You can use the EY3 form to inform Ofsted about 'certain changes to individuals, including names, addresses and any start or leave dates.'

It can be printed and sent to Ofsted - it is not available online -

You use the Govt gateway to complete the EY2 form to inform Ofsted about new staff or 16 year olds with a new DBS and to input your SEF -

I hope that helps
