I've looked around and found Drayton valves, but they are so much more
expensive, nearly 20GBP each. Is ther not a cheaper TRV that anyone can
recommend, I was hoping to pay around half that price given that I'll
need 13 valves altogether. Again thanks for your advice.

If you intend living there for a while, get the Drayton valves. Cheap ones
will last about 5 years - and one or more of them, probably less.
