Just to clarify:
The hosepipe ban is now in force for 20 million users.
I've read some threads saying you can clean domestic but you can't clean commercial, or the other way round etc.
Just to help anyone who may be getting mixed up, these regulations are written to property owner, be he commercial or domestic. They are asking the property owner to refrain from using a hosepipe.
We, as windowcleaners can go and clean the windows of a domestic or commercial, or any premises, it's our livelihood.
