Nobody starts a business feeling excited about small business insurance. It sits on the to-do list somewhere below buying a van and above sorting a logo, and it stays there quietly until a letting agent asks for a certificate before you can start work, or a school says no cover means no entry. Then it becomes the most urgent job of the week.
The problem is that the moment you go looking, you get buried. Comparison sites throw eleven add-ons at you. A broker asks about heat work and working at height when all you do is cut hair. Somebody in a Facebook group says you absolutely must have £5 million of cover, and somebody else says they have traded for nine years with none at all.
So here is the plain version: what the law forces you to hold, what your customers will force you to hold, what is genuinely worth paying for, and what you can leave until the business is bigger.
What The Law Actually Makes You Buy
Most small business insurance is not compulsory. There is no law saying a self employed gardener must hold public liability cover. Three types of cover are different, though, because they are set by statute or by a regulator.
Employers’ liability. The moment you employ somebody, even one person part time, even a casual weekend helper, you almost certainly need employers’ liability cover. There is a legal minimum level of cover, penalties for each day you trade without it, and a separate requirement to make the certificate available to staff. The exemptions are narrow, and they trip people up: a limited company with a single director who owns all the shares is usually outside it, but the same person taking on one apprentice is not. The Health and Safety Executive sets out the current rules and cover level, and that is the page to check rather than trusting a forum post.
Motor insurance for business use. If you drive to jobs, your policy needs the right class of use. Social, domestic and pleasure plus commuting does not cover driving between three customers in a day. This is where people get caught: the cover exists, it is just the wrong cover, and it fails at the exact moment you need it.
Cover your regulator or professional body demands. Plenty of trades and professions are told to hold professional indemnity as a condition of registering or being listed. Counsellors, accountants, financial advisers, some fitness instructors under their governing body, gas engineers under their scheme rules. If you belong to a register, read its membership terms before you buy anything, because it may specify a minimum limit.
Public liability is not on that list. It is not legally required. It is simply required by so many customers that the difference stops mattering.
The Cover Most Sole Traders Buy First
Once the legal minimum is out of the way, the small business insurance question is not “what should I have?” but “what would a bad afternoon cost me?”
If You Work On Other People’s Property
Public liability pays out when you injure somebody who is not your employee, or damage property that is not yours. A dropped tile through a conservatory roof. A customer tripping over your cable in their hallway. A flood from a pipe you touched last Tuesday.
Cover limits usually come in £1 million, £2 million, £5 million and £10 million. Do not agonise over which is morally correct. Find out what your customers demand. Councils, housing associations, main contractors, schools and many letting agents publish a required limit, and it is often £5 million for site work and £2 million elsewhere. Buying £1 million to save a few pounds a month, then losing a contract over it, is a false economy.
If You Sell Advice, Words Or Treatment
Professional indemnity covers the cost of getting it wrong with your brain rather than your hands. A bookkeeper who misfiles a return. A consultant whose forecast leads to a bad hire. A tutor, a coach, a copywriter, a therapist. The claim is usually not the client’s injury, it is their money, plus the legal cost of arguing about it, which is often the bigger number.
Your Own Stuff
Tools in a van, a £1,400 laptop, stock in a spare room, a treatment couch, a coffee machine. Home contents policies frequently exclude anything used for business, and vans get emptied overnight in ordinary streets. Tools cover often carries conditions about locks and where the van is parked, so read that part twice. Business equipment at home may be addable to your home policy for a small amount, which is usually cheaper than a standalone policy.
Your Own Income
This is the gap people ignore. If you break your wrist, employers’ liability and public liability do nothing for you, because you are not the third party. Personal accident cover or income protection is the only thing that pays the mortgage while you cannot work. For a sole trader with no sick pay, it can matter more than anything else on the list.
Small Business Insurance You Can Probably Skip For Now
Being blunt about this saves real money. A lot of small business insurance packages are sold with add-ons that suit a company of forty people and do very little for one person with a van.
- Business interruption when you have no premises and no stock. It exists to replace lost trading profit while a shop or workshop is out of action. If you work from customers’ homes, it is buying air.
- Legal expenses cover you already hold twice. Trade body memberships and some bank business accounts include a legal helpline or cover as standard. Check before you buy it again.
- Cyber cover priced like a mid-sized firm. If you hold a customer list and take card payments through a provider, your exposure is real but modest. Read what the policy actually pays for. If it mostly funds a breach response team you would never call, it is not doing much.
- Key person cover in a one-person business. There is nobody left to receive the payout in the way the product intends.
- Product liability when you fit goods rather than make or sell them, though it is worth a direct question to the insurer, because “supply and fit” is a grey area.
None of this is a rule. It is a filter. Every pound you spend on cover you will never claim on is a pound not spent on the cover you might.
What Actually Moves The Price
Two people in the same trade can get small business insurance quotes that differ by a factor of four, and it usually comes down to the same handful of answers. Understanding them is the difference between accepting a number and negotiating one.
The big one is trade classification. Insurers group work by how badly it can go wrong, and small business insurance pricing is brutal about it: a mobile nail technician sits in a very different bracket to a roofer, and a roofer who also does hot works sits in another bracket again. Turnover matters. Number of staff and subcontractors matters. Height, heat and depth all matter, so if you never go above a step ladder or touch a blowtorch, say so clearly, because policies get priced for the worst thing on your list.
Then there is the excess, the cover limit, whether you want legal cover bolted on, and your claims history. Raising the excess from £250 to £500 can shave a useful amount off the premium, as long as you could actually find £500 on the day.
Where To Buy It Without Reading Forty Pages
Three routes to small business insurance, and they suit different people.
Comparison sites and direct online insurers are quick, cheap and fine for low risk work. Get three quotes rather than one, because the same details often produce very different answers, and set them all to the same cover limit and excess so you are comparing like with like.
A broker earns their keep the moment your work is unusual, seasonal, or spread across two trades. Anyone doing electrical work plus a bit of plastering, or running a mobile business alongside a market stall, will get further with a human being than with a dropdown menu. Brokers do not usually charge you a fee for arranging cover, they are paid by the insurer.
Trade bodies and federations sometimes bundle small business insurance into membership. Worth checking the price of membership plus policy against buying the policy alone, because the bundle is not automatically cheaper.
Whichever route you take, answer every question honestly, including the awkward one about past claims or a county court judgment. Non-disclosure is how policies get voided, and a voided policy is worse than no policy, because you paid for it and still have nothing.
Read The Boring Bits Before You Need Them
Four parts of a small business insurance schedule are worth ten minutes with the document in front of you. What is the cover limit, and is it per claim or in total for the year. What is excluded, especially work at height, hot works, and any activity you do only occasionally. Whether professional indemnity is written on a claims-made basis, which means the policy that pays is the one live when the complaint arrives, not the one live when you did the job. And what the excess is on each section, since tools and liability often differ.
That last point about claims-made cover is the one that catches consultants who retire or switch trades. If you stop paying, cover for old work stops too, which is why run-off cover exists.
Small Business Insurance And Actually Winning The Job
Here is the part nobody mentions. Being insured only wins work if the customer knows about it before they call somebody else.
Think about an ordinary week for a self employed painter and decorator quoting three domestic jobs. On at least one of them somebody will ask, or wonder without asking, whether there is cover if a ladder goes through a window. Two of those three homeowners will have looked you up on their phone before you arrived.
So put it in writing where they can find it. One line on your quote template, one line on the page they land on when they search your name: public liability cover to £2 million, certificate available on request. It costs nothing and it removes a doubt you would otherwise have to answer out loud. If you have not got anywhere to put that line yet, a simple small business website is the cheapest place to keep it, alongside your trade registrations and the areas you cover. We keep the way our monthly service works deliberately dull for exactly this reason: most sole traders want four pages that make them look real, not a project.
Records, Renewals And Not Getting Caught Out
Keep every certificate in one place from day one, digital and printed. You will be asked for them at short notice by agents, contractors and occasionally a customer’s insurer, and hunting through email attachments on site is a miserable job.
Put the renewal date in your diary with a reminder three weeks early, not on the day. Auto-renewal is convenient and it is also where premiums quietly climb, so a fifteen minute re-quote each year is time well spent. Tell the insurer when your work changes: a new trade, first employee, a van upgrade, turnover doubling. Cover priced for last year’s business does not stretch to cover this year’s.
Employers’ liability certificates are worth keeping for the long term rather than binning at renewal, because a claim from an old employee can surface years later and you will need proof of who insured you at the time.
So What Small Business Insurance Do You Actually Need?
If you employ anyone, employers’ liability, because that one is not a choice. If you set foot on other people’s property or the public comes near your work, public liability at the limit your best customers demand, not the cheapest limit on the screen. If people pay you for judgement, professional indemnity. If your tools or your hands are the business, cover for losing either.
Everything past that is a bet on what a bad month would cost you against what the premium costs. Sensible small business insurance is not the longest list. It is the shortest list that would still leave you trading after the worst realistic thing happens.
