We want to reward you for recommending new customers to us, so here's how it works. You as an existing customer recommend someone who has yet to register and buy from Aqua Essentials. When they register and make a purchase, they leave a note on the comments section of the check out, who has recommended them (first name and last name). Once the transaction has gone through, we will send you a gift voucher for Â£10 and the newly registered customer Â£10. We like to think of it as a win win situation. You can recommend as many new customers are you like, and the more your recommend, the more Â£10 gift vouchers you receive.
