The fridge only spread into common ownership in Britain during the 1970s
Although some posh people had fridges and even domestic freezers before the 1970s, you are quite right 'flecc' that it wasn't until the 70s and later that they became de rigueur in modern kitchens.
My late wife managed a frozen food store, 'Bejam', since subsumed by 'Iceland', back in the early 1970s. Not only did Bejam sell food, they also sold fridges and freezers and had done since the company's inception in the late 60s.
In those days, we didn't have a freezer but one day I arrived home to find a chest freezer in our kitchen. My wife explained that an elderly lady had come into her shop to purchase a modern upright freezer to suit her new kitchen in her rather grand house. She insisted that her old freezer was taken away by the delivery people so it was duly taken back to the shop and placed with other old traded units in the back storage area awaiting disposal.
Because the delivery chaps reported that the freezer had had to be emptied on their arrival so was clearly still working, the lady wishing to keep her food cold to transfer into the new freezer as soon as it was up and running, my wife determined that it was too good to scrap and would fit neatly into our fairly large kitchen!
There was a curious thing about it though in that it didn't have one of the recognisable names on it and the lady who had owned it apparently for several years referred to it as a 'conservator', rather than a freezer. I later discovered it was American and manufactured by a firm called Crosley.
We used it for a couple of years and on moving into a new home with fitted fridge-freezer, it lived on for a few more years in my garage. Going off at a tangent, although we always bought milk from the supermarket back in the 80s, we were the 'odd man out' as the street I lived in then had a large old people's home and external maisonettes for the more able elderly. Most other residents of that street had their milk delivered in glass bottles because Express Dairies still delivered by electric milk float to the neighbourhood including the old people's place.
Ah, nostalgia's just not what it used to be!
