Not a problem with the questions Karen.
The local council and environmental health have been really good. We invited them around before we started to talk through what we planned and they suggested a few things. They have been very helpful right from the start.
I would say it is well worth contacting them before you do anything.
I'm not sure you would be able to cope with just standard fridges if you are cutting whole pigs. You would need somewhere to hang the carcasses when you bring them back from the abattoir.
I have 3 standard freezers in another part of the building which I use to store pork and lamb.
Hope this helps, let me know if I can answer anything else.
