The high-precision HERA data are used to search for Beyond the Standard Model contributions to electron-quark scattering in the framework of eeqq contact interactions (CI). Combined measurements of the inclusive deep inelastic cross sections in neutral and charged current $ep$ scattering are considered, corresponding to a luminosity of around 1 fb$^{-1}$. The analysis of the inclusive $ep$ data is based on the simultaneous fits of parton distribution functions together with contributions of CI couplings to $ep$ scattering. Results are presented for different CI scenarios and the resulting 95% CL limits on the CI mass scales extend up to the 10 TeV scale.
