At the moment HMRC seem fine. No big costs. Plenty paperwork + Just a bit bemused where our 'brewing plant' is,,,, Try to explain it's going in a mezzanine above the bar after ripping out redundant water tanks. Our current duty suspense/conditioning store is two 23l cornies and 8 x 5l mini kegs. Biggest outlay is two Reeves posh hydro's and thermometer with certification. Brewing day book and monthly return could be the main pain. Brewing industry friends say JFDI. HMRC are fine if you do your research and document. Already have HACCP / Eatsafe awaiting EHO visit,,,,,
