Keeping bees for profit must be an entirely different proposition from those like me who keep them more as a pet/hobby.
A few thoughts from the world of accountancy for you:
1) Are you sure you make a profit? Does the cost of the equipment, drugs, time, etc work out to be less than your sales?
2) Are you dealing with financing costs properly?
3) Are you dealing with taxes properly (VAT, income tax, NI, capital allowances etc)
4) Have you done a "profit profile"? Do you know, for example, what makes you the most money. Is it the honey? Is it the wax? Is it pollen? is it Mead (watch duties again there), is it nucs, is it polish etc? The most profitable is where to try and concentrate breeding/effort.
5) Somene mentioned adding value - selling candles rather than wax would be a good example of that. Can you get more for a candle than the wax+time+equipment for making candles?
6) Would you wish to run "open days" or courses for people to show them hives, like breweries do tours?
7) Can you differentiate in some way - say do graded honey packs of three jars as tasters?
8) Publicity - any way you can try convincing local chefs to use YOUR honey, and tell people. I see you are Derbyshire - The Bay Tree in Melbourne is a brilliant place, the chef may help you.
9) Branding, pricing and thinking. New Zealand honey is very similar ours, but they've managed to come up with this health index thing, and charge a fortune for high indexes. Think about something similar - but watch unproven health benefits. Likewise look at Fortnum and Mason. Same stuff, twice the price.
10) Prized - if you win honey show prizes, get the prize on the label (XXX Apiary won the Gold award at XXX in 20XX) etc
