Where to find your home's 1991 value — every free source
The VOA bands you on what your home was worth in 1991 (2003 in Wales). Here's every free, accepted way to find that figure — and the modern estimates that don't count.
Why 1991, not today
Your band reflects what your property would have sold for on 1 April 1991 (England and Scotland) or 1 April 2003 (Wales) — not what it's worth in 2026. That's why a modern Zoopla estimate is worthless as evidence: the VOA explicitly rejects it. What you need is a figure anchored to the valuation date. The good news is you can assemble one for free.
First: the strongest "value" evidence isn't a price at all
Before you hunt for a 1991 figure, know this — the single most persuasive evidence is the bands of comparable homes, free on the VOA site. If six similar neighbours sit a band below you, that already implies your valuation-date value was lower than the VOA recorded. Often you don't need a price at all (see how to find comparables). Use a 1991 price to reinforce the neighbours evidence, not to replace it.
Every England & Wales sale since January 1995.
Regional index back to 1952 — adjust a 1995 sale to 1991.
Local property pages, 1989–1992, often with asking prices.
Long-traders sometimes keep archive sale particulars.
A house-price index on its own isn’t accepted — it has to anchor a real comparable sale.
1. Land Registry Price Paid Data (free, from January 1995)
The Land Registry publishes every property sale in England and Wales since January 1995, free — search for "Land Registry Price Paid Data". It doesn't reach back to 1991, but an early-1995 sale of a comparable home, adjusted back to 1991, gives a defensible estimate.
2. Nationwide House Price Index — the free deflator
Nationwide publishes a regional house-price index going back to 1952, free to download. To estimate a 1991 value from a 1995 sale:
1991 value ≈ 1995 sale price × (1991 regional index ÷ 1995 regional index)
This "deflation" is a recognised technique. Pair the result with the comparable's current band and you have a credible, valuation-date figure. The index on its own, with no real comparable attached, is not accepted — it has to anchor an actual property.
3. The British Newspaper Archive (1989–1992 listings)
For sales before 1995, the British Newspaper Archive holds local newspaper property pages from the early 1990s — frequently with asking prices for homes on your street. It's a paid subscription, but many libraries provide free access, and one relevant listing is worth more than any modern estimate.
4. Long-established local estate agents
Agents who've traded since the early 1990s sometimes keep archive particulars. A polite phone call or email costs nothing and occasionally turns up a genuine 1991 sale sheet for a comparable.
What the VOA will NOT accept
- Rightmove / Zoopla / Nethouseprices "estimates" — modern automated valuations, explicitly rejected.
- A house-price index quoted on its own.
- Your own purchase price (unless it happens to be a pre-1995 comparable sale).
- The cost of recent work.
The full list is in what evidence the VOA accepts.
Map your figure to a band
Once you have a valuation-date estimate, check which band it falls into — England and Scotland thresholds are in bands explained; Welsh 2003 thresholds are in the Wales guide. If your estimate sits a band below your current one, that's your case.
Free vs the £39 pack
Every source above is free, and the method is genuinely doable in an afternoon. Our £39 pack does the same work — it models the valuation-date figure for your property and assembles the comparable evidence — in about 90 seconds, if you'd rather not. Either way, start with the free check.
