I did Google, although not particularly hard given the answers were provided to HoC questions on CEA funding last year, and in an FOI to the MoD in January 2024.
In the year 2022/23 the cost of CEA to the MoD was £84.59 million covering 4,210 children. (HoC written answer 20 April 2023).
An FOI shows that this figure has remained relative constant at around £80 million - £85 million per year over the last 10 years, with the exception of 2013/14 (£89 million) and 2016/17 (£103.5 million).
As for FDCO CEA payments, in the financial year 2022/23 the cost of CEA was £13.8 million for 514 children in boarding schools in the UK (and £24.13 million to 1188 children in education overseas). (HoC written answer 28 July 2023).
So, the total for CEA payments for children in UK schools for both MoD and FDCO children in UK schools, as provided in written answers to the HoC, is £98.4 million.
If you want to add in the foregone tax and NICs under the CEA policy then HMRC calculates this at around £45 million per year, so that brings the total to £144 million.
Also you didn’t explain your statement the majority of boarders outside of London, are children from military families.
If there are around 51,700 full time boarders outwith London (based on the ISC figures of 66,000 boarding pupils in ISC schools, 2% of these boarders are in London, and overall 80% are full boarders) but the MoD CEA payments only cover 4,210 children and the FDCO payments only cover 514 children, that’s less than 3,000 children?
