yep, you will get pay in lieu of holidays.
They can also get you to take the holidays during your notice period.
If you have taken more holidays than you were entitled to - well that's their fault for allowing you to take annual leave you had not accrued. They will probably ask you can they deduct the holidays from your final pay - actually they might just go ahead and make the deduction without asking you, although by law they should only make authorised deductions from your pay. Your contract might outline what happens in these circumstances.
