One of the real advantages of trading as a limited company is that the company, not you personally, carries liability for most business claims. But that protection only goes so far without the right insurance behind it.
For an ecommerce limited company, the risks are varied. You're handling physical goods that could harm a customer. You're storing customer data that could be exposed in a cyberattack. You're sending stock through couriers who can damage or lose it in transit. And if you employ anyone, their workplace claims fall to the company.
This guide covers the main types of cover, what UK law actually requires, the ecommerce-specific risks worth insuring against, and how every premium reduces your corporation tax bill. We've kept the figures to what's verifiable, because insurance pricing varies hugely by trade and is something you should always get a personalised quote for.
What is ltd company insurance and what does it cover? {#what-is-ltd-company-insurance}
Ltd company insurance is a collective term for the business covers a limited company takes out to protect itself from financial losses caused by claims, accidents, or disruption.
The key difference from sole trader cover is that the company is the insured party, not you. Claims are settled against the company's assets, not yours. That said, it doesn't make directors entirely untouchable. Directors can still face personal liability in specific circumstances, which is where directors' and officers' (D&O) cover comes in.
For most ecommerce limited companies, the core policies to weigh up are public liability, employers' liability (if you have staff), product liability, cyber cover, and stock or contents cover.
What insurance is legally required for a UK limited company? {#legally-required}
There's only one type of business insurance that UK law requires you to hold: employers' liability insurance.
If your company employs anyone, you must hold at least £5 million of employers' liability cover from an authorised insurer. You can be fined £2,500 for every day you're not properly insured, and a further £1,000 if you don't display the certificate when asked.
There's a narrow exemption. A company that employs only one person, where that person also owns 50% or more of the issued share capital, generally doesn't need the cover. In practice that's the classic single-director, single-shareholder company with no other staff. The moment you take on an employee, the obligation applies. Note too that the usual "close family member" exemption does not apply to limited companies, only to unincorporated employers. If you're unsure where you stand, check it before you hire.
Everything else, including public liability, product liability, and cyber cover, is optional under UK law. In practice much of it is effectively compulsory, because clients, suppliers, and online marketplaces often require proof of cover before they'll work with you.

Here's a plain-English breakdown of the main policies and what each one does.
Public liability covers claims from third parties (customers, visitors, the public) for injury or property damage caused by your business activities. If someone is injured at your warehouse, or your activities damage a customer's property, this is the policy that responds. Many contracts specify a minimum level.
Employers' liability covers claims from your own staff if they're injured or fall ill because of their work. It's legally required once you have employees.
Product liability matters a lot for ecommerce. If a product you sell injures a customer or damages their property, this cover pays for legal defence and any compensation. Crucially, it can apply even if you didn't make the product. As an online seller, you can be held responsible for goods you sourced from a third-party supplier.
Cyber cover responds to a data breach, ransomware attack, or other cyber incident. If you hold customer payment details, addresses, or order histories, and almost every ecommerce business does, you're a potential target. A breach can trigger investigation costs, customer notification, and a possible fine from the Information Commissioner's Office (ICO).
Business interruption pays out if you can't trade because of an insured event, such as a fire at your warehouse. For lean ecommerce operations with low fixed overheads, assess this carefully rather than including it by default.
Stock in transit and contents cover protects your goods while they're being shipped or stored. A courier's standard liability is often far lower than the value of the goods, so separate cover is worth having if your stock values are significant.
What ecommerce risks should you specifically insure against? {#ecommerce-risks}
Generic insurance guides often miss the risks that are specific to selling online. Here's where ecommerce directors need to pay particular attention.
Product liability claims. This is the big one. If you sell physical goods (beauty products, electronics, clothing, supplements, children's toys), you can be held liable if those products cause harm, even when you bought them from a wholesaler. One serious claim without adequate cover could exceed the company's assets.
Cyber incidents. Ecommerce businesses hold more customer data than most sectors: payment details, addresses, and purchase histories across your platform, CRM, and accounting software. A breach exposing that data can lead to an ICO fine, compensation claims, and the cost of investigating and putting things right.
Delivery and transit damage. A courier's liability under standard terms is usually capped well below the value of high-value goods. If you ship expensive items, stock in transit cover fills the gap between what the courier will pay and what the consignment is actually worth.
Warehouse and fulfilment risks. If you use third-party fulfilment, including marketplace fulfilment programmes, read what your agreement says about liability for lost or damaged stock. Provider liability is often limited, and separate stock cover bridges the shortfall.
Is ltd company insurance tax-deductible? {#tax-deductible}
Yes. Standard business insurance premiums taken out wholly and exclusively for the business are deductible as a business expense for corporation tax. That includes public liability, employers' liability, product liability, cyber cover, business interruption, and stock cover.
The deduction works by reducing your company's taxable profit before corporation tax is worked out. For the financial year from 1 April 2025, the main rate is 25% on profits over £250,000 and the small profits rate is 19% on profits up to £50,000, with Marginal Relief tapering the effective rate in between.
Illustrative example: the tax saving on a £500 premium
Say your company pays £500 a year in combined insurance and you want to see the corporation tax saving.
- A company paying the small profits rate of 19% saves £500 x 19% = £95.
- A company paying the main rate of 25% saves £500 x 25% = £125.
So the same £500 premium reduces your corporation tax bill by between £95 and £125, depending on your profit level. Companies with profits between £50,000 and £250,000 pay somewhere in between, because of Marginal Relief.
Keep your policy schedules and premium receipts in your accounting software and flag them at year-end. If premiums leave the account by direct debit, they can slip through with an unhelpful bank-feed description, so it's worth checking they've been categorised as a business insurance expense rather than missed. Our bookkeeping service handles exactly this kind of tidy-up.
One nuance: D&O insurance, which covers individual directors against personal liability claims, can generally be deductible as a company expense where it's taken out for genuine business purposes. The treatment depends on how the policy is structured, so confirm yours with your accountant.
How does the claims process work for limited companies? {#claims-process}
The process is straightforward, but timing matters. Report any incident to your insurer immediately, not after you've tried to resolve it yourself, and not after a formal letter of claim has landed.
Your insurer appoints a claims handler who manages the process: gathering evidence, liaising with the claimant or their representatives, and negotiating any settlement. As policyholder you're kept informed, but you won't usually handle the legal correspondence yourself.
Keep records at the time of any incident: photos, witness details, relevant invoices or product records, and any communication from the claimant. For product liability claims, batch records and supplier documentation help you show you sourced responsibly. Your insurer typically covers legal costs even for claims that ultimately fail, which is a meaningful protection when professional fees can run into thousands before a case resolves.
How do you choose the right ltd company insurance policy? {#choose-policy}
Start with what's legally required and what your contracts or marketplaces demand, then build from there.
If you have employees, employers' liability is non-negotiable. If a client contract or marketplace agreement sets a minimum public liability level, match or exceed it. Then assess your ecommerce risk profile: do you sell physical products that could harm customers, hold significant stock, or store customer payment data?
Compare quotes from more than one provider rather than accepting the first renewal figure. A few things worth checking before you commit:
- The policy specifically covers the products you sell (some exclude categories such as supplements, electronics, or cosmetics).
- Your cover level meets any contractual minimum.
- Any cyber cover handles both first-party costs (your own investigation and remediation) and third-party claims (customer compensation).
Review your cover every year, ideally alongside your annual accounts. If turnover has grown, you've launched new product lines, or you've taken on staff, last year's policy may no longer be adequate.

FAQs {#faqs}
What insurance does a UK limited company legally need? Employers' liability insurance is the only legal requirement, and only if you have employees. You must hold at least £5 million of cover. Everything else (public liability, product liability, cyber) is optional in law but often essential in practice.
Does a single-director limited company need employers' liability insurance? Generally not, if you're the only person the company employs and you own 50% or more of the share capital. As soon as you take on another employee, the requirement applies. The close-family-member exemption that unincorporated businesses can use does not apply to limited companies.
Is ltd company insurance tax-deductible? Yes. Standard business insurance premiums taken out for the business are deductible against corporation tax, reducing your taxable profit. A £500 premium saves £95 at the 19% small profits rate or £125 at the 25% main rate.
Does public liability insurance cover product claims too? Not automatically. Public liability and product liability are often separate covers, though many combined policies include both. If you sell physical products online, make sure product liability is specifically named in your policy wording.
What cyber cover do ecommerce businesses need? Look for a policy that covers both first-party costs (investigating a breach, notifying customers, restoring systems) and third-party liability (customer compensation after a data breach). Some basic cyber extensions cover only one, so read the wording.
Can I add directors' and officers' cover to my policy? Yes, and it's worth considering for personal protection as a director. D&O cover responds to claims about your management decisions. Premiums are generally deductible as a company expense where taken out for business purposes, but confirm the specific treatment with your accountant.
