If you are continuing to work during your notice period, you are entitled to the payment of your wages as normal and in accordance with your contract of employment. This would include entitlements to overtime, shift premiums and other bonuses.
Provided you have not been dismissed without notice on the grounds of gross misconduct and your employer is paying you in lieu of notice rather than requiring you to work your notice, you should be paid your normal contractual rate of pay during this period.
The period of paid notice you are entitled to will be the longer of your statutory notice period and the period of notice set out in your contract. In the event of absence because of sickness, you are entitled to full pay, where the employer gives the statutory notice.
