Rental Car In UK At Age 21???

[Playmaker]

Some friends and I will be flying into Newcastle, UK on August 3th to travel throughout Scotland for a few days. One of my friends turns 21 on August 4th and we were hoping to rent a car on that day. I thought most rental car places were 21 age limit, but I checked Hertz and it's 23. Does anyone know of a rental car company that will rent out of Newcastle to a 21 year old? Or is the 23 age limit standard in the UK? Thanks.
