Salary Query re starting new job

[tadpole73]

I work in a school and I'm handing my notice in on Tues 17 Jan. As I have to give a calendar month's notice, my last day will be Friday 17 Feb, but as it's Half Term from
Mon 13 Feb - Fri 17 Feb, I will get paid for the school holiday. However, my new employer wants me to start Weds 15 Feb, so am I allowed to get paid for 3 days (15th-17th Feb) by both employers or will it cause issues?

The only issue I can see is potentially with your tax code

YerAWizardHarry - yes, I was wondering that. Once I got my P45 on 19th Jan when I get paid, would it then get sorted out?
The new pays me on 25th of every month, so on the 25th Jan

You’d have 3 days of a second job so you wouldn’t get any personal allowance on the new job until after you leave your first. HMRC aren’t the quickest so it’s more likely your whole first pay in the new role would be taxed with no tax free allowance then sorted the next month or so (less the 3 days).
