I mean the wee white plant in the middle , we didn't plant it as far as we remember

It could be Silene Nutans, Nottingham Catchfly.

We are in Northern Ireland , Silene seems not to grow here ? Just taken another snap

They still look like a type of Silene to me. There are quite a few types.

arneil

thank you , I'll tell the boss

Flower form is right for Silene.  How about Silene latifolia (White Campion)?

Sorry but Silene latifolia has wider white petals...see pics 1 and 2.below

arneil note how your petals are very thin and fine.
Might it be Lychnis flos cuculi "White Robin"...the white form of Ragged Robin?
See pics 3 and 4 below.

Both the Silene and Lychnis are found in Ireland.

Silene flos-cuculi is the old name...now called Lychnis flos cuculi

Should have ruled out Silene nutans...it has 5 petals split into 2...so it appears to have 10 thin petals.
Silene latifolia has 5 petals split into 2 so it appears to have 10 wide petals.
Whilst your flower has 5 petals split into 4 .

Maybe this will help.
