Just messaged the 2 charities to get another letter of autheticity out (as i realised its got my old address on and not the new one)........This letter is used if needed to be produced if collecting donations for say like my auction or raffles etc..........It also proves that you are registered with the charity for fundraising and that they know you are doing it :D 

Also this is a good bit of advice to know if you are fundraising yourselves xx
