Sounds like they're on-prem:

The computers are submerged in mineral oil that captures heat that gets transferred into pool water with a heat exchanger. The pool still has a gas boiler to boost the water's temperature if required. Deep Green claims it's transferring about 96 percent of the energy used by its computers and reducing a pool's gas heat usage by 62 percent. Deep Green is paying the Exmouth Leisure Centre for all the electricity its data center uses, as well as any setup costs, and the Exmouth Leisure Centre gets the heat for free.

I assume Deep Green is also paying for the networking, but I notice they don't mention that they're paying for space? So free heating in exchange for free colo space?
