I was born in London but have never lived there as an adult and have spent the last 20 years overseas. We will know if we are moving to London in December and the actual move would be summer 2018. Our older child would be looking to join Year 3 September 2018. My preference would be a state primary, if that's possible. I'm not sure what is relevant but he does't hold a UK passport and I'm not sure when we would know our London address, we wouldn't actually be living there until the summer.
So, is there anything I can do in advance? Should know in advance?
Thanks.
