Used to do AG in the UK about 30 years ago. In those days it was simple and all you needed were 3 fairly inexpensive vessels:
A
Burco boiler which very many households had before the advent of auto washing machines, but nowadays used mostly by the catering trade - still available.
A 5 gallon white fermenter basically the same as we have today.
A 5 gallon
pressure barrel
Method:
Heat mash water in Burco. Add grains and then mash. Burco has temperature dial. You needed a false bottom and brew shops in those days would sell you one for a Burco.
Sparge and drain into 5 gallon fermenter
Discard grains and drain the sweet wort back into Burco with hop flowers (not pellets because you need to create a filter layer)
turn up the dial and Boil
Strain through hop bed back into fermenter
Ferment
Rack into Pressure Barrel and prime. Note that the pressure barrels come with a CO2 injector which takes sparklets bulbs. It's designed to keep a blanket of CO2 over the beer.
Mature for a week or so (talking about pom bitter styles here)
Drink.
Simple. However until such a simple and compact system is available in Aus I will continue to do Kits and additives and maybe a bit of partial mashing. However the UK system is really geared towards lightly carbonated top fermenting draught style pom ales and probably wouldn't transfer too well to lagers.
Edit: note that the Pressure Barrel is around $45 our money. If they were available here I'd snap up a few right now - ideal for stouts and dark ales etc. In my Bedsitter in Cardiff it just sat in the corner of the room within easy drinking distance :icon_cheers:
