Very sensitive topic, I know, but curious to see who has or would do this. The school in question has an admissions policy that doesn't prohibit this (just says the address must be your permanent address and you need a child benefit letter with that address and letter from a professional confirming the same but no rules about having to live there for X number of years in advance). IF we did do this, we would rent for at least 2 years in the area and may move there eventually anyway but just seems massively risky to me that someone will query it. I know quite a few people who have done this or intend to do it though so clearly some people think it's ok!
