2025-26 legacy carer premium and HB personal allowance are extrapolated, not statutory #2110
Description
Found while landing #1992.
Several legacy-benefit applicable amounts carry a 2025-04-01 value that looks like a CPI extrapolation of 2024-25, not the statutory 2025-26 rate. Neither entry below has a reference:
parameters/gov/dwp/carer_premium/single.yaml: 2025-04-01 is 46.38. The statutory 2025-26 carer premium was £46.40.parameters/gov/dwp/housing_benefit/allowances/single/older.yaml: 2025-04-01 is 92.04. The statutory 2025-26 personal allowance (single, 25 or over) was £92.05.
Evidence. The Council Tax Reduction (Miscellaneous Amendment) (Scotland) Regulations 2026 (SSI 2026/56) substitutes "£92.05" with "£95.55" and "£46.40" with "£48.15" in SSI 2021/249 and SSI 2012/319, which mirror the DWP amounts. The text was fetched from legislation.gov.uk on 2026-10-02.
To do.
- Check every legacy applicable-amount parameter that has a 2025-04-01 entry against the Social Security Benefits Up-rating Order 2025 (SI 2025/295): HB, HB (SPC), IS, JSA and ESA personal allowances and premiums.
- Correct each wrong value, with a reference.
- Update the YAML expectations that used the extrapolated values. For example, Count Carer Support Payment as Council Tax Reduction income #1992's 2025 CTR case gives 1,173.25 with 92.04/46.38 and 1,173.56 with 92.05/46.40.
- Run a real Enhanced FRS impact.
