An access cover assembly 1 including a perimeter frame 2 describing an access opening 3 and a cover 4 pivotally mounted to the frame 2. The cover 4 is pivotal between a first orientation in which the cover 4 closes the access opening 3 and a second orientation in which the access opening 3 is uncovered and the cover 4 preferably extends at an obtuse angle of at least 110 degrees relative to the frame 2. Between the first and second orientations is a third orientation in which the cover 4 preferably extends substantially orthogonal to the frame 2. The cover 4 is retained with the frame 2 in the first and second orientations and is removable from the frame 2 in the third orientation. There is also provided a kit of parts for an access cover assembly, a method of disassembling an access cover assembly, and a method of opening an access cover.
