Now it's not surprising that the offline checks fail given the name imbalance, but at the airport if they check this - which I doubt - then they'll still clear you. Just calmly present documentation as required and when asked at check-in. Incidentally my NHS name doesn't align with my passport either, it isn't unusual, never mind all the maiden versus married name mis-matches. The sky won't fall in.
Thanks for the response corporate wage slave. I hope you're right. It's annoying because I can't get through to BA customer service (not surprisingly) but reason why I'm worried is that you have to upload the docs onto your booking, otherwise you can't even check in. I asked BA on their social media page and someone there told me that I would need to speak to my GP and ensure the names on my document matches the names on my ticket apparently...
I will go to my GP then first thing in the morning and hope they can do the name change.
