01
Start with access, not a headline price
A skip stays at the site while you fill it. A grab lorry arrives to load an agreed pile with its hydraulic arm. The better option depends on the site layout, material and working programme. A low advertised price is not a useful comparison unless the allowed waste, capacity, transport and any extras match.
02
When a grab may suit
A substantial loose stockpile and a safe, reachable loading point make a grab worth considering. You need to have material ready for the agreed visit. Check the vehicle approach and overhead clearance before assuming the arm can solve a difficult access problem.
03
When a skip may suit
A job that produces material gradually may benefit from a container remaining on site. You still need space, access for placement and collection, and the right permissions where the container is outside private land. Check the permitted waste and weight limits with the supplier.
04
Compare the same job
Use the comparison tool to record ready-to-collect versus gradual waste, access and loading preferences. Then ask suppliers for quotes on the same material and quantity. Do not convert a skip volume directly into grab tonnes without a density assumption.
