The special rate pool applies to specific categories of qualifying plant and machinery that are relieved more slowly than main pool expenditure. It is particularly relevant where a project includes building systems or integral features.
Typical special rate assets include electrical systems, lighting, heating, ventilation, air conditioning, water systems, lifts and certain other features within a building. These costs are often embedded in construction or refurbishment budgets and require careful extraction from wider works.
The analysis must determine whether the expenditure is on a qualifying integral feature or another special rate asset, rather than on the structure itself. It must also distinguish replacement, alteration and improvement costs from non-qualifying building works.
Special rate pool expenditure may be eligible for AIA or, for companies in specific circumstances, a relevant FYA. If upfront relief is not available, the expenditure is pooled and relieved at the special rate through writing down allowances.
Project documentation is central to the claim. Cost plans, M&E specifications, contractor valuations and technical input can help ensure that qualifying systems are identified correctly and not treated as general structure or residual SBA expenditure.
