We're moving house (from London to Farnham, Surrey) sometime this summer. We haven't been able to find anything we like to buy yet so are planning to move to a rented house while we continue our search. The rented house is in the catchment of the school we'd like our daughters to go to, and we'd hope to find a house to buy in the catchment too but the catchments are very tight and the house we buy may be a few minutes further away. If we apply in Jan from our rented address and then find somewhere to buy before April, will we need to reapply with the new address, or does it just matter where you are on Jan 15th when you actually apply? What if we move between April and September (2017) when they'd start school? We don't want to get a place at the right school and then have to lose the place by moving at the wrong time! Thanks!
