Same thing at Malaga (AGP) the flights going back to the UK need the EES protocols and will, almost certainly, go from B or C after passport control, so make your way there before the actual gate is announced. There are cafes/toilets etc there too, so no issues.
Always a 0.1% risk that your flight might go from another area, but I've never known that to happen.
IBZ is different though - there are no separate terminals and passport could be done in two places, either before security or as you leave the gate still?
