University of Bristol teaches Haskell in the first year (along with C, Java and a Prolog varient called Frill) if you're doing CS or CSE (Computer Systems Engineering, four year mix of CS and EE).

I wouldn't be surprised if Oxford and Cambridge both teach it as well since last I looked (well over a decade ago now) their CS courses had a heavy theoretical slant and Haskell and the Lambda calculus go together well!

I'd imagine that the likelihood of being taught Haskell at university correlates well with the university treating CS as an offshoot of it's maths department.
