answers are reliant on budget and requirements.
I would assume you are wanting national but do you want wood or poly.
Poly I would say abelo - https://www.abelo.co.uk/shop/poly-hives-national/national-poly-hive-with-2-supers-frames-foundation/ I have Abelo poly hives and they are spot on. I am very happy with them.
wood starter kits - i cant comment as I have never bought a starter kit. Although I would suggest be aware some will be seconds and some will be first quality. Seconds quality tends to use British western red cedar with knots and firsts tend to be Canadian western red cedar and no knots. Canadian timber grows slower due to it being colder there and this means the wood is better quality (so I am told) when harvested. I tend to buy maisemores or thornes in the sales ( which were last month and the month before btw)
Hive tools, you cant beat simon the beekeeper, they are £2.99 and do the job, he also does cheap suits at £30 but you get a £30 quid suit. I have had them and they are ok, but dont last to long, depends on the amount of hives you have I suppose.
Good quality suits try Sherrif bee suits and they are about £140 ( I have one of these and I am very happy with it) although there are a lot of folk going for the 3D beesuits these days, like these sold here https://www.oldcastlefarmhives.com/ - my mate has one of these (this exact one) and he is very happy with it.
If you wanna buy bees, If you want to travel to Wakefield, West Yorkshire, I will sell you a nuc overwinterd. PM me for details.
