Not a good shot for ID purposes but only managed one shot of this wasp. About 7mm body length. Taken Yesterday South Coast UK.

Thanks Brian V.

My coleague, working with hymenopterans told it looks like Pteromalidae.

"In essence, a "Pteromalid" is any member of the Chalcidoidea that has 5-segmented tarsi and does not have the defining features of any of the remaining families with 5-segmented tarsi. " An artificial family easy to define except by differentiation*.This doesn't look like anything else so Pteromalidae it is. *See differential in Glossary ;)(opposite diagnostic)

Torymidae? Not sure how many tarsi they have without pulling one from my collection, but they have that general appearance.

Torymidae also have 5 tarsal segments but is the ovipositor (often) much longer than the body at 7mm. total length. No mention of this feature either.

Thanks for the ID so far :)
Not sure if it helps but one other shot of it was not as bad as I thought- at least you can just see the abdomen which is tapered but no ovipositor visible
