Proline Covers are the only independent supplier of UL classified hot tub safety covers in the UK. Our covers exceed the strict standards set by ASTM F1346-91 Standard for Manual Safety Covers.

Our covers use virgin polystyrene foam and offer the highest level of heat retention for any cover anywhere in the World. Generally speaking, if you don't see a foam weight rating and the warranty is one year or less, you can almost guarantee it's a 1lb foam cover.

We always inform of our weight ratings and we give the longest warranty. Our covers are built to last and represent "a total lower cost of ownership"

Proline covers are NOT to be confused with any other UK made spa cover - we only use exceptionally high grade materials to custom make you spa cover in ANY dimensions up to 96" x 96".
