I'm going to say
Pycrete (in a container)
you do the google for it,
I can't be bothered to.

Year-round ice cellar
Pykrete-bricked cellar for year-round, energyless food storage

Pykrete is a building material developed in the last century. The recipe is 18% sawdust, 82% water. When frozen, it makes a sound building material and insulates itself well.

During WWII, the allies were planning on making "floating landing grounds" ( aircraft carriers) out of this stuff. In the cool ocean water, ships made out of pykrete melt very slowly, like icebergs.

If you're into low-energy living, you can build a root cellar, and line it with pykrete bricks to make it a refridgerator.

At a certain point underground, the ambient temperature stays around 52 F, perfect for storing fruits and vegetables. This was the technique used by American pioneers.

Through in a few pykrete blocks, and you've got an ice-room!

not much info on were to get it (if available to public), or how much does it cost

Wait, here's one DIY if anyone is interested

"This was the technique used by American pioneers"

and if they had air con units they WOULD HAVE USED THOSE!!!

"18% sawdust, 82% water..."

wood + saw = 18% of it....
Tap = 82%

and it'll cost you very little

I know nothing about economics in the British Isles. Nevertheless: Nothing beats air conditioning! In the U.S. a $100 to $!50 at Sears and Roebuck catalog online will buy a small room a/c. It is large enough to cool a small 10' x 12' room to near 60 degrees farenheit when it is 115 degrees farenheit outside. Sorry I can't translate to pounds and Celsius. It would also greatly reduce the temperature in a larger room. Nothing beats walking into a 75 degree room when it's 100 degrees outside!! B) I hope I'm not being impossibly ignorant.
