No queue, and the airport shuttle bus is very convenient.

We arrived at HERTZ earlier than the scheduled pickup time, and they didn't have the reserved model available. The staff said we could only choose either a fully electric car or a manual transmission vehicle, or pay double the order price to upgrade to another option. I refused and suggested waiting to see what could be done. After waiting for nearly two hours, a senior employee helped us by offering a smaller SUV model compared to what we had booked. I had reserved a compact SUV capable of fitting three 24-inch suitcases in the trunk, but we were given a subcompact SUV where only two 24-inch suitcases barely fit. After storing the luggage, there was hardly any space left—even a large bottle of mineral water couldn't fit. I've rented cars abroad five or six times before, and this was the only instance where the rental company downgraded the car model. The service at the HERTZ Heathrow Airport branch is genuinely poor. However, the vehicle itself was in good condition—very new with only a few thousand miles driven.

Huge scam!!!! They said there were no issues when I returned the car, but when I got back home, I received a damage fine, even though I had full insurance. What made me the most angry was the Hertz staff. In Edinburgh, we paid for parking but still got a fine. After returning the car, we went to the front desk to discuss how to handle it. Initially, the Hertz employee was very nice and asked us to send the ticket and our parking receipt to Hertz, promising they would handle it. But then, all of a sudden, they changed their tune and told us to pay the fine first, saying they would help us get a refund from the city council. They even made us pay the fine right there on the spot, despite us risking being late for our flight. After paying, the Hertz employee immediately became hostile and ignored us, serving other customers instead. It felt very intentional and extremely frustrating, like something out of a TV drama. When we got angry and demanded an explanation, they said it was not Hertz's responsibility and we should deal with it ourselves! Later, we realized it was a trick. By making us pay, they shifted the dispute to be between us and the Edinburgh government. To appeal the fine, we would need to provide the car owner's information, but we couldn't process it without that. Only Hertz could resolve this mistake, but to avoid hassle, they tricked us! Otherwise, they would have been charged, and we would have had to provide proof, making it a dispute between the car owner and Edinburgh's government. Sadly, when I was studying in the UK, I heard about how bad Hertz staff were, and many people preferred to choose Europcar even if it was more expensive. Now I've seen it for myself, what a terrible company. The service is extremely poor, whether picking up or returning the car! PS: We waited forty minutes for the Hertz shuttle at the airport!

The service was average. When customers encounter problems, the resolution speed by the relevant departments is very slow.

It's advisable to buy car insurance when you rent the car, as it is more expensive if you purchase it upon picking up the car in London. Also, it's not recommended to buy fuel when picking up the car (80 pounds) unless you are only driving in London, as fuel is cheaper outside of London.
