Primary source only Act of Parliament Great Britain in force since 2026-04-07

Checked against its sources: statute verified 2026-09-21

Scope: Part 5 of the Employment Rights Act 2025 replaced the notice-of-underpayment regime in NMWA 1998 ss.19-19H from 7 April 2026 (Sch 10 para 23; SI 2026/323 reg 4), with the Secretary of State — the Fair Work Agency — as enforcer. The 50% reduction for paying within 14 days is s.108. No GOV.UK page states this figure, so the record has no guidance source and is single_source_A by design.
