I think it differs everywhere, so best thing is to check your maternity policy with your HR dept. I get 90% pay for 6 weeks, then 50% pay plus statuatory for a further 12 weeks, then just statuatory for a further 21 weeks. So, a total of 9 months, but I can of course go back earlier if I want to. I do know that the 50% pay given for the 12 weeks is subject to you returning to work (can be part time) for at least 3 months after maternity leave. If you do not return, you have to pay this money back. I plan on returning part time so no issues there.
