Running a Business From Home in the UK: What Your Home Insurance Won’t Cover (and What Can Void It)

Priya ran her whole jewellery business from the spare bedroom. Stock in the wardrobe, laptop on the desk, customers at the door twice a week to collect orders. She assumed her home insurance had it covered, because the business lived inside her house.

It did not. And the part that surprises most people is not that her stock was uninsured. It is that by never mentioning the business, she had put the entire household policy at risk — the buildings, the contents, everything.

Here is how home insurance and business use actually interact in the UK, what you have to tell your insurer, and the three other permissions that matter more than the insurance does.

The risk is not a gap in cover. It is a void policy.

Most articles on this frame the problem as underinsurance: your business kit falls outside the policy, so buy an add-on. That is true, and it is the smaller half of the story.

The bigger half is disclosure. Admiral puts it about as plainly as an insurer ever does: not letting an insurer know may invalidate your policy. Not “the business items won’t be covered” — invalidate. If your insurer decides you materially changed the risk without telling them, they can treat the whole policy as if it were never properly in force.

Think about what that actually means. A kitchen fire. A burglary while you are away. A burst pipe through the ceiling. None of them have anything to do with the jewellery in the wardrobe, and all of them could be declined because the business was never declared.

That is the reason to make the phone call, and it costs nothing to make.

So what does home insurance actually cover?

The line UK insurers draw is between clerical work and everything else.

If you sit at a computer, answer emails and take phone calls, you are almost certainly fine already. Admiral covers clerical work as standard — “using a computer or taking phone calls” — and working from home in that sense is usually covered by a normal home policy without any change.

Step beyond that and the position reverses fast:

• Business equipment is frequently excluded outright. Hiscox notes that most household policies do not cover damage to items used for business purposes. Admiral goes further and does not offer business equipment cover at home at all.
• Business visitors are excluded. If a customer is hurt collecting an order, a home policy will not respond. Neither will it cover employees, or injury caused by products you supply.
• Employer-provided kit is not yours to insure. A work laptop belonging to your employer sits under their business policy, not your contents.
• Kit that leaves the house needs its own cover. A laptop used in cafés and at client sites needs all-risks or personal possessions cover.

Anything that is not clerical — a workshop in the shed, yoga taught in the garden, stock in the spare room, clients through the front door — has to be declared.

The ladder: which tier are you on?

Insurers describe their products. What nobody publishes is the ladder, and the answer is completely different at each rung.

Tier 1 — employed, clerical only, using your own equipment

You are almost certainly covered already, and you probably need nothing extra. Tell your insurer anyway. It is a two-minute call, it usually changes nothing, and it removes any argument later.

Tier 2 — self-employed, no visitors, no stock

Declare the business. Then add cover for your own equipment, because your home policy will not carry it, and professional indemnity if clients pay you for advice, design or analysis. A graphic designer working this way pays around £11.52 a month, or £95.20 a year.

Tier 3 — customers visit, stock is held, staff work for you, or you make and sell products

Declare, and now you need real business cover: public liability for the people who come to the door, contents and stock cover for what you hold, product liability if you make or sell things. A home-based masseuse with public liability pays about £7.00 a month, or £49.99 a year.

And if anyone works for you at all — including part-timers, freelancers and volunteers — employers’ liability is a legal requirement, minimum £5 million. That one is not a judgement call.

Priya was firmly on tier three and insured for tier one. That was the whole problem.

What it costs, and why the American numbers mislead

Home-business cover in the UK is cheap. The two real quotes above — £49.99 and £95.20 a year — are typical for a one-person operation, and they buy far more than a home insurance add-on would.

This is worth saying because a lot of advice circulating online is American, where the standard recommendation is a “business owner’s policy” or BOP at around $57 a month. That is over £500 a year, and the BOP does not exist as a product in the UK. What UK insurers sell instead is a combined policy, where you assemble public liability, business contents and professional indemnity into one package — usually for a fraction of that.

Price is almost never the reason UK home businesses go uninsured. Not knowing they had to declare is.

Insurance is the fourth permission, not the first

Here is the part the insurance pages skip entirely, because they are not selling it. Before the cover question, government guidance says you may need permission from several other people.

• Your mortgage provider or landlord. This is the sharpest one. Running a business from a rented home needs your landlord’s written permission and the tenancy agreement updated to match. On a mortgage, breaching the terms of the loan can in principle make it repayable immediately. That is a far larger problem than an uninsured laptop.
• Planning permission, but only if the character of the property changes — a marked rise in traffic or callers, activities unusual in a residential street, or disturbance to neighbours. Most home businesses cause no change of use at all and need nothing. A steady stream of customers to the door is where that changes.
• Your local council, if you will have lots of customers or deliveries, want to advertise outside the property, or need a licence for what you do.
• Business rates. You may have to pay them on the part of the property used for the business — typically where a room is used solely and specifically for business, or customers come to the premises.

Sorting your insurance while quietly breaching your mortgage conditions is solving the small problem and leaving the large one running.

What to do this week

In order:

1. Check your mortgage or tenancy terms for anything about business use, and get written permission if you need it.
2. Ring your home insurer and declare the business. Ask them specifically to note it, and ask whether business equipment and business visitors are covered — assume the answer is no unless they say otherwise.
3. Work out your tier. Clerical only, or self-employed without visitors, or visitors and stock and staff.
4. Buy the business cover that matches the tier, not the widest policy on offer. Public liability if people come to you, professional indemnity if you sell judgement, contents and stock for what you hold, employers’ liability the moment anyone works for you.
5. Check whether business rates apply if you have given a room over entirely to the business or customers visit.

Priya moved to a proper combined policy after that slip on the front step. The next time a customer had a mishap at collection, it was a phone call and a claim rather than a personal financial hole — and, just as importantly, her home policy was still intact.

Home-based does not mean low-stakes, and it definitely does not mean your home insurance has you covered.

If you are weighing the two main covers against each other, we have gone through public liability versus professional indemnity in detail, and if budget is the constraint, here is what the cheapest cover really costs a sole trader.

Frequently asked questions

Does home insurance cover working from home in the UK?

Usually yes, if the work is purely clerical — a computer, a phone, your own equipment. Anything beyond that, such as stock, business visitors, a workshop or specialist equipment, falls outside a standard home policy and has to be declared.

What happens if I do not tell my home insurer about my business?

The insurer may treat the policy as invalid. Admiral states directly that not telling them may invalidate your cover, which can affect claims that have nothing to do with the business — a fire, a burglary or an escape of water.

Does my home insurance cover my business equipment?

Generally not. Most household policies exclude damage to items used for business purposes, and some insurers do not offer business equipment cover at home at all. Equipment provided by an employer sits under the employer’s policy instead.

Do I need public liability insurance if customers visit my home?

It is not a legal requirement, but your home policy will not cover injury to a business visitor, so in practice yes. Home-based public liability starts at around £7 a month.

Do I need planning permission to run a business from home?

Only if the character of the property changes — a marked increase in traffic or callers, activities unusual for a residential area, or disturbance to neighbours. Many home businesses need no permission at all, but you may still need your landlord’s or mortgage provider’s consent.

Will I have to pay business rates?

Possibly, on the part of the property used for the business. It typically applies where a room is used solely for business or where customers come to the premises. Check with your local council.

How much does home business insurance cost in the UK?

Real quotes in 2026 run from about £49.99 a year for a home-based masseuse with public liability to £95.20 a year for a graphic designer with professional indemnity. American advice quoting around $57 a month refers to a “business owner’s policy”, a product that does not exist in the UK.

Figures reflect UK market data published in 2026 and are general information, not financial or legal advice. Cover, planning rules and business rates vary by insurer and local authority — check with yours before relying on any of this.
