If you're eligible, you'll be contacted by DWP (Department for Work and Pensions) with details of what they need from you (if anything). In most circumstances, you will not have to apply for the rebate - if you are eligible, £80 will be applied automatically to your bill, or if you use a prepayment meter we will send the rebate to you via Post Office vouchers.
If you would like to check to see if you qualify, you can call the DWP helpline on 0845 600 0033, or our own specialist team on 0800 980 5525. For generic info about the scheme, just click on www.dwp.gov.uk/newsroom/press-releases/2010/march-2010/dwp044-10-120310.shtml
