- Land in a ‘contaminated state’. ‘Contaminated state’ means, in short, that ‘relevant harm’ is being caused, or there is a serious possibility of ‘relevant harm’, or it could cause significant pollution in groundwater, streams, rivers or coastal waters.
- Land in a ‘derelict state’. ‘Derelict state’ means not in productive use and cannot be put into such use without the removal of structures or buildings.
- Land contaminated by hazardous substances, pollutants, structural threats.
- Typical costs incurred would be asbestos removal, dealing with harmful organisms, demolitions.
- The land was contaminated by the claimant, or became contaminated or derelict during the company’s ownership
- The contaminants are naturally occurring (but specific relief is allowed for naturally occurring arsenic, radon, and Japanese knotweed)
- The expenditure has already been subsidised
- The expenditure could obtain relief under the ‘normal’ capital allowances regime
- The cost of the land was discounted, and terms in the agreement for acquiring it was stated to include necessary remediation works
- The land is a nuclear site
