PropPulse › Council Tax Banding › Evidence

⚠ Before you file: A challenge can RAISE your band — and your neighbors' bands. If your evidence is weak, do not file. The letter engine requires you to acknowledge this before drafting anything. Read the VOA’s verbatim warning →

What counts as evidence for a council tax band challenge

The answer: Up to 5 comparable properties: same street/estate (≤10 miles rural), same type, same build period, size within ~10% — plus sale prices INSIDE the statutory valuation window.

What the VOA explicitly rejects

VERIFIED VOA guidance: "You should avoid using data from house price calculators as evidence" — the VOA "does not use property price indexes". Indexed/estimated 1991 values NEVER go in the letter; the engine uses band comparison only.

The valuation windows

Sale-price evidence has to fall inside the statutory window for your country: England — Sale-price evidence must come from 1 April 1989 – 31 March 1993. Wales — Sale-price evidence must come from 1 April 2001 – 31 March 2005. Scotland — Sale-price evidence around the 1991 valuation date [flagged: search-grounded, not independently verified].

Why this matters for the letter

PropPulse's document generator only ever cites your comparable-band table and, where you have it, in-window sale prices — never indexed or estimated values. If your only evidence is a house-price-calculator estimate, the honest answer is that it will not move a case; go gather comparable bands instead.
