Quick answer: how much does professional indemnity insurance cost in the UK?
For many small UK businesses, professional indemnity insurance can start from around £100–£300 per year for low-risk consultancy with modest limits. Higher-risk sectors (complex IT, regulated advice, design/engineering, high-value projects, or larger contracts) can cost significantly more, especially as your cover limit increases.
The fastest way to see real pricing is to quote with accurate details — role, activities, turnover, contract size, and required limit: Start a PI quote.
PI price is driven by the potential size of a financial loss claim your work could create. If your work can cause downtime, missed revenue, compliance penalties, rework, or failed delivery, insurers price that differently than general low-risk advice.

Typical PI cost ranges (by business type)
PI pricing varies, but having “orientation ranges” helps you sanity-check quotes. The ranges below are not guarantees — they’re a practical way to understand where you might sit depending on your activity and risk profile.
| Business type | Common PI limit | Indicative annual cost | What drives pricing |
|---|---|---|---|
| Low-risk consultants | £100k–£250k | £100–£350 | Advice scope, contract size, claims history |
| IT contractors | £250k–£1m | £150–£700+ | Systems impact, downtime exposure, deliverables |
| Agencies (marketing/design/dev) | £250k–£1m | £200–£1,200+ | Client budgets, deliverables, subcontractors |
| Higher-risk professional services | £500k–£2m | Varies widely | Regulation, high-value projects, specialist advice |
| Small firms (multi-staff) | £1m+ | Varies widely | Headcount, turnover, contractual liabilities |
If your PI is for general consulting, use: PI for Consultants (UK).
If your PI is for IT contracting, use: PI for IT Contractors (UK).
Two “IT contractors” can mean very different risk: a front-end contractor on internal tooling vs someone leading a migration for a revenue-critical platform. Same job title, different claim severity exposure — different pricing.
What affects PI premiums the most?
If you want to predict PI cost before quoting, focus on the drivers insurers care about. These are the levers that usually move price the most.
1) Your activities (what you actually do)
Insurers price based on scope: advice, design, coding, architecture, security, data handling, regulatory guidance, implementation, project leadership, or specialist services. The more your work can lead to financial loss, the more price can move.
2) Contract size and client type
Large contracts, enterprise clients, and high-value deliverables often require higher limits and tighter contract terms. Those requirements can increase price, but they also tell you what cover you likely need to be “contract-ready”.
3) Your turnover (and sometimes fee income)
Turnover matters because it’s a proxy for volume of work and exposure. But it’s not everything — a low-turnover specialist can still have high-severity exposure.
4) Claims history
Prior allegations, disputes, or claims can increase premiums. Even small incidents can shape underwriting if they show a pattern.
5) Your cover limit and policy features
Higher limits generally cost more, but the jump isn’t always linear. The wording, endorsements, and extras also matter (see “Add-ons” section).
- Work type: advice-only vs deliverables that can break systems/revenue
- Contract value: bigger SOW = higher potential loss
- Client type: SMEs vs enterprise/public sector
- Limit required: £100k, £250k, £1m, £2m, £5m
- Territory: UK only vs worldwide
- Claims history: disclosed circumstances matter
How cover limits change PI price (and what limits are common)
Your PI limit is the maximum the insurer will pay for covered claims (subject to policy terms). Many buyers choose a limit based on contract requirements. If you’re not sure, a practical approach is to match the client minimum, then price one tier above to see the uplift.
| PI limit | Typical fit | Cost impact | Notes |
|---|---|---|---|
| £100k–£250k | Lower-risk consulting / small contracts | Often lowest cost band | May not satisfy agencies or enterprise onboarding |
| £500k | Mid-risk work or bigger clients | Moderate uplift | Common stepping stone for growing contractors |
| £1m | Common “contract-ready” level | Often notable uplift | Frequently requested by agencies/clients |
| £2m–£5m | Enterprise/public sector / high-severity | Can increase significantly | Required when potential financial loss is large |
If your work can cause significant downtime, revenue loss, or compliance penalties, a higher limit can be sensible even if not explicitly required. But don’t guess — compare at two limits to see the true uplift.
Claims-made pricing: retroactive date + run-off (why continuous cover matters)
Many PI policies operate on a claims-made basis. That means the policy responding is typically the one in force when the claim is made (not necessarily when the work was done). This affects pricing and purchasing decisions in a big way.
Retroactive date (the “how far back” line)
The retroactive date can define how far back your work is covered. If you have been trading for years, you usually want your PI to cover past work too. Continuous cover helps keep that protection in place.
Run-off cover (when you stop trading or stop contracting)
If you stop trading but a claim appears later, you may still need protection. Run-off is the concept of maintaining cover after trading ends. It can matter for contractors finishing a big engagement and moving away from that risk.
If you let PI lapse and restart later, you can create gaps. That can be more expensive or harder to place — and it can create coverage issues. Continuous cover is often the simplest “stay protected” strategy.

Excess: saving money without creating pain
Your excess is what you pay towards a claim before the insurer pays (subject to policy terms). A higher excess can reduce premium, but it can also create a cashflow problem if a dispute occurs.
If you have predictable cashflow and your disputes tend to be lower value, a moderate increase can lower premium sensibly.
If a single client dispute could be expensive to defend, too-high excess can make PI feel “unusable” when you need it.
Add-ons that change PI price (and when they matter)
PI isn’t always one simple product. Policies can include (or exclude) extensions that matter for certain business models. These features can change price significantly — sometimes worth it, sometimes not needed.
Common PI extensions
- Contractual liability / breach of contract cover (wording varies; can matter if your contracts are strict).
- IP infringement cover (common concern for agencies, marketing, design, software).
- Loss of documents / data-related extensions (varies; may matter where data handling is high).
- Worldwide territory (important if you work for non-UK clients).
- Subcontractor cover (if you use freelancers).
Don’t pay for global/wide extensions you don’t need — but don’t accidentally exclude your real work. The best PI quote is the one that matches your actual activity and contracts.
If your business is mostly products rather than advice/services, you may need: Product Liability (products), not PI (services). Importer example page: Product Liability for Importers.
How to reduce PI cost without buying weak cover
The cheapest PI policy is not always the best — especially if it fails onboarding or doesn’t match your activity. The goal is to reduce cost while keeping “claim readiness” and contract compliance.
1) Describe your activities accurately (and narrowly)
Be clear about what you do and what you don’t do. Vague descriptions can push insurers into conservative pricing. But don’t understate risk — that can cause disputes later.
2) Choose a sensible limit (match contracts, then compare)
If your client requires £1m, buying £250k may be pointless. Conversely, if you only need £250k and buy £5m “just in case”, you can inflate premium unnecessarily.
3) Keep a realistic excess
A slightly higher excess can reduce premium, but “too high” creates cashflow pain. Balance the trade-off.
4) Improve contracts and documentation
Clear scope, written acceptance criteria, and change control reduce disputes. Lower dispute frequency can help over time. For IT contractors, see: PI for IT Contractors.
- Written scope and deliverables for every job
- Change requests logged and approved
- Handover notes and client sign-off
- Version control and backups for deliverables
- Clear limitation of liability in contracts (where possible)
How to compare PI quotes properly (avoid the common traps)
Comparing PI is not only about the annual premium. If you buy the wrong wording, your “cheap” policy can become expensive later. Here’s how to compare like-for-like.
Compare these 8 items every time
- Limit of indemnity (same limit across quotes)
- Basis (claims-made details)
- Retroactive date (does it cover past work?)
- Territory/jurisdiction (UK only vs worldwide)
- Excess (match it to compare fairly)
- Activity description (does it fit your services?)
- Extensions (IP/subcontractors/contractual liability)
- Insurer conditions (any special endorsements)

PI vs public liability vs employers’ liability vs product liability (avoid buying the wrong product)
One of the biggest reasons buyers overpay is purchasing the wrong type of liability cover. Here’s the clean explanation:
| Cover | Protects against | Best for | Start here |
|---|---|---|---|
| Professional Indemnity | Financial loss claims from advice/services/deliverables | Consultants, IT contractors, agencies, professionals | PI hub |

FAQs
What is the average cost of professional indemnity insurance in the UK?
There isn’t one average that fits all. Some low-risk consultants may see prices from roughly £100–£300/year for modest limits, while higher-risk work or larger limits can cost more. The best way to know is to compare quotes based on your real activity and contract requirements.
Why is PI more expensive for some IT contractors?
IT contracting risk can involve downtime, data issues, failed deployments, missed deadlines, and financial loss claims. Contractors working on revenue-critical systems, migrations, security or complex projects often have higher severity exposure. See: PI for IT Contractors.
Does a higher PI limit always cost much more?
Not always. Sometimes moving up one tier is a modest uplift, other times it’s a bigger jump depending on risk profile and insurer appetite. A smart approach is to quote at two limits and compare the difference.
Is professional indemnity tax deductible?
Many businesses treat PI as a business expense. If you’re unsure how it applies to your situation, confirm with your accountant.
What happens if my PI policy lapses?
Many PI policies are claims-made. If you lapse and later get a claim, you may have a coverage gap. Continuous cover is often the simplest way to reduce that risk.
Do I need PI and public liability?
Many service businesses only need PI. But if you operate on client premises, host visitors, attend events, or have a physical office/warehouse exposure, public liability can also be relevant. See: Public Liability.
