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.

Frequently Asked Questions
How quickly can a seasonal dome be removed for storms?
Our unique rapid deflation system allows complete removal in under 4 hours when severe weather threatens. This is a safety advantage exclusive to Covair domes and one of the key benefits of choosing a seasonal solution over a permanent structure. When Storm Eunice threatened, our team at Manchester City FC's training ground safely removed the dome in just 3 hours.
What happens to the dome in summer?
The dome is professionally dismantled and stored on-site, typically in a shipping container or storage shed. Our DomeCycle™ service handles the entire process, with removal usually completed in a single day. This means your courts, pitches or range return to full outdoor use for summer, preserving the authentic open-air experience your members and players prefer.
Can we heat a seasonal dome?
Yes. Optional heating units (200–500kW) can be integrated to maintain comfortable playing temperatures throughout the winter. That said, many facilities find the dome's natural insulation properties and continuous air circulation sufficient for most UK winter conditions, keeping energy costs to a minimum.
How long does the membrane last?
Polyethylene membranes typically last 10-15 years with proper maintenance, whilst PVC membranes last 15–20 years. Regular professional cleaning through our DomeClean™ service and correct seasonal storage both play an important role in extending membrane life. We'll advise on the best membrane choice for your facility during the consultation process.
Do we need planning permission?
Usually yes, but seasonal structures often benefit from simplified planning processes because they are classified as temporary. We provide full documentation and planning support as part of every project, and with extensive experience working with UK planning authorities, we know how to make the process as straightforward as possible.
What about insurance?
Seasonal domes are typically added to your existing buildings insurance policy as temporary structures. We provide all the documentation your insurer will need, and most of our clients find the process simple and cost-effective.
Can the dome be relocated?
Yes. Seasonal domes can be dismantled and relocated to a different site if your needs change. This flexibility is a significant advantage over permanent structures and protects your investment for the long term.
