Costs that appear on the day
In Caerphilly, the most common hidden cost triggers are not mysterious extras; they are practical delays. A crew that cannot load close to the door, enter the building promptly, or move large items through the planned route will spend longer on site.
How to reduce those surprises
Before move day, confirm the exact vehicle position, access code or key arrangement, any stair-only sections, and whether bulky furniture needs partial dismantling. In Caerphilly, those checks prevent the quote from drifting once the crew starts work.
