London’s skyline is full of glass and ego, but few icons carry the weight of Battersea Power Station. It’s the ultimate trophy asset—a £9 billion regeneration project that turned a derelict shell into a playground for Apple and high-end shoppers. But behind the Art Deco chimneys, a massive legal and financial storm is brewing. The news that the owners have held talks to sell off chunks of undeveloped land isn’t just a routine real estate move. It’s a tactical play in a high-stakes war over how much this project is actually worth.
The core of the issue isn't just about selling dirt and concrete. It’s about a direct challenge to the integrity of the project's books. Don O’Sullivan, the former CEO who once guided King Charles around the site, is now the project's biggest headache. He’s filed an explosive whistleblowing claim at the London South Employment Tribunal, alleging he was sacked for calling out "serious financial misreporting."
The valuation gap that sparked a firestorm
Real estate at this level is often a game of smoke and mirrors. O’Sullivan’s case hits where it hurts: the balance sheet. He contends that undeveloped land was being recorded at values far higher than what independent assessments suggested. When you’re dealing with a 42-acre site, even a small percentage "tweak" in valuation translates to hundreds of millions of pounds.
Why does this matter? Because the project is owned by a consortium of Malaysian heavyweights: Sime Darby, SP Setia, and the Employees Provident Fund (EPF), which is Malaysia's national pension fund. If the assets are being "flattered" to look better than they are, it’s not just a boardroom spat. It’s a potential scandal involving the retirement savings of millions of people thousands of miles away.
The owners, of course, aren't taking this lying down. They’ve "strongly denied" the claims, pointing to audits by PwC and independent forensic reports that say everything is above board. They argue O’Sullivan’s concerns weren't borne out. But the timing of these land sale talks tells a different story. If you’re confident in your valuations, why rush to talk to buyers while a tribunal case is looming?
Selling off the remaining 16 acres
We’re currently at a crossroads for the site’s final phases. About 16 acres of the original 42-acre masterplan remain undeveloped. Recently, the developer appointed Studio Egret West to "reset" the masterplan for these remaining plots. They’re looking to deliver up to 3.2 million square feet of new space—homes, offices, and culture.
But here’s the reality: building in London in 2026 is brutally expensive. Construction costs have spiraled by 40% over the last few years. Many developers are finding that projects approved a decade ago simply don't make sense anymore. By entering talks to sell these undeveloped plots now, the Malaysian owners might be looking for an "out." They can offload the risk of further development and use the cash to shore up a balance sheet that’s under intense legal scrutiny.
Selling land at the "centre of a dispute" is a bold move. It forces a market test. If a buyer pays the price the owners claim it’s worth, O’Sullivan’s case loses its sting. If the bids come in low, it confirms the whistleblower’s fears.
A project of two halves
Walking through the Turbine Halls today, you’d never guess there was trouble. The place is packed. It’s a genuine success story of urban placemaking. Yet, the corporate structure behind it looks increasingly fragile.
- The Completed Assets: The Power Station building itself, the Apple headquarters, and the shopping mall are the "crown jewels." There are even rumors of a £2 billion sale for these specific assets, possibly to Chinese investors.
- The Future Phases: This is where the risk lives. Plot 4, which is at the heart of the current dispute, represents the "next chapter" that might now be written by someone else entirely.
Wandsworth Council is also in the mix. They’ve finally squeezed an agreement out of the developers to build over 200 council homes on the site by 2029. Any change in land ownership needs to respect these social obligations, adding another layer of complexity to any potential sale.
What happens next for Battersea
Don't expect a quick resolution. The Employment Tribunal has listed the final hearing for 2029. That is an eternity in the world of property development. Between now and then, we’re going to see a lot of posturing.
The owners are trying to move forward as if it’s business as usual. They’re starting construction on new Gehry-designed buildings and talking up the "next chapter." But the shadow of the O’Sullivan case isn't going away. Every time they try to sell a plot or bring in a new partner, the "integrity of financial reporting" question will be at the top of the due diligence checklist.
If you're an investor or just a Londoner watching the site evolve, keep your eye on the sales. If these undeveloped plots sell quickly and for high prices, the current management wins. If they sit empty or the talks collapse, it’s a sign that the market doesn't believe the numbers on the page.
If you want to track the actual progress of these sales, monitor the Land Registry filings for the Nine Elms area over the next six months. That’s where the truth will eventually show up, far away from the PR statements and tribunal filings.
