amaurobius simlis
Took a risk on the ID and opted for A. similis over A.fenestralis owing to it's location, which is on my wall. The latter not usually being associated with gardens and buildings. It's a shame it had it's head stuck in a hole, perhaps it will emerge after dark.

''Amaurobius similis'' is a species of spider in the family Amaurobiidae. It is one of at least two common spiders found in houses known as lace-webbed spider. The specific name ''similis'' is based on its similarity to the species ''Amaurobius fenestralis''. Both are often found near windows, hence the specific name of ''A. fenestralis''.
