New Worcester 34cdi classic. Hot water ok, Flow hot, return cold, all rads cold

[Neilly]

Have new boiler installed. Central heating and hot water all working before replacement. Flush etc all carried out before replacement. Hot water heats perfectly but no radiators heat and no heat in flow to any radiator. Tried crossing flow and return but no joy. Doesn't seem to be a block in the pipes as checked section where heat is lost. Suspect boiler issue - any thoughts?

New install?
Why not get the installer back. If it's a boiler problem, it will be under warranty. If it's been registered by a gas safe engineer?

Doesnt matter who fitted it, its Worcester that'll come out to check it under the warranty.
