Roof bars are sold in three separate parts: the bars, foot packs to attach to the bars, and fitting kits that connect the feet to the roof. You may only need the bars and a foot pack if your car came with factory-fitted roof rails.
While fitting roof bars yourself is certainly an option, if you’d prefer to take the hassle out of the process then we can fit them for you.
There are three main types of roof bars: Square bars, Aero bars and Thule wing bars. Although many will universally fit most vehicles, it’s still important to check compatibility before you make a purchase.
To find suitable roof bars for your car, simply enter your vehicle registration number in our online checker. You’ll then only be shown roof bars that will fit your make and model of car.
Here at Halfords, we offer a range of roof boxes to meet every requirement. To find which one suits your needs, have a think about capacity and how you intend to use the box.
Also consider how you want it to open and what materials you want the box to be made from, as more cost-effective boxes are made from thinner plastics that may vibrate in the wind.
For more information, have a read of our buyer's guide.
First, you need to ensure that you’ve got a pair of roof bars installed as you need something to attach your roof box to. If your car didn’t come with roof bars as standard, then you can find a suitable (and compatible) set by entering your vehicle registration number in our online checker.
Fitting a roof box to those roof bars is a fairly simply process and the instructions that come in the box should walk you through it step-by-step. Keep in mind the weight capacity of your roof bars, the roof box itself and your car roof.

Drivers often underestimate how quickly a car fills up, especially when life gets busy. From sports kits and pushchairs to DIY supplies and holiday luggage, it doesn’t take much before the cabin starts to feel cramped.
Roof-mounted storage offers a smarter alternative by keeping your interior clear, maintaining comfort, and preventing loose items from getting damaged. With roof bars forming the secure base and roof boxes adding flexible, weatherproof space above, they work together to expand what your vehicle can handle without changing how it drives.
Short breaks are meant to be enjoyable and easy, and having the right storage solutions can make all the difference. Whether you’re heading out on a weekend getaway or camping trip, extra roof-mounted space can make packing luggage, outdoor equipment, and all the family essentials much easier, keeping the cabin free for passengers, pets, and improved comfort.
The added convenience means you can set off at a moment’s notice, knowing your gear is organised, secure, and out of the way. Roof boxes are one of the simplest ways to make a quick, scenic UK getaway feel effortless.

Preparing for a trip is easier when you’ve got the right travel accessories to support your plans, from secure bike carriers to practical camping gear for nights under the stars. From holiday prep to seasonal adventures, having the essentials sorted keeps your car organised and your journey stress-free. Explore the Halfords camping range for everything else you need for smooth, efficient getaways.
Adding a roof bar or a roof box may make your car measure taller and can slightly affect fuel efficiency, especially at high speeds; but for most people, the extra storage space is a game changer and perfect for holidays, camping gear, or just keeping your boot clutter-free.
Make sure your load is evenly spread and properly strapped down - no loose ends or unstable boxes. Roof bars and roof boxes are built for this, but it’s always smart to double-check everything before hitting the road. A secure load means a smoother, safer drive.
