Liaison: External Links - DWP - Requesting Information from DWP
Now we have access to ADD there is no longer any need to contact DWP as there is little additional information that DWP could disclose to us that is not already available on ADD. If you need to check DWP information or data you should access ADD.
If the information you need is not on ADD you should write to the customer as normal and if you do not receive a reply to your request for information you should return to the guidance you were following to take the correct action.
If your letter is returned RLS, or if the customer’s address is already marked RLS, then you must follow the RLS action in the guidance.
