What 'Adequate and Appropriate' PI Cover Actually Means
Reviewed by Apex Insurance Brokers · Last reviewed 2026-08-05
If you are regulated by a UK body that sets your professional indemnity (PI) requirement as 'adequate and appropriate', you may have gone looking for the magic figure — and found none. That is deliberate. The phrase does not name a limit. It hands you a duty: to look honestly at what you do, what could go wrong, and what a claim might cost, then hold cover that matches. This page explains what that assessment involves and why it differs from a fixed minimum.
Where the phrase comes from
Several UK regulators frame the PI obligation this way rather than mandating a set sum insured:
- Architects Registration Board (ARB) — the Architects Code requires registered architects to have adequate and appropriate insurance cover for themselves, their practice and their employees, so that a client who suffers loss can be compensated.
- Solicitors Regulation Authority (SRA) — while SRA-regulated firms sit under Minimum Terms and Conditions, a freelance solicitor delivering reserved legal activities must take out and maintain indemnity insurance that provides adequate and appropriate cover for their work, judged against the services they provide, their clients and the risks involved.
- Doctors and the GMC context — under the Medical Act, a licensed doctor must have adequate and appropriate insurance or indemnity in place as a condition of practising in the UK. The General Medical Council checks that a suitable arrangement exists; it does not publish a single premium or limit.
The wording varies slightly between bodies, but the logic is identical: the regulator sets the test, not the amount. Always check the current published rules of your own regulator, as the exact obligation and any guidance can change.
'Adequate' and 'appropriate' are two separate tests
It helps to treat the two words as distinct questions, because a policy can pass one and fail the other.
| Test | The question it asks | What it turns on |
|---|---|---|
| Adequate | Is the limit of indemnity large enough? | The size of the worst realistic claim, plus defence costs. |
| Appropriate | Does the policy actually respond to your work? | The scope, wording, exclusions and basis of cover matching your activities. |
A £5m limit is not 'adequate and appropriate' if the policy excludes the very service that caused the claim. Equally, a perfectly worded policy with a £500k limit fails if your typical project could expose you to a £2m loss. Both dimensions have to hold.
What the standard obliges you to consider
Because there is no defined number, the burden shifts to your own reasoning. In practice, a defensible assessment weighs at least the following.
1. Your exposure — the size of a realistic claim
Think about the largest loss a single piece of your work could cause, not your fee for it. A modest fee can sit behind a very large liability: a design error, a missed limitation date, or negligent advice can generate a claim many multiples of what you were paid. Consider the value of the projects, transactions or assets you touch, and remember that defence costs alone can run into six figures on a contested matter.
2. Your contracts — the liabilities you have accepted
Client contracts frequently set a required level of PI cover, and some remove or cap the protections you would otherwise rely on. A contract may specify a minimum limit, extend how long you can be pursued, or require cover to be maintained for years after the work ends. 'Appropriate' cover has to be read against what you have signed up to — it is a common source of underinsurance because the obligation is buried in schedules people skim.
3. Your activities — everything you actually do
Regulators expect the cover to reflect the full range of your services, not just the headline one. If you have added a consultancy line, taken on project management, expanded into a new sector, or started advising in an area outside your core discipline, the policy must be checked against that spread. Cover that was appropriate two years ago can quietly stop being appropriate as the business shifts.

Why regulators avoid a single fixed number
A flat minimum would be simple, but it would also be wrong for most people most of the time — too high for a low-risk sole practitioner, dangerously low for someone advising on high-value schemes. The 'adequate and appropriate' framing lets one rule cover a whole profession while pushing each member to right-size their own protection. It also keeps the duty live: it is not a box you tick once at registration but a judgement you are expected to revisit as your work changes.
The trade-off is that the responsibility sits with you. If a claim exceeds your limit, or your policy does not respond, 'I bought what was cheapest' is not a defence. You are expected to have reasoned about the cover you hold.
How to evidence that you have met it
- Record your reasoning. Keep a short note of how you set your limit — the largest realistic claim, contractual requirements, and the activities the cover has to reach.
- Match the policy to the work. Read the exclusions and the business description on your schedule against what you genuinely do.
- Mind the run-off. PI is typically written on a claims-made basis, so cover must be in force when a claim is made — think about the tail after you stop or change work.
- Review on change, not just at renewal. A new service line, a bigger client, or a demanding contract are all triggers to reassess.

Is there a set minimum for 'adequate and appropriate' cover?
No. Unlike regimes that publish a fixed minimum sum, 'adequate and appropriate' deliberately leaves the amount to you. You judge it against your exposure, contracts and activities. Always confirm the current position with your own regulator, as some professions combine this test with additional published requirements.
Which UK bodies use this wording?
It appears across several regulators, including the Architects Registration Board for architects, the SRA for freelance solicitors carrying out reserved legal activities, and, in the medical context, the GMC's requirement that licensed doctors hold adequate and appropriate insurance or indemnity. The precise wording and any guidance differ by body.
Can cheap cover still be 'appropriate'?
Price is not the test. A low premium is fine if the limit and wording genuinely match your work — but if the policy excludes a key service, caps costs too tightly, or carries a limit below a realistic claim, it fails regardless of what it cost.
