John Cridland, CBI Director-General, said:
"The Budget will put wind in the sails of business investment, especially for manufacturers.
"This was a make or break budget coming at a critical time in the recovery and the Chancellor has focussed his firepower on areas that have the potential to lock in growth.
"The CBI has pushed hard for this significant and much-needed energy package that will help keep manufacturing jobs in the UK, while underpinning vital investment in new energy.
"The doubling and extension of the Annual Investment Allowance, together with making the seed enterprise investment scheme permanent, will be a shot in the arm for many medium-sized businesses.
"On pensions, what's important is that people on low incomes can make more informed decisions on defined contribution schemes. For many, that will still mean taking advice and buying an annuity, but the increased flexibility will be welcomed.
"We are pleased that the Government has chosen to consult on the implications of making a similar change to defined benefit pensions as stability for these schemes is essential.
"Changes to the ISA system reflect our call to help rebuild a savings culture."
