Hi

In our newly-laid (around January) lawn, there is a hole, (very)
roughly 3mm across, with earth piled around it. It appeared last
week, when the weather was somewhat kinder than it is now; we have
also seen some similar ones on verges etc around here. It puts me
in
mind of ant holes between paving slabs etc, but is much larger. Any
ideas?

All sorts of 'solitary' wasps (and other insects) dig holes in the
soil. They can be(e) pretty slim in girth.
And they are not necessarily dangerous either.

Might be a solitary Bee as well. Calling them wasps gives some people the
wrong idea, don't know why.

We have lots of these holes in the lawn, no big deal in my case it's not a
bowling green, we've also got mortar bees living in the roof, again so what,
maybe in about 20 or 30 years they could cause a problem, but if the roof
lasts that long without being looked at then great.

Sorry preaching again, must stop it.
