Business insurance in the UK: the cover that’s easy to overlook until you need it

A report published by the Association of British Insurers in January 2026 put a number on something brokers see every week: only around half of UK SMEs have employers’ liability insurance in place, despite it being a legal requirement for almost every business with staff. Business insurance rarely makes anyone’s list of exciting topics. But the businesses that get caught without the right cover usually wish they’d looked at it sooner.

In this article, we’ll look at what business insurance actually covers, which policies are legally required, how much cover is enough, and the practical steps to make sure your protection matches the business you run today – not the one you started.

What business insurance actually covers

Business insurance isn’t one product. It’s a collection of separate policies, each built to protect against a different risk – a customer injured on your premises, an employee off work after an accident, a fire that guts your stockroom, a data breach that locks you out of your own systems. Which of these matter to you depends on what your business does, how big it is, and who it deals with day to day.

Public liability insurance: the one most people think of first

Public liability covers claims from members of the public – customers, suppliers, passers-by – for injury or property damage caused by your business. It typically pays out for medical costs and loss of earnings if someone is hurt, the cost of repairing or replacing damaged property, and legal defence costs if a claim goes to court.

It doesn’t cover everything, though. Employee injuries fall under employers’ liability, not public liability. Claims about professional advice or a service gone wrong sit with professional indemnity. And problems caused by a product you’ve made or sold are usually a matter for product liability.

Any business with public interaction – a shop, a trade counter, a site visit to a client’s premises – is exposed here. From experience, the level of cover that makes sense varies a lot by trade and footfall, so it’s worth talking through with a broker rather than guessing.

Employers’ liability insurance: the one the law requires

If you employ anyone, employers’ liability insurance isn’t optional. The Employers’ Liability (Compulsory Insurance) Act 1969 requires most employers to hold at least £5 million of cover, and the Health and Safety Executive can fine a business up to £2,500 for every day it goes without it.

Yet the ABI’s January 2026 research found that only around half of SMEs actually have this cover in place – a gap that’s easy to explain (renewals lapse, new hires get missed) but expensive to discover after the event. Workplace illness alone costs employers an average of £4,800 per case, rising to over £10,000 where the worker is off for more than a week, according to HSE figures.

Professional indemnity insurance: cover for advice and services

If your business gives advice, designs something, or delivers a service rather than a product, professional indemnity insurance protects you against claims of negligence or an inadequate job – covering legal defence costs, compensation, and the financial losses a client says they’ve suffered as a result of your work. For consultants, advisers and anyone billing for expertise, this is often the policy that matters most, even though it’s rarely the first one people think of.

Property, stock and business interruption cover

Property insurance protects your buildings and their contents – equipment, stock, fixtures – against events like fire, theft or storm damage. Business interruption cover works alongside it, replacing lost income if an insured event stops you trading.

This is where the ABI’s research flags a real gap: of the SMEs with physical premises, only around a third have buildings insurance and less than a quarter have business interruption cover. A fire or flood is bad enough. Losing weeks of trading on top of it, with nothing to bridge the gap, is often what actually threatens a business’s survival.

Cyber liability insurance: no longer a niche extra

Cyber insurance covers the costs of a data breach or cyber attack – recovering lost data, managing the incident, and the legal and compensation costs that can follow. Government figures show that 43% of UK businesses reported experiencing a cyber security breach or attack in the past year, and insurers paid out £197 million in cyber claims in 2024, a 230% increase on the year before. This isn’t a large-company problem anymore; it’s a live risk for businesses of every size, and cover is worth a proper look even for firms that have never thought of themselves as a target.

Product liability and key person cover: worth a conversation, not always a given

If you manufacture or sell physical products, product liability insurance covers claims where something you’ve sold has caused injury or damage. And if your business depends heavily on one or two people – a founder, a technical lead – key person insurance provides financial cover if that person dies or is unable to work. Neither is universal, but both are worth a conversation if they apply to how you operate.

How much cover do you actually need?

There’s no single right answer here – it depends on your size, sector, number of employees and the risks specific to how you trade. But two things are worth being honest about.

First, having insurance and having enough insurance are not the same thing. Research published in 2025 found that 88% of commercial sites surveyed were underinsured on their building values – meaning that even where cover exists, a claim may only be partially paid because the sums insured no longer reflect what it would actually cost to rebuild or replace. Rising build costs, wage inflation and growing stock values all erode a policy quietly, year on year, if nobody checks.

Second, cover has a habit of falling out of date. The ABI’s research found that only around half of SMEs had reviewed their insurance in the past year – which means, for the rest, the policy in place was set for a business that may have since taken on more staff, moved premises, bought new equipment or started selling in new ways.

Business insurance works a bit like a fire extinguisher: you hope you never need it, but the day you do is not the day to discover it was the wrong size for the fire.

When to review your policy

A few moments are worth treating as a natural prompt to check your cover:

After any significant change to the business – new premises, more staff, new equipment, a new product line, or trading in a new way.

When legislation changes in a way that affects your risk or your legal obligations.

At least once a year, even if nothing obvious has changed – costs move, and a policy priced against last year’s figures can quietly stop being enough.

What happens if you get it wrong

The consequences of inadequate cover tend to show up at the worst possible moment – when you’re already dealing with a loss. Without liability cover, a claim can mean significant legal fees and compensation paid directly out of the business. Without property cover, storm or fire damage becomes a repair bill you fund yourself. And without business interruption cover, the income lost while you’re not trading has nowhere to come from.

None of this is meant to alarm – it’s meant to make the case for checking, properly, once a year.
