Firstly, packages will be difficult to get again next year unless we see a change in the ridicules legislation that we have had to work with this year.
The facts are that packages come with less problems in terms of disease and are inspected by SBI, however they are seldom produced in the UK.
Over wintered nucs would be a good option, local bees or at least UK reared, the drawback is disease and temperament. Generally they are only inspected by the producer.
Best option in my opinion is to produce your own nuc and rear queens, it’s no difficult.
