Running a business from home offers real advantages: lower overheads, no commute and the flexibility to fit work around caring responsibilities. But those benefits come with a downside that is easy to overlook: you are personally responsible for keeping your business, your data and anyone who visits your premises safe.

Security is not just about deterring burglars. It covers health and safety, insurance, data protection and cyber security. According to the Cyber Security Breaches Survey 2025 from the Department for Science, Innovation and Technology, 43% of UK businesses experienced a cyber security breach or attack in the last 12 months. With hundreds of thousands of women running businesses from home across the UK, the financial and reputational cost of a preventable incident can be severe. A clear home business security plan lets you focus on growth rather than recovery.

The space around you: health, safety and risk assessments

In a conventional office, someone else usually manages health and safety compliance. When you work from home, that responsibility falls on you. The good news is that most risks are easy to manage once you identify them.

Start with a simple risk assessment. Under the Management of Health and Safety at Work Regulations 1999, every employer must assess workplace risks, and the self-employed are covered where their work poses a risk to others. Look at where you work, how you move around the space and what could cause harm. Keep expensive or fragile equipment away from doorways, windows and high-traffic areas where it could be knocked over or damaged by rain, draughts or direct sunlight. Make sure desks, shelves and storage units are strong enough for the load you place on them, and never stack heavy items above head height.

Fire safety deserves particular attention. Do not overload extension leads, keep cables and electrical equipment away from liquids, and make sure you have working smoke alarms on every floor. If you use a lot of electrical devices, consider having them inspected periodically by a qualified electrician. You should also know your escape route and keep it clear at all times.

If you employ anyone, even on a casual basis, you have legal duties under the Health and Safety at Work etc. Act 1974. That includes providing a safe workstation, suitable seating and adequate lighting. The Health and Safety Executive has free guidance for employers and the self-employed.

Display screen equipment regulations also matter if you or anyone you employ uses a computer for an hour or more at a time. You must assess workstation risks, provide breaks and, on request, pay for eye tests.

Physical security: locks, storage and surveillance

You do not need to run a large company to be a target. Home businesses often hold valuable equipment, stock and customer information, all of which can be attractive to thieves. You also have a legal duty under the UK General Data Protection Regulation and the Data Protection Act 2018 to keep personal data secure.

Begin with the basics. Fit sturdy locks on external doors and any rooms where you store business property or records. Use a lockable filing cabinet or safe for paper records, memory sticks and backup drives. If you no longer need documents that contain personal data, shred them rather than throwing them away.

Security cameras can act as a deterrent, but you must use them responsibly. If cameras capture public areas or anyone outside your household, you need to comply with data protection rules set by the Information Commissioner’s Office. That usually means telling people that recording is taking place, keeping footage secure and only keeping it for as long as necessary. The ICO CCTV guidance explains when domestic cameras fall under data protection law.

Good lighting around entrances, visible locks and an alarm system can also reduce the risk of break-ins. If you hold high-value stock at home, speak to your insurer before investing in additional security, as some policies require specific measures.

Insurance: the cover you cannot afford to skip

Insurance is rarely exciting, yet it is one of the most important protections a home business can have. The right cover means that a single incident does not force you to close.

If you employ anyone, employers’ liability insurance is a legal requirement in almost all cases. According to Health and Safety Executive guidance, you need cover of at least £5 million and you must display your certificate where employees can see it. Failing to have it can result in fines of up to £2,500 for every day you are uninsured.

Public liability insurance is not required by law, but it is essential if clients, customers or suppliers visit your home. It covers compensation claims if someone is injured or their property is damaged because of your business activities. Many clients and event organisers will ask to see proof of cover before they work with you.

Professional indemnity insurance is worth considering if you give advice, provide designs or offer professional services. It covers legal costs and compensation if a client claims your work caused them financial loss. You may also need business contents insurance, stock cover, product liability insurance or cyber insurance, depending on what you do.

Do not assume your standard home insurance will cover business equipment or liability. Many domestic policies exclude business use, so speak to a specialist broker and compare quotes to make sure you are fully covered.

Cyber security: practical steps to protect your data

Cybercrime is one of the biggest security risks facing UK small businesses today. The Cyber Security Breaches Survey 2025 found that 84% of businesses now say cyber security is a high priority for senior management, yet the median cost of a breach was £1,205. For a home business, that is money better spent elsewhere.

Backing up your data is the single most important step. Use a reputable cloud backup service or an encrypted external drive, and keep at least one copy off-site. Test your backups regularly to make sure you can actually restore your files.

Protect your accounts with strong, unique passwords and turn on two-factor authentication wherever it is offered. A password manager can help you generate and store complex passwords securely. The National Cyber Security Centre Small Business Guide provides free, practical guidance and recommends these tools as part of good security hygiene.

Be cautious of phishing emails, fake invoices and unexpected phone calls. The Cyber Security Breaches Survey 2025 found that phishing remains the most common type of breach, reported by 84% of businesses that identified an attack. Criminals often pose as banks, HMRC or trusted suppliers to trick you into handing over passwords or making payments. If something feels off, stop and verify the request through a known contact number or website.

Keep your software, operating systems and antivirus up to date, use a firewall, and make sure your home Wi-Fi router has a strong password and the latest firmware. If you handle sensitive personal data, encrypt devices and consider cyber insurance to cover the costs of a breach. The How to Secure Your Remote Work Environment in 2026 guide goes deeper on digital defences.

Make home business security part of your routine

Taking these steps may feel like a distraction from running your business, but they are far less costly than dealing with an accident, burglary, fire or data breach. Review your home business security plan at least once a year, or whenever your business changes significantly. That includes taking on employees, storing stock at home, buying expensive equipment or starting to handle more client data.

You can also reduce risk by keeping your business finances separate from personal accounts and claiming the right home working expenses through HMRC. Good records make it easier to prove losses, claim tax relief and recover quickly if something goes wrong.

Action steps to strengthen your security

• Walk through your workspace and write down three risks you can fix this week.
• Check that your smoke alarms work and your escape route is clear.
• Review your insurance against your actual business activities, not just your home contents policy.
• Turn on two-factor authentication on every business account that offers it.
• Run a backup test and check you can restore a file.
• If you use CCTV that films beyond your household, read the ICO guidance and put a notice in place.

By putting sensible home business security precautions in place now, you protect your customers, your reputation and your livelihood.
