This is the regulation 13 limb alone, not the statutory minimum a worker actually receives.",

      "note": "Counted per leave year, and the leave year is the worker's own: regulation 13(3) fixes it by a relevant agreement or, failing that, by the anniversary of the date the employment began. Regulation 13(A1), inserted with effect from 1 January 2024 by SI 2023/1426 reg 3(3)(a), then confines regulation 13 to leave years beginning before 1 April 2024 and, for leave years beginning on or after that date, to workers to whom regulation 15B does not apply — irregular hours and part-year workers accrue under regulation 15B instead. SI 2001/3256 substituted paragraph (1) and came into force on 25 October 2001 by its own regulation 1(1) (\"shall come into force on 25th October 2001\"), which is the date this record carries.",

    "scope_note": "Four weeks is what REGULATION 13 states, and it is not the statutory minimum. Regulation 13A(2)(e) adds a further 1.6 weeks of additional leave in any leave year beginning on or after 1 April 2009, and the familiar 5.6 weeks is those two pots added together — arithmetic, so it is a D14 derivation and a separate record, never this one. Regulation 13A(3)'s 28-day cap on the aggregate is a third figure. The OVERVIEW of GOV.UK's holiday guide states only the 5.6 total and would corroborate neither pot; the sentence registered here is from the same guide's Holiday pay part, which is where GOV.UK separates the 4 weeks from the 1.6 — and it is registered for the 4, not for the pay rate the sentence is about.",
    "notes": "An SI carry (ADR-0014): SI 2001/3256 reg 2(2) substituted paragraph (1) WHOLE (\"The following paragraph shall be substituted for paragraph (1)\"), so there is no value-level substitution for NF-1 to re-derive and the new paragraph carries no provision id in the amender's as-made document. The evidence is the pair: the 1998 Regulations' current view and SI 2001/3256 as made, both hashed and recomputed at Gate 2. Note what the probe is and is not saying — regulation 13 has been amended repeatedly since 2001 (paragraph (2) omitted, (A1) inserted, (14) to (18) added), but nothing has touched paragraph (1) itself, which is the provision this value sits in. One value only: the amending instrument's own explanatory note records that it also revoked the provisions limiting the entitlement to workers continuously employed for thirteen weeks and the spent provisions for leave years beginning before 23 November 1999, so there is history here — and it waits for a parser that can read a block substitution.",
