The kitchens we meet in Millwall
The reason splashback and upstand work in Millwall is quoted per kitchen rather than per metre comes down to the range of rooms these worktops end up in. Waterside flats around the inner dock typically have a galley kitchen of 2.4m to 3m running off the hall, closed on both sides, with the living room kept for the dock view. Some larger units have been opened up, which produces one long run plus an island squeezed against a structural column. Two kitchens on the same street can need different answers. That is why the price follows the template rather than the postcode.
Underfloor heating in a screed rules out fixing into the floor and rules out standing anything heavy on a single point. Splashbacks come off the same slab run as the tops, which means the decision has to be made before fabrication starts. Old walls take a scribed upstand better than a rigid panel.
These flats are built with a floating floor over a concrete slab for acoustic reasons, and it deflects slightly under the weight of a stone island. The plasterboard is genuinely flat here, so a full-height splashback sits well and a slim upstand looks almost redundant, but the sockets are the problem, because they are set out to the developer's original kitchen and often land at odd heights or right on a joint line. Sockets in a stud wall move more easily than sockets in brick.
What the research records here is 1980s dock-edge low-rise, 1990s-2000s waterside apartment block and recent high-rise. What is behind the plaster is different in each, and it matters at fixing.
