Renewing tax credit by post

Hi guys,

I sent my forms off by post on the 3rd of June. By now in previous years my payments would have normally changed slightly. However, I've again today had my usual amount. I know we earnt £4000 less this year that last year so I am expecting my payments to increase slightly.

Has anyone else renewed by post and if so how long did they take to make different payments or send you a tax credit award? I renewed by post because most people phone, so thought it may be quicker this way.

Thanks in advance
Charlie
