Plant and machinery definition

What does Plant and machinery mean? In legal practice, plant and machinery describes the equipment, apparatus and machines a business uses to carry on its trade, as distinct from the land or buildings in which it operates. The expression is used across multiple contexts and, for specific purposes, is informed by legislation and case law. For tax, what counts as plant and machinery determines entitlement to capital allowances (UK: Capital Allowances Act 2001; Ireland: Taxes Consolidation Act 1997), including treatment of fixtures and integral features. For non-domestic rating/valuation, regulatory lists identify which plant and machinery is rateable (with separate regulations in England and Wales, Scotland and Northern...

UK corporation tax: plant and machinery capital allowances—qualifying expenditure, pooling, writing-down and first-year allowances, disposals and balancing charges, claims, time limits and loss relief

Published by a LexisNexis Tax expert

Practice notes

FORTHCOMING CHANGES:

At Budget 2025, the government confirmed that Finance Bill 2026 will legislate for:

a cut in the writing-down allowance rate for main pool plant and machinery from 18% to 14%, applying from 1 April 2026 for corporation tax and 6 April 2026 for income tax—this will affect companies and unincorporated businesses with main rate pools, including expenditure that is ineligible for, or predates, first-year allowances (such as the super-deduction and full expensing)
a new 40% first-year allowance for qualifying main rate expenditure incurred from 1 January 2026, with fewer restrictions than other FYAs—primarily advantageous where spend is not otherwise covered by the £1m AIA or existing FYAs (including full expensing); available to all businesses and covering assets used for leasing (but not overseas leasing), while excluding cars and second-hand assets
a one-year extension of the 100% green first-year allowances for qualifying spend on zero-emission cars and electric vehicle charging points, to 31 March 2027 for corporation tax and 5 April 2027 for income tax

Tomlin orders in England and Wales: CPR guidance on drafting, confidentiality, approval, variation, enforcement, limitation, CCA issues, court-specific requirements, sample wording and precedents

This Practice Note This Practice Note reviews mechanisms used in settling litigation. A Tomlin order consists of a consent order paired with a schedule. It operates to stay proceedings on terms that have been agreed. The provisions contained in the schedule may remain confidential. This Practice Note describes the scope of confidentiality attaching to the schedule and sets out how it differs from a standard consent order. Sample wording for a Tomlin order is included, alongside links to precedents, as well as guidance on court approval. It also addresses varying, setting aside and enforcing a Tomlin order, including the considerations the court will take into account when handling applications for each. Further guidance is provided on interpreting and applying the relevant provisions of the CPR; however, some courts and divisions impose very specific requirements for both drafting and approval, and for approaching the schedule and confidentiality issues. Accordingly, you must consider the particular rules and court guide provisions in the forum where your claim is proceeding when drawing up the Tomlin order...
