How to pro rata annual leave

[Songbird54321]

Hoping someone here can help me work out what my annual leave entitlement should be.

My company offers 27 days annual leave, not including bank holidays, for full time staff working 37.5 hours per week Mon-Fri.
I am hoping to be working 31 hours per week but still over 5 days and won't be working the same number of hours per day so I'm having trouble working out what my holiday entitlement will be. I would ideally like to know this before putting in the request, hence me not going straight to my manager to find out.
I have googled til my eyes have gone crossed but it doesn't really seem to aimed at people who work different hours on different days.
Am I right in thinking it will need to be calculated as x amount of hours leave rather than days?
Thank you in advance

They will calculate your entitlement in hours.

27 days + 8 bank holidays = 35 days
35 days at 7.5hrs = 262.5hrs FTE
262.5 x 31/37.5 = 217hrs per year

If you are working 31hrs over 5 days that's 6.2hrs, so each time you take a day AL or for each bank holiday 6.2hrs will come off your 217hrs entitlement.

If you work 8hrs Monday and Tuesday then 5hrs Wednesday, Thursday and Friday - you deduct the number of hours you'd work that day off your entitlement.

So on a BH Monday 8hrs comes off but if you take AL on a Thursday 5hrs comes off.

Does that make sense?

This. Your leave will need to be calculated in hours

That's perfect, thank you!
Wasn't sure where I stood with bank holidays either to be honest so that helps enormously

Glad to help
