Plant & Machinery Allowances (PMA): Long-life assets: Agreement about greenhouses

An agreement was made with the NFU that sophisticated greenhouses, which qualify for allowances as machinery and plant CA22090 are not long-life assets. It says that such glasshouses built to current designs have a useful economic life not exceeding 25 years and will not therefore be long-life assets for the purposes of Capital Allowances. The agreement includes only expenditure incurred up to 31 December 2005 because designs and technology will not stand still. If glasshouses are developed before then that have a useful economic life exceeding 25 years, they will necessarily be outside this agreement.
