The Coverage Gap Nobody Warns You About
You set up as a sole trader, sorted your HMRC registration, maybe signed up for software that handles Making Tax Digital for Income Tax, and then quietly assumed your existing home insurance had everything else covered. Most people do. It is an easy assumption to make, and it is almost always wrong.
Standard home insurance is written for residential use. The moment you start running a business from your property, even if that only means keeping a laptop and some stock in the spare room, you risk losing parts of your cover without realising it.
This article walks through business insurance for sole traders working from home: what a home policy typically excludes, when a simple add-on is enough, when you need a separate commercial policy, and the point at which cover stops being optional and becomes a legal duty. The employers’ liability section is where home-based businesses are most often given bad information, so it is worth reading even if you are certain it does not apply to you.
What Your Home Insurance Policy Probably Does Not Cover
Before you buy anything new, read your existing policy wording. Not the summary, the actual document. Look for clauses about business use, business equipment and visitors.
Business Equipment
Most home contents policies cover personal possessions, and the word personal is doing a lot of work. A laptop used for streaming and personal email is covered. The same laptop used to invoice clients, run your accounts and deliver work to customers is business equipment in the eyes of most insurers, even though it is the same machine.
Policies vary widely here. Some set a low monetary limit on business equipment, some exclude it altogether, and some will extend cover once you have told them what you do. The limit that applies to you is in your schedule rather than in any article, so check it. If you own a professional camera, specialist tools, design hardware or several devices used for work, there is a real chance that a meaningful amount of kit in your house is uninsured right now.
Stock Held at Home
If you sell physical products and store them at home, standard home insurance almost certainly will not cover that stock. Insurers treat goods held for sale differently from personal possessions. After a fire, a flood or a break-in, your home policy would likely pay out for the sofa and the television but not for the boxes of inventory in the utility room.
Clients or Customers Visiting Your Property
This is the risk sole traders overlook most often. If a client visits your home for a meeting and slips on an icy path, trips over a cable in your office or is injured in any other way on your property, your home policy will almost certainly not respond to a compensation claim arising from your business. Public liability cover is a business insurance product and it is bought separately.
The same applies if you are a therapist, tutor, personal trainer or any other professional who sees clients at home. Once a member of the public is on your property in a business capacity, residential cover is not designed to protect you.
Business-Related Liability Claims
Professional indemnity, sometimes called professional liability, will not feature in a home policy at all. If you give advice, produce creative work, provide consultancy or offer any professional service, and a client suffers a financial loss they attribute to your work, that sits entirely outside residential cover.
When a Home Insurance Add-On Is Enough
Once you have read the wording you may find you are closer to adequate cover than you feared. Not everyone needs to start again from scratch.
Light Administrative Use
If your business activity at home is genuinely administrative, meaning you use a home office for paperwork, calls and email, you meet clients elsewhere, you hold no stock and you employ nobody, many insurers will add business use to your existing policy for a modest extra premium. It is sometimes sold as a home office extension or a business use add-on.
An add-on of this kind typically lifts the equipment limit a little and records the business use of the property without changing the structure of the policy. Ring your insurer, be straightforward about what you do, and ask them to confirm in writing what is included and what is excluded.
Equipment Slightly Above the Standard Limit
If the only gap is that your equipment is worth more than the default limit, a targeted equipment or all-risks extension may close it without a separate commercial policy. Again, ask your existing insurer first.
When You Need a Separate Commercial Policy
Some triggers almost always mean standalone business cover rather than a top-up.
You Hold Stock at Home
Any sole trader selling physical goods from a home address needs stock cover, which is a commercial product. Policies marketed at home-based businesses often bundle stock, equipment and public liability together.
Be honest about the maximum value you would hold at any one time, and think seasonally. If you build up inventory before Christmas or take periodic large orders, your sum insured needs to reflect the peak rather than the average.
Clients or Customers Visit Your Home
If anyone comes to your home in a business context, public liability is the minimum. It covers compensation claims where someone is injured on your property, and damage to a client’s property while they are with you. Cover is typically offered at one, two or five million pounds, and higher limits are common where you see several clients a week or work in a physical setting where accidents are more likely. Some clients and trade bodies will specify a limit before they will work with you.
Your Equipment Is Worth More Than the Home Policy Will Cover
If the total replacement value of your laptops, cameras, instruments, tools or machinery exceeds your home policy’s limit for business items, you need dedicated business equipment cover. Some specialist home business policies include it; otherwise a standalone equipment or tools policy will do the job. Work from your own inventory and replacement values rather than a rule of thumb.
You Employ Anyone in the Business
Employing someone is the point at which insurance stops being a judgement call. The detail matters enough that it has its own section below.
You Run a Higher-Risk Business
Food production, physical therapies, children’s services and anything involving manufacturing carry higher liability exposure, and a standard home business add-on is rarely sufficient. Use a broker who knows your sector.
Employers’ Liability: What the Law Actually Says
Employers’ liability insurance is compulsory under the Employers’ Liability (Compulsory Insurance) Act 1969 for employers carrying on a business in Great Britain. If you employ someone in your business, whether full time, part time, casual, temporary or for a single day, you need it. The policy must provide at least five million pounds of cover and must be with an insurer authorised by the FCA and PRA, although in practice most policies are written at ten million.
The Family Exemption Runs One Way Only
There is an exemption for family businesses, and it is narrower than most people assume.
If your business is unincorporated, meaning a sole trader or a partnership, and every person you employ is a close relative, the Act does not require you to hold cover. The Health and Safety Executive lists close relatives as husband, wife, civil partner, father, mother, grandfather, grandmother, stepfather, stepmother, son, daughter, grandson, granddaughter, stepson, stepdaughter, brother, sister, half-brother and half-sister.
Two limits on that exemption matter. It applies only while every employee is on that list, so taking on one person outside it brings the whole business back into the requirement. And it does not apply to limited companies at all, even where every employee is family. If you have incorporated, the family exemption is simply not available to you.
Being exempt is also not the same as being protected. The exemption removes the duty to insure; it does not remove your liability if a relative is hurt while working for you. Where family members lift, pack, drive or handle tools, cover is usually inexpensive and worth holding regardless.
If You Have Incorporated
A company is exempt where its only employee also owns at least half of the issued share capital, which is the usual position for a one-person limited company. Where two directors each hold fifty per cent, the position is contested: the HSE wording is written in the singular, while specialist insurers take the view that cover is required regardless of the split. The safe assumption is that you need it.
Domestic Help Is a Separate Question
The 1969 Act attaches to employers carrying on a business, so someone you employ purely for the household, such as a cleaner or a gardener with no involvement in your work, is a different case, and many home insurance policies already include employers’ liability for domestic help. If the same person also works in the business, packing orders or answering customer email, the business duty applies and you should treat them as an employee of the business.
Penalties and Certificates
You can be fined up to two thousand five hundred pounds for each day you are without cover when the law requires it, and up to one thousand pounds for failing to display the certificate or produce it when an inspector asks. Certificates can be made available to employees electronically rather than pinned to a wall.
One myth worth retiring: the rule requiring employers to keep old certificates for forty years was revoked on 1 October 2008. Keeping them remains sensible, because disease claims can surface decades after the exposure, but it is no longer a legal requirement.
What Else Employing Someone Triggers
Employers’ liability is the insurance consequence. There are administrative ones too, and they arrive quickly.
You need to register as an employer with HMRC before the first payday. You cannot register more than two months in advance, and you should allow four to six weeks for the PAYE reference to come through. If it has not arrived by payday, pay the employee on time and submit the Full Payment Submission late rather than delaying their wages.
Payroll then runs on Real Time Information, which is a separate regime from Making Tax Digital. A Full Payment Submission goes to HMRC on or before each payday. PAYE and National Insurance are due by the 19th of the month if you pay by post and the 22nd if you pay electronically, and you can pay quarterly if your average monthly liability is under one thousand five hundred pounds.
On the employment law side, a written statement of employment particulars is due on or before the employee’s first day, and payslips must be issued on or before payday and must show hours worked where pay varies with hours. Since 6 April 2026, statutory sick pay has been payable from the first day of absence, with the three waiting days and the lower earnings limit test removed, and both paternity leave and unpaid parental leave are day-one rights. If your first hire is part time or casual, those changes make a difference to what you owe from week one.
Practical Steps to Take Now
- Read your existing home insurance wording, looking specifically for business use, business equipment and visitor clauses.
- List your business equipment and its replacement value honestly.
- Work out whether clients ever come to your home address, even occasionally.
- Work out whether anyone helps you in the business at your property, family or otherwise, and whether your business is incorporated.
- Contact your existing insurer, explain the situation, and ask what is covered, what is excluded and which add-ons exist.
- Get quotes for specialist home business cover if an add-on will not close the gap. Brokers and digital platforms such as Simply Business and Superscript quote across a panel of insurers, and it is worth comparing more than one.
- Confirm everything in writing. A phone conversation is not much use at claim stage.
FAQ
Does working from home invalidate my home insurance entirely?
Not necessarily, but the risk is real. Most policies require you to notify the insurer of any material change in circumstances, and starting a business at the property is a material change. Failing to tell them can put an unrelated claim at risk. Tell them what you are doing and get written confirmation of how it affects your cover.
I only use my home as a registered business address. Do I still need to tell my insurer?
If no business activity takes place at the property, no stock is stored there and no clients visit, many insurers will not treat it as a material change. Notifying them in writing anyway costs nothing and removes the argument later.
Is public liability insurance a legal requirement for sole traders?
No. Unlike employers’ liability, public liability is not required by law for most sole traders. Some clients will insist on it before they contract with you, some trade bodies and licensing regimes require it, and working without it while clients visit your home is a serious exposure. For most home-based sole traders it is inexpensive enough to simply hold.
My spouse helps out. Do I need employers’ liability?
If you are a sole trader or partnership and every person you employ is a close relative, the law does not require you to hold cover. If you have incorporated, it does, even where the only employee is your spouse. And in either case the exemption does not extinguish your liability if they are injured, so consider cover on its merits rather than on the legal minimum.
Can I claim business insurance premiums as a tax-deductible expense?
Yes. Insurance taken out wholly and exclusively for business purposes is an allowable expense for a sole trader. Keep the premium records with the rest of your business records; sole traders should keep records for five years after the 31 January filing deadline for the tax year concerned. If your qualifying income, meaning gross income before expenses from self-employment and property, is above fifty thousand pounds, you have been in Making Tax Digital for Income Tax since 6 April 2026, which means quarterly updates and a Final Declaration submitted through compatible software.
Business Insurance for Sole Traders Working From Home: The Bottom Line
Standard home insurance was not built with your business in mind, and for many sole traders working from home the gap between assumed cover and actual cover is wide.
The fix is usually straightforward. Read the policy, call the insurer, and if your situation involves stock, client visits, equipment above the policy limit or anyone working for you, put proper business cover in place. If you employ anyone in the business and you are not within the narrow family or sole-shareholder exemptions, employers’ liability is not a decision, it is a legal duty with a daily penalty attached.
