Sooooo, 10 ltrs took approx 30-40 sec on feed and return so that sounds pretty good. While about it i replaced isolator with full bore valves anyway. Let 20 ltrs flow through drain valve for feed and then flow with TRV locked on the other rads. So should be no air trapped ive got good flow on return and feed independently

Results are in. Heating engineer has checked the boiler, somehow the flow vale had been knocked and was almost off. Reset to correct position so now working fine.
Thanks for help, there was some really sound advice which really helped.

So I was right about the isolators... Just not the right ones!
