The cross-section for central exclusive production of J/psi and Psi(2S) mesons at 13 TeV is measured using the LHCb detector. Proton dissociative backgrounds are significant reduced compared to previous measurements through the use of forward shower counters, recently installed for Run 2. Cross-section ratios to previous measurements at 7 TeV allow more precise tests of theoretical predictions and constraints on the parton distribution functions
