What to look for if you’re buying a smart lock in the UK
More people are fitting keyless devices to their front door – but are they worth it and do they affect your insurance? As the nights draw in, thoughts turn to home security.

UK homeowners considering a smart lock should check that the device is compatible with their door and confirm their insurer’s requirements before installation.
Smart locks can replace or work alongside traditional keys, allowing entry through methods such as a phone app, keypad, fingerprint, fob or voice assistant. Some models are designed to fit over an existing lock, while others replace the cylinder or the complete locking mechanism.
That distinction matters for insurance. A new device may not automatically meet the security standard required by a home insurance policy, particularly if it replaces an existing lock. Policy conditions vary, so homeowners should check the wording and contact their insurer before buying or fitting one.
Compatibility also depends on the type of door and lock already installed. British doors can use different cylinders, multipoint systems and mortice locks, and a smart lock made for one arrangement may not fit another. Buyers should check measurements and the manufacturer’s compatibility list rather than relying on a general claim that a product suits most UK doors.
The way a lock operates during a power, battery, phone or internet failure should also be considered. Some models retain a mechanical key, while others offer keypad or other local entry options. Buyers should establish how the door can be opened if the battery is flat or the connected service is unavailable.
Connected locks can also require a separate hub or compatible smart-home system for remote access. Features may differ depending on whether the lock uses Bluetooth, Wi-Fi, Zigbee, Thread or Matter, so the required equipment should be confirmed before purchase.
Homeowners should keep details of the lock, installation and any relevant security certification with their insurance documents. Where the insurer’s requirements are unclear, confirmation should be obtained before the existing lock is removed.
