There is currently a hosepipe ban in Northern Ireland. There are no water restrictions anywhere else in the UK at the moment. Check http://www.hosepipeban.org.uk for the latest news in your area.
England hasn't seen a hosepipe ban since 2012, I hope the areas severly affected can get some respite and see some rainfall. I feel so very much for the farmers that have crops and livelihoods on the line. Allotmenteers with crops that also so desperately need water.
