We have had a new combi boiler fitted in a different place they have connected the 22mm flow and return from the boiler for the heating into a 15mm pipe which feeds a radiator and not to the 22mm pipes that run down the house with 15mm branches off to the other radiators. Is this Ok or will it not work as well as it should ?

Yeehah, how many rads have you got? Can we have some pics?
+1 Can I hear the theme from The Good The Bad And The Ugly playing in the background? 
Supposing that the original installer of the heating system specified that 22mm pipes were required, then usually these should be connected to the boiler flow and return connections in 22mm all the way.
How do your rads heat up?

put it this way, 15mm pipe can carry up to 5kws, 22mm can carry 20kws or so...

If your drawing is correct then i find it incredible that they could plumb in a boiler that way on a system with 8 rads
