warm home discount scheme

Hi I've tried phoning EON on this but they couldn't help.

Please could you tell me if I can claim Warm Home Discount for my adult daughter who lives with us and is on ESA Support Group and DLA LRM & LRC.

So far I've only found forms that ask if its myself or my husband that qualifies, neither of us do, but it costs a lot to keep the place warm for her.

Also is this something just for Electric?

Thanks
