Connecting flights at Terminal 3 can be a time-consuming process, with a current traveller rating of 4/10 reflecting its challenges. After deplaning, be prepared to follow the purple signs to reach the shuttle bus that connects you to your next terminal, as transfer times can be lengthy. Security checks are stringent, particularly regarding liquids, which may slow down the process, so allow ample time for these procedures. Planning for a longer layover may be beneficial to ensure a smoother transition between flights.

Crowdsourced tips for Connecting Flights at London Heathrow Airport - Terminal 3
It takes a while to transfer between the terminals, you need to follow the purple signs and then wait for a shuttle bus. My flight was delayed and deplaning took longer than usual so I was glad that I booked a longer layover. Security is very strict on liquids and all the secondary checks were slowing down the line. A bit chaotic and I was grateful I made my connection.
