Key takeaways

  • Turn on two-step verification, starting with your email. It is the single best protection if one of your passwords ever leaks.
  • Use a password manager and three random words, and never reuse the same password across accounts.
  • Keep everything updated and move off Windows 10 (free support ended on 14 October 2025) to Windows 11 or Extended Security Updates.
  • Back up with the 3-2-1 rule, keeping one copy offline so ransomware cannot reach it.
  • You do not need to pay for antivirus. Microsoft Defender, built into Windows, is now genuinely excellent. Keep it switched on and updated.

When I first wrote this article back in early 2021, half of Manchester had been turned into a makeshift office almost overnight, kids were learning at the kitchen table, and working from home still felt temporary. Five years on, it is just work. Hybrid and home working are a permanent fixture, and that means securing your home office is no longer a lockdown stopgap. It is something every home worker and small business owner should get right and keep right.

So I have rewritten this guide from scratch for 2026. I have shifted the focus to where it matters most, towards protecting your data, your accounts and your devices, while keeping a tightened section on the physical hazards that genuinely still catch families out. I have also corrected some advice from the original that is now out of date, including the old line about free antivirus being poor, because the world has moved on. This is the honest, practical version I would give a friend setting up to work from their spare room in Sale or a back bedroom in Withington.

Start here: the four things that matter most

If you do nothing else from this article, do these four. They are the highest-impact, lowest-effort wins, and they are the same four the National Cyber Security Centre (NCSC) keeps coming back to for good reason. Everything after this is detail and refinement, but these four are the foundation:

  1. Turn on two-step verification, starting with your email.
  2. Use strong, unique passwords (three random words) with a password manager.
  3. Keep your devices and software updated, and get off Windows 10 if you have not already.
  4. Back up your important data using the 3-2-1 rule.

Let me take each one properly, because the how matters as much as the what.

Turn on two-step verification

If a criminal gets hold of one of your passwords, through a data breach, a phishing email or a lucky guess, two-step verification (2SV) is what stops them actually getting in. It asks for a second proof of identity, usually a code from an app or a tap on your phone, on top of your password. The NCSC describes turning it on as one of the most effective ways to protect your accounts, and I completely agree.

Two-step verification means a stolen password alone is not enough to get into your account. Turn it on for email first.

Start with your email, and here is why: your email is the master key to your whole digital life. If someone controls your email, they can reset the password on almost everything else, from your banking to your cloud storage to your work systems. Lock that down first, then move on to banking, social media and anything holding client or company data. You will see it called 2SV, 2FA or MFA. They are all the same idea, and any of them is enormously better than none.

The direction of travel is towards passkeys, which replace passwords entirely with a secure key on your device, unlocked by your fingerprint, face or PIN. The NCSC now recommends passkeys as your first choice of login where a service offers them, because there is no password for anyone to steal or phish. Where passkeys are not available yet, a strong password plus 2SV is your standard.

Strong passwords: three random words and a password manager

In the original 2021 version of this post I leaned on the old "make it complex" advice: capital letters, numbers, a special character. The thinking has moved on. When you force people to invent complicated passwords, they cope in predictable ways, and criminals know every one of those tricks. As the NCSC puts it, complexity requirements counter-intuitively end up producing more predictable passwords.

The better approach is three random words. Put three unrelated words together, something like coffee rocket marble, and you get a password that is long, genuinely hard to crack, and far easier to remember than a tangle of symbols. Just do not use words anyone could guess about you, and do not lean on predictable swaps like an "o" for a "0".

The real game-changer is a password manager. Nobody can remember a strong, unique password for every account, and reusing one password everywhere is exactly how a single breached website hands criminals the keys to your email and bank too. A password manager creates and stores a different strong password for every account, so you only have to remember one master password (make that one three random words). The managers built into your browser or phone are perfectly safe on your own devices. Turn on 2SV for the password manager itself, and you have closed the loop.

Keep everything updated, and get off Windows 10

Updates are not just new features. A huge proportion of them are security patches, fixes for holes that criminals are actively trying to exploit. The NCSC's advice is simple: keep your operating system, browsers, apps and security software up to date, and turn on automatic updates wherever you can.

One update matters more than any other right now. Windows 10 reached the end of its support life on 14 October 2025, so Microsoft no longer provides free security updates for it, and every new vulnerability found since then stays unpatched on a standard Windows 10 machine. If you are still on Windows 10, here are your options:

Your situationWhat to do
Your PC is eligible for Windows 11Upgrade to Windows 11 (free for qualifying PCs). The right long-term move.
Not eligible or not ready yetEnrol in Extended Security Updates (ESU), free for home users, running until 12 October 2027. Treat it as breathing space, not a destination.
Machine too old for Windows 11Replace it. We can advise on a sensible, cost-effective upgrade.

If you are not sure which camp your laptop falls into, that is exactly the kind of thing we check for people every week. A quick look will tell you whether you can upgrade or whether ESU is the sensible stopgap.

Back up your data: the 3-2-1 rule

Ransomware, where criminals encrypt your files and demand payment, is one of the nastiest things I see in the workshop, and hardware simply fails sometimes too. Either way, a good backup is the difference between a bad afternoon and a genuine disaster, especially when it is client work or company data on the line.

The rule worth memorising is 3-2-1: keep at least three copies of your important data, on two different types of device, with one copy kept offline or off-site. So that might be the working copy on your laptop, a backup on an external drive, and a third copy in cloud storage. The crucial part is that offline copy. The NCSC specifically stresses keeping at least one backup disconnected, because ransomware can only encrypt what it can reach. And do not forget to test that you can actually restore: a backup you have never checked is just a hope.

Antivirus in 2026: free really is fine now

This is the part of the original article I most wanted to correct. In 2021 I told you free antivirus was usually well behind the rest of the industry. That advice is now out of date, and I would be doing you a disservice to leave it standing.

The free antivirus built into Windows, Microsoft Defender, has become genuinely excellent. It is included in Windows 10 and 11, switched on by default, and you do not have to pay extra for it. More to the point, it performs. The independent lab AV-TEST scored Microsoft Defender top marks for protection in round after round through to 2026, alongside the big paid names, and the NCSC's own guidance says the antivirus built into Windows, macOS and Android will meet the needs of many organisations.

So for most home users, the honest advice in 2026 is to keep Microsoft Defender switched on and updated, and you are well covered. Two caveats: never run two antivirus products at once, because the security benefit is minimal and they can conflict and make your machine unstable; and paid suites mainly add bundled extras like a VPN or identity monitoring, which is a value judgement about features, not a safety necessity.

Secure your home Wi-Fi and router

Your router is the front door to your entire home network, and for a home worker that network now carries work email, client files and company logins. It is worth five minutes to harden it:

  • Change the router's admin password (the one for its settings, not the Wi-Fi password). Use three random words. New devices sold since 2024 can no longer ship with a guessable universal default, but older routers should be changed.
  • Use WPA2 or WPA3 encryption for the Wi-Fi itself. Any router from the last several years supports this; check it is enabled rather than an older, broken standard.
  • Keep the router's firmware updated, turning on automatic updates if it offers them.
  • Put smart gadgets on a guest network. Smart speakers, video doorbells and robot vacuums are notorious weak points. The NCSC's smart-device guidance is worth a read; keep your work laptop on the main network and the gadgets on a separate guest one.

Your router is the front door to a network that now carries work data. Five minutes of hardening goes a long way.

On VPNs, let me be straight. If your employer provides a VPN, use it whenever you access work systems and keep its software updated; follow the NCSC's corporate VPN guidance and your company's instructions. What I would push back on is the marketing for consumer "privacy" VPNs. For most people working on their own secured Wi-Fi, a consumer VPN is not the essential shield the adverts suggest, because modern websites already encrypt your connection. Where it genuinely earns its place is on Wi-Fi you do not control, like a cafe, hotel or airport.

Spotting and reporting phishing

Working from home, you do not have a colleague to lean over and ask "does this look dodgy to you?", so it pays to know the signs yourself. Phishing is still the most common way criminals get a foothold: an email or text that pressures you to click a link, log in, pay an invoice or hand over a code, usually by manufacturing urgency. A few patterns to watch for in 2026:

  • Quishing: QR codes in emails or on posters that lead to fake login pages.
  • Vishing: phone calls from someone pretending to be your IT department or bank, talking you into installing software or reading out a code.
  • Anything that rushes you, especially around money or login details. Slow down and verify through a channel you trust.

If something looks off, do not click, and report it. Forward suspicious emails to report@phishing.gov.uk, the NCSC's Suspicious Email Reporting Service, and forward scam texts to 7726 (it spells "SPAM" on the keypad, and it is free on most UK networks). Tens of millions of reports have led to hundreds of thousands of malicious websites being taken down.

Locking down the device itself

Two quick wins protect your data if a device is lost, stolen, or just left unattended with the kids about:

  • Turn on device encryption. If your laptop is lost or stolen, encryption stops a thief simply pulling the files off the drive. Windows 11 includes Device Encryption (and BitLocker on Pro), and on many modern machines it switches on automatically when you sign in with a Microsoft account. Worth checking it is on, especially if you handle client data.
  • Lock your screen when you step away. Pressing the Windows key and L whenever you leave the desk stops a child, housemate or visitor seeing, or accidentally sending, something they should not. In a home full of curious hands, this matters more than people think.

And a sensible principle to finish: keep work and personal separate where you can. Do not do company work in your personal email, do not reuse personal passwords on work accounts, and follow whatever security policy your employer has set. Mixing the two is how a personal breach becomes a work breach.

Handling client and company data at home

If you are a sole trader, an accountant doing the books from the dining room, a tradesperson handling customer details, or anyone working from home with other people's personal information, then UK data protection law (UK GDPR) applies to you just as it would in an office. The good news, as the Information Commissioner's Office (ICO) points out, is that much of it is common sense you are probably already doing. A few practical points:

  • Apply the same standards at home as at the office. The ICO has a dedicated working-from-home security checklist worth following.
  • Protect and securely dispose of paperwork. Confidential letters and printouts should not sit in the recycling where they can be read or stolen; criminals fish out letterhead and documents for invoice fraud. A cheap cross-cut shredder is a sound investment, and the ICO covers shredding sensitive documents among its common-topics advice.
  • Keep work documents out of family reach, both to protect confidentiality and to stop your six-year-old turning a client contract into a colouring page.

Home office safety: button batteries and a quick sweep

The original version of this post spent a lot of time on physical child-safety, because it was written when kids were home all day. I have trimmed it right down, but there is one hazard I will not drop, because it is genuinely serious and hiding in plain sight in almost every home office.

Round button and coin cell batteries on a desk beside a remote control
Button and coin batteries are in more of your desk kit than you think, and they are a serious danger to young children.

Those little round, shiny batteries are in remote controls, key fobs, calculators, kitchen and luggage scales, thermometers, fitness trackers and musical greetings cards. If a child swallows one, it can react with saliva and burn through the throat or stomach within hours. The Royal Society for the Prevention of Accidents (RoSPA) is aware of UK deaths and life-changing injuries caused this way, and even a "flat" battery still holds enough charge to do harm. So check that battery compartments need a deliberate action or a screwdriver to open, store spare and used batteries well out of reach, and dispose of dead ones promptly. If you ever suspect a child has swallowed one, go straight to A&E or call 999 and do not wait for symptoms; the Child Accident Prevention Trust has clear guidance.

While you are at it, a five-minute sweep of the rest: route and tidy trailing cables so nobody trips and no child can pull a monitor down by its lead; anchor top-heavy shelving to the wall; keep drawing pins, staples and USB sticks in closed drawers; and give plugs and leads a quick check for damage without daisy-chaining overloaded extension leads. The HSE has free guidance on setting up a home workstation safely, which also helps your posture over the long term.
