You probably can. In order to qualify for Statutory Maternity Pay you must have been continuously employed by the same employer (in this case your Company) in the 26 weeks going into the qualifying week of your maternity, (around 15 weeks before the due date). You must also ensure your salary is above the Lower Earnings Limit for National Insurance of £6,136 (tax year 2019/20).
What you would be paid. Assuming you qualify, your Company would pay you, via the normal Company payroll system, 90% of your average weekly salary for 6 weeks; followed by £148.68 (2019/20) for 33 weeks (Your Company can reclaim this from HMRC). If you don’t meet the above criteria, you may still be able to claim Maternity Allowance.
