Leasing, second-hand assets, and the green transition:

The capital allowance reforms taking effect in 2026 introduce opportunities for some investment models while tightening the position for others. Changes to first year allowances (FYA), writing down allowances (WDA), and eligibility rules are reshaping how businesses evaluate leasing, second hand assets, and sustainability driven investment, particularly where existing 100% reliefs are unavailable or not claimed.

As tax incentives increasingly influence asset acquisition strategies, the reforms raise important questions — particularly for leasing companies, asset heavy operators, and organisations seeking to balance financial efficiency with environmental objectives.

Recent reforms reflect a targeted policy shift: retaining existing 100% reliefs in key cases while introducing a new 40% FYA and moderating long term relief through a reduced main rate WDA. These changes affect not only how quickly tax relief is obtained, but also which types of assets and ownership models are likely to benefit most.

As a result, leasing structures, asset age, and expected asset life play a more visible role in determining tax outcomes, with wider commercial and sustainability considerations often assessed alongside the tax analysis.

A significant shift in the availability of first year relief

One of the most notable developments is the introduction of a 40% FYA for certain qualifying main rate assets acquired for leasing. Historically, assets provided for lease were often excluded from accelerated reliefs, although full expensing and the AIA continue to provide 100% relief in cases where their own conditions are satisfied.

From 1 January 2026, this restriction is relaxed in part. A 40% first year allowance may be available for qualifying new and unused main rate plant and machinery acquired for leasing, subject to the statutory conditions being met.

Implications for pricing and funding models

Where a lessor can access earlier capital allowance relief, this may improve after tax cash flow and, in some cases, influence:

• lease pricing structures
• asset funding costs
• return on investment modelling

Commercial considerations remain paramount, but the reform may increase the tax relevance of leasing structures for qualifying expenditure.

Limited eligibility for first year relief

In contrast, second hand assets remain excluded from the 40% FYA. This maintains a clear distinction between new and previously used assets within the capital allowances framework.

As a result, businesses acquiring second hand equipment generally continue to rely on:

• the Annual Investment Allowance (AIA), where available, or
• writing down allowances, including at the reduced main pool rate where AIA or other FYAs are not available.

Tension with reuse and circular economy objectives

The exclusion of second hand assets from the new 40% FYA has attracted attention in the context of sustainability and reuse. From a tax perspective, the reforms continue to place stronger upfront incentives on qualifying new expenditure, rather than extending equivalent accelerated relief to reused assets.

This creates a degree of tension where commercial or environmental goals prioritise circular economy principles, but tax relief is delivered more slowly.

Interaction between tax policy and sustainability goals

Many businesses now factor environmental considerations into investment decisions, including asset longevity, reuse, and energy efficiency. However, capital allowances are asset driven rather than outcome driven, meaning eligibility depends on statutory classifications rather than environmental impact.

Slower relief for longer life and reused assets

The reduction in the main rate writing down allowance from April 2026 for corporation tax purposes, and from 6 April 2026 for income tax purposes, has a disproportionate effect on assets with longer economic lives, particularly where those assets are reused or fall outside accelerated allowances. While total relief remains available, it is spread over a longer timeframe.

This can influence internal investment appraisals, particularly where reused or longer life assets are compared against qualifying new expenditure with faster tax recovery.

When leasing may offer advantages

With expanded FYA eligibility for certain qualifying leased assets, leasing structures may become more attractive in some scenarios, particularly where previous restrictions limited access to accelerated relief.

When purchasing new assets may deliver stronger tax outcomes

For some investment types, direct acquisition of qualifying new assets may continue to produce faster tax relief than leasing or purchasing second hand equipment, depending on the nature of the expenditure, the taxpayer, and the availability of AIA, full expensing, or other FYAs.

Balancing tax efficiency with commercial and sustainability priorities

Tax incentives are only one element of a wider decision making process. Businesses should consider:

• asset usage and expected life
• financing and cash flow requirements
• interaction with wider capital allowance strategy
• environmental and operational objectives.

The 2026 reforms highlight the government’s attempt to balance stimulating business investment and managing fiscal cost. While sustainability considerations are relevant to business decision making, the capital allowances framework remains driven primarily by statutory asset categories and specific relief conditions.

As policy continues to evolve, businesses operating in leasing, asset reuse, and sustainability focused sectors should monitor how future incentives adapt to environmental priorities and longer term asset strategies.

Taken together, the reforms create a clearer division between:

• qualifying new assets, which may benefit from accelerated relief
• leased assets, where eligibility for accelerated relief has expanded in some cases
• second hand and longer life assets, where relief is increasingly back loaded.

Understanding where a business sits within this framework is now central to efficient investment planning.

Capital allowance decisions increasingly overlap with commercial structure, sustainability objectives, and long term investment strategy. A holistic review can help determine whether leasing, direct acquisition, or phased investment delivers the most balanced outcome, both commercially and from a tax perspective.
