If you have not had bees before I would thoroughly recommend doing a beekeeping course and joining your local beekeepers assoc.
If you get a colony now you do run the risk of the colony not surviving the winter. You would need to be very confident that they had enough stores, the queen was not too old and they had been treated for varroa (or you would need to treat them) to give them the best chance. The plus point would be that you would then have a colony that should, theoretically, be ready to get going for next year and be in a position to give you a surplus of honey.
Alternatively reserve yourself a colony first thing next spring from a fellow experienced beekeeper - some will do this and make sure that the colony is viable for you next spring. As you can imagine the cost of such a colony would be more expensive than one now (if there are any available in the first place) because of the reduced risk you are taking.
I got my first bees this year - in June. The weather has been so sh1te that quite a few of the beekeepers in the assoc are not able to take off any honey - me included
I am hoping that I will get my colony through the winter so that they have a chance of getting going in the spring next year.
