A cleg fly, probably Haematopota pluvialis (a member of the horse flies, family Tabanidae, order Diptera), judging by the good match between the wing patterns in the following photo and that on page 305 of Michael Chinery's Complete British Insects (Collins, 2005).

A plume moth, probably Platyptilia pallidactyla (family Pterophoridae, order Lepidoptera). The similar species Platyptilia ochrodactyla has a slightly different banding pattern on the hind legs.

I first noticed this when a gangly yellow beetle flew across my field of view while I was trying to photograph another insect. Michael Chinery's Complete British Insects identifies it as Strangalia maculata, but two other synonyms, Leptura maculata and Rutpela maculata, seem to be used with equal frequency out on the web. I am not sure which is the currently recommended name. Anyway, it is a longhorn beetle, family Cerambycidae, order Coleoptera.

According to this page at gardensafari.net:
For a long time it was known as Strangalia maculata, but was then placed in the Leptura genus.

A dagger fly (family Empididae, order Diptera), named for the thick proboscis which is used to spear insect prey as well as to suck up nectar from flowers. Possibly Empis livida based on the light coloured thighs and comparison with photos here. Also, it is probably a female based on its thick abdomen. See here for another dagger fly that I photographed in May.
