What the figure is built from
Four things, and the number of bedrooms is not one of them. The measured volume, taken with a tape rather than inferred. The access at both ends. How much packing you want done. And whether anything is being held.
On a long tenure there is a fifth, and we state it rather than hiding it: how much of the job is decision-making. A house with three decades in it needs more time and more patience than a house of the same measured volume somewhere else, and a quotation that pretends otherwise runs out of day and starts pushing you.
No price, rate card or transit time appears anywhere on this site, because none of them is knowable before a survey. Start on the quote form, or read the questions page.
