We investigate the variation in the MMHT2014 PDFs when we allow the heavy-quark masses m(c) and m(b) to vary away from their default values. We make PDF sets available in steps of Delta m(c) = 0.05 GeV and Delta m(b) = 0.25 GeV, and present the variation in the PDFs and in the predictions. We examine the comparison to the HERA data on charm and beauty structure functions and note that in each case the heavy-quark data, and the inclusive data, have a slight preference for lower masses than our default values. We provide PDF sets with three and four active quark flavours, as well as the standard value of five flavours. We use the pole mass definition of the quark masses, as in the default MMHT2014 analysis, but briefly comment on the (MS) over bar definition.
