The figures are taken from a survey of more than 300 employers carried out by Hargreaves Lansdown.
Hargreaves Lansdown head of corporate research Laith Khalaf told HR magazine the findings show that employers are "seriously underestimating the impact of recent changes".
"The reforms are far-reaching: pension freedom for employees, a charge cap on default funds, and the ban on commission payments to advisers," he said. "Almost every company pension scheme in the land will be affected and will have to make some changes to accommodate these new rules."
Khalaf added that the legislation is likely to cause "profound" changes in employee behaviour, something employers will have to be prepared for.
"The problem is many are just drawing breath after the exertion of auto-enrolment and were probably not expecting to have to make changes to their scheme quite so soon," he said.
North South divide
Employees are facing a 'postcode lottery' regarding the amount their companies contribute to their pension pots, according to research by NOW: Pensions.
A survey of 450 SMEs suggests only 5% of firms in the north intend to contribute more than the minimum to their staff's pension pots, compared to 11% in the south. Of the companies in the midlands, 6% say they plan to pay more than the minimum contribution level.
NOW: Pensions CEO Morten Nilsson told HR magazine that while the vast majority of employers are focusing on compliance, many are ignoring the power of enhanced contributions in engagement.
"Just a 1% increase in contributions can improve an employee's pension pot, based on average wages, by 12% by the time they retire. This equates to more than £50,000," he said. "After holidays, pensions are the benefit that employees value the most, so they can be very powerful for engagement and attraction."
