Watch out for fake networks
The official network begins with an underscore: _Heathrow Wi-Fi. Treat look-alike names (for example a network without the underscore, or one promising "unlimited free" access from an unknown provider) with caution. On any public Wi-Fi, avoid logging into banking or entering card details unless the site is secured (https), and consider a VPN for sensitive tasks.
Best for whom
- Short layovers: connect once and message ahead or check your gate — no time cap to watch.
- Remote workers on a long transit: usable for email and browsing; for video calls or large uploads, a mobile data plan or eSIM may be more reliable at peak times.
- Families: the Friendly Wi-Fi certification means content filtering is in place.
