You should get your full normal pay if you work during your notice period. This should include any work benefits, such as pension contributions, bonusses, free meals, etc.
If you’re off sick or on maternity leave, paternity leave or adoption leave you’ll only get whatever you would have been normally paid in those circumstances. For example, you might only get statutory sick pay if you are off sick.
If you are on holiday, you should receive your normal holiday pay which should be no less than your usual wage.
