  Certainly looks like the young shoots of knotweed. Either way it needs dealing with and that's not a bad spot to be treating it.

    A guy we use to carry out lawn treatments and general spraying seems to think it isn't , but I reckon your right, I'm pretty positive it's Hybrid Knotweed. The clients house is one of a group that was built on land where an older large house was, I reckon the knotweed was there originally, and the developer either failed to remove it properly or simply poured the house foundations over it, it's come up very close to the house but they've never seen it before. What's our best course of action now?

  It looks a lot like the knotweed we had to have treated last year

    Was it successful Rory, I'm looking to recommend a service to the clients, not an area we specialise in but they have asked me to quote the driveway at some point, so we could come up against it, so it would be good to have it dealt with beforehand.

      If you plan to do the drive allow the shoots to develop more! If it is knotweed then any soil excavated will have to be disposed of accordingly. The leaves look to waxy for knotweed.
      
      But the growth rate is about right. And the stems do look very similar.

        There's a lot of panic spread about knotweed. It's rarely a real issue unless you are looking at the massive infestations like you see on the horror-stories about it closing down Cornwall's railway lines.

        Given that picture, and assuming there's not a forest of the plant just outside the shot, I'd dab neat Glyph on the leaves now' and I'd repeat with all new growth. It might take a long time to completely kill the plant, but it will weaken it so it won't spread any further.

        My concern would be that you say you've just finished the job. Are the clients bringing you back in to deal with this as it's not been killed off, or was it something that you weren't aware of? It's something I'd treat as a long-term estimate over at least a few years, or farm off to someone else and walk away.

          I'm just saying that if they are having the drive done then they will need to have any soil removed from around this area disposed of correctly. It doesn't take very much of the root for it to regrow!
          
          Also as a professional we should be taking the necessary steps to ensure we don't knowingly spread an invasive species!
          
          Personally it's better to be safe than sorry!!
