Check that the insulation isn't blocking any vents, it should be clear of the soffits.
 
Check the small header tank in loft that the boiler is not pumping over and the tank getting full of hot steaming water.

If ok you may just need a couple of vent tiles fitted
 
lack of ventilation,extractor venting into loft,drying a lot of washing on rads / tumble dryer not ducted

Yep lack of ventilation, loft insulation company's should now fit extra vent if required free of charge
