A search for Higgs bosons produced via vector boson fusion and decaying into invisible particles using 20.3 fb$^{-1}$ of data recorded by the ATLAS detector at the LHC is presented. For a Higgs boson with a mass of 125 GeV and assuming the Standard Model production cross-section, an upper bound of 0.29 is set on the branching fraction of $H\rightarrow$ invisible at 95% confidence level, where the expected upper limit is 0.35.
