Fantastic support before, during and after our purchase. Simon was very helpful recommended what we needed for our current setup, and even after when we were having a few teething issues he was always on hand to assist.

Helpful and informed

Graham Chester (verified purchase)

Nick was very helpful in sorting out a query we had about a pool bypass kit and how to install the kit. Sent us a diagram by email following a useful telephone conversation. We have now installed a bypass kit and are delighted it’s fully working. Thank you for your help.

Great Service

Great service from the outset. Communication was spot on, and the engineers that attended were informative and pleasant. Can't fault anything from start to finish.
