Evohome HR92

Dear expert,

I installed evohome in my home but without thermostat initially.
Now I want to install them (9 in total) and therefore I want to buy 2 packs of 4 and 1 single one.
I am living in UK and my brother in law, a plumber, in France. He can buy for me HR924WE but in UK it seems that it is only HR924UK.

So are they the same and as my brother in law has preferential prices, can I buy the WE and make it work for UK?

Thank you.
