Central Exclusive Production (CEP) is a unique process at hadron machines in which particles are produced via colourless propagators, and several measurements at the LHC are directly comparable with past and future electron-ion colliders. LHCb have measured the cross-sections for the CEP of vector mesons, J/ψ,ψ (2S),ϒ(1S), ϒ(2S) and ϒ(3S), which are photo-produced. In the double Pomeron exchange process, preliminary measurements have been made of χc0, χc1, χc2 meson production while the first observations of the CEP of pairs of charmonia, J/ψJ/ψ and J/ψψ (2S), have been made and limits obtained on the pair production of other charmonia.
