Very bad experience. Despite having prepaid the full rental fee, they rented out my reserved Mercedes to someone else because I arrived later than planned. They made me pay over 200 pounds more for a Volkswagen instead. Our group of six arrived late at night and had to continue our journey, so we had to accept it. Thankfully, with the assistance of the rental platform after returning to China, it took a month of negotiations with the UK car rental company to recover our loss.

At the car rental counter, they told me the trunk of the originally booked Tiguan was small and suggested I get a CRV diesel instead as it had a larger trunk and was more fuel-efficient. They mentioned there was a brand-new car available, so I paid an extra 300 pounds to switch. However, when I went to the parking lot to pick up the car, they said there were no CRVs left and gave me a Volvo V70 that had already been driven over 20,000 km. Being away from home and short on time, I decided to go with it. Overall, it was just okay, maybe that's typical for a small company.

Green Motion is generally very good, but the Heathrow branch is located at the Holiday Inn which is currently being used as an asylum seekers holding area by the government and feels very insecure. Be aware that the depot does NOT open at 06:00 as reported by Qeeq and Green Motion's website but at 07:00. Note also that there is no toilet on site and no shuttle service to/from the airport apart from the hotel Hoppa bus service which is infrequent.

Got stung on the fact that on didn’t have a valid UK credit card but wasn’t too much and the guy working there was super helpful and managed to sort it out for me so I didn’t have to pay crazy amounts! Very helpful! Would book again!

Great service! Quick processing and all super helpful! will definitely book again!
