Not the Norwegian Blue, then?

Yes they are Mallards. Mallards have been domesticated for so long that there is a wide variety of colour forms and shapes and sizes to have come out of that process. Random white patches are regular in domesticated birds. It could be a  "Swedish Blue Duck" or some other variety of Mallard, via a long domestic history of a range of selective processes. Certainly not Blue-billed Ducks, apart from what Denis wrote, they are far too big.

Re Lucy's mystery ducks, I must beg to differ from John Layton's suggestion. Blue-billed Duck have a very different shape on the water. They sit low on the water, and have rounded backs, and do not have a white throat.

I cannot offer any suggestions for an ID, other than to agree with Lucy's suggestion that they are probably escapees.

 

A quick image search on "Domesticated Ducks" revealed many large ducks with white throats. One such variety is called "Swedish Blue Duck"

Hope this is helpful.

They are considerably larger than the resident wood and black ducks. I don't think they are and assume that they are escapees.
