Consumer experts from Which? have urged UK households to check their Council Tax band, as many may be overpaying based on outdated property valuations. Council Tax bands in England are still based on 1991 property values, and the average Band D bill for 2026-27 is £2,392, with annual fees ranging from £1,595 (Band A) to £4,785 (Band H).
Why You Might Be Overpaying
In a TikTok video, Which? explained: "Your Council Tax is based on what your home was worth all the way back in 1991. That's the year Terminator 2 came out, but that valuation has barely changed since." They noted that Council Tax differs by location, with Wales using 2003 valuations and Scotland operating its own system.
In England, Band A covers properties valued up to £40,000 in 1991, while Band H includes anything over £320,000. The average Band D corresponds to homes worth between £68,000 and £88,000 in 1991.
How to Check Your Band
Which? recommends first checking what band your neighbours are in via the government's Council Tax band website. "If your home is similar in size, age and location, you should probably be in the same band," they said. Next, research recent sale prices of comparable properties on Zoopla's House Price Calculator to estimate your home's 1991 value.
Challenging Your Band: Risks and Rewards
Which? warns that challenging your band is not guaranteed to save money. "Your band could stay the same, it could go down, or it could also go up - and it could affect your neighbours' bands too." However, their survey found that 54% of those who challenged their band successfully got it lowered, with 34% receiving a rebate. Some got refunds covering more than 10 years, and nearly 20% received up to £500 back.

Changes That Affect Your Band
Your property may be rebanded if you demolish part of it, create self-contained units, split or convert flats, start or stop working from home, or if there are significant local changes like a new road.
If successful, you may be entitled to a refund of overpayments backdated to when you first moved in. Which? added: "Our survey found that around half of people who challenged their band successfully got it lowered, while only one per cent saw an increase."
