What is public companies insurance? 

Public companies insurance is a group of policies that protect businesses listed on a stock exchange (public limited companies or PLCs) from major hazards. It can cover events like: 

  • shareholder lawsuits after financial losses 
  • FCA or FRC investigations over company reporting 
  • discrimination or harassment claims by employees 
  • legal costs from IPO or bond offering errors 
  • cyberattacks that expose customer or financial data 

Public companies are listed on the London Stock Exchange (LSE) and sell shares to the public. They follow strict rules and face more legal and public pressure than private firms.  

They make up over 80% of the UK market. Without insurance, one legal claim could cause major financial loss. 

Why public companies insurance in the UK is critical 

A UK-listed tech company had to correct its financial results. Soon after, investors filed a large lawsuit. The business had no public offering of securities insurance (POSI), and it struggled with major legal costs. 

If it had the right insurance in place, it could have claimed for these costs. This case shows how public companies insurance can shield UK firms from the risks that come with being on the stock market. 

Public companies insurance: industry trends and emerging risks 

Public companies are taking part in more mergers and acquisitions, both in the UK and abroad. This has increased demand for warranty and indemnity insurance, along with stronger directors and officers (D&O) cover.  

At the same time, shareholder activism is rising, especially over ESG and pay. AI use is also creating new dangers linked to data and fairness. Other issues brokers need to be aware of include: 

  • group claims over ESG failures: lawsuits funded by third parties are raising D&O costs 
  • false sustainability claims investigated: FCA and ASA probes are triggering insurance policy extensions 
  • diversity rule breaches: boards risk fines if FCA targets are not met 

Brokers should watch for investor claims over high bonuses at loss-making firms which can test how far D&O policies will respond. Overseas links also raise the risk of breaching UK, US, or EU sanctions. 

Public companies insurance FAQs 

Is insurance for public companies worth it? 

Yes, it is often seen as essential and not optional. It helps safeguard the company and its directors from costly legal claims. 

Lawsuits from investors, staff, or regulators can happen at any time. One claim could cost millions and hurt a company’s name and finances. 

Common coverage options for public companies insurance are: 

  • D&O 
  • POSI 
  • employment practices liability (EPL) 
  • company legal liability (CLL) 
  • cyber insurance 
  • fiduciary liability 

Most public companies have a mix of these covers. Brokers can help build the right policy for each firm. 

Who needs public companies insurance coverage? 

This cover is useful for large firms, but also for smaller ones planning to list or expand abroad. Those who need this include: 

  • FTSE-listed companies 
  • firms planning an IPO 
  • companies with outside investors 
  • firms with international links 
  • businesses under public or media scrutiny 

Public companies insurance is made for listed businesses that encounter more legal and reporting risks. It helps secure both the company and the people running it. 

How do I claim on a company's public liability insurance? 

If someone is hurt or property is damaged by a business, they can make a claim. The steps below outline what one needs to do to make a claim: 

  1. contact the company: speak to the business and report what happened 
  2. ask for insurance details: request the name and contact of their insurer 
  3. gather evidence: collect photos, receipts, witness details, or medical notes 
  4. submit claim: send evidence to the insurer for review 
  5. wait for a response: the insurer will assess the claim and make a decision 

Keep records of all contact. If the business doesn’t respond, a solicitor or claims adviser may help.
