Depends what you mean by indie. The sound or the label? Taking both into account, I'll plump for Elastica (Deceptive were a pure indie label, right?).
Yes, Deceptive was an indie
The label was set up by Radio 1 DJ Steve Lamacq and records were distributed by Vital, an independent distributor (now part of PIAS, whose distribution warehouse got torched during the idiotic London riots in 2011).
