Fresh Freedom of Information requests obtained by the BBC reveal that UK taxpayers have shelled out nearly £150,000 to manage, secure, or scrub three public artworks by Banksy since 2024. What starts as a surprise midnight stencil on public property quickly turns into a massive logistical line item for local councils and government departments.
When an anonymous artist leaves a gift on a historic wall, someone still has to pay for the scaffolding, security guards, and specialized cleaning crews. The new data shows just how fast those invoices pile up across London.
The £85,000 High Court Cleanup
The single biggest bill comes from the Royal Courts of Justice on Fleet Street. On September 9, 2025, a stencil appeared on the exterior wall showing a judge wielding a gavel over a protester holding a blood-splattered sign, right after UK authorities banned activist group Palestine Action.
Because the mural was painted on the Grade II-listed Queen's Building, Her Majesty's Courts and Tribunals Service had a legal mandate to preserve the structure's original character. That mandate turned out to be expensive. According to reports by The Art Newspaper and Artforum, the Ministry of Justice spent over £50,000 on high-tech laser removal to lift the paint without damaging the historic masonry. Add £35,300 for security guards and staff overtime, and the total tab topped £85,000.
Shadow Justice Secretary Nick Timothy publicly called the expenditure outrageous, arguing taxpayers should not foot the bill to clean damage to a national legal symbol. Yet art critic Estelle Lovatt offered another perspective to the BBC, noting that while some people visit Buckingham Palace, others come specifically to see Banksy's work.
Guarding Waterloo Place and Saving the Piranhas
The High Court stencil is not the only piece consuming public funds. In April 2026, Banksy secretly installed a statue at Waterloo Place near Trafalgar Square. The piece featured a figure with a flag wrapped around his head stepping off a plinth, prompting immediate crowds.
Westminster City Council confirmed it spent roughly £60,000 on security barriers, round-the-clock guards, and administrative oversight. Because the sculpture was placed on council land, Westminster became its involuntary legal owner while officials figure out whether to make it permanent.
A smaller tab came from the City of London in August 2024, when Banksy transformed an old glass police sentry box into a glowing piranha fish tank. Removing the box cost £2,200. Instead of hitting the trash heap, the sentry box was stored safely and is scheduled for public display when the London Museum reopens in November.
Vandalism or Free Cultural Capital?
This £150,000 figure sits at the heart of the modern street art paradox. Auction houses regularly sell Banksy canvases for millions, yet municipal councils are legally required to treat uninvited public murals as property damage.

While London councils keep calculating the cost of security tape and laser scrubbers, Banksy has already moved on to the next wall. The rest of us are left watching local governments decide whether to invoice an anonymous phantom or build a fence around him.
