Wessex Water covers the South West of England, and lets its customers order free water saving products through its own watersaving site.

Their help pages state plainly that you can “order our free water saving products online”, and that “these products are only available to water supply customers”. They suggest running their water usage calculator first so the kit matches your household.

If Wessex Water also provides your sewerage service you can additionally order free waste products, such as items to help prevent blocked pipes.
