Seems that they are in a flat spin trying to stop the idea that there will be no charge to supply a record.
Appeared in the last week or so on the page
https://www.gov.uk/get-copy-military-service-records/apply-for-someone-elses-records"When you apply online for a British Army or Home Guard record, the MOD will check if they hold it. If they have it, you’ll be sent a link to pay. If they do not, you’ll be told to check The National Archives."
It is to prevent bad press from the old system as more records become available at the TNA eg MoD charged me £30 upfront - not refundable - to tell me I had to pay again at the TNA
So now you apply to mod they send you an payment screen or tell you where the record is.
The more interesting bit is the one for WWI records.
If you follow the link to the TNA page it describes how to do an FOI to get possible access to the Closed responses that started this thread.
I suspected that TNA was not doing an individual FOI review even when given a proof of death - this confirms that you got the stock answer Closed until - but it was not made clear until now that you needed to do a specific method of request to trigger the review.
Note as well that it covers those with a date of birth up to and including 1939 not just WWI as per MoD page.
