That isnt the pressure that is a measurement of flow rate

Yes i think its m head.
I would have to get the plumber back to measure the pressures.
One thing worth noting is the flow start off very good and then drops off. I have read this indicates a blockage somewhere. In my case I would have thought the main water line.
I'm not sure how the outside tap has dropped from 12 to 9 /lm. The plumber has possibly put in two extra turns from the main pipe into the house.

You flow isn't just dictated by your pipework. In areas that have typically local low mains dynamic pressure then higher district usage can show up as a noticeable drop in your supply as lower L/min. Different times of days can affect the pressure delivered to your location too and therefore flow.
You need to have the dynamic mains pressure checked at the mains valve, does it deliver what the street is registering at, that way you rule out your system as a contributer. It may be the 3.8 bar at the mains may be a static pressure reading and the mains dynamic delivery might be rubbish, especially if there is a drop off, a mains pump may sort that out but it all needs tested.
TBH though your plumber should know all of this and should already be doing it, he should also really be bending and soldering especially on the mains to maximise flow if there's a flow issue and not flinging pushfit everywhere IMO.
