1. An atomizer for an electronic vapor provision system, comprising a heater for vaporizing aerosolizable substrate material and a portion of porous material for wicking aerosolizable substrate material to the heater, the heater having an elongate format and formed from a planar element of electrically resistive material having a length, a width, and two pairs of opposite edges comprising two major edges substantially parallel to the length and two minor edges substantially parallel to the width, wherein the planar element is curved to form the elongate format of the heater such that the edges of one of the pairs of opposite edges are located adjacent one another and the curved planar element defines a volume, the portion of porous material accommodated in the volume,
wherein the planar element is curved around an axis substantially parallel to the length such that the two major edges are located adjacent one another to form a heater with a substantially tubular format, and
wherein the planar element additionally comprises an end portion, the end portion extending from one of said minor edges, and folded with respect to that minor edge to at least partially cover an end of the tubular format of the heater.
