Important Disclaimer
This is an estimate only, based on regional house price index data. Actual 1991 property values depend on many factors including property size, condition at the time, and local market conditions. For a definitive assessment, compare with neighbours' bands and consult official VOA records. This tool is for informational purposes only.
How does this calculator work?
We use historical house price index data from Nationwide and regional growth patterns to estimate what your property would have been worth on 1st April 1991 — the date all council tax bands are based on.
Property prices have grown significantly since 1991, but growth varies hugely by region. London properties are now worth around 5x their 1991 value, while properties in the North are typically worth 2.5-3x their 1991 value.
Property Type Matters
Detached houses have typically seen higher price growth than flats, so we adjust our estimate based on your property type.
Location is Key
A house in London has grown ~5x since 1991, while the same house in the North East may only be 2.5x higher.
UK Average: 3.5x
On average, UK properties are worth about 3.5 times more now than in 1991, but your region may differ significantly.
