From 1 April 2026, the UK Aggregates Levy will no longer apply in Scotland. Regulations made under section 18 of the Scotland Act 2016 set the appointed day, clearing the way for a Scottish tax on aggregate commercially exploited in Scotland from the same date, as confirmed by the Scottish Government and HMRC.

Revenue Scotland will administer the Scottish Aggregates Tax (SAT) as Scotland’s third fully devolved tax, replacing the UK levy for aggregate produced or used in Scotland. Ministers have set the SAT rate for 2026–27 at £2.16 per tonne, aligned with the UK rate to minimise distortion during the transition. (revenue.scot)

The environmental intent is clear. The UK levy was introduced to reduce virgin extraction and encourage recycled and secondary materials, according to HM Treasury’s own review. The OECD’s 2022 assessment notes mixed evidence: some substitution towards recycled inputs, but overall effects judged limited and in need of better indicators-context that gives Scotland scope to design a more targeted scheme. (gov.uk)

Scotland’s baseline is improving but uneven. SEPA reports an all‑waste recycling rate of 62.3% in 2022 and 62.2% in 2023. Soils and mineral construction waste account for the majority of what is recycled by weight, with around 977,000 tonnes of mineral construction waste recycled in 2023-an indicator of the scale of potential supply of recycled aggregates.

Cross‑border rules have been tightened to avoid arbitrage. HMRC confirms that, from 1 April, aggregate moved from a producer’s site in Scotland into England, Wales or Northern Ireland will be liable to Aggregates Levy in the destination jurisdiction, while SAT applies within Scotland. Parliament’s Finance (No. 2) Bill also confirms the UK levy rate of £2.16 per tonne from the same date. (gov.uk)

Policy levers now sit in Edinburgh. The Scottish Government’s Circular Economy Route Map explicitly proposes using devolved taxes to incentivise recycled aggregates-opening options such as variable rates, targeted credits for high‑quality recycled content, or time‑limited reliefs where haulage distances make reuse viable. Transport matters here: recent life‑cycle work shows that getting aggregate to site can more than double its environmental impact, so local recycling can deliver outsized wins. (gov.scot)

For operators, readiness is everything. Revenue Scotland is onboarding taxpayers, providing webinars and guidance, including on cross‑border transactions. Producers and contractors should complete registration, update invoicing and contracts to reflect the correct regime from 1 April, and refresh specifications so recycled products meet procurement standards and can compete on major jobs. (tax.org.uk)

Public bodies can use the switch to cut material intensity. On some Transport Scotland projects, bid assessments reference recovery of construction and demolition waste and recycled content benchmarks-signals that can grow demand for secondary and recycled materials. Across Great Britain, recycled and secondary materials reached 73.5 million tonnes in 2022, suggesting headroom if specifications enable uptake. (transport.gov.scot)

The data picture will be crucial. The Aggregate Minerals Survey 2023 improves visibility of permitted reserves and inter‑regional flows; Scottish Government analysis points to relatively modest imports from the rest of the UK in 2023. That evidence base will help identify leakage risks and focus the tax where it shifts behaviour most. (gov.uk)

The test now is delivery: can a devolved tax curb quarrying impacts while keeping infrastructure on schedule and on budget? With the UK levy disapplied in Scotland from 1 April and SAT debuting at £2.16 per tonne, the signal to industry is to back high‑quality recycling, shorten supply chains, and verify outcomes with transparent data from Revenue Scotland and SEPA.
