What Is the Takeover Panel? A Simple Guide to the UK's Takeover Referee

So, what is the Takeover Panel? Formally, the Panel on Takeovers and Mergers is the independent body that writes and enforces the UK's Takeover Code, the rulebook governing takeovers of UK-quoted companies. It was set up in 1968, it sits in London, and it has one core purpose: to make sure shareholders are treated fairly and that bids run to an orderly timetable.

Notice what it does not do. The Panel doesn't decide whether a deal is good for Britain. It doesn't rule on competition, jobs or national security. It doesn't tell you whether the price is any good.

Think of it as the referee. It doesn't score the goals or pick the teams. But when it blows the whistle, everybody stops.

If you work in corporate finance, M&A, capital markets or corporate law, the Panel is the regulator most likely to ring your client at 7 am. In this article, we'll explain:

• What the Takeover Panel is
• Why it exists
• How the Takeover Code works
• Key rules professionals should know
• Real-world examples of the Panel in action

So let's unpack who it is, what it can actually do to you, and why 30% is the most important number in UK public M&A.

The Takeover Panel at a Glance

Let's take a closer look at two of those rows.

The legal footing. The Panel spent nearly 40 years as a purely self-regulatory body. Then the EU Takeovers Directive arrived, and the Companies Act 2006 gave the Panel certain statutory powers. Today, it has the power to demand documents and information, to make compensation rulings, and to enforce its rulings through the courts.

The funding. You have probably paid the Panel yourself without noticing. Buy or sell more than £10,000 of UK shares and a small charge appears on your contract note: the PTM levy. It rose from £1 to £1.50 per trade on 2 December 2024 — the first increase in 22 years. This funds the regulator that oversees billions in deal value. Value for money, arguably.

Who's Actually in the Room?

"The Panel" is a convenient shorthand for four moving parts.

1. The Executive. The day-to-day regulator, and the one you'll speak to. Advisers consult it frequently, often in real time, before making announcements or buying shares. It grants waivers, gives rulings and interprets the Code as a deal unfolds.
2. The Hearings Committee. Where contested rulings and disciplinary cases go. This is a body that imposes serious sanctions.
3. The Code Committee. The rule-writers. It consults publicly (Public Consultation Papers) and publishes the outcome (Response Statements) before changing the Code.
4. The Takeover Appeal Board. An independent body that hears appeals against Hearings Committee decisions.

What does the Takeover Panel Enforce?

The Code contains 38 Rules. In practice, a handful will drive nearly every conversation on a live bid.

The Panel is also busier than most people assume.

In the year to 31 March 2025, an offer period commenced for 87 companies, 57 firm offers were announced (49 of them structured as schemes of arrangement), and the Executive granted 51 Rule 9 waivers. Around a third of those offers came from private equity and similar investors.

2 Examples You Need to Know

Now let's watch two of those rules do real damage.

BHP, Anglo American, and a 28-day Clock (2024)

In 2024, BHP made an approach for Anglo American valued ultimately at roughly £38.6 billion. This was one of the largest mining deals ever contemplated. It didn’t happen because BHP did not offer a price or structure for the bid that the board of Anglo was prepared to recommend within the time constraints of Rule 2.6.

Once BHP was named, the PUSU clock started. Anglo rejected three proposals, then agreed to a seven-day extension (which only a target can request, and only the Panel can grant), pushing the deadline to 5.00 pm on 29 May 2024.

Anglo refused to extend again. BHP now had two choices, and only two: announce a unilateral (hostile) firm offer under Rule 2.7, or announce it wasn't bidding. Minutes before the deadline, BHP confirmed it would not make a firm offer.

The consequence was automatic. Under Rule 2.8, BHP was restricted for six months from coming back.

That is the Takeover Panel's timetable in action, and it is precisely why the PUSU deadline is such a powerful defensive tool.

Kraft, Cadbury: The Promise That Wasn't (2010)

The BHP episode shows the Code working smoothly. This one shows why the Code exists at all.

During its £11.7 billion hostile pursuit of Cadbury, Kraft said publicly that it believed it could keep Cadbury's Somerdale factory near Bristol open. Cadbury had planned to close it and shift production to Poland. Kraft's statement was widely read as a lifeline for around 400 jobs.

Seven days after Kraft completed the takeover, it announced Somerdale would close after all.

The Panel investigated and publicly criticised Kraft for failing to meet the standards required by Rule 19.1. The Panel accepted that Kraft genuinely believed what it said. That wasn't the point. Kraft had made a statement about people's livelihoods without knowing how far advanced Cadbury's closure plans already were, including the substantial investment Cadbury had already sunk into its Polish facilities.

The fallout reshaped UK takeover regulation.

The 2011 Code reforms that followed introduced the automatic 28-day PUSU regime and the naming of potential bidders in the possible offer announcement, banned inducement fees and most deal protection measures, and forced bidders to disclose far more about how they were financing a bid. The Panel has also tightened up its rules on statements of intention.

In short, the lesson for practitioners: in a Code transaction, a statement of intent is not PR. The Panel will hold you to what you say.

What Happens if You Break the Rules?

Here's the surprise. The Panel doesn't hand out FCA-style fines. Its escalation ladder looks like this:

• Private censure — a quiet word that follows you around the City
• Public censure — a published statement naming you
• Compensation rulings — the Panel can require you to pay shareholders what they lost
• Court enforcement — the Panel can and does go to court to compel compliance
• Cold-shouldering — the nuclear option

Cold-shouldering means no FCA-regulated firm may act for you on any Code transaction for a period of time.

No bank. No broker. No adviser.

In a market that runs on advisers, you are effectively frozen out.

It has been used sparingly. In October 2019, the Panel cold-shouldered David King, then chairman of Rangers International Football Club, for four years. King had acted in concert with three other investors to take his interest above 30% and had failed to make the mandatory Rule 9 offer that should have followed. He also misled the Panel Executive during its investigation. Before that, the Panel had already taken the extraordinary step of going to court to force him to make the offer — and won, with the court rejecting his argument that he couldn't afford it.

At the time, it was only the fourth cold-shouldering in the Panel's history. Rare, then. But that's the point: the Panel rarely needs to escalate, because the City knows exactly what waits at the top of the ladder.

Recent Changes

The Code is a living rulebook. Three recent changes matter:

Narrower jurisdiction (3 February 2025). The Code now applies only to companies registered in the UK, Channel Islands or Isle of Man whose securities are — or were within the past two years — admitted to trading there. The old "residency test" for unquoted companies is gone. Companies caught by the old rules but not the new ones have a transition period running to 2 February 2027.

A higher PTM levy (December 2024). Up to £1.50 per trade over £10,000, after the Panel reported operating at a deficit.

Dual class shares, IPOs and buybacks (4 February 2026). New rules govern how the Code applies to dual class share structures, what companies must disclose about the Code at IPO, and when a share buyback can trigger a Rule 9 mandatory offer.

The latter matters more than it sounds after the recent change in London listing rules to allow dual class shares with multiple voting rights. These could have pushed a passive shareholder over 30% without them lifting a finger — and straight into a mandatory bid obligation they never wanted.

Developing Your Knowledge of the Takeover Code

Takeover Code knowledge is one of those skills that stays invisible right up until the moment it isn't. Sit in a deal meeting, and you'll hear it everywhere: concert party, Rule 9 waiver, PUSU deadline, Day 60, cash confirmation.

Professionals who understand what those terms actually trigger are trusted with live mandates.

The people who don't? They nod. Then they Google it afterwards.

Ready to stop nodding?

You don't need to become a takeover lawyer. You need to know which rule is about to bite, why the 30% line exists, what a Rule 2.7 announcement commits your client to, and when to pick up the phone to the Panel Executive before the mistake happens rather than after.

Redcliffe Training's Introduction to the Takeover Code course gives you exactly that: a practical, transaction-level grounding in how the Panel works, how the Code applies, and how deals are really run under it. Taught by a practitioner who has sat on both sides of the table.

FAQ

Is the Takeover Panel a government body?

No. It's independent, funded by the market it regulates. But it operates under statutory powers granted by the Companies Act 2006, and its decisions can be enforced by the courts.

Does the Code apply to private companies?

Generally not any more. Since February 2025, the focus is firmly on UK-registered, UK-quoted companies — including AIM companies — plus those quoted within the last two years.

Can you appeal a Panel ruling?

Yes. Executive rulings can go to the Hearings Committee, and from there to the independent Takeover Appeal Board. What you cannot do is ignore a ruling and hope it goes away. Ask David King.
