Searches for new fermionic states heavier than the top quark are being pursued by the CMS & ATLAS collaborations, pushing the mass bounds towards the TeV scale. Although a chiral fourth generation of quarks is now excluded by the LHC results, models going beyond the Standard Model predict the existence of heavy vector-like top partners as potential smoking gun signatures. Relying on a model-independent parametrisation, we present the first results of a dedicated software called XQCAT (eXtra Quark Combined Analysis Tool), which recasts publicly available experimental data from direct and Supersymmetry inspired searches and computes the exclusion confidence level for New Physics scenarios with one or multiple top partners. The mass limits set on a T singlet scenario with general coupling assumptions are briefly discussed in this framework.
