9 Best Roof Boxes UK 2023 | Halfords, Thule and More

Thule is without a doubt the best brand for roof boxes, and the XT XL is a popular choice. In fact, it has everything you'd want a roof box to have. The slide locking system allows for automatic locking, and indicates when it's closed for extra security. Plus, it has a power grip mounting system, so you can get it up and running within seconds.

It's a good size and can hold 500 litres of luggage, or up to 75 kg. That's a nice size, but not so big that it won't fit on smaller cars. It's even been designed to have the best aerodynamics to reduce noise from the wind on motorways.

Rubber is a better material than polyester or oxford fabric, when choosing a soft roof box. That's because it's better at keeping water out and can stretch to fit your belongings. It's even anti-friction, which prevents the material from wearing down with use.

The zip is strong, and there's a wide velcro covering to keep it securely in place no matter what conditions you're driving in. Plus, it has a notably large capacity for a soft roof box, so you'll be able to fit lots inside.

This roof box is a great alternative to the Thule Motion if it's out of your budget. It has a duel opening so you can open it up from either side of the car, saving you some extra time and effort, and the lid even stays open on its own!

It's easy to install with a power grip system that allows you to attach it in seconds. And for those who find the sound of the wind distracting while driving, this box is aerodynamic which will reduce noise from wind resistance.

This roof bag is one of the few that you don't need a roof rack to mount. It comes with six built-in straps and two extras, that can be hooked over your bag and through the inside of your car to secure it. It also has a relatively large capacity that can fit up to fit four medium suitcases inside, making it a great choice for family holidays.

It has oversized zipper flaps to stop grit from coming into contact with the zip, which could otherwise cause it to break over time. It even comes with a carry bag, making it one of the easies options to store.

Are you looking for a soft roof box that's easy to mount? There are poles inserted into the base of this bag that give it a rigid bottom, similar to a hard box. This makes it simple to install and more stable when used with roof rack bars. It even has handles so you can lift the bag off and carry it inside once you've reached your destination.

The only downside is that it has a much smaller capacity compared to other boxes in a similar price range. That said, it's worth the investment, as the sturdy material is sure to keep your possessions safe!

If you're looking for something sturdier, pick this inexpensive ABS plastic roof box. It's UV protected and scratch-resistant, so it'll last a long time without becoming brittle and breaking. For additional peace of mind, you can't remove the key unless it's fully locked, which reduces the risk of any technical difficulties occurring.

It's full-width, so you'll be able to fit in more luggage than you would in a more streamlined box. Just be aware that the lid rattles a bit when in motion, but this shouldn't be too much of a problem. 

Some roof bags don't have very good weather protection, but not this one! It has UV protection to keep your belongings safe on hot days, which is ideal for the summer holidays. It comes with four fixing straps to keep your luggage securely in place, and you can even adjust them for a tighter and more stable fit.

Sadly, the material isn't the best quality and it might rip if you're travelling long distances or using it regularly. However, it is fairly inexpensive, so you can replace it easily if needed.

This roof box has the largest capacity at 680 litres! It's ideal for large families and long trips away where you'll need to store lots of luggage. This size also makes it better for larger vehicles, like an SUV. Plus, it's shock-resistant to protect your luggage from knocks during transit.

Disappointingly, the keys are plastic and the locking system isn't the best, so you'll need to double-check to see if it's locked correctly. On a positive note, you can open and close the box easily thanks to the patented spring struts.

Are you worried the roof box won't fit your car? You don't need to be, as this box has multiple mounting holes along the bottom that mean it can be easily fitted to any car. You can choose from two sizes, depending on how much luggage you have. As a rule of thumb, their 320 L box will be best for couples, whereas the larger size will better suit families.

Unfortunately, it's not as high quality as other roof boxes, and the hinges aren't very sturdy. Despite being better for occasional use, it's still a good product with an aerodynamic design that's TUV approved for wind resistance.
