I have heard that BA is pretty good. It's been a long time since I shipped Zack from the UK. I think you need a strong crate, that is not a wire crate. I know Zack had one built for him. It was solid wood with vents in the side and a very solid grid in the front. I believe you have to tape food to the top of the crate, but the shipper would tell you all that. His bedding should be something that he can't get tied up in. Shredded paper is good.
Glad you managed to find an apartment. Yes, finding accommodation that is reasonable in London is extremely difficult, but it sounds like you have found a great location with Hampstead Heath close by. Once you get out of London you will find lots of wonderful trails to walk.
By the way, the Beans who breed Rekaylahn Ridgebacks, (Sarah, breeders of Scotty's Sammy) now live in London. Not sure where but they should be in the Yearbook when it arrives.
