1&2 from the boiler to C&NO for standard control , if you want to use open therm control (recommended) its 44 and 41 from the boiler to OT1 and OT2 at the nest E, if you want to use the open therm you will have to go into the installer menu and :

Refer to parameter P7 (see Section 5.13) to select the correct parameter to allow the boiler to operate with alternative control type '1'.
 
Cheers ian thats great ill have a go laterzz where you said 1&2 to c&no does that matter which way around and or do i disregard that if i take the open therm option

nope with both options it doesnt matter which way round you wire them, but you have to wire them the way I advised, you cant wire the OT to the standard settings
