Given all the benefits you enjoy with soft water - from lower heating bills to cleaner bathrooms - you’d be forgiven for wanting to keep them all to yourself. However, there’s a great reason, in the form of a crisp £50 note, to spread the word about water softeners. After all, your friends, family and relatives are just as likely to enjoy soft water as you, so will thank you for introducing them.

So, do your friends, neighbours and family a favour and receive £50 in the process – while bagging a year’s worth of free water softener salt for everyone you refer*.
