Land Remediation Relief: What is "land in a contaminated state"?: Dig and dump

This guidance applies to expenditure incurred on or before 31 March 2009.

“Dig and dump” is the term used to describe the excavation of contaminated material and its removal to landfill.


A Ltd acquire a site for re-development. Waste by-products containing asbestos were buried on the site. A Ltd conclude that the only option is to dig the waste up and dispose of it in landfill. A Ltd engages the services of a specialist contractor to remove and dispose of the asbestos.

A Ltd can claim Land Remediation Relief as it is remedying the problem of asbestos. A Ltd can also claim Land Remediation Relief on the costs of filling in the hole created by the removal of the asbestos waste, as this restores the ground surface to its former state (FA01/Sch22/Para4 (3)(b)).
