Need copy of Income Support Entitlement Letter

just phone them up and they will send you a duplicate letter.

you would have to phone up and make an appointment at the Jobcentre, the contact center staff will then send the section a memo, who will type you a letter of entitlement and then fax one to you at the Jobcentre

they cant send emails, or fax unless it a Jobcentre or secure number
letters of entitlement go out second class post

What will happen is,

You do not always need an appointment at the Jobcentre,

You phone the contact centre and ask that they fax the letter to the local Jobcentre - if they refuse for whatever reason, you could hang up and call again. Eventually you may speak to someone who is happy to fax it to a local jobcentre. However, there may be a perfectly good reason why it cannot be faxed, if this reason is repeated on subsequent calls you know you you are being given the correct advice. ..............
Because the process may involve calling more than once and not least because the letter will be faxed to your jobcentre you might aswell use the jobcentre phones to make the calls because they are free.

Ravenshade,
Whilst what you say makes sense, faxing to the customer's phone that is given on the application form or even subsequently updated. You would not find a staff member who would agree with you. If you wanted to insist on this you would either need to quote the relevant section of DWP guidance which confirms your belief or write a letter to DWP or do a Freedom of Information request to get the answer in writing from the DWP and to be told what to say to a member of staff (i.e. what guidance reference to quote) who is refusing to do this for you. For one thing, the contact centre staff cannot see your application form, they only have computer records.

We would never be allowed to fax out information to anywhere other than a jobcentre. We can fax employer to gather information.
We generally do not accept faxed documents unless the jobcentre has seen the original and faxed it to us as it is impossible to tell on the fax copy if the document has been altered at all.
