1991 Property Value for Council Tax Appeal — How to Find It
Every council tax band in England is based on one number: what your property was worth on the open market on 1 April 1991. Not what it's worth today, not what you paid for it in 2019, not what Zoopla says — the hypothetical sale price on a single day over thirty years ago. If you want to challenge your band, finding that figure is where you start.
Why 1991 Matters
When council tax replaced the poll tax in 1993, the Valuation Office Agency assigned every residential property in England to a band (A through H) based on its estimated capital value as of 1 April 1991. England has never revalued since. A new-build completed in 2024 still gets banded based on what it would hypothetically have sold for in 1991.
The eight bands and their 1991 value thresholds:
| Band | 1991 Value |
|---|---|
| A | Up to £40,000 |
| B | £40,001–£52,000 |
| C | £52,001–£68,000 |
| D | £68,001–£88,000 |
| E | £88,001–£120,000 |
| F | £120,001–£160,000 |
| G | £160,001–£320,000 |
| H | Over £320,000 |
If your property's 1991 value falls below the threshold for its current band, you have grounds to challenge.
Method 1: Direct Sale Evidence (1989–1993)
The strongest evidence is an actual sale price for your property — or comparable properties nearby — from the period around 1 April 1991. Land Registry Price Paid Data covers sales from 1995 onward for free, but you may find 1989–1993 records through title deeds, solicitors' completion statements, or local authority records.
If your property sold in 1991 for £48,000 and it's sitting in Band C (£52,001–£68,000), that's direct evidence of over-banding.
Method 2: Indexed Modern Sale Prices
Most properties don't have a convenient 1991 sale. The accepted alternative is to take a more recent sale price and adjust it backwards using a recognised house price index.
How to do it:
- Find the actual sale price and date from Land Registry Price Paid Data (free to search online).
- Use the Nationwide House Price Index Calculator or Halifax equivalent.
- Input the sale price and date, and adjust to Q2 1991 (April 1991).
- Use the regional index, not the national average — house prices moved at very different rates across the country.
Example: A property sold for £230,000 in June 2018 in the East Midlands. The regional Nationwide index shows the East Midlands multiplied roughly 4.8x between 1991 and 2018. Dividing £230,000 by 4.8 gives approximately £48,000 — which falls in Band B, not the Band D it's currently assigned to.
The VOA's presenting officer will scrutinise your indexing methodology at tribunal. Using the wrong regional base or rounding aggressively weakens your case. Show your working and cite the specific index source.

Method 3: Comparable Properties
If you can't find direct sale data for your own home, use sale prices for comparable properties — homes of similar size, type, age, and location. The Valuation Tribunal uses a "tone of the list" approach: if the evidence from similar properties consistently points to a lower band, the tribunal may agree yours is wrong.
The best comparables are on the same street, have the same number of bedrooms, the same construction era, and similar gross external area. Two or three strong comparables in a lower band with documented 1991 values create a pattern the tribunal takes seriously.
What Doesn't Work
Current property values without indexing. A £350,000 house today might have been worth £60,000 in 1991 — you can't just present the current price.
Automated Valuation Models (AVMs). Zoopla, Rightmove, and similar tools generate estimates based on recent market activity. They tell you nothing about 1991 values and carry minimal weight at tribunal.
Estate agent opinions. Unless the agent provides a formal, evidenced retrospective valuation anchored to 1991, the tribunal treats this as opinion, not evidence.
Putting It Together
Your 1991 valuation evidence should show: the source (Land Registry reference, index calculator URL), the raw data (sale price and date), the calculation (indexing method and regional base), and the result (estimated 1991 value and which band that falls into).
Our England Valuation Tribunal Appeal Guide includes a 1991 Valuation Evidence Worksheet that walks through this calculation step by step, plus a Comparable Properties Log for documenting multiple properties' indexed values in the format the tribunal expects.
