Regulation 16(3ZD), inserted from 1 January 2024, states the SAME 52 weeks as the \"relevant period\" over which the regulation 16(3ZA) payment types (commission, status and regular-overtime payments) are averaged for regulation 13 and 15B leave; it is the same figure, not a second one.",

SI 2018/1378 inserted regulation 16(3)(e) and (f) and came into force on 6 April 2020 by its own regulation 1 (\"come into force on 6th April 2020\"), which is the date this record carries; nothing in the instrument confines the insertion to a later leave year. Where sections 223(2) or 224(3) apply, sub-paragraph (f) stops the count at 104 weeks back and takes the weeks of which account is taken.",

For the regulation 16(3ZA) payment types on regulation 13 and 15B leave, regulation 16(3ZD) states the same 52 weeks as the \"relevant period\" ending with the last complete week before the calculation date, with weeks in which no remuneration was payable or the worker was on sick or statutory leave discounted and earlier weeks brought in (reg 16(3ZE) and (3ZF)), back to a 104-week backstop (reg 16(3ZG)) that mirrors sub-paragraph (f)(i).

The evidence is the pair: the 1998 Regulations' current view and SI 2018/1378 as made, both hashed and recomputed at Gate 2. Pinned (D20) to regulation 16(3)(e), the smallest provision the probe can name that carries both tokens: the modification clause is (e)'s own text and the 52 is its item (ii), which the current view numbers regulation 16(3)(e)(ii) but which sits below the sub-paragraph grain the probe pins; the two locator tokens tell its 52 from (e)(i)'s \"less than 52 complete weeks\" beside it. RE-PINNED 2026-09-15 from regulation 16(3ZD) at 1 January 2024 (SI 2023/1426): s.224 was never amended — WTR reg 16(3)(e) carries the 52 — and (3ZD) is the \"relevant period\" for the reg 16(3ZA) payment types only, so the base 52-week averaging has stood in (e)(ii) since 6 April 2020 and the archived current view carries no later note on it. A provision move for the SAME concept, the 52-week reference period, so the id is kept under ADR-0012's identity rule (a definition change is a new id; a better citation for an unchanged definition is not). ONE value only: the twelve weeks before 6 April 2020 were the Act's own and are not this instrument's history.",
