Professional Indemnity Insurance for Barristers

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05

Do barristers have to hold PI insurance?

Yes. Under the Bar Standards Board (BSB) Handbook, holding adequate professional indemnity insurance is a condition of practising. The core duty requires that you have insurance in place that covers all the legal services you supply, at a level that is adequate having regard to the nature of your practice and the risks it carries.

How you satisfy that duty depends on how you practise. The two routes look very different, so it is worth being clear which one applies to you before thinking about limits or price.

Self-employed barristers: the Bar Mutual (BMIF)

If you are a self-employed barrister in independent practice, the BSB Handbook requires you to be insured through the Bar Mutual Indemnity Fund Limited (BMIF), commonly called Bar Mutual. BMIF is a mutual established specifically for the Bar and is the designated body for compulsory PI cover for self-employed practitioners in England and Wales.

This is a fixed feature of practising at the self-employed Bar. You cannot substitute a policy from an ordinary commercial insurer for your primary compulsory layer — membership of Bar Mutual is the mechanism the regulator recognises. Cover is arranged directly with BMIF, and contributions are assessed by reference to your practice profile and areas of work.

Because that primary layer is mandatory and standardised, the questions Apex is asked by barristers are usually about what sits around it: whether the standard limit is enough, and whether every strand of what you do is actually captured.

Employed and dual-capacity barristers

If you practise as an employed barrister — in-house at a company, in local government, at the CPS or within a firm — your PI position is normally covered by your employer’s arrangements for the work you do in that role. The compulsory BMIF route is aimed at self-employed independent practice, so employed practitioners should confirm exactly what their employer’s policy covers and, crucially, what it excludes.

Complications arise when a barrister wears more than one hat: employed for a day job but also accepting self-employed instructions, or moving between chambers work and consultancy. In those situations there can be gaps between one arrangement and another. This is a common reason barristers ask us to review the overall picture rather than a single policy.

The specific risks a barrister carries

Professional indemnity insurance responds to claims that you were negligent, or breached a professional duty, in the legal services you provided. For the Bar, the exposures are distinct from those of solicitors or other advisers:

• Negligent advice or advocacy — the abolition of advocates’ immunity means a barrister can, in principle, be sued for the conduct of a case as well as for written advice.
• Missed limitation dates and procedural deadlines — particularly where a barrister is closely involved in the running of litigation.
• Drafting errors — a mistake in pleadings, a contract, a trust instrument or other document that causes a client loss.
• Advice that fails to consider a relevant point of law — leading to a decision the client would not otherwise have taken.
• Public access work — taking instructions directly from lay clients, without a solicitor as intermediary, changes the risk and the client-handling obligations.
• Non-reserved and adjacent activities — arbitration, mediation, expert determination, training, or sitting in a quasi-judicial capacity may or may not fall within a standard arrangement.

The value of a barrister’s advice can be far larger than the fee earned for giving it. A single opinion on a high-value commercial dispute, a tax structure or a construction claim can expose you to a loss that dwarfs your annual income — which is precisely why the adequacy of your limit matters.

What limit of indemnity is ‘adequate’?

The BSB does not fix a single monetary figure for every barrister. The duty is to hold cover that is adequate for your practice. What is adequate for a junior doing publicly funded family work is not adequate for a silk advising on nine-figure commercial disputes.

Bar Mutual provides a standard limit of indemnity as part of membership. For many practitioners that base limit is appropriate. For others — particularly those in commercial, chancery, tax, construction or professional negligence fields — the compulsory layer may not reflect the true financial size of the matters they touch. The sensible test is to look at the largest realistic loss a single piece of your work could cause, not the average.

Illustrative limits such as £1m, £2m or £5m are common reference points, but the right figure is the one that fits your exposure — not a number chosen for tidiness.

Where Apex fits alongside Bar Mutual

Apex is an FCA-authorised broker, not a substitute for BMIF. For self-employed barristers, the compulsory primary layer stays with Bar Mutual. Where we add value is around and beyond it:

• Top-up / excess layer cover — additional indemnity that sits on top of your BMIF limit for higher-value work.
• BSB-authorised entities — barrister-owned entities and ProcureCos have their own insurance needs, including the business itself, not just individual practitioners.
• Chambers-level and management exposures — office, cyber, directors’ and officers’, employment practices and other risks that are not part of a personal PI arrangement.
• Adjacent and non-mainstream activities — arbitration, mediation, expert work, lecturing and consultancy, where you need certainty that the activity is insured.
• Employed and dual-capacity barristers — reviewing whether the work you do outside an employer’s cover leaves a gap.

Our job is to read the whole picture, identify where the compulsory arrangement stops, and place cover that closes the gap on terms that make sense for your practice. We start with a short proposal so we understand your practice areas before recommending anything.

How a claim actually works

Most PI cover is written on a “claims-made” basis, meaning the policy that responds is the one in force when the claim is made or a circumstance is notified — not the one in force when you did the work. Two practical points follow. First, notify circumstances promptly: if you become aware of something that might give rise to a claim, tell your insurer, even before a formal claim lands. Late notification is one of the most common ways cover is prejudiced. Second, if you leave practice, think about run-off — cover for claims that surface after you stop working. Bar Mutual’s arrangements address the position for its members; if you carry additional or entity cover, run-off needs to be considered separately.

Common questions

Can I use an ordinary commercial insurer instead of Bar Mutual?
For your compulsory primary cover as a self-employed barrister in independent practice, no — the BSB Handbook requires membership of the Bar Mutual Indemnity Fund. A commercial broker like Apex can arrange top-up, entity and adjacent cover on top of BMIF, but not replace it.

Does the standard Bar Mutual limit cover high-value commercial work?
It may not. The base limit suits many practitioners, but if a single opinion or piece of advocacy could expose you to a loss well above that figure, a top-up layer is worth reviewing. The test is your largest realistic exposure, not your fee income.

I’m an employed barrister who also takes some private instructions — am I covered?
Not necessarily by one arrangement. Your employer’s cover typically applies to your employed role only. Self-employed instructions may need their own cover. It is worth having the whole position reviewed so there is no gap between the two.
