Question about tax & clawback on bonus and training

I have a potential change of job. Leaving my current job would involve clawback on a bonus and on a training agreement.

Typically how is this handled for these job moves?

I could see the bonus being clawed back, from gross pay, during my 3 month notice period. (Then I’d be paid an equivalent gross amount by my new employer). Does PAYE manage this fairly well, or is there anything to watch out for?

regarding training costs being clawed back, is this typically from gross or net pay? Or do employers settle this cost directly? My concern being, there are two potential points for me to lose money:

• it is less tax advantageous if my current employer deducts it from net not gross pay
• when the new employer reimburses me, it would be taxed, meaning I’d only be repaid half the cost.

Looking for peoples experience or knowledge, this is my first time making a move at this seniority.
