yes and being fed via the tanks so its boosted upto what every you set the pumps at then reduced down at the control block

sorry thought your tanks were in Litres
should be enough but depends on your mains flow rate dynamic
also the control block he should know what this is and its already fitted
tbh you shouldnt have to pay anything as its his mistake not checking things first and good enough
Whilst I agree with you, I don’t know of any trades person that I’ve come across yet that would swallow that much material and labour (relative to be size of the job). He’s already been paid for the job so I can’t even challenge him with payment. He did agree to charge me minimum labour for this change though. Getting someone new in would also cost me and then there’s finding someone willing enough with the knowledge.
If you’re able to clarify about the use of the shower pump I think this should be enough info to go back to him with? Hopefully I can use one of my existing pumps if I can.
Am I right in understanding that with the setup you’ve proposed, the pressure at the showers would now just be at whatever the output of the chosen pump is? I was very happy with the previous setup and the output at the showers which came straight from the pump (just wondered if I’d still need the shower pumps with your set up)
He’s now booked the job in for Monday as he he didn’t want to commit to 1 day on Thursday and I can’t do Friday or this weekend.

I guess also what I'm trying to understand is, what is the difference between a shower pump and the pumps you've recommended.

OK. So i've spoken with the plumber.
@ShaunCorbs he agrees that your set up whilst better and ideal, unfortunatly won't work in my situation, as apparenty it means more piping configuration changes and breaking a wall and some ceilings (as I have the 1st floor loft where there current cylinder is, and the 2nd floor loft where the water tanks would be). Now there is no way i'm going to start ripping things open and doing all of that, as he said he could do it, but the additional labour and hardware costs would be substantially more. And the house has just been finished and decorated. Again, i'm just taking his word on this.
He became slightly frustrated and said that he could easily walk away from the job, but he's confident that the pressure and flow rates were adequate at the mains before he took on the job and he will show me. He's said he's fairly certain that my water softer is responsible for much of the drop in flow/pressure too but we will test this next week. He said if the flow rate was more than 15L at the mains, then it's just a case of me not being happy as I was used to the previous shower pump set up.
I asked about pumping out of an unvented cylinder - he said that effectivly the new unvented cylinder would become vented so this wouldnt be a problem. So I dont think I have any choice but to go with his proposed solution.
On another note, if the tank is no longer 'unvented', would it still need the annual servicing? I've just signed up to an annal service plan with kingspan for the warranty purposes, so would this be a waste of money? They are supposed to be coming on friday to inspect in insulation. Do you think it's worth postponing this until AFTER he has done all the changes or just cancel it all together?
