The 'Animal Nitrate' singer reformed the group in 2010, seven years after disbanding it, and although he has loved playing numerous live dates since the reunion he doesn't think there is any artistic merit in continuing unless they record a new LP.
He said: "I don't know what the future for Suede is to be honest. I'd like to think there is a future for the band but I think realistically unless we make a new album I don't see that there's much future in just going around playing the same set from the 90s year after year. I'm not sure I want to do that with my life. It's really important to look back sometimes, as well as look forward, but I love making new music, I've just made a new solo album and that's what I'm going to be doing next. We're going to try to make a new Suede album but if the magic is not there then no one will hear it, that's the truth. I don't want to just put a record out just because people want us to. If it's not right, it's not right."
Despite his musings on the band's future, Brett has loved being back in Suede.
And the 43-year-old singer believes the reunion has been such a success because when the group broke-up - shortly after the release and disappointing reaction to their fifth studio album 'A New Morning' - they were at a "low point" and had something to prove when they returned.
He added to BBC Radio 6: "I think the reason it has worked for Suede, if I analyse it, is because when we left the stage in 2003 we left on a low point and I think one of the main reasons why the reunion has worked is because I think it's been about redressing that balance.
"If you leave on a high point I think it's kind of harder to have a reunion that works really well, when Suede split up it was our weakest album and a lot of people that might have cared about the band splitting, didn't care about it splitting. So when you reform people are reminded, 'Oh actually, they were pretty good.' "
