Car covers: indoor or outdoor, and how to choose one

Choosing between an indoor and outdoor car cover depends on where you keep your vehicle and the level of protection you need from dust, moisture or UV rays.

Deciding between indoor and outdoor covers

Indoor covers focus on keeping dust and minor scratches away in a garage or storage unit. Outdoor covers add waterproof layers and UV protection for vehicles left outside. Consider how often you use the car and whether it sits for weeks at a time. A breathable indoor option suits regular garage parking while a heavier outdoor model handles rain and frost better. Many drivers keep both types for different seasons. Think about your daily routine and how much time the car spends parked before deciding on the main cover type.

Materials and protection levels

Look for breathable fabrics that reduce condensation. Oxford fabric and PEVA options offer good water resistance while allowing air flow. Layered materials give extra durability against rain and frost. Aluminium film versions reflect heat and light during warmer months. Choose thicker options when parking under trees or near building work. Always check the hem and stitching for strength before buying. Different fabrics suit different needs so compare the weave and coating when selecting one for long term use.

While the cover protects the body, our windscreen care essentials help keep the glass clear.

Fit and size considerations

A well fitted cover stays in place during wind. Measure your car length and choose universal or half covers that suit your model. Elastic hems and straps help secure the cover properly. Half covers protect the windscreen and roof without covering the whole vehicle. Universal sizes work across many makes while custom fits reduce flapping. Test the cover on your car before relying on it long term. A loose cover can cause damage so take time to match the shape and length to your vehicle.

Weather specific advice

In winter months a frost or snow cover protects the windscreen and reduces morning clearing time. Summer calls for UV resistant fabric to prevent paint fade. All season covers handle both ends of the spectrum. Pair a cover with a dehumidifier bag inside the car to control moisture during damp spells. Check the cover after strong winds or heavy rain for any damage. Seasonal changes in the UK mean having options ready helps keep the car in good condition throughout the year.

In frosty weather, a magnetic windscreen frost cover saves scraping in the morning.

Care and storage of your cover

Shake off loose debris before folding. Store the cover in a dry bag when not in use. Regular checks for tears keep the cover effective over time. Wash fabric covers gently with mild soap and allow them to dry fully before packing away. Avoid dragging the cover across the paintwork when fitting or removing it. Proper care extends the life of the cover and keeps it ready for the next season without extra cost.

Caravan and motorhome covers

The same choice applies to caravans and motorhomes, only bigger. A fully waterproof cover keeps rain off but can trap condensation against the bodywork if it cannot breathe, so for a caravan that sits outside for weeks a breathable, water-repellent cover is usually the better buy: it sheds most rain while letting moisture escape. Look for an elasticated hem, tie-down straps and a zip so you can still get through the door.

Measure before you order. Take the length from the two longest points of the body, including the spare wheel, bumpers and any ladder but not the hitch, and the height from the ground to the roofline. Our breathable 3-layer caravan cover comes in three sizes for caravans from about 5.2 m to 7 m long, with a size table on the product page.

For long stays in storage, a solar battery trickle charger helps keep the battery topped up.
