Holland Park School’s story is, of course, a bit of an outlier. Most other inner-city state schools lack that kind of financing. But a new emphasis on discipline and dedicated teachers prepared to devote their spare time to extra-curricular activities mean sometimes it’s hard to spot the difference between the two sectors. And with the gap between fee-paying and state schools narrowing quickly, the merits of a ‘free’ education have never looked more appealing. Of course, the decision is made far easier by the fact that, for most, private school is now entirely unaffordable. Over the past 12 years, school fees have risen an extraordinary 49 per cent, with London’s average now £29,685 a year, while boarding schools charge an average £34,695.
