Hi Furryears. Excellent time the year to start beekeeping. Find your local association via the BBKA website and make contact, attend winter meetings to meet other local beek's. In the spring visit some hives just to make sure you are happy with bees - it's not for everyone. You will most likely be able to borrow a suit. Cost to date nothing
Purchase a good quality suit, our club has arranged discount with one of the suppliers, don't invest in a poor quality bargain - you'll waste time messing with zips trying to make it bee tight and then still find bees troubling you!
Purchase your first colony from the club or a local member, there's always people giving up or down sizing, go with the flow and buy the style of hive others are using then when you need something you will be able to borrow. You may be able to get involved with swarm collection to source your first bees then you would only need the hive.
As for the extractor, as already mentioned, clubs usually have these for members to borrow so investment in the early years need not be excessive.
So costs.....£60/£80 for a suit, 2nd hand hive with bees....£100-£250+ depending on state of hive, membership of local club £30-£50....other bits & pieces, smoker etc etc £50ish.
Thornes is a good website for info on equipment, don't know where you are but they are having an annual sale in a couple of weeks, Then there's the BeeTradeX event and BBKA Spring convention early next year, both good events.
Good luck with your next venture, look us up if your in the Suffolk arae
