The 5 best car rental companies in the UK

It might not be the sunniest place, but the UK is one of the most driveable countries. In fact, you can drive the full length of the UK in under 15 hours—it’s just 874 miles from Land’s End to John O’Groats. 

Luckily, the UK is home to some of the best car hire companies in Europe, both in major cities like London and Manchester, and in more far-flung areas. Finding the right car rental company—especially when you’re abroad—can be a real headache. It’s a competitive market, and so much choice can result in a serious case of option paralysis.

To save you time—and headaches—we’ve gone through the top car rental companies in the Netherlands with a fine tooth comb. To best compare the options, we searched each website for a 3-day midweek rental from London Heathrow, for dates two weeks out from the time of writing.

Ready? Buckle up, here we go.
