We investigate non-Abelian gauge theories within a Wilsonian Renormalisation Group approach. The cut-off t.erm inherent in this approach leads to a modified Ward identity (mW1). It is shown that this mWI is compatible with the Bow and that the full effective action satisfies the usual Ward identity
