Nobody knows when exactly and how at this point. Nobody knows if it will capture prepaid specific schemes either. I bet it won’t in many cases. Remember that the top lawyers in the country probably use private schools.
What is clear to me though is that this policy would cost state finances money not the opposite. People with kids who would have paid for private primary will go state now and into the best catchments at that. If your catchment for an outstanding school was 0.5 miles it is about to shrink again. The lowering birth rate is irrelevant when it comes to the most sought after schools, they are always oversubscribed especially at secondary level.
There might be some cash generated via relocations and stamp duty. Politicians love any policy that may ignite the stagnant housing market…
Parents will move their DC at 11 plus and 16 plus into top state schools. Parents who thus far self funded more severe SEN will employ lawyers to get EHC in place.
Some private school teachers will lose their jobs.
Private tutoring and after school learning will boom - some provided by companies from other jurisdictions paying tax there. Parents and companies will invent tech to create the same advantage.
Overall most likely outcome will be an even bigger difference between top state and worst state schools and more and selection at 11 plus via the back door through academies (music, sport, language aptitude places etc). Academies are essentially private schools but funded by the state and just have to follow a few more laws than private schools eg Admissions and Exclusions.
In the shorter term, professional women will cut their hours to navigate the new landscape.
There will be a negative impact on the mental health of children, their parents and teachers and staff. As a society we should know by now that mental health impact costs productivity long term. This will include children in the state sector who don’t make their GCSE grades to stay on at Sixth Form because the places will go to ex private school kids (or those tutored online/with supportive apps).
In a system where you can already buy advantage via catchment or grammar tutoring or just tutoring prep for top set, which most privileged parents do anyway, scratching at the fringes and attacking some private school teachers and maintenance staff is dumb at best. So it is either sheer stupidity or a deliberate culture war.
They don’t have the budget to actually make the state sector more equal so they have chosen a policy to pretend they are doing something that tricks the everyday voter into believing something will change. The fact that it will have the opposite effect and they must know that deep down is neither here nor there. Welcome to a deja vu of 21st century British politics. Ineffective disingenuous liars.
In any event, given the geopolitical situation with Russia and Israel and the US election etc and ours shortly after who knows what is actually going to happen in the next 12 months. We are meant to go into a more hopeful prosperous post Covid era but it seems the powers to be across the world have chaos in mind.
This is small scale chaos bomb aimed at the private school sector. How dare the teachers there have continued teaching online during Covid. Time to pay for promoting excellence and setting standards that the state cannot match. if you cannot afford to bring the state sector up, you aim to bring the private sector down. Nevermind a few casualties of some kids with minor SEN, stressed out parents, those who paid who wanted better for their DC than what they had, numerous teachers, ground staff, local smaller communities in more remote areas.
It is conceptually different if private schools price themselves out vs a deliberate targeted attack by a government which is an anomaly worldwide, the latter is personal. When things are personal the fall out is inevitably unpredictable and creates a lot of hate. They will just be creating a generation of families who will never ever vote Labour due to personal experience. I don’t think making politics this personal is a good idea.
