Is an ETA mandatory for passengers transiting through the same terminal at Heathrow?

I just did this last week and it was better than it used to be, but I'd still make sure you have plenty of time (especially traveling with kids). I didn't have to have liquids in a bag.

I'm not adding anything to the discussion, but f**k Heathrow. Doesn't seem to matter how long my layover is, somehow I'm always stressing out in line, running to the gate trying to make my connecting flight.

(By 'always' I mean twice. Still, they were both awful experiences.)

We didn’t have a connection but we arrived in T3 on Virgin last summer and had zero issues whatsoever. Breezed through immigration as a US citizen.

They have been testing it in T2 (United and others) since last May at least, but it wasn't in T5 (BA) in July. It is supposed to be in the whole airport now. It was in T2 last month for sure.

+10. Allow extra time for unplanned delays.

As of early 2026, Heathrow Terminal 3 has fully installed advanced CT security scanners. Passengers can keep liquids (up to 2 liters) and large electronics (laptops/tablets) inside their bags. The new technology removes the need for plastic bags, significantly reducing security wait times and streamlining the screening process

Anyone have experience traveling through terminal 3 at Heathrow airport. We have a connecting flight that arrives and leaves from Terminal 3.

Do we have to go through security? If so, how backed up is security usually?

Is it easy to get from one gate to the next?
