Downsizing from a 3 or 4-bed family home of many years usually means a significant reduction in possessions before move day. By the time the driver arrives, the kept items often fit a large van or sometimes a medium. The volume of a long-term family home is no longer what's being transported.
Multi-stop bookings are common on these moves. Some items go to charity shops, some to storage for later decisions, and the main load goes to the new home. A single driver works through all the addresses in order, one booking. Beds, wardrobes and dining furniture often need dismantling at the family home and rebuilding at the new property. Flag this in the booking notes so the driver allocates time and brings the right tools.
