A small van holds about 6 m³, which is a studio with not much furniture. A Luton holds 18 m³ and covers most two-bed flats. A 7.5 tonne lorry holds 38 m³ and does a three or four bed house in one load. The mistake people make is booking by bedrooms instead of by volume. A two-bed flat with a piano, a garage of tools and a loft full of boxes is not a two-bed flat to a mover — it is 26 cubic metres. Use the calculator on the home page. It is the same arithmetic a surveyor does, with the same figures.
