15m to Radiators, my question is if I drop a flow and return pipe in
15m to a Radiator in the Hall can the same 15m pipes then go to a
Radiator in my Front room or do I have to install another Flow and
Return pipe from the 22m to that Radiator.

You can just carry on from the hall in 15 mm to the front room.there's
more than enough heat capacity in 15mm pipe to work multiple rads.

My first house was run in 22mm up the middle (centre) of the house from
back boiler then a 15mm f+R came off to do the front rads (4 off) and
another 15mm F+R went the otehr way to do the back of the house (6 rads)
Worked brilliantly.
