If you suspect you may be overpaying Council Tax, consumer experts from Which? have provided guidance for all UK residents on how to verify your band – and potentially reduce costs.
The average Band D Council Tax set by local authorities in England for the 2026-27 year is £2,392, while annual fees range from £1,595 (Band A) to £4,785 (Band H). “Your Council Tax is based on what your home was worth all the way back in 1991,” they explained in a TikTok video. “That’s the year [action sci-fi film] Terminator 2 came out, but that valuation has barely changed since.”
Which? highlighted that Council Tax differs depending upon your location – with Wales conducting fresh valuations in 2003 and Scotland operating its own separate system.
In England, Band A encompasses properties valued up to £40,000 at 1991 prices, while Band H represents anything exceeding £320,000 in the same year. The average – Band D – corresponds to homes valued between £68,000 and £88,000 in 1991.
“Most people don’t know if their home is actually in the right band,” Which? continued.
How to check your Council Tax band:
The consumer experts’ first piece of advice is to check what band your neighbours are in, by heading to 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 what comparable properties in your street have recently sold for, the advice continued.
This can be done by visiting Zoopla’s House Price Calculator. “Here you can get an estimate of what your house would have been worth back in 1991,” Which? added.
They went on to warn you should always be “careful” when challenging your Council Tax band.
“It is not guaranteed to save you money,” Which? advised. “Your band could stay the same, it could go down, or it could also go up – and it could affect your neighbours’ bands too.”
Should the outcome prove favourable – i.e. you have been placed in the wrong band for a number of years – you may be entitled to a refund of any overpayments, backdated to when you first moved into the property.
Which? added: “In fact, our survey found that around half of people who challenged their band successfully got it lowered. While only one per cent saw an increase.”
So where can you dispute your banding? Which? recommends England Wales residents visit the Valuation Office Agency website. Those living north of the border should contact the Scottish Assessors Association instead.
