Business Insurance for Consultants UK: What You Actually Need

Raj had spent eleven years in corporate HR before going out on his own, and his first big contract as a consultant felt like the moment it all paid off. Then the procurement email landed: “Please supply certificates for professional indemnity (£1m), public liability (£5m) and employers’ liability within five working days, or the start date will move.” He had none of them. He’d assumed insurance was something for builders and dentists, not a man with a laptop and a good reputation. Consultant insurance in the UK isn’t about the law — it’s about the contract — and this guide walks through exactly what you need, what you can skip, and what it costs in 2026.

Consultant Insurance at a Glance

Cover	Do you need it?	Typical 2026 cost
Professional indemnity	Almost always — most client contracts demand £1m	£300 – £750 a year
Public liability	Yes if you visit client sites or have visitors	£60 – £120 a year
Employers’ liability	Legally required once you employ anyone	Included in most packages
Cyber and data	Strongly advised if you hold client data	£15 – £25 a month
Legal expenses	Worth it for contract disputes and HMRC enquiries	£50 – £150 a year
Portable equipment	Optional — laptop, phone, tablet	£20 – £60 a year

Start With the Contract, Not the Insurer

Most guides start by listing policies. The smarter starting point is the piece of paper that will actually decide what you buy: your client’s contract or supplier questionnaire. Corporate clients, agencies and public bodies almost all carry a standard clause — typically £1 million of professional indemnity, £1 million to £5 million of public liability, and an employers’ liability certificate if you have staff. Agencies and umbrella companies often won’t process your first invoice without proof. Raj’s £5 million public liability demand was simply a template written for every supplier, from cleaners to consultants. Read the clause before you get quotes, because buying £250,000 of PI when the contract says £1 million is money wasted twice.

Professional Indemnity: The Policy You’re Really Being Asked For

Consulting is selling advice, and advice can be wrong. A restructuring plan that triggers an unfair dismissal claim, a marketing strategy that misses the launch window, a financial model with a broken formula, a confidential file emailed to the wrong person — each is a potential claim that you caused your client financial loss. Professional indemnity insurance pays the compensation and, crucially, the legal defence costs, which mount up even when the claim is nonsense. Limits run from £50,000 to £5 million, with £1 million the standard contract ask, and brokers price low-risk consultants at roughly 50p to £1.20 per £100 of fee income — £300 to £750 a year for most. It works on a “claims-made” basis, so keep it running, and buy run-off cover when you stop consulting. Our guide to professional indemnity insurance costs by profession has the full price table.

Public Liability: Small Premium, Big Door-Opener

A consultant’s public liability risk is genuinely low — you’re not on a roof — which is exactly why it’s cheap. It covers injury or property damage you cause to third parties: knocking a client’s monitor off a desk during a workshop, a visitor tripping over your laptop bag in a co-working space, a coffee over a client’s keyboard. Consultants sit at the bottom of the pricing range, typically £60 to £120 a year for £1 million to £2 million, and insurers often bundle it with PI for less than the two would cost separately. Councils, NHS trusts and large corporates often want £5 million before you set foot on site. See our public liability insurance cost guide for what different businesses pay, and how public liability and professional indemnity differ.

Employers’ Liability: The Legal One

This is the only policy on the list the law requires, and it catches consultants in a specific way. The moment you pay someone who isn’t close family under a contract of service — an assistant, a researcher, a junior consultant — you need at least £5 million of employers’ liability cover, or face a fine of up to £2,500 a day. Two common traps: the “associate” you pay a day rate and control like an employee may count as one in the eyes of the HSE, whatever the invoice says; and if you trade as a limited company with two directors, even spouses, you need it from day one. A sole director owning at least half the shares is exempt. Our employers’ liability guide covers every exemption.

Cyber and Data: The Cover Consultants Skip Until a Laptop Goes Missing

Think about what’s on your laptop right now: a client’s salary spreadsheet, a customer database, a board paper marked confidential. Lose it on a train or click a convincing invoice email and you’re looking at breach costs, a possible Information Commissioner’s Office investigation, and an awkward call to the client. Under UK GDPR, qualifying breaches must be reported to the ICO within 72 hours, and most consultants should be paying the ICO’s data protection fee — £52 a year for small businesses. Cyber insurance covers the response costs, legal advice, ransomware and client claims; a consultant turning over £100,000 can find basic cover for £15 to £25 a month. We’ll go deeper in our guides on cyber insurance for small businesses and GDPR for small businesses.

The 2026 IR35 Change and Why Legal Expenses Cover Matters

Here’s something that changed this year and barely made the headlines. From 6 April 2026, the “small company” thresholds that exempt clients from the off-payroll working rules rose sharply — turnover up to £15 million and balance sheet up to £7.5 million, against £10.2 million and £5.1 million before. HMRC estimates around 14,000 more companies now count as small, and when your client is small, your company decides your IR35 status and carries the tax risk if HMRC disagrees. That makes two things more valuable: a proper written contract, and legal expenses cover that pays for an HMRC enquiry or a contract dispute. Our forthcoming guide to IR35 rules for contractors unpacks the status tests.

What a Consultant Actually Pays in 2026

The headline prices are tiny — Simply Business quotes consultant insurance from £7.58 a month, Markel from £5 — but those apply to the cheapest 10% of customers. Real examples tell the story better: a sole-trader training consultant in Manchester paying £23.39 a month, about £234 a year, for a package of PI, public liability and equipment; a training consultancy with two employees paying £52.06 a month, around £521 a year, once employers’ liability is added. Raj, an HR consultant with no staff, ended up at £31 a month for £1 million PI, £5 million public liability and cyber cover. Add 12% Insurance Premium Tax to any quote you compare, and remember that whether you trade as a limited company or sole trader barely moves the price — your fee income and what you advise on do.

Five Mistakes That Leave Consultants Uninsured

The claims that get refused almost always trace back to one of five errors. Describing your work too narrowly — “training” on the policy when you also give HR advice — so the claim falls outside the activities covered. Letting PI lapse between contracts, which under the claims-made rule leaves old work uninsured. Under-declaring fee income to trim the premium, which is misrepresentation. Policies in the wrong legal name after incorporating. And assuming a client’s insurance protects you — it protects them. Freelancers face the same list — our freelancer liability guide fills in the rest.

The Bottom Line

Raj got his certificates in three days, the start date held, and the contract was worth forty times what the insurance cost. That’s the real arithmetic of consultant insurance in the UK: it’s not a defence against disaster so much as the price of admission to the clients worth having. Read the insurance clause in your next contract before you do anything else, buy the limits it names, make sure your cyber cover matches the data you actually hold — and then get back to the work you’re good at.

Frequently Asked Questions

What insurance does a consultant need in the UK?

Professional indemnity is the core policy, usually £1 million to satisfy client contracts, plus public liability for site visits. Employers’ liability becomes legally required once you employ staff.

How much does consultant insurance cost?

Headline prices start around £5 to £8 a month, but a typical sole-trader consultant pays £230 to £400 a year for PI, public liability and equipment cover combined.

Is professional indemnity insurance a legal requirement for consultants?

No, unless you belong to a regulated profession. It’s a contractual requirement — most corporate, agency and public-sector clients insist on £1 million before you start work.

Do consultants need cyber insurance?

If you hold client data on a laptop or in the cloud, yes. It covers breach response, ICO investigations and client claims, and costs around £15 to £25 a month for small consultancies.

Why does IR35 matter for consultant insurance?

From April 2026 more clients count as “small”, so consultants decide their own IR35 status and carry the tax risk. Legal expenses cover and your own PI policy help manage that.
