Why 1991 Valuations Can Make Council Tax Unfair

Your council tax band is based on your home's estimated value on 1 April 1991 because this was the last time a nationwide property valuation was conducted in England. [9] This system, now over three decades old, can lead to significant unfairness as property values have changed unevenly since then, a point recently highlighted by local authorities themselves. [17]

What was the 1991 council tax valuation?

When council tax replaced the poll tax in 1993, the government needed to quickly assign a valuation band to every home in England. The Valuation Office Agency (VOA) was tasked with estimating what each of the country's 20-million-plus homes would have sold for on a single day: 1 April 1991. [3]

This was a massive undertaking done at speed. It was not a precise, property-by-property survey. Valuers often made estimates from the roadside or used limited sales data and information on similar properties, a process sometimes called a "second-gear" valuation. [3] This method inevitably introduced errors and approximations from the very beginning.

Properties were then sorted into one of eight bands, from A to H, based on these 1991 value estimates. [1]

Why haven't the bands been updated in England?

A revaluation was planned in England for 2007 but was ultimately cancelled by the government. [3] This was largely due to political sensitivity. When Wales conducted its own revaluation in 2005, around a third of households saw their property move up at least one band, leading to widespread public concern about higher bills. [3]

Fearing a similar backlash, the UK government has repeatedly postponed a revaluation for England. The result is that homeowners are still paying tax based on an assessment that is becoming increasingly disconnected from the present-day reality of the property market.

How do 1991 values create unfairness today?

The link to 1991 values causes two main problems: it embeds historical errors and creates relative unfairness. An initial mistake made in a rushed valuation in 1992 has likely never been corrected unless a homeowner has specifically challenged it. Identical neighbouring houses can be in different bands simply due to a data entry error made over 30 years ago. [13]

More fundamentally, property prices have not increased at the same rate across the country. The value of a flat in a now-gentrified city area may have risen tenfold since 1991, while a large rural house might only have tripled in value. Yet their council tax liabilities haven't changed to reflect this, making the tax regressive. [14]

This means council tax is often a lower percentage of property value for higher-value homes. A Band H property is worth at least eight times a Band A property, but the tax is only three times higher. [14]

What are local authorities saying about the system?

Councils themselves are increasingly highlighting the system's flaws. In submissions for the government's Autumn Budget in late 2026, the Local Government Association (LGA), which represents councils in England, called for a deep reform of the council funding system, explicitly including a review of council tax. [8] This follows earlier calls where the LGA noted that income is unrelated to need, partly because it is linked to outdated 1991 property values. [17]

The core argument is that the system is no longer fit for purpose. Relying on 1991 values creates bizarre outcomes and fails to reflect the modern distribution of property wealth, undermining public confidence in the fairness of the tax. [17]

Does an old valuation mean my band is wrong?

Yes, the age of the valuation is a primary reason why so many properties in England are in the wrong council tax band. The original valuation was approximate, and no mechanism has ever existed to automatically correct errors. [3] If your home is in a higher band than identical properties on your street, it is a strong indicator that the original 1991 assessment was incorrect.

While you cannot appeal simply because the system feels unfair, you absolutely can appeal if the 1991 valuation applied to your specific home was wrong. The entire system for challenging a band is based on proving that the original valuation was flawed when compared to similar neighbouring properties at that time. [5, 12]

How do I challenge a band based on a 1991 value?

You can formally challenge your band via the Valuation Office Agency's 'Check, Challenge, Appeal' process. [2]

• Check: You start by asking the VOA to review the facts it holds on your property (such as its size or age). At this stage, you should gather evidence, including the bands of nearby, identical homes.
• Challenge: If the Check doesn't resolve the issue, you can submit a formal Challenge. Here, you must provide evidence showing your property's 1991 value was incorrect. This evidence should consist of sales prices for comparable properties between 1989 and 1993. [12]
• Appeal: If your Challenge is unsuccessful, you have the right to take your case to the independent Valuation Tribunal for England, which is a free process. [11]

Successfully challenging your band depends on providing the right kind of historical evidence. Arguing about your home's current value or the general unfairness of the system will not succeed. The focus must be on proving the 1991 valuation was wrong from the start.
