Here’s some more pics!

Ok so fairly small system I’d say potentially not a balancing problem. By turning off all the other rads except the not working ones can you get them to heat up

 

[Riley]

Could you take one just stood back with the door open

 

[Mandy Cowlishaw]

I’ll try turning the others off now

 

[Mandy Cowlishaw]

Here you go!

The pipes leading to the rads are really hot but the rads are still just warm at the moment.....

Agree with above, perhaps turn off all upstairs and see if downstairs heat up and then vica verca then continue to open one at a time and see if they can all heat up if not all simultaneously. Although debris can shift you're tying to establish whether it's the pump, crud in the system or both.

Are the TRV's (radiator thermostats) on max?

 

[Mandy Cowlishaw]

Yes the two rads not fully working are on the maximum setting but still no change in regards to heat

We’re just trying to make sure 2 rads upstairs are off because one of them was on even though the TRV was in the off position.
The other one in the bathroom does not have a TRV
