A council in south London has been cautioned by the UK’s statistics authority over claims regarding local tax rates. Wandsworth Borough Council, led by Labour since 2022, has stated in recent public materials that it has frozen council tax bills for four consecutive years.
However, the UK Statistics Authority (UKSA) has expressed concerns that this claim could mislead local residents, after noting increases in separate tax components such as the social care precept and Greater London Authority (GLA) charges.
The council is now reconsidering its communication approach following UKSA feedback, ahead of a forthcoming local election.
UKSA raises concerns over council tax statements
The UK Statistics Authority issued a formal letter to Wandsworth Council after reviewing statements made in videos, leaflets and press releases.
Interim chair Penny Young stated that the council’s assertion of a four-year council tax freeze ‘does not meet the Standard for the Public Use of Statistics, Data and Wider Analysis’.
According to the UKSA, public interpretation of the word ‘frozen’ typically applies to the total tax bill received by residents, not just the main element.
The UKSA found that certain elements increasing council tax, such as the social care precept and GLA components, were not referenced clearly enough in promotional materials. This omission, it said, could cause residents to misunderstand the actual changes to their council tax.
Details of Wandsworth’s tax changes
Since Labour took control in 2022, Wandsworth Council has not raised its general council tax rates. However, the adult social care precept an additional charge ring-fenced for social care rose by 2 per cent in the most recent financial year.
Separately, the Greater London Authority, which sets a precept for all London boroughs, also raised its share of the tax. These increases mean that overall council tax bills did rise for Wandsworth residents, despite the headline rate remaining unchanged.
The average band D council tax bill in Wandsworth stands at £990.07 for the current year and is set to increase to £1,020.35 in the 2026-27 financial year, according to official figures.
Political context and opposition response
The controversy comes amid heightened political competition in Wandsworth, where a council election is scheduled for 7 May. Labour ended several decades of Conservative leadership when it gained control two years ago, and the Conservatives are aiming to regain their former stronghold.
Senior Conservative figures and former council leaders, Lord Udny-Lister and Sir Paul Beresford, raised the issue formally with the UKSA.
In their correspondence, they argued the council’s messaging did not reflect the actual tax increases stemming from social care and GLA charges, making the ‘freeze’ claim inaccurate from the perspective of residents’ bills.
UKSA standards for public communication
Under the UKSA's Code of Practice, public bodies must ensure clarity and transparency in the presentation of statistics. Penny Young cited the ‘supporting understanding’ standard, noting that claims should be presented with adequate context.
The UKSA explained that people would reasonably interpret a claim of ‘frozen council tax’ as referring to their final bill and called for greater precision in future communications.
According to the UKSA’s guidance, clear distinctions must be made between individual elements of the tax and their impact on the total amount paid by households.
Council’s approach to communication
In response to the UKSA’s feedback, Wandsworth Council issued a statement acknowledging the need for clear communication in a complex information environment.
A spokesperson said the council had reviewed the UKSA’s comments and would ‘reflect on the UK Statistics Authority’s observations and take forward any learning in future communications’.
The council noted that it has tried to clarify in public communications that only the main element of council tax is frozen, though both short and long-form materials are in use to reach different segments of residents.
The statement emphasised a continued commitment to accessible information for the borough’s diverse population.
Final Summary
The UK Statistics Authority’s warning to Wandsworth Council brings renewed attention to the way local tax information is communicated to the public.
As other authorities monitor the situation, the case highlights the importance of full context and accuracy, particularly during election periods. Residents are left to assess council statements in light of official guidance on clarity and transparency.
