You should be able to get good quality screened topsoil with added compost
in bulk from local horticultural suppliers.
When we bought ours it ranged from £15 per tonne for small amounts down to
£80 for a full 10 tonne load. Needless to say we bought the full ten tonnes
and shared with a neighbour.

I need quite a lot of soil/compost to fill my raised beds, locally I can
only seem to find 30 litre bags at sill prices. Does anybody know a bull
supplier of somebody who sells bags by the hundred at reasonable rates.
