Working from home is now a permanent feature of UK business life, which makes digital hygiene when you work from home a business-critical habit, not a nice-to-have. For women running companies from kitchen tables, garden offices, or spare rooms, the risks are real. According to the UK government’s Cyber Security Breaches Survey 2024, half of all UK businesses identified at least one cyber security breach or attack in the previous 12 months. For micro and small businesses, the average cost of these incidents was £1,205. This guide gives you practical, current steps to protect your data, your clients, and your reputation.
Why digital hygiene matters when you work from home
Digital hygiene is the set of regular habits that keep your devices, accounts, and data secure. For a UK business owner, the stakes are higher than on a personal laptop. Under UK GDPR, the Information Commissioner’s Office (ICO) can fine organisations up to £17.5 million or 4% of total global annual turnover for the most serious data breaches. Good digital hygiene helps you meet your legal obligations and avoid the disruption that follows a successful attack.
Home-based businesses are a significant part of the UK economy. You can see the scale of women in business in the latest UK facts, and many of those enterprises are run from home. That makes domestic Wi-Fi networks, personal devices, and informal routines a common entry point for attackers.
Secure your home network
Your home router is the front door to your business. The National Cyber Security Centre (NCSC) advises treating it as core security equipment, not just a box supplied by your broadband provider.
- Change the default administrator password on your router.
- Use WPA3 encryption if your router supports it; otherwise use WPA2.
- Install firmware updates when your provider or manufacturer releases them.
- Keep the router in a secure location and disable remote management unless you specifically need it.
If you store client data or take payments from home, a separate guest network for family devices reduces the chance of an infected phone or tablet reaching your work files.
Use strong passwords and multi-factor authentication
Weak or reused passwords remain one of the easiest ways for attackers to access business accounts. The Cyber Security Breaches Survey 2024 found that only 33% of UK businesses have a formal cyber security policy, which means many home-based firms are relying on individual habits rather than systems.
A password manager lets you create long, unique passwords for every account without trying to remember them. Wherever it is offered, turn on multi-factor authentication (MFA). The NCSC reports that MFA prevents the vast majority of bulk phishing and automated attacks on accounts, making it one of the most effective controls available to small businesses.
Practise safe browsing and email habits
Phishing remains the most common attack type reported by UK businesses in the Cyber Security Breaches Survey 2024. Be cautious of unexpected emails, texts, or messages that ask for passwords, payment details, or urgent action. Check the sender’s address carefully, and hover over links to see the real URL before clicking.
When you visit websites for banking, HMRC, or client portals, look for the padlock symbol and https:// in the address bar. Keep your browser updated, and consider privacy-enhancing extensions such as ad-blockers or HTTPS enforcement tools from reputable developers. If you do fall victim to a scam, report it to Action Fraud.
Back up your data regularly
Ransomware and hardware failure can lock you out of client records, invoices, and project files. Backing up your data means you can restore operations quickly without paying a ransom. The Cyber Security Breaches Survey 2024 found that only 21% of UK businesses have carried out a cyber security risk assessment, so many home-based owners have not formally identified what data they cannot afford to lose.
Follow the 3-2-1 rule: keep three copies of important data, on two different types of storage, with one copy stored off-site or in the cloud. Check your backups monthly to confirm they work, and encrypt any backup that leaves your home. If you handle personal data, make sure your backup process complies with UK GDPR principles around security and retention.
Claim the right home working expenses
Good security costs money, but some of it can be offset through your tax return. If you are self-employed, you may be able to claim a proportion of broadband, phone, and equipment costs as business expenses. Our guide to home working expenses for the self-employed explains what you can claim through HMRC.
You should also consider whether cyber insurance is appropriate for your business. It is not a substitute for good digital hygiene, but it can cover legal fees, notification costs, and business interruption if a breach occurs.
Action steps for this week
- Run a password audit and update any reused or default passwords.
- Turn on multi-factor authentication for email, banking, and cloud storage.
- Check your router settings and install any pending firmware updates.
- Set up an automatic backup schedule and test a restore.
- Review whether your current setup needs cyber insurance.
Digital hygiene when you work from home is about building small, repeatable habits that protect the business you have worked hard to build. Start with your router, passwords, and backups this week, and you will have reduced the most common risks facing UK home-based businesses.
