Proven Performance Across UK Sport
Billericay Lawn Tennis Club
Before Covair, we didn't have any meaningful winter membership. But that's all changed. It means we're on a different curve to other clubs. Members usually leave during the winter, but our membership actually grows.
Lester Galley, Chairman and Director
Harpenden Lawn Tennis Club
Our tennis club purchased their first dome in 1988. We now have 3 Covair domes, which we use during the winter months. Our long-standing relationship with Covair has been very positive and they have always been on hand to help with any issues or concerns with our domes.
