Run-Off Cover Explained

Updated April 2026

What exactly is run-off cover in PI insurance?

Run-off cover (also called 'tail cover') is professional indemnity insurance that continues after you stop practicing. When you retire, close your business, or exit a profession, your standard PI policy ends. But clients can still sue you for work you did years earlier. Run-off cover protects you against these historic claims. Example: you retire as an architect in 2025. In 2029, a client discovers your 2018 design was defective and sues for GBP500,000. Without run-off cover, you're paying personally. With it, your insurer covers the claim. Run-off cover is essentially extended liability protection for your professional history.

When do you actually need run-off cover?

When you stop practicing professionally. If you retire, cease self-employment, close your business, or leave your profession, you need run-off cover. Even if you're certain no claims will come, a single claim could be catastrophic. Most professional bodies require it. Solicitors, accountants, architects, and regulated professionals are often required to maintain run-off cover for 6-12 years after ceasing practice. Unregulated professionals should maintain it for at least 6 years (the typical limitation period for claims). Some industries have longer periods--construction professionals might need 12-15 years because claims can emerge long after defects appear.

How much does run-off cover cost and how long do you need it?

Run-off cover typically costs 50-300% of your standard annual premium, depending on your profession and chosen tail period. A solicitor paying GBP2,000/year might pay GBP1,000-GBP6,000 for a 7-year run-off tail. The cost depends on: your chosen tail period (6, 7, 10+ years), your claims history, your profession's claim frequency, and any previous claims. Most professionals choose 6-7 year tail periods because UK's 6-year limitation period means most claims would have been brought. High-risk professions like construction choose longer (12+ years). You pay the run-off premium once (sometimes split over first few years), then you're protected for the tail period. This is often called 'claims made' extended--you're covered for old work if the claim is made during the tail period.

"Run-off cover is the insurance you hope never to use. But when you're retired and a claim from 2015 work emerges, you're absolutely glad you bought it. It's often a legal requirement anyway, but even where it's not mandatory, it's essential."

Frequently Asked Questions

Is run-off cover mandatory for all professionals?▼

For regulated professions (solicitors, architects, accountants), usually yes. For unregulated professionals, it's recommended but not legally required.

Can you get run-off cover after you've already retired?▼

Yes, but it's more expensive and underwriters scrutinize your claims history more carefully. Buy it before you stop practicing.

How long after retiring should you maintain run-off cover?▼

At least 6 years (standard limitation period). Some professions require 7-12 years. Check your profession's requirements.

What if you die before the run-off period ends?▼

Your estate is still covered. Beneficiaries or representatives can claim under the run-off policy if claims arise.

Does run-off cover apply to work done before you bought the original policy?▼

Typically no. It covers work done during the period your original policy was active. Work before you had insurance isn't covered.
