Check whether the smart lock fits your existing door and cylinder - many UK flats use euro-profile cylinders and UPVC doors which some locks are specifically designed for. Some models clamp over your existing cylinder while others replace it entirely, so measure backset, cylinder type and door thickness before buying.
A Wi‑Fi bridge converts a Bluetooth or Zigbee/Z‑Wave smart lock into a remotely accessible device; confirm whether a bridge is included or sold separately. Look for stable connectivity (dual-band Wi‑Fi or reliable bridge) and clear instructions for pairing with your router and smart‑home hub.
Evaluate both the digital security (AES encryption, secure cloud practices) and the physical protection (anti-snap, anti-drill compatibility with your cylinder). Also check manufacturer security updates, whether the lock has third‑party testing or relevant standards, and how it handles forced entry and tamper alerts.
Decide which smart assistants and ecosystems matter to you - Google Assistant, Amazon Alexa and Apple HomeKit support varies by brand and sometimes requires a bridge. Consider features such as auto‑unlock, guest codes, activity logs, voice control and IFTTT/automation support.
Factor in battery life, the ease of changing batteries, and any subscription fees for cloud services or advanced features. Check whether installation is DIY‑friendly or requires a locksmith, and whether UK retailers offer returns, fitting services or local support.
