Service update in light of the Covid-19 (coronavirus) outbreak

Given the unprecedented circumstances we’re all facing in light of the Covid-19 (coronavirus) outbreak, our service is currently being impacted in the following ways:

  • Our phones lines are open, but with limited availability, between 12pm and 3pm. Please only call us if you are facing severe ill-health or financial hardship.
  • We are not currently able to receive post at our office. Please do not send us anything by post. It is very likely that any post sent to us after 18 March 2020 may not reach us.  As Royal Mail are unable to deliver post to our office, they’ve told us that they will hold it for 28 days. If after 28 days our office remains closed and we haven’t been able to collect our post from Royal Mail, they will look to return it to the sender. If you’ve sent us a complaint form by post, please resubmit this either by email or using our online form. 
  • It will take us longer than we’d like to resolve complaints.

Our staff are working hard to continue to provide a service to the people who need us.

If your complaint has been allocated and you have the contact details of the case handler, you can contact them directly.

Alternatively, you can contact us in the following ways:
