Hi Masquedefer Curran,
In order to qualify for the full starting rate for savings allowance, you will need to earn below the basic rate of income tax threshold.
This is currently £12570.
If you earn under this amount, you can earn an additional £5,000 in interest tax free.
However, for every £1 you earn over this amount, you lose £1 of the starting savings rate allowance.
Please have a look here for more information:

From the informatin provided, the starting rate for savings would be £5000.
The maximum you can pay into your pension scheme is £3600.
Thank you.
