+Pay the legacy enhanced disability premium for an award of enhanced PIP daily living or armed forces independence payment as well as the highest DLA care rate, and apply its State Pension Credit age limit. Count an award only where its amount is positive, and count an amount entered without its category when it reaches `52 × (top weekly rate − £1)`. Give four working-age Council Tax Reduction schemes their own lists. Scottish councils count attendance allowance at either rate from April 2023, and the Scottish Ministers removed the age limit from June 2022. Merton and Westminster count either PIP daily living rate and omit armed forces independence payment; Newham counts either PIP daily living rate and armed forces independence payment. In Kingston upon Thames the model keeps reading `is_enhanced_disabled_for_benefits`, with no age limit, until it can apply the council's own list.

		Pay the legacy enhanced disability premium for an award of enhanced PIP daily living or armed forces independence payment as well as the highest DLA care rate, and apply its State Pension Credit age limit. Count an award only where its amount is positive, and count an amount entered without its category when it reaches `52 × (top weekly rate − £1)`. Give four working-age Council Tax Reduction schemes their own lists. Scottish councils count attendance allowance at either rate from April 2023, and the Scottish Ministers removed the age limit from June 2022. Merton and Westminster count either PIP daily living rate and omit armed forces independence payment; Newham counts either PIP daily living rate and armed forces independence payment. In Kingston upon Thames the model keeps reading `is_enhanced_disabled_for_benefits`, with no age limit, until it can apply the council's own list.
