Dung

"It has a very long season and adults can be found at any time of year
including mid-Winter (Blackith & Blackith, 1990). Although it is most
abundant in farmland were cattle are to be found, specimens can be found in
any habitat from city centres (where it can breed in dog dung - Disney,
1973) to the tops of mountains (I have found specimens, with S. furcata, on
reindeer dung near the top of Cairngorm). Females particularly disperse
from breeding areas into hedgerows and woods where they are voracious
predators on other flies and there is quite extensive literature on their prey
selection. Both sexes are often found visiting flowers, such as umbels of
hogweed (Heracleum spondili) where they both feed from the flower and
hunt other insects which the flower attracts."

That is taken from Stuart Ball's Key to the family. The fact is that dung, whether human, sheep, horse, reindeer or whatever is found pretty much everywhere through the UK, so it's a species you can just find anywhere.
