Hhhmm, as one of those EH officers myself i strongly suggest you have a quiet word with your own local, helpful, neighborhood environmental health officer. Or at least don't be daft enough to post online your intent to fly under their radar when your home page gives your location...
i wouldn't necessarily say SFBB is appropriate for what your doing and would prefer to see a basic HACCP plan instead. You'll need to evidence control over your pasturisation and bottling process and your controls for patulin. The rest is basic good hygiene. Kick the cats out of the kitchen and have a good clean down before you start production, obviously don't let them in when producing. If they have access at the kitchen at other times it doesn't matter too much so long as you can evidence a good clean down routine before production (ie, write it down). If your business does increase dramatically though we would expect more suitable premises. You would definitely benefit from food hygiene training. Would recommend you went somewhere for half a day rather than do it online. If your local EH dept does it then go there and ask questions.
I strongly recommend you contact your local EHO and ask for an advisory visit and they'll come out and give you some helpful advice (not an inspection)!
Remember, its against the law not to register your food business. Its even more so to make people seriously ill....
