I have absolutely no issue with children in need of a specialist education being fully funded for that. That is as it should be but sadly, all too often it is not thanks to budget cuts.
Private education most definitely does have a cost to the public purse though.

It is not possible to state with certainty how much the UK’s charitable private schools save through tax exemptions. However, a good estimate according to our research is around £3 billion a year. This equates to more than 6% of England’s total state school budget (£47.6 billion) in 2020-2021.

Private schools benefit financially from the tax exemptions that arise because of their charitable status. Their operating surpluses (profits) and capital gains (profits on the sales of investments including shares, land and facilities) are exempt from income tax, capital gains tax or corporation tax.
In England and Wales, private schools also receive an 80% discount on business rates (local taxes). Furthermore, they can claim 25% of all donations received (such as chancellor Rishi Sunak’s donations to his old school, Winchester College, which reportedly exceed £100,000) from the tax authorities in gift aid.
This suite of tax exemptions arose principally from a legal and public campaign conducted by the Headmasters’ Conference in the early 20th century, and have remained largely unquestioned ever since. Charities that provide education are also, under a 1977 EU Directive, exempt from charging VAT, while bequests to schools are exempt from inheritance tax.
The total scale of these tax expenditures is mostly unknown. The Labour Party estimated the annual value of VAT forgone by the state from charitable private schools was £1.6 billion in 2019. In 2021, it estimated the annual value of these schools’ business rates discount and income tax relief to be around £100m and £700m respectively. In all, we estimate the total value of private school tax exemptions could be in the region of £3 billion a year.

The fact that UK higher education is still significantly state-subsidised means, in effect, UK taxpayers continue to fund privately educated students during their university studies. Such students’ disproportionate representation is a serious opportunity-loss for state students, many of whose schools are suffering real financial hardship that negatively impacts their students’ educational and career outcomes.
