CIRD63205 | Land Remediation Relief: Qualifying Land Remediation Expenditure: Fencing and security
From HM Revenue & Customs · Corporate Intangibles Research and Development Manual
The costs of fencing around a site and security for the site only qualify for Land Remediation Relief where they would not have been incurred but for the land being contaminated, see CIRD63100.
For example if a higher standard of security fencing has to be installed whilst decontamination takes place then the additional cost of that higher standard of fencing may qualify for Land Remediation Relief.
