Sorry, I don't live in the UK, so I wouldn't know. You'll have to deal with that company for any issues with the UK -- they've been fairly responsive for a company on the other side of the world.
It wouldn't hurt to pick up some additional hardware. the motors themselves come with some mounting screws, only two per motor can reach the threads, but no washers. the 1806 motors come with a pair of 2x.4x7mm bolts (tiny things) but I've been able to replace them with a 2x.4x8mm bolt and washer without issue. Don't get longer.
I'd also recommend picking up some M5 nylon locknuts -- they've got a nice flange version -- to replace the prop spinners. Also pick up one 5mm bolt to pre-stress the nylon insert -- these motors are too tiny to take the stress of bolting on a fresh locknut and torquing it down.
beyond that:
- 4 different colors of LED light strips -- it's tiny. Any orientation help you can get you'll appreciate.
- Basic building stock: Hookup wire, battery connectors, small zipties, male-male servo connectors for the RX, and velcro sitckyback and strap. Don't recall much else I used in building mine.
- More props -- 16 seems like a lot, it's not. Buy more. MANY more. I started out with 48 and after a couple of weeks I was ordering more just to make sure I didn't run out. Buy many, buy cheap. Eventually you're breakage rate will go down, then start considering getting nicer props, but you won't notice why better pilots call these cheap garbage until you can keep from breaking them anyways. Nicer props won't make you a better pilot at this point . . . just a poorer one.
- prop balancer -- you'll need it. Again, buy cheap -- the nicer balancing frames will have a hard time letting this small of a prop spin frictionlessly. get the cheap thumb balancer and use two drinking glasses on a level surface.
