The SE28 stock around Southmere Lake is post-war. ONS records 47% flats, 53% houses and 7,133 households in Thamesmead.
Owner-occupation runs at 32% in Thamesmead, so alongside the 28% rental churn there is steady planned work — refurbishments, downsizes and probate clearances booked weeks ahead.
Thamesmead substrates run to often with surface conduit, over precast concrete panels and dense blockwork — which is what a 47% flat share across the ONS neighbourhood covering Thamesmead actually produces. Nothing is drilled until the wall has been sounded, because in SE28, drilling blind into a panel with reinforcement or a buried cable behind it — with 39% social-rented stock locally, block access is agreed with the estate office first is the mistake that costs a SE28 customer twice.
Two streets can behave very differently in Thamesmead: brutalist canals and lakes, now under one of London's biggest regeneration programmes. The quote reflects the street the job is actually on. Thamesmead 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: deck-access blocks with limited lifts, long walkway carries and estate service roads. Abbey Wood (Elizabeth line) is the nearest station, and one fitter up to 43 inches, two for anything larger or where the screen has to go up a stairwell.
