How to Secure Smart-Home & Robot Devices UK (2026)
UK security guide — checked 7 October 2026: This is a research-led checklist based primarily on National Cyber Security Centre guidance and current UK smart-product security requirements. It is not a claim that every smart-home or robot product has been independently penetration-tested by The Tools and Tech.
Quick answer
Secure smart-home and robot devices by choosing products with a clear support period, setting a unique account password, enabling two-step verification, keeping device and companion-app software updated, disabling remote access you do not need, and removing old devices properly before selling or recycling them. Treat the manufacturer account and app as part of the product: a secure-looking camera, robot vacuum or hub can still expose data if its cloud account is weak.
What the UK rules already require
UK Product Security and Telecommunications Infrastructure rules set baseline requirements for many consumer connectable products sold in the UK. Manufacturers must not rely on easily guessable universal passwords, must publish a route for reporting security issues, and must make the minimum security-update period available to buyers. That support period is especially important for products expected to stay in a home for years.
The rules are a baseline, not a guarantee that every device is equally secure. Buyers should still look at the manufacturer’s update history, account-security options and privacy controls.
1. Check the support period before buying
NCSC guidance recommends avoiding devices that are already unsupported or close to the end of support. For smart cameras, robot vacuums, hubs, locks, speakers and similar products, security support should be treated like a practical “use by” date. A device may continue to function after updates stop, but known vulnerabilities are less likely to be fixed.
Before buying, look for a published minimum update period and record it somewhere you can find later. If two products are otherwise similar, the clearer and longer support commitment is a meaningful buying advantage.
2. Protect the manufacturer account
Many smart devices are controlled through a cloud account rather than only inside your home network. Use a strong, unique password that is not reused on email, shopping or social accounts. If the app or service offers two-step verification or multi-factor authentication, enable it.
This matters particularly for products that expose cameras, microphones, locks, location history, floor maps or remote controls. If an attacker gets the cloud account, changing the Wi-Fi password alone may not solve the problem.
3. Remove default credentials and review setup options
Newer UK-compliant products should not depend on a shared universal default password, but older or imported hardware may behave differently. If a device asks you to create a password during setup, make it unique. If it arrives with a default credential, change it immediately.
Also review privacy and sharing options instead of accepting every default. Check who can view camera feeds, whether household members have separate accounts, what data is stored in the cloud and whether voice, video, maps or activity history can be deleted.
4. Turn on automatic updates where available
Security fixes often arrive through firmware or the companion app. NCSC guidance recommends enabling automatic updates when the option exists and installing manual updates promptly when prompted.
Do not forget the phone app. A current robot or camera firmware version does not help if the controlling app is years out of date or installed on an unsupported phone.
5. Disable remote access you do not use
If you never need to control a device away from home, switch off remote-access features where the manufacturer provides that option. This reduces the number of paths into the device or account. If remote access is genuinely useful, keep it enabled but combine it with a unique password, MFA and current software.
6. Keep the home network maintained
Your router is part of the security boundary. Keep its firmware updated, use a strong Wi-Fi password and replace networking hardware that is no longer supported. If your router offers a separate guest or IoT network, using it for lower-trust smart devices can reduce how directly they interact with personal computers and storage devices. Network separation is useful defence in depth, not a substitute for securing the device account itself.
For a broader network plan, see our Wi-Fi security guidance and mesh/network buying guide; the same principles of updates, strong authentication and controlled access apply at home.
7. Pay extra attention to cameras, locks and robots with sensors
Different smart devices expose different kinds of information. Security cameras may contain live video and audio. Smart locks affect physical access. Robot vacuums and home robots may collect room maps, obstacle images, microphone data or cloud telemetry depending on the model.
Before buying a sensor-rich product, check what data is collected, whether cloud storage is optional, how long information is retained, whether household members can be separated by account, and what happens if the manufacturer ends the service.
8. Know what to do if you suspect compromise
- Change the manufacturer-account password from a trusted device.
- Enable or reset MFA.
- Review logged-in devices or sessions if the service provides that information.
- Update the smart device and companion app.
- Remove unknown shared users or integrations.
- If necessary, factory-reset the device using the manufacturer’s official instructions and set it up again.
If the manufacturer has published a vulnerability or incident notice, follow the vendor’s remediation instructions rather than relying on generic reset advice alone.
9. Factory-reset before selling or giving a device away
NCSC guidance recommends factory-resetting smart devices before resale or transfer. Also remove the device from your cloud account and check whether stored recordings, maps or histories need separate deletion. A physical reset button does not always remove server-side data tied to an account.
Smart-home security buying checklist
- Published minimum security-update period
- No shared/easily guessable default password
- Two-step verification for the associated account
- Automatic firmware updates or a clear manual update process
- Published security/vulnerability contact
- Clear privacy and data-retention controls
- Ability to remove shared users and revoke sessions
- Factory-reset and account-removal instructions
- Reasonable operation if the cloud service is unavailable, where that matters to you
How we researched this guide
We used the NCSC’s consumer smart-device guidance and UK government material on the Product Security and Telecommunications Infrastructure regime. Those sources emphasise support periods, unique credentials, two-step verification, updates, remote-access choices and secure disposal. We have not treated legal compliance as proof that a product is vulnerability-free.

Frequently asked questions
Does UK law mean every smart device is safe?
No. The rules establish baseline product-security requirements. They do not remove the need for updates, good account security, privacy checks and sensible purchasing decisions.
Should I put smart devices on a separate Wi-Fi network?
If your router supports a well-designed guest or IoT network, separation can be useful defence in depth. Make sure required local features still work and do not treat network separation as a replacement for updates and MFA.
What should I do with an unsupported smart device?
Consider replacing it if it remains internet-connected or handles sensitive functions such as cameras, locks or household data. If you keep it, reduce unnecessary remote exposure and understand that newly discovered vulnerabilities may not receive fixes.
Final verdict
The safest smart home is not necessarily the one with the fewest devices; it is the one where support dates, accounts, updates and data flows are understood. Buy from manufacturers that state how long they support products, enable MFA, keep software current, disable features you do not need and remove devices cleanly when their supported life ends.
