Solar cover or pool cover: which should you buy?
Updated: 2026-10-22
You have typed “solar cover or pool cover” because both names sit on the same amazon.co.uk results, and you are about to order one for a garden pool this weekend. They share a search and not a job. A solar cover is bubble film that floats on the water to slow evaporation and hold some of the sun’s heat. A debris cover is a sheet you tie over the pool so leaves and weather stay out. Updated on 20 October 2026, this page uses public UK sources and amazon.co.uk listings, not a lab test. A qualifying purchase can earn a commission at no extra cost to you. If you already want the film, use the [solar pool cover comparison](/hub/swimming-pools/solar-pool-cover).

A solar film floats on the water
A solar cover, often called a solar blanket, sits on the surface. The bubbles trap a thin layer of air, so less heat leaves the water and less water leaves as vapour while nobody is swimming. SPATA, the Swimming Pool and Allied Trades Association, describes a solar blanket as the cover for evaporation and sun, and estimates that an uncovered pool can lose about 90 percent of its heat. That figure is SPATA’s estimate for a pool with nothing on it, not a measured result for a blanket on amazon.co.uk.
The film is not fastened. Pool Warehouse, writing about above-ground covers, says a solar blanket is used through the season and is not tied down, so wind can move it. On a round Bestway, one gust can slide the blanket aside and leave a crescent of open water. You pull it back by hand. Pegs and a drawstring belong to a sheet that goes over the pool, not to film on the water.
Bestway’s bullets often say the film keeps debris out. A few dry leaves can sit on the bubbles until you lift the cover. Compared with a roped sheet, the film is a weak barrier in a gale. Leaves in that wind are the sheet’s job.
A debris cover is tied over the pool
A debris cover is the tarpaulin most people mean by pool cover. It goes over the top of the pool, and a rope, pegs, or water bags hold it there. The material is the clue: PVC, braided PE cloth, or a heavy Oxford weave such as 420D, with a hem and a cord. That cloth is not bubble film. It will not do the heat job you wanted from a solar cover.
Amazon titles still print solar on black Oxford tarpaulins and other cloth sheets. A UK review of one cloth cover we removed from this comparison said it was not solar and did not keep the water warm. We do not name that listing. Braided cloth and Oxford are the other category.
Those sheets are compared on the pool cover page, not here. SPATA’s factsheet, written for a permanent pool rather than a Bestway you pack away in September, describes a winter debris cover as a mesh that lets rain through, or a PVC sheet held by water bags. That mesh is not the tied PVC or Oxford sheet on the sister page. If you want a cover for leaves, start there, and open the solar pool cover buying guide only once you have chosen the film and need a size.
Use both only when you can tie a sheet
You want the film when the job is warmer water in a pool you will swim in this week. You want the debris cover when the job is leaves, rain, and a rope. They do not stand in for each other.
The film then stays on the water between swims, and the sheet goes above it when nobody is swimming and you want leaves kept off. An Intex UK review describes one owner using a solar cover and a separate cover. That is one person’s routine, not a rule, and not a test we repeated.
Buy both only if the pool has somewhere to tie a sheet and someone will take the film off before anyone swims. A smooth top ring with no eyelets cannot take a rope. Leave the bubble cover on while people climb in and you have blocked the water, so fold the film off first. The guide to fitting a solar pool cover sets out how the blanket goes on and comes off. Neither cover is a safety cover: a floating film will not hold a person, and a tied sheet is for debris, not for an unattended child.
At the end of the season, store the film
Oasis’s above-ground care notes say to use a solar cover whenever the pool is not in use. If the pool stays up over winter, take the solar cover off, clean it, store it, and fit a winter debris cover. That winter cover is a third product, not the bubble film left on through January.
A lot of UK garden pools come down in September. SPATA’s factsheet assumes a permanent pool. A Bestway you deflate and box does not need a winter mesh once the water has gone. Dry the film and keep it out of a hot place until you fill the pool again.
If the frame stays up with water in it, leaves and rain belong on the pool cover comparison. Buy the film when you will swim this week and want the water to hold heat. Buy the tied sheet when you need leaves, rain, and a rope. Buy both only when you can tie the sheet and you will lift the film first.
Common questions
Will a solar cover stop leaves?
A solar cover can hold a few dry leaves on the bubbles, which is why some Bestway listings say the film keeps debris out. Wind can still shift it, and wet leaves blow under the edge. Compared with a roped sheet, the film is the weaker barrier. If leaves are the job, choose a debris cover.
Will a tarp warm the water?
A tied tarp in PVC, PE cloth, or Oxford keeps leaves and weather off the pool. It does not float as a bubble blanket, and it does not do the evaporation job SPATA gives a solar cover. One UK review of a cloth sheet said it was not solar and did not keep the water warm. For warmer water this week, buy the film.
Can I use a solar cover and a debris cover together?
Yes, if you can tie the sheet and someone will take the film off before swimming. The film stays on the water between swims. The sheet goes over the top when nobody is in. An Intex UK review describes one owner doing that. It is one routine, not a rule, and it fails if either cover stays on while people climb in.
What goes on if the pool stays up all winter?
If the pool stays up with water in it, Oasis says to remove the solar cover, clean it, store it, and fit a winter debris cover. That is a third product. A Bestway packed away in September does not need one. SPATA’s winter note is for a permanent pool, not film left on through January.
Why do Amazon titles say solar on a black Oxford sheet?
Sellers put solar on sheets of 420D Oxford or braided cloth with a rope. The word does not change the material. Bubble film is the solar cover. Woven cloth with a hem and a cord is a debris cover, compared on the pool cover page rather than in the solar ranking. Read the material line before you order.
