PRACTICE NOTES
UK Aggregates Levy: definitions, exemptions, compliance, rates and reliefs; key case law; devolution to Scottish Aggregates Tax and cross-border treatment from 1 April 2026
What is the aggregates levy?
HMRC administers an environmental tax, the aggregates levy, on the commercial exploitation of aggregates across the UK.
When does the levy apply?
The levy becomes chargeable when both conditions below are satisfied:
there is a taxable aggregate, and
that aggregate is commercially exploited within the UK
There are pending amendments to Finance Act 2001, s 16(2) to substitute ‘the United Kingdom’ with ‘England, Wales or Northern Ireland’ under Scotland Act 2016, s 18(3). The Act received Royal Assent on 23 March 2016, but the commencement date has not yet been appointed, and it is expected to change in line with the introduction of Scottish Aggregates Tax from 1 April 2026.
