Why Getting This Wrong Can Be Costly

You delivered a project, the client paid, and you moved on. Two years later a solicitor’s letter arrives claiming your advice caused your former client a significant financial loss. Whether you are protected at that moment has very little to do with the insurance you held while you were doing the work, and almost everything to do with the policy in force on the day the letter lands.

Professional indemnity insurance for consultants and freelancers is one of the most important covers in UK professional services, and one of the least understood. This guide explains what it covers, how the claims-made basis works, how much cover you are likely to need, and what has to happen to your policy when you stop trading.

What Is Professional Indemnity Insurance?

Professional indemnity insurance, usually shortened to PI, responds when a client claims that your advice, services or work caused them a financial loss. It pays the cost of defending the claim and, where liability is established, the compensation or damages, up to the limit you have bought.

It is a different product from public liability insurance, which deals with bodily injury and property damage, and from employers’ liability insurance, which is a legal duty once you employ anyone in your business. PI is concerned with the quality and accuracy of your professional output.

Who Needs It

PI is most relevant to anyone who earns a living from advice or knowledge-based work. That covers management consultants and business advisers, IT contractors and software developers, accountants, bookkeepers and tax advisers, marketing and PR consultants, architects, surveyors and engineers, graphic, web and UX designers, trainers, coaches and HR consultants, and legal consultants and paralegals.

The test is simple enough. If a client could reasonably argue that something you said or produced cost them money, you are in the market for PI cover.

What Professional Indemnity Insurance Actually Covers

A standard policy for consultants and freelancers will typically respond to claims arising from the following.

Negligent Advice or Services

The most common trigger. A client argues that your advice was wrong, incomplete or fell below the standard expected of a competent professional, and that they lost money as a result. This is the bread and butter of PI claims.

Errors and Omissions

A miscalculation in a report, wrong data in a financial model, a coding error that takes down a client’s system. PI covers mistakes you made and things you failed to include or check.

Breach of Confidentiality

If you disclose sensitive client information through a misdirected email, a security lapse or negligent data handling, and the client suffers harm, PI can respond to the resulting claim.

Note the limit of that. A civil claim by the client is one thing; a penalty imposed by the Information Commissioner’s Office is another. Regulatory fines are excluded by most policies and whether they can lawfully be insured at all in the UK is contested. The investigation and response costs that follow a data breach usually belong to a cyber policy rather than a PI one.

Intellectual Property Infringement

Some policies extend to unintentional infringement of a third party’s copyright, trademark or other IP rights, which matters if you use images, reproduce content or build something that turns out to resemble a competitor’s work. This cover is not universal, so check the wording rather than assuming.

Defamation

Many policies include unintentional defamatory statements made in the course of your professional work, for example in a report or a presentation.

The Mechanic Most People Miss: Claims-Made Cover

Professional indemnity in the UK is almost always written on a claims-made basis, and this is the part that catches people out.

With a claims-made policy, what matters is the cover you hold at the moment a claim is made against you, not the cover you held when you did the work.

Take a consultancy project finished in March 2024, insured at the time. You let the policy lapse the following year because work dried up. In 2026 the former client claims. Under a claims-made policy there may be no cover at all, because the policy that mattered was the one that should have been in force in 2026, and there wasn’t one.

The Retroactive Date

When you take out a new policy, the retroactive date is the earliest date of past work the policy will pick up. If it is set to the start of the new policy, everything you did before that date is uninsured, however diligently you paid premiums to your old insurer.

Switching insurers is therefore not a like-for-like exercise. Ask for a retroactive date that goes back to when you first started trading professionally, or at minimum one that matches the continuity of your previous cover. A cheaper premium with a fresh retroactive date is usually not cheaper at all.

Notification of Circumstances

Most policies require you to notify not only claims but circumstances: anything you become aware of that might give rise to a claim later. Sitting on an angry email until it becomes a formal letter can hand your insurer a reason to decline. Notify early, notify in writing, and do not admit liability or offer a settlement before speaking to your insurer or broker.

Each and Every Claim, or in the Aggregate

Two policies with the same headline limit can differ substantially. An each-and-every-claim policy applies the full limit to each separate claim; an aggregate policy applies one limit across the whole policy year, so a second claim eats what is left of the first. Where a client contract specifies a limit, check which basis it requires, because some specify each and every claim explicitly.

Run-Off Cover: What Happens When You Stop

If you are winding down, retiring or closing a limited company, the claims-made basis creates a real exposure. Your work outlives your business. A client can raise a complaint years after you delivered, and by then there is no live policy to respond.

Run-off cover exists for exactly this. It is a policy taken out when you cease trading that covers claims made after you stop but arising from work done while you were active. Without it you are personally exposed to the full cost of any claim, including defence costs that can run into tens of thousands of pounds even where you did nothing wrong.

How Long You Need It For

The draft answer of three to six years is too short for some consultants, and the reason sits in limitation law rather than in insurance practice.

In England and Wales, the Limitation Act 1980 gives six years for breach of a simple contract, running from the breach, and six years in tort, running from the date the damage occurred. Contracts executed as a deed attract twelve years. Where damage is latent, section 14A allows three years from the date the claimant knew or ought to have known about it, subject to a fifteen-year longstop under section 14B.

Scotland works differently. The Prescription and Limitation (Scotland) Act 1973 sets a five-year prescriptive period, with a twenty-year longstop, and Scots law does not treat deeds as a separate category. Northern Ireland has its own legislation again.

The practical reading for an England and Wales consultancy is that six years is the working minimum rather than the generous option, and that if any client contract was executed as a deed, your exposure runs to twelve.

How Run-Off Works

You arrange run-off at the point you cease trading, usually with your existing insurer, and premiums are typically paid as a lump sum or over a short period, often on a declining scale rather than at full annual rate. Arrange it before you let the policy lapse. Once cover has gone, buying it retrospectively is difficult and sometimes impossible.

Regulated professions have this decided for them. Solicitors’ firms must maintain six years of run-off under the SRA Minimum Terms and Conditions, and the insurer stays on risk for that period. ICAEW firms must hold run-off for at least two years and then take all reasonable steps to keep compliant cover in place for a further four. If you are a member of a professional body, its rules set your floor, not your ceiling.

One trap worth naming: closing the company is not the same as closing the liability. A dissolved company can be restored to the register so that a claim can be pursued against it, and the existence of an insurance policy is often precisely why a claimant applies to do so. Whether you are ceasing self-employment or closing a limited company through a members’ voluntary liquidation or a strike-off, talk to a specialist PI broker before the policy lapses.

How Much Cover Do You Need?

Contractual Minimums

Larger corporates, public sector bodies and financial services firms commonly specify a minimum limit as a condition of contract. One million pounds per claim is a common requirement for general consultancy, two million appears frequently in larger commercial and public sector contracts, and five million turns up in regulated industries and high-value engagements.

Read the clause before you sign. If a client requires two million and you hold five hundred thousand, you are in breach of contract from day one, and that breach is itself uninsured.

Regulatory Minimums

If you are regulated, the number is not yours to choose. Solicitors’ firms must carry at least two million pounds for any one claim, rising to three million for incorporated practices, under the SRA Minimum Terms and Conditions. ICAEW firms in public practice have had a two million minimum since the 2024 changes, with firms under eight hundred thousand pounds of gross fee income required to hold the higher of two and a half times that income or two hundred and fifty thousand pounds. Architects, financial advisers and other regulated roles have their own requirements set by their regulators.

Choosing Your Own Level

Where no minimum is imposed, judge it on the size of the decisions you influence rather than the size of your invoices. Advice that feeds an acquisition, a major IT programme or a compliance decision can generate a claim many multiples of the fee you earned.

Insurers will usually start from your annual fee income, and the ICAEW formula of two and a half times gross fee income is a reasonable sanity check even if it does not apply to you. Consider also how you are structured: a sole trader faces a claim against personal assets, while a limited company puts the company in the firing line first, although directors can still attract personal liability in some circumstances.

What Professional Indemnity Insurance Does Not Cover

• Your own deliberate acts, dishonesty or fraud, although many policies do cover the business for the dishonesty of employees
• Contractual penalties and liquidated damages, unless a specific extension is bought
• Cyber incidents, data restoration and breach response costs, which belong to a cyber policy
• Regulatory fines and penalties
• Employment disputes with your own staff, which sit with employment practices liability cover
• Bodily injury and property damage, which sit with public liability cover

Read the wording and ask your broker to talk you through the exclusions that bite on your particular type of work.

FAQ

Is professional indemnity insurance a legal requirement for UK freelancers?

There is no blanket legal requirement in the way there is for employers’ liability. It is, however, a regulatory requirement for a number of professions, including solicitors, FCA-regulated advisers, architects and accountants in public practice, and it is a contractual condition in a great many client engagements, which has much the same practical effect. Where it is not compulsory, the exposure of doing advice-based work without it is still substantial.

Can I get PI insurance if I work through a limited company?

Yes, and most contractors and consultants operating through their own company take the policy out in the company’s name. Cover follows the business, and a director can still face personal liability in some circumstances, so confirm with your broker that the policy is arranged to match how you actually contract.

What is a retroactive date and why does it matter?

It is the earliest date of past work your current policy will respond to. Work done before that date is uninsured under the new policy even if it was insured at the time. When switching insurers, this is the single most important term to check.

How do I make a claim on my PI policy?

Contact your insurer or broker the moment a complaint, a letter of claim or any circumstance that might lead to one comes to your attention. Do not admit liability, apologise in writing or offer anything to the claimant before you have spoken to them, because doing so can prejudice your cover. Most policies require prompt notification and many require notification of circumstances before any formal claim exists.

I am taking a year out. Can I pause my cover and restart it later?

Not without creating a gap. A claim made during the gap has no policy to respond to, and when you restart, the new insurer’s retroactive date may exclude everything you did beforehand. If you are stopping for a while, ask about run-off or a reduced-premium dormant arrangement rather than cancelling.

Professional Indemnity Insurance for Consultants: The Bottom Line

For anyone selling advice in the UK, PI is not an optional extra, and the claims-made basis is the thing to understand before anything else. It means maintaining cover continuously, handling renewals and switches with the retroactive date in front of you, and arranging run-off at the point you stop trading rather than after.

Work with a broker who knows your sector, check the limit and the basis your contracts require before you sign them, and match the run-off period to the limitation period that actually applies to your contracts rather than to the shortest option on the quote.

This article is general information about insurance and the law in the UK, not advice, and it does not take account of your circumstances. Limitation periods, regulatory minimums and policy wordings vary and change. Speak to an FCA-authorised broker or insurer, and to a solicitor or your professional body, before acting on anything here.
