Banksy Removal Cost: £85,300 to Erase One Mural

Q: How much did it cost to remove the Banksy from the Royal Courts of Justice?

£85,300 so far. Figures released to the BBC under Freedom of Information requests in August 2026 show roughly £50,000 spent on removing the paint and £35,300 on security and staff overtime. The first cleaning attempts failed, so contractors moved to laser technology. The bill is not final: Westminster City Council still has to inspect the wall, and if the removal is judged incomplete the affected stonework may have to be cut out and replaced.

Q: Who owns a Banksy painted on someone else's wall?

In practice, whoever owns the wall. There is no separate title in the image, so a building owner can legally scrub it, sell it or cut it out of the masonry. The catch is authentication: Banksy's handling body Pest Control has consistently declined to authenticate street works that have been removed from their original locations, which is why murals prised off walls tend to sell for far less than studio canvases, and often struggle to sell at all.

Q: Why was the Royal Courts of Justice mural destroyed instead of preserved?

Because of heritage law rather than an opinion about the art. The Queen's Building, completed in 1968, is Grade II listed, and HM Courts and Tribunals Service said it was obliged to maintain the building's original character. Listing protects the fabric of a structure as it was designated, which means an unauthorised addition — however famous the person who added it — is legally a defect to be reversed, not an asset to be kept.

Here is a sentence that should not be possible: the British state spent more money getting rid of a free painting than most people will ever spend on a house deposit.

On 8 September 2025, a stencil appeared on the Carey Street wall of the Royal Courts of Justice in London. A judge in full wig and robe, bringing a gavel down on a protester lying flat on the ground. One splash of red on the protester's placard — the only colour in the whole thing. Banksy confirmed it on Instagram with three words: "Royal Courts of Justice: London." It collected over 1.5 million likes within days.

It was gone in two.

What we did not know until this week is what that erasure actually cost. Figures released to the BBC under Freedom of Information requests, and reported by The Art Newspaper on 10 August 2026, put the running total at £85,300.

The bill, itemised

It breaks down like this:

£50,000 — attempting to remove the paint from the Grade II-listed stonework
£35,300 — security and staff overtime while the work was covered and guarded

The detail that turns this from a news item into a comedy is how they did it. The first attempts to scrub the paint off did not work. Portland stone is porous; a stencil sprayed onto it does not sit on the surface so much as move in. So contractors escalated to laser technology — the same conservation-grade kit normally used to lift centuries of soot off cathedral carvings, deployed here in the opposite direction, to un-make a picture that was eleven months old.

And it still is not finished. Westminster City Council has to inspect the wall. If the clean is judged incomplete, another method gets tried. And the option of last resort, according to the reporting, is to cut the affected stonework out and replace it. Which is to say: the plan for saving the historic building's original fabric may end with removing the historic building's original fabric.

Somewhere in a government spreadsheet there is a line item for lasers, and its purpose is subtraction.

Three Banksys, three completely different verdicts

The same BBC investigation found that three recent Banksy works have cost the public purse close to £150,000 in total. What makes that number interesting is not its size. It is that the money went in three totally opposite directions.

August 2024 — the piranhas. Banksy painted the glass of a City of London police sentry box on Ludgate Hill so that it appeared to be a fish tank full of piranhas. Cost to remove it: £2,200. The City moved the whole box to Guildhall Yard, then gifted it to the London Museum for permanent display. A piece of street furniture became a museum object for roughly the price of a second-hand car.

April 2026 — the statue. A figure in a suit steps off a plinth in Waterloo Place, carrying a flag that has wrapped across his own face so he cannot see where he is going. Westminster City Council spent close to £60,000 on barriers, security and administration — not to remove it, but to keep it safe. The council called it a striking addition to the city's public art scene, and is deciding by the end of this summer whether to make it permanent.

September 2025 — the judge. £85,300 and lasers.

Same country. Same artist. Same eighteen-month window. One work gets a museum, one gets a fence, one gets destroyed. If you are looking for the aesthetic principle that separates them, do not bother. There isn't one.

What actually decided it

The official reason is heritage law, and — irritatingly for anyone who wants a villain — it is a real reason, not a cover story.

The Queen's Building, completed in 1968 and part of the 143-year-old Royal Courts complex, is Grade II listed. HM Courts and Tribunals Service said it is "obliged to maintain its original character." Listing freezes a building's protected fabric as designated. Under that framework an unauthorised addition is not a bonus feature. It is legally a defect, and the duty runs toward reversal regardless of who made it or what it would fetch.

So the Ministry of Justice was not standing in a room deciding whether Banksy is any good. It was following a rule that was written long before anyone imagined the rule would ever be pointed at an artwork the public actually wanted.

Which is exactly why the outcome feels so arbitrary. The piranha box was not listed — it was a 1990s security booth, part of the City's "ring of steel." Moveable, unprotected, therefore saveable. The statue stands on public highway rather than on protected fabric. The judge landed on the one surface in the sequence that came with a legal obligation to un-paint it. The deciding factor was not artistic merit or public feeling. It was what the paint landed on.

There is a version of this story where that is reassuring: rules applied without fear or favour. There is another version where a state spent £85,300 removing a picture that criticised that state, eleven months after it appeared two days after around 890 arrests at a London protest, and the paperwork happened to make that mandatory. Both versions are supported by the same facts. That ambiguity is doing a great deal of work for everybody involved.

What the wall was worth

The gallery owner John Brandler — who knows the market as well as anyone, having bought Banksy murals off actual buildings — put the Royal Courts piece at around £5 million.

Treat that as a headline rather than a valuation, because a wall is not a canvas. But the ballpark is not fantasy. Banksy's auction record is £18.5 million, set at Sotheby's in October 2021 for Love Is in the Bin, the half-shredded remains of Girl with Balloon — a work whose value was created by partially destroying it, which is a joke that has aged into an economic law. Before that the record was £9.9 million for Devolved Parliament in October 2019.

Street works do worse, and there is a specific reason. Banksy's handling body, Pest Control, has consistently refused to authenticate murals removed from their original sites. No authentication, no clean sale. Slave Labour, prised off a Wood Green wall in 2013, was expected to fetch up to £450,000 at auction. Season's Greetings, which appeared on a garage in Port Talbot in 2018, sold to Brandler for a six-figure sum and has since been shuttled around the country like awkward furniture.

So the honest number for the Carey Street wall is not £5 million. It is: somewhere between a few hundred thousand and nothing, depending on whether anyone would touch it. Which is still a strange thing to spend £85,300 aiming lasers at. As we've noted before, the gap between an artwork's price and its meaning can run in either direction — and here it ran in both at once.

Who owns a picture painted on your wall?

Legally, you do, in the sense that nobody else does. There is no separate ownership of the image sitting on top of your bricks. You can paint over it, sell the wall, or hire someone to saw it out.

Practically, you own a problem. The moment a mural comes off its wall it loses the thing that made it valuable — the site, the joke, the specific building it was arguing with. A judge beating a protester is a devastating image on a courthouse. In a collector's hallway it is a print of a man in a wig. The context around a work does as much labour as the marks themselves, and removal deletes exactly the half you cannot re-buy.

This is also why Banksy murals attract thieves with such reliability — the City moved the piranha box to Guildhall specifically because unattended Banksys have a habit of vanishing. It is a much lower-effort crime than the museum heists that keep succeeding in France, and unlike a stolen Vermeer, the loot arrives with a plausible story about who it belongs to.

Some honest limits

£85,300 is not final, in either direction. It is a running total from FOI figures and could rise substantially if the stonework has to be replaced. It is also not a like-for-like "cost of destroying art" — a large share is security and overtime, which the building would arguably have incurred simply from the crowds, whether or not it ever scrubbed the wall.

The £5 million figure is one dealer's opinion. No unauthenticated removed mural has ever come close to that at open auction. Treat it as an indication of attention, not of price.

Preservation is not automatically the right answer. "Keep every Banksy" sounds obvious until you notice it means unauthorised painting is fine if you are famous enough, which is a rule that only works for one person. The council that fences off a Banksy this month is the council that prosecutes a nineteen-year-old for a tag next month. The inconsistency is not really about lasers. It is about celebrity, and it cuts both ways.

The bit that stays with you

The removal did not fully work. The reporting describes a residual, ghostly impression left on the stone where the image used to be.

So the Ministry of Justice spent £50,000 on paint removal, £35,300 on guarding the site, escalated to laser technology, and produced — on the wall of a court — a faint outline of a judge hitting someone, which is now harder to remove than the original and considerably harder to explain. The state has, at enormous expense, made a permanent artwork out of trying not to have one.

Banksy has never had to say a word about it. He does not need to. That is the whole trick and it always has been: the work is not the stencil, it is what the institutions do next. Paint a judge on a courthouse and the courthouse will spend six figures composing your sequel.

The £2,200 piranhas are going in a museum. The £85,300 judge is a smudge that will not leave. Somewhere in that difference is everything Britain currently thinks about art, and none of it was decided by anyone who looked at either picture.

Quick questions

How much did it cost to remove the Banksy from the Royal Courts of Justice? £85,300 so far — roughly £50,000 on paint removal and £35,300 on security and overtime, per FOI figures released to the BBC in August 2026. Initial scrubbing failed, so contractors moved to laser technology. The total is not final: if Westminster City Council judges the clean incomplete, the stonework itself may have to be cut out and replaced.

Who owns a Banksy painted on someone else's wall? Whoever owns the wall. There is no separate title in the image, so an owner can scrub it, sell it or cut it out. The complication is authentication — Pest Control, Banksy's handling body, has consistently declined to authenticate street works removed from their original locations, which is why prised-off murals sell far below studio canvases and frequently do not sell at all.

Why was it destroyed instead of preserved? Heritage law, not aesthetics. The Queen's Building (1968) is Grade II listed and HMCTS said it is obliged to maintain the building's original character. Listing protects the fabric as designated, so an unauthorised addition counts legally as a defect to reverse — however famous its author. The two other recent Banksys landed on unprotected surfaces, which is the real reason they survived.

How we sourced this

Cost figures — £85,300 total, split roughly £50,000 for paint removal and £35,300 for security and overtime, plus a combined total near £150,000 across three works — were obtained by the BBC under Freedom of Information requests and reported on 10 August 2026 by The Art Newspaper and FAD Magazine. Details of the mural's appearance on 8 September 2025, its removal over the following two days, the Grade II listed status of the Queen's Building and the residual outline left on the stone are drawn from that reporting and contemporaneous coverage including Al Jazeera and PBS NewsHour. The piranha sentry box acquisition is confirmed by the City of London Corporation's own announcement. The Waterloo Place statue costs and the pending permanence decision come from Westminster City Council statements to the BBC and The Art Newspaper on 28 July 2026. Auction records — £18.5m for Love Is in the Bin (Sotheby's, October 2021) and £9.9m for Devolved Parliament (Sotheby's, October 2019) — are the published hammer-inclusive results. The circa £5 million valuation is gallery owner John Brandler's stated opinion and is not a transacted price; no removed, unauthenticated Banksy mural has publicly sold anywhere near it. Published 10 August 2026.
