Will My Professional Indemnity Cover My Past Work?
Professional indemnity insurance protects you from claims arising from your professional services. But what if a client complains about work you completed years ago, before your current policy started? Whether you’re covered depends entirely on your policy’s retroactive date.
Understanding this feature is essential if you’ve switched insurers, had a gap in cover, or taken out a new policy after trading for several years.
What Is a Retroactive Date?
The retroactive date is the earliest date from which your professional indemnity policy will cover past work. It establishes how far back your protection extends.
Example:
- Policy start date: 1 March 2025
- Retroactive date: 1 March 2020
- You’re covered for claims made during the policy period, even if the work was completed between 2020 and 2025
If your policy sets the retroactive date to your policy start date (or has no retroactive date at all), you have no cover for work completed before that date. This leaves you exposed to claims from previous projects.
What Does Retroactive Date Mean in Professional Indemnity Insurance?
Professional indemnity operates on a ‘claims-made’ basis. The policy in force when a claim is made (not when the work was done) is the one that responds.
Your retroactive date creates a boundary:
- Work completed after the retroactive date: covered
- Work completed before the retroactive date: not covered
Most professionals need full retroactive cover, especially if you’ve been trading for years. Claims can surface long after a project finishes, sometimes when defects emerge or advice proves incorrect.
Retroactive Date Meaning in Insurance: Why It Matters
The retroactive date protects you from historic liability. Without it, you’re vulnerable to claims arising from any work completed before your current policy started.
This matters because:
- Design defects may only become apparent years later
- Contractual disputes can arise long after project completion
- Professional advice may be challenged when circumstances change
- Clients have up to six years (sometimes longer) to bring a claim under contract law
If your retroactive date doesn’t cover your full trading history, you could face a claim with no insurance in place.
What Happens When You Switch Insurers?
When changing insurers, your new policy should carry forward your existing retroactive date. Most insurers will agree to this if:
- You’ve maintained continuous cover without gaps
- You declare all material facts honestly
- There are no outstanding claims or circumstances
If there’s been even a single day’s gap in cover, your new insurer may refuse to backdate cover or reset the retroactive date to the start of your new policy. This removes protection for all your previous work.
What If I’ve Had a Gap in Cover?
Cancelling or letting your professional indemnity insurance lapse creates a break in continuity. This is a serious risk.
When you have a gap in cover:
- You lose protection for any claims made during that gap, regardless of when the work was done
- A new insurer will typically set the retroactive date to your new policy start date
- Years of past work become uninsured
This commonly happens when sole traders or consultants pause work to save money. But if a client makes a claim about a project from two years ago and you cancelled your policy in the meantime, you have no cover.

Unlimited Retroactive Cover
Some policies offer unlimited retroactive cover, meaning there’s no cut-off date. You’re covered for all work completed before your policy started, provided you maintained continuous insurance.
This is ideal for most professionals, particularly those who’ve been in practice for many years. It eliminates uncertainty about whether historic projects are covered.
How to Check Your Retroactive Date
Your policy schedule or certificate of insurance should clearly state your retroactive date. Look for wording such as:
- “Retroactive date: Unlimited” (best case)
- “Retroactive date: 01/04/2018” (acceptable if it matches your trading history)
- “Retroactive date: Policy inception” or “None” (no cover for prior work)
If it’s unclear, contact your insurer or broker immediately. Don’t assume you’re covered. You can also review Understanding PI Policy Wording Before You Buy for guidance on interpreting your documents.
Which Professions Are Most Affected?
Claims can arise years after a project completes. The following professions should pay close attention to retroactive dates:
- Architects and architectural technologists
- Surveyors and building consultants
- Engineers and structural designers
- Solicitors and legal advisers
- Accountants and tax specialists
- IT consultants and software developers
- Marketing and design agencies
For design professionals, defects may only become apparent once a building is occupied or after adverse weather. For advisers, the consequences of poor advice may not surface until a transaction fails or a dispute arises.
What If I’ve Had a Lapse in Cover?
If you’ve had a break in your professional indemnity insurance, your options are limited:
- A new insurer will typically set the retroactive date to the start of your new policy
- You won’t have cover for claims arising from work done before that date
- You may be able to negotiate terms if the gap was very short and no claims have arisen
In rare cases, you might be able to purchase retroactive cover for an additional premium, but this depends on your claims history and the insurer’s appetite.

Run-Off Cover and Retirement
If you’re planning to retire or close your business, you’ll still need protection. Run-off cover (also called extended reporting period cover) protects you from claims made after your policy ends, for work done while you were insured.
This is essential because:
- Claims can be made years after you stop trading
- You remain personally liable, even in retirement
- Some professions require run-off cover by regulation
Run-off policies are typically purchased for a fixed period (often six years) and cost a multiple of your annual premium.
Get the Right Cover for Your Past Work
Your retroactive date is one of the most important features of your professional indemnity policy. Get it wrong and you could face a claim with no cover in place.
Before renewing or switching insurers, check:
- Your current retroactive date
- That your new policy carries it forward
- That you’ve had no gaps in cover
