The Pensions Advisory Service (TPAS) is launching the helpline - 0845 602 7021 - because of the shortfall in pension provision among sole traders and other small enterprises.

More than half of self-employed women don't have a private pension, according to the Office for National Statistics (ONS). Business owners are also eligible for less from the state when they retire.

TPAS's Malcolm McLean said:

"We are well aware of the disadvantages the self-employed and small business owners face in getting advice on pensions.

"I believe our new helpline will fulfil a real need for this important sector of the working population."
