Rates are often all over the map. We've seen it cut both ways. Sometimes the UK site is way lower (often even with insurance included), whereas other times, the US site is way lower. It just depends on how you hit it.

If you don't need insurance, then definitely go with the US site. You may also want to request a quote from AutoSlash. We may be able to do even better for you and you can apply your Hertz PC member number at checkout and get all your benefits.

Safe travels!
