Over a million SMEs will need to enrol employees into a pension scheme.
The survey, conducted by the Federation of Small Businesses (FSB), discovered that 45% of those asked were confused by the rules.
The Pensions Regulator, however, hit back at the published results, saying the auto enrolment of the scheme was a success.
In addition to those who were unsure about the scheme, 25% of those who were surveyed feared that their companies may not be able to be cope with the costs.
5.4 million workers have been enrolled into the programme since 2012. As a part of this scheme, all employers will need to offer a pension to employees that are over 22 years old and earn more than £10,000 a year.
This includes care workers, plumbers, nannies and bar staff. Businesses will be given a cut-off date to comply with the rules.
An advertising campaign was set up to raise awareness as many didn’t know anything about the rules.
The FSB believes that the campaign was vital in raising awareness. It also welcomed the introduction of better information on the Pensions Regulator’s website.
The FSB’s national chairman, John Allan, said: “Our message for small employers is that auto enrolment is coming and will affect your business – and the sooner you get to grips with what you need to do, the better off you will be.”
The chief executive of the Pensions Regulator, Lesley Titcomb, stated that the auto enrolment scheme had been a resounding success, with over 70,000 small businesses signing up to it.
She told the BBC: “We’re not complacent. In the next three months 100,000 employers have got to enrol their employees. The message to them is that they need to start early and make a plan.”
