A wind turbine rotor blade lightning receptor arrangement (12) is provided with an electrically conductive block (123) and a shielding component (122). In use, the electrically conductive block (123) forms an electrical bridge between a receptor element (121) of a lightning protection system and a down conductor (15) of the lightning protection system. The electrically conductive block (123) comprises a first engagement surface (124) for, in use, receiving the receptor element (121). The shielding component (122) overlays a portion of the first engagement surface (124) of the electrically conductive block (123), while leaving open an area for receiving the receptor element (121).
