Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
Can you post a photo of the very top of the boiler where the flow & return pipes are or/and ask you plumber to ensure that the flow pipe is connected to the pump inlet.
Edit: As per post#14.

This is how it should be piped it's obvious that the existing pipe has been adapted and only minor alterations made it not the best job in all honesty , we need to know where the vent and cold feed are connected ? If it's on the live side of the pump ? It could cause issues ? Kop

My water tank is in the loft - is that what you mean by cold feed connections? (apologies im not very knowledgeable in this)
Vent is on the side of the house, sticking out from the wall.
No the heating system cold feed and vent connected into the system pipework?? As the picture below

Will do, sorry I didn’t thought of it. He is coming today at 4 to start, I got all the previous messages ready. He installed it on 10th March so it’s been a while and I really hope with all this help here he will be able to fix it.
Is there only one tank in the loft?? or are there two, one much larger than the other??.
It looks like you may have a sealed system and a system boiler, not a heat only boiler, which I think refers to a vented system, you should see a red tank somewhere, probably near the boiler that may have a pressure gauge on it or the boiler may show a indication of pressure like 1bar to 1.5bar or similar?.
Should definitely be Heat only as I specifically wanted like for like change, please see a few pics with boiler details. Plumber would have noticed that’s it was s y stem one I hope, I’m doubting everything now 🙁

The attic Tank may be your F&E tank for the boiler/system and you may have a unvented HW cylinder fed with mains cold water, if the hot water pressure/flow is the same as the cold water kitchen tap then probablay a unvented or look at the label on it, it should show the pressure.
Plumber did mentioned that he can install something for pressure but it can only be in the loft where water tank is so he said its not a good idea as i will have to go up there to change pressure. I'm sorry im so confused now with what i have and what it should be. All of you guys are amazing in writing all this details without even being there, it makes more worried that my guy been coming for 20 days now. He said today that he will maybe change the pump to UPS2 instead as its much more forgiving with old pipe system.
He most certainly does not have to change the UPS3 because its too powerful, one can get any head required as shown above by changing its mode and setting. Its presently on speed 2 which is equivalent to a 5M pump, the head can be still further reduced in this mode to setting 1 which makes it a 4.2M pump, you can further reduce it to a 3M pump, CP1, or still further to PP1 which is only a 2M pump that isnt even powerful enough to circulate the water through your system. The UPS3 is only too powerful if the wrong modes and settings are selected.
Attaching pictures for under the boiler, water cylinder connection and top of the boiler.

Has he not fixed it today then? There should be an arrow on the circulating pump, can you see it? There’s a 22mm pipe that comes across your boiler and runs on the left hand side, is that connected to the hot water?
He canceled today, coming tomorrow at 9.
I found an arrow, it’s pointing downwards. The pipe, sorry, is it the one on the picture? It’s going down parallel water cylinder, but I can’t see where it’s connected.
