Andrew Mountbatten-Windsor received private income from subletting three cottages on his Windsor Royal Lodge estate while paying a “peppercorn rent” to the crown estate, a report into royal property arrangements has revealed.
The National Audit Office (NAO) review also shows that King Charles pays an “adjusted” rent from his private Duchy of Lancaster income, below open market value, for his disgraced brother’s non-working royal daughters, princesses Beatrice and Eugenie, to live in royal palaces.
Meanwhile, the Prince and Princess of Wales’s Forest Lodge home in Windsor underwent £400,000 repairs carried out by the crown estate before the couple moved in with their three young children last year.
William and Catherine took out a 20-year lease in July on the Grade II-listed Georgian house, with gardens, paddock, a barn and three cottages set within 7.4 hectares, and pay £307,200 rent a year, reviewed every five years, the NAO said. They paid no upfront premium, and are responsible for internal refurbishments and alterations.
Details of the properties are revealed in the report, published on Friday, which will form the basis of the Commons public accounts committee’s inquiry into royal properties after the public outcry when it emerged in October Mountbatten-Windsor was paying a peppercorn rent on Royal Lodge, the Windsor mansion from which he was eventually evicted by Charles.
The NAO found rent and lease arrangements for the royals differed depending on why the accommodation was required and whether the property was managed by the crown estate – a self-funding public corporation managing assets on behalf of the crown – or the royal household.
For those managed by the royal household, “adjusted rent” was typically 60% of the open market valuation because the properties are within a secure cordoned area requiring tenants to have security vetting.
The rent for Beatrice’s St James’s Palace apartment is 68% of market value, while Eugenie’s Kensington Palace cottage is 64%. Eugenie’s rent was 50% of the 2018 open market value from 2020 to 2021, and ranged from 55% in 2022 to 63% in 2025, while Beatrice’s was 60% of the 2020 market value from 2020-2021 and ranged from 62% to 68% between 2022 and 2025, the NAO said.
Charles also pays rent for Prince and Princess Michael of Kent’s Kensington Palace apartment, although there was no record of valuation of that lease prior to 2026
Mountbatten-Windsor, now evicted to Marsh Farm on the Sandringham Estate, Norfolk, had a lease that permitted subletting, though it was not known how much he received through this.
He paid a £1m premium and £7.5m on refurbishment of Royal Lodge under the 75-year lease in 2003, and could be entitled to between £301,967.66 and £488,342.21 compensation by surrendering it early, the report said. However, the crown estate has previously said it is likely he will not be owed any compensation once dilapidations are taken into account.
Sources suggested Mountbatten-Windsor’s subletting did not generate a profit and that the rent was set at a rate to cover only maintenance and running costs for staff living there. However, no figures, such as repair and household costs versus rental income, or copies of the rental agreements, have been made public.
Public money through the sovereign grant is used for the maintenance and operational costs of the occupied royal palaces. But sources suggested the adjusted rents paid by the king for Beatrice and Eugenie’s palace residences covered the costs met by the sovereign grant on those properties and therefore there was no additional cost to the grant.
Norman Baker, a former Liberal Democrat minister, said the arrangements for Mountbatten-Windsor added “insult to injury … not only that Andrew was able to have a peppercorn rent for a gigantic property, but then to make potentially millions on the side from subletting properties. The money should have gone to the crown estate, not into [his] pockets”.
The Duke and Duchess of Edinburgh paid a £5m premium for Bagshot Park, their home on the Windsor estate. A new lease granted in August 2007 replaced the previous lease, with Prince Edward paying £1.38m against the original 1998 lease. The couple pay a peppercorn rent. They also generated income by renting out the stable block up to 2020, the report said.
Seven members of the royal family lease five properties from the crown estate. The lease terms vary, and were agreed at the open market value at the time, with the crown estate seeking independent professional advice on the financial terms, the report said.
The royal household provides 11 working royals, including Charles and Camilla, with seven residences within the occupied royal palaces at no cost in exchange for their official duties.
The report states: “Generally, we found [the crown estate] applied standard practices across the leases we examined and in line with its processes. Where we found differences, these related to specific terms within lease agreements for the same lease type. Each lease was agreed at different points in time over a 50-year period, so some variation in practice and outcomes is to be expected.”
A spokesperson for the crown estate said:* *“The crown estate welcomes the National Audit Office’s review, which confirms its leases with members of the royal family were agreed in line with independent, professional advice and open market valuations. We look forward to discussing the report further with the public accounts committee in due course.”
A Buckingham Palace spokesperson said: “We are grateful to the National Audit Office for this report, which is in line with the royal household’s commitment to transparency. We hope that the findings will help correct, clarify or contextualise a number of points regarding royal properties. As the report notes, arrangements for properties managed by the royal household vary based on a number of factors to ensure residences are filled appropriately, depending on their location, tenants and purpose.”
Four leading AI models discuss this article
"The real takeaway is governance transparency and reform need, not evidence of financial misappropriation."
NAO's report frames royal leases as largely compliant with independent valuations, with some rents below market due to security constraints and time-based valuations. The strongest read is not that Andrew or Beatrice are siphoning funds, but that a 50-year constellation of legacy terms invites questions about transparency and reform, especially since public money funds maintenance via the sovereign grant. The risk to markets is political more than financial: public backlash could pressure reform of Crown Estate governance, lease cadence, and rent-setting. Yet the NAO notes standard practices and independent advice, and the Beatrice/Eugenie arrangements appear to cover grant costs; the real risk lies in perception and process modernization, not criminality.
Even if technically compliant, the optics of private subletting near a colossal asset and peppercorn rent undermine public trust and invite future reforms regardless of profitability.
"The reliance on 'adjusted' rental valuations creates an institutional governance risk that threatens the transparency and public funding model of the Sovereign Grant."
The NAO report highlights a systemic lack of standardization in royal property management, revealing a portfolio where 'market value' is often a malleable concept. While the focus is on Andrew’s subletting, the real financial risk is the 'adjusted rent' mechanism used for non-working royals. By discounting market rates by 30-40% under the guise of security requirements, the Crown Estate is effectively subsidizing private living via public-adjacent assets. This creates a governance risk: if the Crown Estate's valuation methodology is perceived as opaque or politically influenced, it undermines the institutional credibility of the Sovereign Grant. Investors should monitor the Public Accounts Committee inquiry, as any move toward mandatory full-market valuation could force a significant, and potentially negative, restructuring of royal household balance sheets.
One could argue these 'adjustments' are simply the cost of maintaining high-security, historic assets that would otherwise be liabilities or prohibitively expensive to secure for private tenants.
"The NAO found the crown estate applied standard professional practices; the scandal is reputational theater around Andrew, not systemic financial mismanagement of royal properties."
This is a governance and reputational story, not a financial market mover. The NAO report actually vindicates the crown estate's process—independent valuations, standard practices applied consistently. Andrew's subletting generated no profit per sources; the 'peppercorn rent' reflects security costs baked into adjusted valuations (60% of market). The real issue is political optics: a disgraced royal subletting while underpaying looks bad, but financially it's noise. The crown estate is self-funding; sovereign grant impacts are marginal. William/Catherine's £307k annual rent on Forest Lodge is market-rate for that asset class. The story conflates 'unfair-seeming' with 'financially material' and misses that adjusted rents for Beatrice/Eugenie apparently offset sovereign grant costs.
If subletting agreements were genuinely profit-neutral, why weren't rental income figures and maintenance costs disclosed? The opacity itself suggests either political sensitivity or that 'sources' are unreliable proxies for actual economics.
"Crown Estate's below-market royal leases create a small but recurring revenue shortfall that Treasury ultimately absorbs without direct market pricing signals."
The NAO report highlights structural subsidies in Crown Estate leases, with adjusted rents at 60-68% of market value for royal tenants and peppercorn arrangements allowing subletting income retention. This diverts potential revenue from a self-funding public body whose surpluses support the UK Treasury, creating a hidden fiscal drag estimated in the low millions annually. Subletting clauses and early surrender compensation risks add opacity, while £400k pre-lease repairs on Forest Lodge show capital allocation favoring family over commercial returns. Public accountability pressure may force revaluations post-2025, but current terms lock in below-market yields for decades.
The report explicitly states all leases followed independent valuations and standard practices at the time of signing, with variations expected over 50 years; no evidence of improper profit or additional sovereign grant cost exists.
"Long-term political reforms could force full-market valuations and shift Crown Estate finances, making the current below-market rent structure a hidden market risk rather than merely a reputational issue."
Response to Grok: Even with compliant valuations, the long-term structural subsidies baked into 60%+ of market rents create an underappreciated political risk. The issue isn't current accounting; it's governance credibility and reform trajectory. If Parliament or the PAC moves toward full-market valuations or tighter rent controls, Crown Estate balance sheets—and the sovereign grant's cost—could shift sharply. That potential re-rating is the real market signal, not today's noise.
"Forcing market-rate valuations on high-security heritage assets ignores the underlying operational costs that would likely render these properties commercially unviable for private developers."
Grok and Gemini focus on the 'hidden fiscal drag,' but they ignore the opportunity cost of these assets as non-liquid, high-maintenance heritage sites. If these properties were marketed commercially, the security and preservation mandates would likely collapse the net yield anyway. The real risk isn't the 'subsidy'—it's the potential for a populist mandate to force the Crown Estate to divest, which would trigger a fire-sale of historic assets during a period of high interest rates.
"Divestment risk is real, but only if political will shifts; the subsidy's legitimacy, not its size, is the trigger."
Gemini's divestment risk is underexplored. If populist pressure forces Crown Estate to monetize heritage assets in a high-rate environment, forced sales could crater valuations—worse than any rent adjustment. But Gemini conflates 'commercial yield collapse' with 'subsidy irrelevance.' The subsidy exists regardless of yield; the question is whether Parliament accepts it. That political threshold, not asset quality, determines whether divestment becomes policy.
"Incremental rent reviews pose a more likely path to eroding Crown Estate yields than outright divestment."
Claude underplays how incremental PAC-driven rent reviews could compound the fiscal drag I flagged earlier. Even absent divestment, forcing valuations closer to market over time would directly hit Crown Estate surpluses remitted to Treasury, amplifying sovereign grant pressures beyond one-time political shocks. This gradual re-rating path deserves more weight than all-or-nothing divestment scenarios.
The discussion panel generally agrees that the NAO report highlights governance and transparency issues in royal property management, with some rents below market value due to security constraints and legacy terms. The primary risk is political backlash leading to reform pressures, rather than immediate financial implications. The potential for full-market valuations or tighter rent controls in the future is a key concern.
