Definition

The UK Modern Slavery Act 2015 is UK legislation that consolidates offences of slavery, servitude, forced labour and human trafficking, establishes an Independent Anti-Slavery Commissioner, and under section 54 requires commercial organisations above a turnover threshold to publish an annual statement describing steps taken to ensure slavery is not occurring in their business or supply chains.

Overview

What it means

It created the transparency-statement model that influenced similar laws in Australia and elsewhere, though its reporting duty carries no financial penalty for non-compliance.

How it is used

Companies publish modern slavery statements on their websites; investors and NGOs benchmark statement quality; reform debates push for mandatory due diligence.

Why it matters

It was the first major national modern slavery transparency law and remains the reference point for supply-chain reporting in the UK.
