How much is professional indemnity insurance for startups?

Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05

If you are launching a consultancy, design studio, tech firm or any business that gives advice or delivers a professional service, PI insurance is often one of your first cover decisions. The honest answer to “how much will it cost?” is that it depends — but the factors that move the price are predictable, and once you understand them you can budget with confidence and avoid paying for cover you do not need.

This guide explains what actually drives a startup PI premium, walks through the typical cover-limit options, and shows where a broker earns their keep. We deliberately do not quote prices: any figure you see advertised online is a starting point that ignores your real risk profile.

What professional indemnity insurance covers

PI insurance protects your business if a client alleges that your professional advice, service or work caused them a financial loss. It can cover the cost of defending the claim and any damages or settlement you are liable to pay. Typical triggers include professional negligence, errors, breach of duty of care, and in many wordings, defamation or loss of client documents. For a startup, it matters because a single dispute in your first years can cost far more than the annual premium.

The five drivers behind your premium

Insurers price PI on the likelihood and potential size of a claim against you. For a startup, these are the levers that count.

1. Turnover or fee income

This is usually the single biggest factor. Higher expected income signals more clients, more contracts and more exposure — so premiums rise with it. As a new business with modest projected turnover, this generally works in your favour. Be realistic rather than optimistic with your figures: over-stating projected turnover inflates your premium unnecessarily.

2. What your business actually does

Activities carry very different risk weightings. Lower-risk advisory or creative work is priced more keenly than work where an error could cause large, cascading financial loss — for example financial advice, engineering design, or software that clients rely on for critical operations. Two startups with identical turnover can pay very different premiums purely because of what they do.

3. The cover limit you choose

A higher limit of indemnity means the insurer could pay out more, so it costs more. The right limit is not simply the cheapest — it is the amount your contracts and clients require. See the comparison below.

4. Claims and trading history

As a startup you have no claims history, which is neutral rather than negative — you simply have a clean sheet. Insurers may weigh the founders’ relevant experience and qualifications. Established firms with prior claims can pay more, so a clean start is an advantage worth keeping.

5. Sector and client type

Serving highly regulated sectors, large corporates or public bodies typically raises the stakes on any potential claim, which feeds into pricing. Contract terms your clients impose — such as a required minimum limit or specific policy conditions — also shape what you need to buy.

Choosing a cover limit: £1m, £2m or £5m

The limit of indemnity is the maximum your insurer will pay. These are common options rather than fixed tiers — the right figure is driven by your contracts, not a guess.

A frequent startup mistake is buying too little because it looks cheaper, then discovering a key client contract demands more. Check your client agreements and any professional body requirements before you settle on a limit. Tell us what your contracts require and we will match the limit to it.

Other things that affect what you pay

• Excess: agreeing to pay a larger share of any claim yourself can reduce the premium, but only choose an excess you could genuinely afford.
• Retroactive date: most PI is claims-made, meaning it responds to claims made during the policy period. As a startup, your retroactive date usually begins when cover starts — important to keep continuous once you have it.
• Policy add-ons: extensions such as breach of confidentiality or wider legal defence costs can affect the price and are worth reviewing rather than assuming.
• How you present your business: a clear, accurate proposal that explains your activities well helps insurers price you fairly.

How a broker helps you pay the right price

An online quote engine prices you on a handful of tick-boxes. A broker looks at your actual work, matches you to insurers who understand your sector, and makes sure the limit and wording fit your contracts — so you are neither under-insured nor paying for cover you will never use. As a new business, that guidance is especially valuable because you have no renewal history to lean on. At Apex we place your risk with the market and explain the trade-offs in plain English before you commit.

Common questions

Is PI insurance a legal requirement for startups?
Not universally, but many regulators, professional bodies and client contracts make it mandatory. Even where it is optional, most advisory and service startups carry it because a single claim can be existential. Check your sector’s rules and your client agreements.

Will my premium rise as my startup grows?
Typically yes — because turnover and exposure are the main drivers, a growing income usually means a higher premium at renewal. Reviewing cover each year with a broker keeps the limit appropriate as your contracts and client base change.

Can I reduce the cost without cutting essential cover?
Sometimes — for example by choosing a sensible excess, reporting turnover accurately, or presenting your activities clearly to insurers. What you should not do is cut the limit below what your contracts require just to save money. Ask us to review your options.
