UK Council Tax Savings Calculator (2026)

England bands A–H (£–£4k+); Scotland/Wales A–I. Your band is on your council tax bill or at gov.uk/council-tax-bands.

Use the full annual figure (12 months). If you pay over 10 months, multiply your monthly × 10.

Any adult (18+) resident, even if a student or with SMI. The tool handles disregards automatically.

SMI: diagnosed and in receipt of a qualifying benefit. Disability adaptation: property has been physically modified.

Household monthly income AFTER rent/mortgage. For CTR taper calculation.

Each English LA designs its CTR within a national framework. Typical structure: (1) A "minimum liability" — every working-age claimant pays at least some percentage of the bill (0–15%, typically 10%); (2) Income disregard — the first £X of monthly income is ignored; (3) Taper — income above the disregard reduces CTR by 20–25% of the excess. Pensioners have protection — they use the old national scheme which is more generous. The Institute for Fiscal Studies estimates that 1 in 3 eligible households don't claim CTR — it's the most under-claimed means-tested benefit in the UK.

Your band is based on a 1991 valuation (England) or 2003 valuation (Wales). Many homes were banded in rushed 1992 surveys and are in the WRONG band. Challenge via the Valuation Office Agency (England/Wales) or Scottish Assessors (Scotland) — free. Success rates: 33–50% of challenges succeed. Typical saving: £200–£500/year plus backdated refund. The classic test: find a neighbouring identical house with a lower band — that's strong evidence.

Most LAs backdate CTR 1–3 months automatically on request. Some backdate up to 6 months with good cause. Discounts (SPD, SMI) typically backdate to the date of qualifying event (move, diagnosis), subject to evidence. Appeals go via the Valuation Tribunal (free, 2-month window). Evidence requirements are strict — keep everything in writing and screenshot online portal records.

Bereavement: deceased resident removed from "adults counted" — SPD often kicks in for surviving spouse. Care home: if the sole occupant moves into permanent residential care, full exemption for up to 12 months may apply. Empty property: varies by LA — some allow 1-month Class C exemption; many now CHARGE a premium (150–300%) for long-term empty homes. Under renovation: "major repairs" exemption for up to 12 months in some LAs.
