NHS query - payrise back dated but qualifying weeks were before this

[Loudandclear]

I have been given a pay rise as everyone has in the NHS and I was paid this month my new salary with the back dated pay (from Apr 2022). However I'm now past my qualifying weeks for mat pay - will my mat pay be based on my old salary, even though I was in theory on my new salary as backdated?

I'm in the same situation, I just assumed I was going to miss out on the payrise as they took so long to implement it. Will be interested to know if anyone knows anything different...
