum and Gardens is mainly Victorian. ONS records 58% flats, 42% houses and 6,684 households in Forest Hill.
Owner-occupation runs at 54% in Forest Hill, so alongside the 27% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Forest Hill substrates run to with metal stud partitions between rooms, over dot-and-dab plasterboard over blockwork — where 54% 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 short screws that grip only the board and slowly lever it off the dabs on these streets — which is why London Borough of Lewisham kerb rules get settled before the van is loaded is the mistake that costs a SE23 customer twice.
Two streets can behave very differently in Forest Hill: the Horniman Museum, the hill views and a compact village centre. The quote reflects the street the job is actually on. Forest Hill is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it.
On access, steep gradients, narrow hill roads and permit bays around the station — 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 Forest Hill (Overground).
