Where can I get glass tanks in the UK

[Pin]

Looking to buy a 75 gallon/280l glass tank for my hamster but I dont want to pay an extortionate amount like pets at home are asking.
I dont want the cupboard units either, just a tank.

Rn my ham is housed in a 115x50cm cage but its made of wood and while im not worried about him chewing through it (its thick wood) its waking me up all hours of the night as we have to share a bedroom ^^"
I thought about buying the marakesh cage on zooplus as theres nothing for him to get his teeth into, but its slightly smaller and It seems unfair to downgrade on his size just so I can sleep.
