When any civil servant puts something down "in writing", they are effectively giving you an official interpretation and judgement on a law that they have no authority to do. That is the job of Parliament and the courts.
Hence, you will never get anything "in writing", by anyone other than a judge or your MP, and even the latter is a bit iffy.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
