Did Howdens design this? Hopefully it's not their best effort. I don't think it has great "flow" although the white units do look very fresh and clean.
The dishwasher and fridge are both in a corner, in fact their doors might clash which will be annoying.
Also I would not put a tall unit between the hob and the sink.
In that room I think I'd go for a more usual L shape with (from the left) dishwasher -sink (drainer the other way)- prep space - hob - tall unit on the end of the run near the door. On the wall opposite the hob, have a tall fridge freezer and larder cupboard. If you really want the peninsula, the only place for a high oven is on the wall opposite, but then people coming into the room will be going right past the oven behind the door, which might not be very safe.
Honestly in rooms with many doors it's nice to just be able to walk across and not be obstructed by a peninsula. If you have a dining table with generous, comfortable chairs, people will sit there and chat to you rather than perching on bar stools.
