What our customers say

★★★★★

The Milu Odourless toilets we have installed in our Waterloo offices work wonderfully. I am glad we installed one in every bathroom as they certainly do what they claim!

Our brief for Wesley and the Expella team was that we didn't want the grills to look like regular fans, we didn't want any steam, and we didn't want to hear them! Pleased to say they exceeded our expectations and we're incredibly happy with the products and service received.

Clean looking and nicely detailed - an elegant balance of form and function. Smart application of automation with simple yet fit-for-purpose design that eliminates unnecessary exhaust fan running costs. All homes should have these installed in wet areas. No fuss design for a functional product - well done.

We installed several Expella fans in our new home project and we were thoroughly impressed by the quality of the fans - they do a great job! In addition, the Expella team provided excellent customer service from recommending the right fan, to supporting our builder during installation, as well as ongoing maintenance. We would highly recommend Expella fans to homebuilders or renovators.

I am reaching out to say thank you for the fantastic ventilation system.  We were having considerable problems with mould in various part of our house due to warm weather and stagnant air, which was causing us concern with two young children in the house.  Your Teams inspection and subsequent recommendation led to us installing Elicent AXC160TP fans. Since they were installed, we have not had any mould issues, now going on two years, and the fans are incredibly quiet.  Thanks again for your help, we really appreciate it.
