Defamation Insurance in the UK: ATE, BTE & Professional Indemnity

Defamation litigation in the UK can be extremely expensive. Insurance products — including After the Event (ATE) insurance, Before the Event (BTE) policies, and professional indemnity cover — can play a critical role in making claims viable and protecting against adverse costs.

Why Insurance Matters in Defamation Cases

The costs of defamation proceedings can escalate rapidly. Even straightforward claims can cost tens of thousands of pounds, while complex cases involving trial can reach six figures. The "loser pays" costs rule in England and Wales means that an unsuccessful party typically faces not only their own legal costs but also the other side's — potentially doubling the financial exposure.

Insurance addresses this risk in two ways: it funds your own legal costs, and it protects you against having to pay the other side's costs if you lose. Without insurance, many meritorious defamation claims would never be brought because of the financial risk involved.

After the Event (ATE) Insurance

ATE insurance is taken out after a dispute has arisen — typically after receiving legal advice that a claim is viable. It is the most common form of litigation insurance in defamation cases.

What ATE Insurance Covers

• Adverse costs: If you lose the case, the ATE policy pays the other side's legal costs (which you would otherwise have to pay personally)
• Own disbursements: Some policies also cover your own out-of-pocket expenses, such as court fees, expert witness fees, and counsel's fees
• Own solicitor costs: More comprehensive (and expensive) policies may cover your own solicitor's fees as well

How ATE Premiums Work

ATE premiums are typically deferred — meaning you do not pay until the case concludes. If you win, the premium is usually paid from your damages or recovered from the other side. If you lose, you do not pay the premium (it is covered by the policy itself). This "no win, no pay" structure makes ATE insurance accessible even to claimants with limited resources.

Premiums vary significantly based on the merits of the case, the amount at stake, and the stage at which insurance is obtained. A strong case with clear evidence will attract a lower premium than a borderline claim. Premiums typically range from 30% to 90% of the insured amount, though they can be higher for complex or risky cases.

Obtaining ATE Insurance

Specialist defamation solicitors typically arrange ATE insurance through brokers who work with underwriters experienced in media and defamation litigation. The insurer will assess the merits of the case before offering cover — effectively providing an independent evaluation of the claim's prospects.

Before the Event (BTE) Insurance

BTE insurance is taken out before any dispute arises, as part of a broader insurance policy. Many people have BTE legal expenses insurance without realising it.

Where to Check for BTE Cover

• Home insurance: Many home insurance policies include legal expenses cover that may extend to defamation claims
• Motor insurance: Some comprehensive motor policies include legal expenses cover
• Business insurance: Commercial policies often include professional indemnity or legal expenses extensions
• Trade union membership: Many unions offer legal support and funding for members' claims
• Professional body membership: Some professional associations provide legal expenses cover

BTE policies typically have lower limits than ATE policies (often £50,000 to £100,000) and may exclude defamation or limit cover to certain types of claim. Always check the policy wording carefully. If you do have BTE cover, it should generally be explored before arranging ATE insurance, as it may be more cost-effective.

Professional Indemnity Insurance

If you are defending a defamation claim rather than bringing one, professional indemnity (PI) insurance may provide cover. PI insurance is mandatory for many professionals — including solicitors, accountants, and financial advisers — and typically covers claims arising from professional services, which may include allegations of defamatory statements made in a professional capacity.

Media organisations, journalists, and publishers often carry specific media liability insurance that covers defamation claims. If you publish content as part of your business, media liability insurance is strongly advisable.

Conditional Fee Agreements (CFAs)

While not insurance, CFAs (commonly known as "no win, no fee" agreements) are often used alongside ATE insurance. Under a CFA, the solicitor agrees not to charge their fees if the case is lost. If the case succeeds, the solicitor charges their normal fees plus a "success fee" (capped at 100% of the base fees, and borne by the client from their damages).

The combination of a CFA and ATE insurance is the standard funding model for defamation claimants who cannot afford to fund litigation privately. For more on defamation legal costs, see our detailed guide.

Damages-Based Agreements (DBAs)

DBAs are an alternative to CFAs. Under a DBA, the solicitor receives a percentage of the damages recovered (capped at 50% of damages in most cases). If no damages are recovered, the solicitor receives nothing. DBAs are less common in defamation cases than CFAs, partly because defamation damages can be unpredictable.

Practical Steps

1. Check existing insurance: Review all your insurance policies for legal expenses or defamation cover before assuming you have none
2. Consult a specialist solicitor: Experienced defamation solicitors can assess your case and advise on the best funding options
3. Consider timing: ATE insurance is generally easier to obtain (and cheaper) at the pre-action stage, before significant costs have been incurred
4. Understand the costs: Ensure you understand what the insurance does and does not cover, and what your maximum exposure would be
5. Keep records: Insurers may require documentation of the claim's merits and regular updates on progress
