The Pensions Regulator has revised its estimate of the number of small and micro employers who will need to stage between now and 2018.
TPR figures show that a total of around 1.8 million small and micro employers will stage over the next three years, compared to the previous estimate of 1.3 million.
TPR said that the reason for the revision of the estimate was that more business start-ups had entered the UK market, and that there were lower numbers of business closures than anticipated.
However it should be noted that a large number of micro employers will be one director companies where the director is also the sole employee. These employers are effectively exempt from auto enrolment and can "opt out" by informing TPR.
