Vans, Tools and Equipment: Capital Allowances for Trades 2026/27
Capital allowances are how the tax system gives you relief for the big kit: the van, the mini digger, the scaffold tower, the jetting unit. For 2026/27 the rules moved. Finance Act 2026 cut the main-rate writing down allowance from 18% to 14% and introduced a new 40% first-year allowance, while the £1 million Annual Investment Allowance and the 6% special rate are unchanged. This pillar guide works through the full 2026/27 toolkit for construction trades: what counts as capital rather than a day-to-day expense, how the AIA, the new 40% FYA and the pools interact, buying versus leasing a van, the mileage-rate trap, tools and plant, the drainage question, what happens when you sell an asset, and how all of it feeds a CIS subcontractor's refund.
