Some good points thanks for taking the time to reply and offer assistance. Here’s my thoughts:
NO function in the business? Not reallyNo office space? Nope, but even if there was office space it wouldn’t make my house a commercial property, I work form home sometimes in my employment and this doesn’t make it a commercial property.No reception of guests? NopeNo cooking, since you are doing B & B? Nope self cateringNo disposal of waste or rubbish? Potentially, this is a consideration.
I think speaking to the relevant authorities would do no harm as suggested. Regarding doing things underground, I really don’t intend to significant capital in an unregistered business and then advertise it online
