LHR T5 transit times

[elanshin]

Travelling to UK via BA from HKG BA32 and looking to go up to GLA or EDI on a separate ticket but flights on the day were insanely priced (400+ pounds one way). So I spotted a 0800 LHR - NCL flight but I'm wondering if its reasonably doable transit.

BA32 usually lands into LHR around 6am. BA1326 on that day departs at 0800, both at T5. We will have OWE priorities but on separate tickets. Is this a possible connection on separate tickets or one where you cross every part of your body and hope everything goes through just right?

The alternative i think is that we go into town and take a train up.

Are you flying with hand luggage only? Otherwise you will have to collect your luggage, check in again, and then go through security again. Landing at 6:00am also doesn’t mean disembarking soon after as there could be a long taxi. You are an experienced flyer: will your nerves take the tension?
