The delays people tend to underestimate
In Chesterton, the quietest cost increases usually come from handling time: entry systems, repeated stair trips, longer carries or a less useful van position than expected. narrow internal turns, stepped thresholds, shared hallways and loading routes that break up what should be a quick small move often show up this way.
Because man and van bookings are built around real working time, those delays matter more than most people assume.
How local layout creates extra effort
Victorian terraces, compact houses, flats, shared-entry buildings and some managed apartment developments can look straightforward from outside but still involve awkward corridors, shared halls or several stages before the load reaches the van. Add permit pressure, narrower frontage and limited stopping room can make the workable loading position more awkward than the address first suggests, and a tidy move can start to drift.
The best protection is to describe the full route, not only the address and item count.
