The Algarve’s climate is wonderful for pool owners. More than 300 days of sunshine each year, warm evenings that stretch well into October, and enough heat in summer to make a pool genuinely essential rather than decorative.
But that same climate creates specific pressures. Evaporation is relentless. UV degradation accelerates. Atlantic winds can lift an improperly secured cover clean off its moorings. And the coastal air carries enough salt to corrode inferior metalwork within a season or two.
We have been installing automatic pool covers across this region since 2008. Eighteen years gives you a reasonable sample size. You see which systems hold up and which ones require constant attention. You learn which features clients actually use and which they pay for once and ignore forever. And you develop a clear sense of what works in Algarve conditions specifically, not in theory or in some other climate zone.
This is what that experience has taught us about automatic pool covers here.
Why Automatic Covers Make Sense in This Region
A manual pool cover works perfectly well if you remember to use it. The trouble is, most people don’t. It sits folded in the equipment room, or draped over the side of the pool house, because pulling it across the water and securing it properly takes ten minutes of awkward physical effort that nobody feels like doing at the end of a long day.
An automatic cover removes that friction entirely. Press a button. The cover deploys or retracts in under two minutes. That ease of use is why our clients who install them actually keep their pools covered when they should be covered, which makes everything else (heating costs, chemical consumption, cleaning time, evaporation losses) measurably better.
The Algarve adds particular urgency to this. Evaporation rates here are high. A medium-sized uncovered pool can lose 4 to 6 millimetres of water per day in summer. That is roughly 10,000 litres per month for a standard 8×4 metre pool. Water supply pressures continue to increase across the region.
Cover the pool and evaporation drops to near zero. The reductions in heating and chemical costs make the investment worthwhile over time.
The Systems We Install (and Why)
We fit automatic pool covers made by DEL, a French manufacturer that has been producing pool safety equipment since 1975. DEL is part of the CF Group, based in Brittany. The company holds NF P 90-308 certification, which is the French safety standard for immersed pool covers.
The specific model we install most often is the Brittany, an immersed slatted cover system. The slats are polycarbonate, reinforced with UV inhibitors and designed to withstand the intense sunlight common here. The drive mechanism uses a tubular motor mounted in a submerged housing at one end of the pool. The cover rolls and unrolls on a fixed axle, guided by tracks set into the pool coping on either side.
Why DEL rather than one of the several other European manufacturers? Two reasons. First, parts availability. We keep replacement slats, drive motors, and control units in stock locally, which means repairs happen quickly when needed. Second, the engineering is straightforward. We have been working with these systems long enough to diagnose and fix most issues without waiting on factory support.
DEL covers are not the cheapest option available. They sit in the upper middle of the price range. But they are well-made, they hold up in coastal conditions, and we can service them properly. Those three factors matter more than initial cost over the lifespan of the installation.
What NF P 90-308 Certification Actually Means
The NF P 90-308 certification is worth understanding, because it defines what a pool safety cover is supposed to do.
The standard requires that the cover can support the weight of an adult (100 kilograms minimum) without collapsing or allowing submersion. It mandates UV resistance testing to ensure the material will not degrade dangerously after prolonged sun exposure. And it specifies that the cover must integrate with the pool’s filtration and chemical treatment systems without creating dead zones where algae can grow unchecked.
This is not a marketing designation. It is a legal safety standard enforced in France and recognized across the European Union. Covers that meet it have been independently tested and verified. Covers that do not meet it should not be described as safety covers, regardless of what their promotional materials claim.
In Portugal, pool safety equipment is not yet subject to the same regulatory framework that exists in France. There is no legal requirement to install a certified cover. But the physics of child safety do not change at the border. A cover that meets NF P 90-308 provides verifiable protection. One that does not is a convenience feature with uncertain safety characteristics.
We install only certified systems.
Safety Performance (The Part That Actually Matters)
The primary reason to install an automatic pool cover is safety, particularly for families with young children. Drowning remains one of the leading causes of accidental death for young children in Portugal, with the majority of incidents occurring in private residential pools.
A certified automatic cover provides a physical barrier. When properly closed, it will support the weight of a child (or an adult) who falls or walks onto it. This is not theoretical. The NF P 90-308 standard includes load-testing requirements specifically to verify this capability.
But the cover is only effective if it is actually deployed. This is where automatic systems outperform manual ones decisively. Our clients use automatic covers consistently because they are easy to operate. Manual covers, even high-quality ones, tend to be left open or only partially secured because deploying them is inconvenient.
One important clarification: a pool cover is not a substitute for proper supervision or for perimeter fencing. Portuguese law does not currently mandate pool fencing for private residences, but we strongly recommend it. A cover provides one layer of protection. Fencing provides another. Used together, they significantly reduce risk.
For clients concerned about child safety, we also supply removable mesh safety fences manufactured by SafetyKids in Spain. These meet both NF P90-306 (French standard) and CTE SU1/SU6 (Spanish structural codes). The combination of an automatic cover and a perimeter fence gives the highest level of protection currently available.
Who Benefits Most from Automatic Covers
We install automatic covers for three types of client.
First, families with young children or pets who prioritize safety above all else. For them, the certified load-bearing capacity and ease of deployment justify the investment regardless of operating savings.
Second, holiday home owners who are not on-site year-round. An automatic cover keeps the pool clean and protected during absence periods without requiring manual intervention. Several of our rental property clients now list automatic covers as a premium amenity, which seems to resonate with guests who have young families.
Third, clients who heat their pools and want to reduce energy consumption. The heating savings alone often justify the investment over time.
If you fall into one of those categories, the case for an automatic cover is strong. If you use your pool only occasionally, do not heat it, and have no particular safety concerns, then a good-quality manual cover may serve you adequately at lower cost.
The Question We Get Asked Most
Do you need an automatic cover if your pool already has a manual one?
The honest answer depends on whether you actually use the manual cover. If you deploy it consistently every evening and after each swim session, then it is doing its job. The automatic version will save you time and effort, but the functional benefits (evaporation reduction, heat retention, debris exclusion) are the same.
If the manual cover spends most of its time rolled up and unused because it is inconvenient to deploy, then switching to an automatic system will change your pool’s operating costs and cleanliness measurably. You will use it because it is easy to use. That is the entire point.

Frequently Asked Questions
What is the typical lifespan of an automatic pool cover in the Algarve?
The slats last 8 to 15 years depending on UV exposure. The motor and drive mechanism typically last 10 to 12 years. With proper maintenance and periodic component replacement, the overall system can remain functional for 15 to 20 years.
Can automatic covers be installed on existing pools?
Yes. Most automatic cover systems can be retrofitted to existing pools, provided the coping is in good condition and there is sufficient space for the guide tracks and motor housing. We assess each pool individually to confirm compatibility.
Are automatic covers safe for children and pets?
Covers certified to NF P 90-308 are designed to support the weight of an adult without collapsing. They provide a physical barrier that prevents accidental submersion. However, they are not a substitute for supervision or perimeter fencing.
Do automatic covers work well in coastal areas with salt air?
Yes, provided they use marine-grade materials. The DEL Brittany systems we install feature stainless steel fittings and powder-coated aluminium tracks designed to resist corrosion in coastal environments.
What happens if the cover gets stuck or jammed?
Most systems include manual override capability, allowing you to retract or deploy the cover by hand if the motor fails. Obstruction sensors on higher-end models stop the cover automatically if debris is detected in the tracks.
