Re: Truly the Best
"Apart from moving house/business to a completely different watershed, is [choosing who provides your water bills] really possible?"
Excellent question, and, unsurprisingly given the context, the answer depends on whether your supply is for a business or a home, and whether it's in Scotland or somewhere else (But the other AC seems to have omitted these minor details).
https://www.scotlandontap.gov.uk/ says
"Scotland is the first country in the world to offer non-household customers choice in their water supplier.
Since 1 April 2008, all 130,000 businesses, public sector, charitable and not-for-profit organisations in Scotland have been presented with a variety of suppliers to choose from.
Business water rates are now competitive, and the introduction of competition in the water industry in Scotland has brought wider choice and more tailored services, and is leading to lower prices."
Meanwhile in England and Wales it's still business as usual - your residential water supplier is (in general) determined solely by your address, and until very recently the same applied to most non-residential supplies in England.

"In April 2017, the largest competitive water retail market in the world opened for business, bringing the biggest change to the water sector since privatisation.
This new market means 1.2 million businesses, charities and public sector organisations in England are no longer restricted to buying water services from their regional monopoly. Instead, they can shop around, renegotiate, and find the right deal for them. If customers don’t like the service they get, they can take their business elsewhere.
This market could deliver lower bills, help people use less water, lead to improved services, and see new offers and bundles emerge."
And business pigs could fly. If there were such a thing as flying pigs.
