where do you want to start
size of box, lang is larger but national is more common in the uk but no one uses them abroad realy
how about cell size of a 12 by 14 say to a lang and we are equal, the list is endless,
but if i can be very rude try this answer.
most UK nucs are served up on a national frame it being the most common in the uk, so if your supplier for next year and i would by now have started to either pre pay or at least order your nuc to beat the que, if he can supply in either of the frames or you have the ability to order without frames ie easy bee where they come loose you can have any frame and hive you want.
as ever with most people if you remove the uk bit in your description and realy say where your from or where you are planning on keeping the bees uk or europe these answers will also help if your in europe i would defffinately go poly hive not timber and i would also go either lang or dadant not national
there that should confuse you
Why is top bee space superior ?A new Langstroth hive will cost a quarter of what a National hive will. Langstroth hives are also top bee space far superior to bottom beespace nationals. Once you have worked a Langstroth hive there is no way you would go back to a national. Most commercial beekeepers in the UK would be using Langstroths.
It depends on material. Here wooden insulated box is 2 times expencive that of plastic (2-wall ply).From what I have seen in the Catalogues, Langstroth hives cost more. Maybe they are just expensive in the UK.
