Could this plant cause problems?

Hi
Can anyone identify the plant in the photographs please? It is growing on an area that will become our garden in a new house. It seems to have grown very quickly. Could it be an invasive knotweed? Could it be problematic?

I think it is a persicaria, a knot weed but not obviously the dreaded Japanese one.

I would not want much of that in my garden though. That is a flipping field full.

This is what I meant to show. Flipping edit function failed me.

Thank you lamweedy
There is a lot of it! The developer will put turf down over that area but worried about it returning. It also borders a woodland area so could be difficult to get rid of?
It's a Persicaria. I can't see it clearly but it looks like the one which is a common weed on agricultural land. It shouldn't be a problem if sprayed with a glyphosate weed killer and allowed to die off before cultivating the land.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Agreed, it's a weedy type though - Pale persicaria I think:

Thank you everyone. It looks a lot like the photographs of the pale persicaria. That has put our minds at ease

I've just bought a new build house and most of the gardens of the houses that haven't sold yet are full of the same stuff. It was a field before building started. I had weeds growing in my garden that I've never seen before, really strong. I used a weed killer that contained glyphosate and it did the job very well. After a couple of weeks we had it rotovated and the soil improved and a seeded lawn put down.
It went from this
To this in 5 weeks!
Im so glad we decided to go with seed rather than turf.
Brightstar My worry would be that depending on how strong the really bad weeds are just one dose of Weed Killer might not be enough to finish them off and rotovating could just chop newly emerging weed shoots into smaller and smaller pieces and spread them.
Keep your eye on it for a while. Do you have any idea what weeds were there.
We had lots of Dock weeds coming up through our newly turfed lawn for years.

We dug up some of the weeds that looked particularly strong before we sprayed with weed killer and I gave everywhere a thorough spray. I used Roundup. The grass is getting cut twice a week at the moment and we are checking for signs of weed regrowth, we are getting the odd bit of chickweed, nettles and buttercup on the edges but nothing on the main lawn as yet. The gardener did put a lot of seed on, and half of it was buried so I'm hoping that the grass will crowd any weeds out
