In the summer of 2025, something remarkable happened at the Old Royal Naval College in Greenwich. A 10,000-capacity electronic music festival moved in. The bass from professional PA systems rippled across the Thames. VIP ticket holders were escorted into the Painted Hall, a 300-year-old baroque masterpiece by Sir James Thornhill, and used it as a backstage lounge. Nitrous oxide canisters were found on site afterward. Over six sold-out dates, 57,000 tickets were sold.
The event was called Labyrinth on the Thames. The venue is a Grade I listed building at the heart of a UNESCO World Heritage Site. And the whole thing happened without planning permission.
That last fact is not speculation. A Greenwich Council planning officer confirmed it on the public record. The council said a planning application did arrive, but too late for a decision before the events took place. They chose not to enforce.
What follows is a forensic account of how a financially desperate charity, a well-connected private promoter, a council that looked the other way, and a conflicted heritage regulator created the conditions for one of the most brazen regulatory failures in recent UK heritage history. And how they plan to do it again, bigger, this summer.
Timeline: How We Got Here
The Charity That Can't Afford to Say No
The Old Royal Naval College is operated by the Greenwich Foundation, a registered charity (No. 1062519). Its charitable objects are simple: preserve the site and educate the public about its historical, architectural, and artistic importance. That's it. Preservation and education.
But the Foundation is broke. In its own written evidence to Parliament, submitted to the DCMS Select Committee, it described its financial position as "precarious." It filed a Serious Incident Report with the Charity Commission over the state of its roofs. It needs an estimated GBP 30 million for roof repairs over the next 10 to 20 years. Another GBP 2 million for Thames foreshore erosion works. Conservation costs run to GBP 1 million a year. Government grants have collapsed to just 5% of income.
In this context, Labyrinth is not a nice-to-have. It is existential. Our analysis estimates the festival contributes GBP 500,000 to GBP 1 million annually to the Foundation. Against a GBP 910,000 deficit in 2025, that revenue is the difference between survival and insolvency.
"There is a ceiling to how much we can balance the commercial income opportunities versus the open nature and utilisation of the site and the impact on its fabric."
The Greenwich Foundation, written evidence to ParliamentFollow the Money: The Corporate Structure
The event operates through a three-entity structure that disperses liability while concentrating commercial benefit. Understanding who sits where, and who controls what, is essential to understanding how accountability evaporates.
Dicks is also DPS on the premises licence. Jannath Rankou (The Fair) acted as licensing agent.
Note the gap: the Greenwich Foundation provides the venue and receives revenue, but is not the licence holder and does not appear on the premises licence. Labyrinth Festivals Ltd holds the licence, but delegates on-site delivery to The Fair. If something goes wrong, who is responsible? The charity says it's the promoter. The promoter says it's the operator. The operator says it's the venue's decision. This is liability by design.

The People Who Made It Happen
Every decision in this chain was made by specific individuals. Here is who they are and what role they played.
The Foundation: Leadership
Chief Executive of Historic England since 2015, the statutory body responsible for protecting England's heritage, including Grade I listed buildings and World Heritage Sites. Simultaneously a trustee of the Greenwich Foundation, the charity operating the very site he is supposed to regulate.
Before Historic England, Wilson was Director of the Greenwich Foundation itself, named in the Maritime Greenwich WHS Management Plan (2014) as a former Foundation Director. He personally oversaw the charity's pivot toward commercial activity. He is the architect of the strategy he is now supposed to independently scrutinise.
The Management Plan (s.4.1.31) requires developments exceeding 1,000 sq.m in the conservation area be notified to Historic England. If Labyrinth infrastructure triggered this threshold, the notification was sent to Wilson's own organisation while he sat on the Foundation's board.
Announced retirement from Historic England in October 2024. Current status in both roles unconfirmed.
Former CEO of the National Council for Voluntary Organisations (NCVO) from 1994 to 2019. Knighted 2010. Currently chairs The Oversight Trust and NatCen. He is the UK's most prominent charity governance figure.
As Chair, he bears ultimate governance responsibility for the Foundation's decision to host mass commercial electronic music festivals on a Grade I listed UNESCO World Heritage Site, for the Duncan Wilson conflict of interest on his watch, and for the planning permission failures of 2025. His personal reputation as the country's leading authority on charity governance is directly at stake.
Joined February 2019 as Director of Finance & IT. Interim CEO from October 2019, permanent from March 2020. Background: 25+ years in commercial real estate and not-for-profit. Previous roles: Finance Director of a multi-site hospitality business (20+ heritage pubs, bars, boutique hotels); Director of Finance at a private-equity backed flexible office provider. Oxford Strategic Leadership Programme (Said Business School).
His background is explicitly commercial hospitality, not heritage or conservation. He was recruited to monetise the site. Under his leadership, the Foundation partnered with Labyrinth, proceeded without planning permission, and ran consecutive deficits totalling GBP 2.2 million while telling Parliament the charity is in a "financially precarious position."
Joined April 2020. Previous: Head of Operations at the Royal Academy of Dramatic Art (RADA), overseeing front-of-house, box office, venue hire, events. 10+ years in arts and events.
She is the operational decision-maker for commercial events at ORNC, including the Labyrinth partnership. Day-to-day commercial decisions, venue hire negotiations, and the relationship with the promoter run through her role.
Joined 2014. 20+ years charity finance experience. Oversees financial reporting and statutory accounts. Responsible for the financial reporting that shows consecutive deficits of GBP 1.31m (FY2024) and GBP 910k (FY2025) despite growing commercial income.
The Foundation: Trustees
Manages a GBP 50 billion annual budget at the MOD. Simultaneously a trustee (and likely finance committee member) of the Greenwich Foundation. ORNC was a Royal Navy institution transferred to the Foundation in 1998 under government terms. A serving MOD official overseeing finances at a charity whose lease involves MOD/government commitments creates a structural tension, particularly if the terms of transfer are examined.
Responsible for commercial events across the Tower of London, Hampton Court Palace, Kensington Palace, Banqueting House, Kew Palace, and Hillsborough Castle. Her appointment to the ORNC board was not accidental; it reflects a deliberate decision to professionalise the charity's events operation.
Historic Royal Palaces does not permit 10,000-capacity open-air electronic music festivals at the Tower of London or Hampton Court. The events expert on the ORNC board is presiding over activities her own organisation would never allow at its sites.
25 years in entertainment marketing: LEGO, Guinness World Records, Jeff Wayne's War of the Worlds Immersive Experience. Another board appointment that reinforces commercial entertainment strategy rather than heritage preservation. Her presence signals that the board is oriented toward revenue generation, not conservation.
Led the Painted Hall conservation project at ORNC. Trustee of the Georgian Group. The Painted Hall he painstakingly restored, a 300-year-old baroque masterpiece by Sir James Thornhill, is now being used as a VIP backstage lounge for festival ticket holders paying premium prices. His conservation work is being directly undermined by the commercial events he, as a trustee, has approved.
35-year Royal Navy career. Former Governor of Gibraltar. The naval heritage connection to ORNC is central to the charity's stated mission of preservation. As a trustee, he has oversight responsibility for what happens at a site built to serve the Royal Navy.
Founding Director of Urban Space Management. Active in urban regeneration since the 1970s. A development and commercial background, further reinforcing the board's tilt away from heritage conservation.
Conservation Architect. Chairman at Purcell, the UK's leading heritage architecture firm. Led projects at the National Portrait Gallery and V&A. Provides heritage conservation credibility to the board. The question is whether that credibility has been used to challenge or to legitimise the events programme.
Director of Development at Tate. 20 years in cultural fundraising. Her expertise is in generating revenue for arts organisations. Another appointment consistent with a commercially focused board.
Former Chief People Officer at the John Lewis Partnership. People and operations background.
The Promoter: Labyrinth
Full name: Nicholas Michael Twycross Castleman (b. December 1993). University of Bristol. Co-ran Binary Vision (D&B night) in Bristol. Founded Labyrinth 2017 as a Thursday club night at Notting Hill Arts Club. Co-founded Labyrinth Records 2021.
His relative Christopher Norman Anthony Castleman (b. 1941) was a director of Standard Chartered PLC, Standard Chartered Bank, and Standard Chartered Holdings Limited from 1991 to 2006, with a historical correspondence address at Tofte Manor, Sharnbrook, Bedfordshire. Suzy Castleman operates Tofte Manor as a retreat centre; Labyrinth runs its "Open Air" festivals there. The family monetises its own estate through the same brand.
Director of 35 Tamworth Street Limited (property holding company) until 3 February 2025, when he resigned and was replaced the same day by his mother, Susan Mary Castleman. His personal address: Flat 3, 35 Tamworth Street, London SW6, the property held by that company.
Michael Edward Dicks (b. December 1994). Previous: Cain International (real estate private equity), PwC. ICAEW qualified (2017-2020). Address: Flat 6, Parkgate House, 40 Parkgate Road, London SW11 4NT.
He bridges the promoting company and the regulatory framework in a single person: director of Labyrinth Festivals Ltd (the licence holder) and the Designated Premises Supervisor on the ORNC premises licence (No. 18546). Personal licence issued by London Borough of Lambeth. He signed the premises licence application. Contact email on application: mikey@labyrinthevents.com.
The Event Operator: The Fair
Runs the event production company that delivers Labyrinth on the Thames on the ground. The Fair sits between the promoter (Labyrinth) and the venue (Greenwich Foundation) in the operational chain. His company handles on-site event delivery while Labyrinth retains commercial control and the Foundation provides the venue. This three-entity structure disperses operational liability.
Works for The Fair. Named as Agent on Premises Licence No. 18546 (Application 22665). She acted as the formal representative in the licensing process on behalf of Labyrinth Festivals Ltd, bridging The Fair's operational role and the regulatory framework.
Legal
Acted as licensing solicitor for Labyrinth Festivals Ltd on the ORNC premises licence application. Negotiated licence conditions with the Royal Borough of Greenwich. Confirmed agreement to conditions on behalf of Labyrinth via email to Daniel Bygrave and Chris Devine at RBG on 21 October 2025.
The Council That Looked the Other Way
The Royal Borough of Greenwich has its own questions to answer. A council planning officer confirmed on the public record that no planning permission was obtained for the 2025 Labyrinth events. The council then chose not to take enforcement action, noting that a premises licence was in place.
But a premises licence is not planning permission. The Licensing Act 2003 and the Town and Country Planning Act 1990 are entirely separate legal regimes. A premises licence authorises licensable activities. It does not and cannot authorise development. The council's own officer acknowledged the planning application arrived too late. The events proceeded anyway. The council knew. And it did nothing.
Under Section 172 of the TCPA 1990, the council has the power to issue enforcement notices where there has been a breach of planning control. It chose not to exercise that power. That decision is discretionary, and it is now open to challenge by any interested party, via formal enforcement complaint, complaint to the Local Government and Social Care Ombudsman, or judicial review.
The following council officers are named in the licensing correspondence for the 2026 licence application:
Emailed the council's licensing team on 19 September 2025 setting out the noise management conditions to be attached to the Labyrinth premises licence. His email (to Folashade Bonisehi and Chris Devine) outlined the conditions including the 65dB LAeq 15 mins noise limit, measurement points, and post-event reporting requirements. His division encompasses Community Protection (Statutory Nuisance) and Community Safety.
Contact: Daniel.Bygrave@royalgreenwich.gov.uk / 020 8921 8258. 4th Floor, The Woolwich Centre, 35 Wellington Street, London SE18 6HQ.
Named in the licensing correspondence as a recipient of both the council's internal conditions email and the solicitor's agreement to conditions. Chris.Devine@royalgreenwich.gov.uk. His role in the licensing process for the ORNC events is part of the regulatory chain that granted a premises licence while the planning permission question remained unresolved.
Named in the licensing correspondence as a recipient of the conditions email from Daniel Bygrave. Folashade.Bonisehi@royalgreenwich.gov.uk. Part of the licensing team that processed the Labyrinth application.
The broader question for the Royal Borough of Greenwich is institutional. The planning department knew the 2025 events proceeded without permission. The licensing department subsequently granted a new, expanded licence for 2026. These are different departments, but they serve the same council. The left hand knew what the right hand was doing, and neither intervened.
What the Neighbours Say
Residents in the immediate vicinity of the Old Royal Naval College were not consulted before the 2025 events. The licensing process allows for public representations, but the planning process, which requires formal notification of adjacent occupiers, was never completed because the planning application arrived too late. The people who live closest to the site had no formal say.
Reports from local news outlets and public comment forums paint a consistent picture:
The bass was so loud it vibrated the walls of our flat. We couldn't sleep until after midnight. We had no warning it was happening.
I've lived here for 20 years. We accept that the site hosts events. But 10,000 people and a full festival sound system is not a corporate dinner or a graduation ceremony. It's a fundamentally different thing.
The nitrous oxide canisters on the ground the next morning told you everything you need to know about the crowd control.
The 65dB noise limit, now an enforceable licence condition for 2026, was described by one acoustic consultant quoted in local reporting as "ambitious for an outdoor festival with a professional PA system." Whether that limit can realistically be met while delivering the experience Labyrinth is selling — headliners like Moby and Peggy Gou on an outdoor main stage — remains to be seen.
The Painted Hall: A Conservation Case Study
The Painted Hall deserves its own section because it sits at the intersection of every issue in this investigation: heritage protection, commercial exploitation, governance failure, and the gap between what the Foundation says and what it does.
Sir James Thornhill painted the Lower Hall ceiling between 1707 and 1714, and the Upper Hall between 1718 and 1726. It took him 19 years. The work is considered the finest decorative painting in England, the closest British equivalent to the Sistine Chapel. It depicts the triumph of William and Mary, the Protestant succession, and the naval power of the nation.
Between 2016 and 2019, the Painted Hall underwent a GBP 8.5 million conservation project, led by Will Palin (now a Foundation trustee). The conservation team spent years cleaning, consolidating, and restoring the 40,000 square feet of painted surface. Historic England contributed GBP 3.1 million of Heritage Lottery funding to the project. It was one of the most significant heritage conservation efforts in the UK in the last decade.
In 2025, VIP ticket holders at Labyrinth on the Thames were escorted into the Painted Hall and used it as a backstage hospitality area. Premium ticket prices for VIP packages were in the range of GBP 100 to GBP 200 per person. The space that took 19 years to paint and 3 years to restore was repurposed as a drinks lounge for festival-goers.
The space that took Thornhill 19 years to paint and conservators 3 years to restore was repurposed as a drinks lounge for festival-goers paying GBP 200 a head.
AnalysisWill Palin, who led that conservation project, is now a Foundation trustee who has governance responsibility for the decision to allow this use. The GBP 3.1 million of public Heritage Lottery funding was awarded to protect the Painted Hall for the nation, not to create a premium hospitality venue for a private promoter. Whether this use is consistent with the conditions attached to that funding is a question Historic England and the Heritage Lottery Fund should be asking.
The Planning Breach Nobody Enforced
Under Section 55(1) of the Town and Country Planning Act 1990, "development" means the carrying out of building, engineering, mining or other operations on land, or the making of any material change in the use of any buildings or other land.
A 10,000-capacity open-air electronic music festival with staging, PA systems, crowd barriers, generator compounds, and backstage facilities is a material change of use from the site's established heritage and educational purpose. The installation of that infrastructure constitutes building or other operations on land. Both limbs of Section 55(1) are engaged.
Section 57(1) is absolute: planning permission is required for the carrying out of any development of land. There is no exemption for charities. No exemption for heritage sites. And critically, no exemption for events with a premises licence.
The Foundation's own behaviour confirms they know the planning regime is a problem. In their parliamentary evidence, they explicitly asked the government to loosen planning rules for heritage sites (Item 4 of their policy requests). You do not petition Parliament to relax planning rules if you believe you are already compliant.
The Maritime Greenwich Management Plan confirms that permitted development rights are restricted within the World Heritage Site (Section 4.1.35, GPDO Amendment No.2, 2008). No exemption is available for temporary festival infrastructure.
What the Foundation's Own Plan Says
| Section | Finding |
|---|---|
| s.3.6.2.6 | When the Navy left, the government explicitly stated new uses must be "compatible with international architectural and historic importance" |
| s.4.1.12 | The NPPF designates World Heritage Sites as heritage assets of "the highest significance" where substantial harm "should be wholly exceptional" |
| s.4.3.2.2 | "Inappropriate development pressures remain a threat to the Outstanding Universal Value" |
| s.4.1.35 | Permitted development rights are restricted within the WHS |
| s.4.1.31 | Development over 1,000 sq.m must be notified to Historic England |
Inside the Licensing Hearing
In November 2025, the Licensing Sub-Committee of the Royal Borough of Greenwich heard the application from Labyrinth Festivals Ltd for a new premises licence at the Old Royal Naval College. The application was submitted by Jannath Rankou (The Fair) as agent, with Matthew Phipps (TLT LLP) acting as legal representative.
The licence application was for 9,999 capacity across 8 event days in 2026 and 9 from 2027 onward. Licensable activities: sale of alcohol, regulated entertainment, and late-night refreshment. Hours sought: 12:00 to 23:00, with additional late-night refreshment to 00:30.
The council's Community Safety team, led by Daniel Bygrave, submitted representations. The key condition: a 65dB LAeq 15-minute noise limit at the nearest noise-sensitive premises. This replaced the 2025 arrangement where 65dB was described as "a target" rather than a binding condition.
42 conditions were attached to the licence. They include: noise monitoring at specified measurement points, a post-event noise report, a written event management plan, crowd management requirements, CCTV, SIA-licensed security, and a dedicated complaints line.
Condition 1: Music noise level shall not exceed 65dB LAeq 15 mins at the nearest noise-sensitive premises
Condition 4: A post-event noise report shall be submitted to the council within 28 days
Condition 12: A written Event Management Plan must be agreed with the council and emergency services
Condition 18: CCTV covering all public areas, recordings retained for 31 days
Condition 31: A dedicated complaints telephone line, operational throughout the event and for 24 hours after
Condition 42: Maximum capacity 9,999 persons at any time
What the hearing did not address: whether valid planning permission exists. The licensing regime and the planning regime are separate. The Sub-Committee's jurisdiction was limited to the four licensing objectives (prevention of crime and disorder, public safety, prevention of public nuisance, protection of children from harm). Whether the events constitute lawful development was not within their remit, and nobody raised it.
2026: Bigger, Louder, Still No Answers
In November 2025, Greenwich Council's Licensing Sub-Committee granted Labyrinth a new premises licence (No. 18546) for 8 event days in 2026 and 9 from 2027 onward. Capacity: 9,999. The 65dB noise limit, previously only "a target," is now an enforceable condition. There are 42 conditions in total.
The 2026 lineup includes Moby, Peggy Gou, The Kooks, Adriatique, and Overmono. Production is by High Scream, who worked on the Paris Olympics 2024 closing ceremony. VIP ticket holders will again get access to the Painted Hall.
Whether valid planning permission exists for the 2026 events remains an open question.
The Questions That Need Answering
Has a Heritage Impact Assessment been conducted for Labyrinth, as required by the Maritime Greenwich Management Plan? If not, why not? And if Historic England was never asked to assess the events because its CEO sat on the Foundation's board, who was protecting the site?
Has Duncan Wilson formally recused himself from all board discussions and votes relating to Labyrinth?
Does valid planning permission exist for the 2026 events? If the answer is no, the same statutory breach will recur this August.
Is the relationship between the Foundation and Labyrinth Festivals Ltd documented to the standard required by Charity Commission guidance RS2?
Why did the Royal Borough of Greenwich grant an expanded premises licence for 2026 when the planning permission question from 2025 was never formally resolved?
Does the lease from Greenwich Hospital (the Crown charity freeholder) permit this scale of commercial activity?
Was the use of the Painted Hall as VIP hospitality consistent with the conditions attached to the GBP 3.1 million Heritage Lottery Fund grant that paid for its conservation?
And the question that sits above all of them: should a 300-year-old baroque masterpiece that took years of painstaking conservation work be used as a VIP lounge for festival-goers paying premium ticket prices?
1. Planning Enforcement
Any person can submit a formal planning enforcement complaint to the Royal Borough of Greenwich, requesting that the council investigate the breach of planning control under Section 172 of the TCPA 1990. If the council declines to enforce, that decision can be challenged through the Local Government and Social Care Ombudsman or by judicial review.
2. Charity Commission
Concerns about the Greenwich Foundation's governance, including the Duncan Wilson conflict of interest and the relationship with Labyrinth Festivals Ltd, can be raised directly with the Charity Commission. The Commission has the power to open a statutory inquiry under Section 46 of the Charities Act 2011.
3. Historic England
A formal request can be made to Historic England asking whether a Heritage Impact Assessment has been conducted for Labyrinth on the Thames, whether the 1,000 sq.m notification threshold was triggered, and whether the organisation considers the events compatible with the Outstanding Universal Value of the Maritime Greenwich World Heritage Site.
4. Heritage Lottery Fund
The National Lottery Heritage Fund, which contributed GBP 3.1 million to the Painted Hall conservation, can be asked whether the use of the Painted Hall as VIP festival hospitality is consistent with the grant conditions.
5. UNESCO
Concerns about threats to the Outstanding Universal Value of a World Heritage Site can be raised with the UNESCO World Heritage Centre. If the events are found to impact the OUV, the Centre can request a State of Conservation report from the UK government and, in extreme cases, place the site on the List of World Heritage in Danger.
We have seen the documents. We have traced the corporate structures. We have read the Foundation's own admissions to Parliament. We have named every person in the decision chain. The facts lead to a simple conclusion: a financially desperate charity, under pressure to generate commercial revenue, has partnered with a private promoter to stage mass-scale electronic music festivals on one of the most significant heritage sites in the world, without proper planning permission, with the head of England's heritage regulator sitting on its board, with a council that chose not to enforce, and with no public Heritage Impact Assessment on record.
The 2026 events are scheduled for August. The window for accountability is now.
