Not another warm home discount thread...

I received a text from Eon Next yesterday suggesting that I could be eligible for their WHD scheme. (Possibly different to the gov't one?). The text looked genuine, same as previous texts from them, and even had my account number on it.
Is this genuine or it a scam? I can't find anything about it on here or on the Eon website, and I usually receive emails from them rather than texts.
It linked directly to a survey website, which asked for my address, so I just closed it down at that point. Just interested to know whether it's genuine or not really. I can't be the only one to have received it.
Thanks
