That the government will guarantee that the GP's will not charge for a letter.

Because the government has said there will not pursue the vaccine passport for travel but if for example the other contries ask for a letter from our Gp's we will not fund any cost to us but the government will bear the cost of letters to travel now and in the future

We can't accept your petition because the UK Government and Parliament aren't responsible for the issue you raise. The Government aren't responsible for GP charges such as letters.

You could start a petition calling for the provision of free proof of vaccination certificates, or you might like to sign this petition:
