While this is true, it's a little disingenuous with regards to safe elections.

In the UK you must pre-register for a single voting location, and then when you turn up to vote they cross your name off so you can't come in again.

Sure but getting on the electoral register (to my knowledge) requires no ID either. I think this is a big part as to why postal voting fraud happens.

It doesn't require ID but is verified against other records and against the electoral register in other regions, i.e. you can't register in two different places. When housemates have moved out I have received letters asking me to re-confirm who is living in the house for the electoral register.

It might happen, but it is exceptionally rare. The impact of introducing voter ID laws would cause a far larger decrease in election validity due to voter suppression than postal voting fraud causes.
