We aren’t just another big aquatic centre with thousands of people where you are just a number. We are an exclusive chain with a limited number of places for swimmers. We cap the number of classes and children in each class to ensure that we pay the right amount of attention to each child and their progression. We get to know both you and your child and take time to form a relationship, which in turn, makes it easier for us to teach and make sure that your child gets the most out of their lessons. This also allows us to provide the feedback that you need to help your child outside of swimming lessons.
