Retiring From a UK Professional Practice: Getting PI Run-Off Right

Your liability for past work does not retire when you do. Run-off cover is how a closing practice keeps yesterday’s work insured — here is how to structure it.

The problem: claims-made cover doesn’t retire when you do

Professional indemnity policies are written on a claims-made basis: the policy that responds is the one in force when the claim is made, not the one in force when the work was done. While you are trading and renewing each year, that distinction is invisible — there is always a current policy to catch whatever surfaces. The moment you retire, close the practice and stop renewing, the safety net disappears. Work you completed years ago can still generate a claim, but there is no live policy for that claim to land on. Your liability for past work survives retirement; your insurance, unless you act, does not.

Run-off cover exists to close that gap. It is a policy (or a series of renewals) maintained after the practice ceases, covering claims made after cessation that arise from work done before it.

How long to maintain run-off

There is no single universal answer, and be wary of anyone who quotes you one. The sensible duration is a judgement built from several inputs:

• Limitation periods. The law limits how long claimants have to sue, but the clock runs differently depending on whether the engagement was a simple contract or executed as a deed, and separate rules can extend time where damage is discovered late. The practical effect is that exposure horizons vary by how your engagements were papered — a question worth answering from your actual files, with advice where needed, rather than from a rule of thumb.
• Your professional body’s rules. Several regulators and professional bodies impose their own run-off expectations on ceasing firms, and some operate arrangements that provide an element of cover automatically. Check the current requirements for your profession directly — they differ, and they change.
• The nature of the work. Long-latency work — structural design, pension transfers, tax structuring, conveyancing — argues for a longer tail than short-latency, quickly-tested work.
• Contractual promises. Appointments, warranties and settlement agreements sometimes commit the firm to maintaining PI for a stated period after completion. Those promises don’t expire because you retired; inventory them before deciding anything.

What run-off tends to cost, and why the shape matters

Qualitatively, run-off pricing follows a recognisable trajectory. The first year after cessation is typically the most expensive relative to the reduced activity, because the policy still stands behind the entire accumulated back-book of work at the moment of maximum uncertainty. As the years pass without incident, the unexpired exposure shrinks — old work either generates claims or quietly ages out of relevance — and premiums generally trend downward to reflect that receding risk. Some insurers will offer a multi-year run-off block purchased at the outset rather than annual renewals; the attraction is certainty — cover that cannot lapse because a future renewal was missed, forgotten or declined — and it is worth pricing both structures before choosing. Whatever the structure, budget for run-off as a real cost of closing the practice, in the same way you budget for closing the office.

Successor practice: the question that changes everything

Before buying anything, establish whether there will be a successor practice. If your firm is acquired, merged, or its business is carried on by another firm — same clients, same work, continuity of goodwill — the successor’s PI arrangements may pick up liability for the old firm’s past work, and in some professions the rules on when a firm counts as a successor are prescriptive. Handled well, this can transfer the run-off burden to the continuing firm’s policy. Handled loosely, it produces the worst outcome available: genuine ambiguity, years later, about whose insurance answers a claim — with the claimant happily suing everyone while the insurers argue. If a sale or merger is part of your retirement, make the treatment of past liabilities an explicit, written term of the deal, and make sure both firms’ insurers know what has been agreed before completion.

Retiring from a partnership rather than closing a firm

An individual retiring from a continuing partnership or LLP is usually in a happier position: the firm’s ongoing policy typically continues to cover the firm’s past work, including yours. The points to verify are that the policy covers former partners and members for work done while they served, and what happens if the firm itself later ceases or fails. Getting written confirmation on both is a small task now and a large comfort later.

A practical sequence for the year before you stop

• Inventory live obligations: appointments, warranties and retainers with insurance-maintenance clauses.
• Check your professional body’s current cessation and run-off rules.
• Decide the structure: annual run-off renewals versus a multi-year block; confirm the limit and basis carried into run-off.
• Resolve successor-practice status in writing if anyone is taking over the business.
• Notify circumstances scrupulously before the final live policy expires — anything you already know about must be reported to the expiring policy, not left for run-off to argue over.
• Keep records: engagement letters, files and policy documents remain your evidence for as long as claims remain possible.

Where a broker fits

Run-off is a small market with meaningful differences between insurers on price, duration options and willingness to stay on risk. Apex arranges run-off for retiring professionals and small practices, and we would far rather have the structuring conversation a year before cessation than a month after. If retirement is on your horizon, bring us the contracts and we’ll help you map the tail.
