I have been asked to reply.
National insurance rebates are paid from the National Insurance Fund. The effect on national insurance revenues that would arise from implementing in full the Government Actuary’s advice for rebates from 6 April 2007 is broadly neutral over the longer term for schemes contracted out on a defined contribution basis. For schemes contracted out on a defined benefit basis, it would mean increasing estimated total expenditure on rebates between 2007-08 to 2011-12 by around 9.4 per cent.
