A tile laying accessory includes a flange having opposed ends and opposed sides, a web that extends from the flange, intermediate the opposed sides, and at least one spacing formation arranged on at least one of the flange and the web. The flange and the web are configured so that edge portions of two adjacent tiles are positioned on the flange on respective sides of the web, with the web extending between the adjacent tiles. The web is configured to engage a levelling member having a bearing surface. The levelling member and the web provide relative displacement of the levelling member and the web, which results in the bearing surface of the levelling member bearing against the edge portions of adjacent tiles. The spacing formation is configured so that the adjacent tile edge portions bear against the spacing formation with the web being spaced from the adjacent tile edge portions.
