This is a very close relative of Juncus bufonius (Toad Rush) but far less common. It is characterised by having fewer flowers which are bunched together at the tip and the inner tepals having a slight point (mucronate) at the tip which you can just about make out in one or two of the flowers. The whole plant is more compact, smaller and more prostrate than Juncus bufonius but there are more similarities than differences so even when you're sure about the identification there is always a slight lingering doubt.

J. ambiguus tends to prefer coastal habitats and is scattered on coastal sites throughout the British Isles.
