That is not really correct.
The OP is arriving from Qatar (non-Schengen) and is transfering to a flight to Great Britain (also non-Schengen). Hence the OP
does not have to posses a Schengen visa according to immigrations rules when changing flights at a Schengen airport such as ARN, unless he is a citizen of Afghanistan, Bangladesh, DR Kongo, Etiophia, Eritrea, Ghana, Iraq, Iran, Nigeria, Pakistan, Somalia or Sri Lanka.
When transfering from a non-Schengen flight to a non-Schengen flight you do not have to pass thorugh passport control at ARN. The transfer bus airside between T5 and T2, at least some years ago when I tried it, was available on request even between non-Schengen areas at the different terminals. There were then specially assigned bus gates for such a transfer. You can e-mail the Airport information to check whether the air side bus is still running between non-Schengen areas at T5 and T2,
