It's not an unreasonable statement to expect that no-one would want to turn down 'free' money.

Many may question what the catch is? But in this instance there really is no catch.

Many employers offering defined contribution pensions will provide employer contributions above the minimum required by auto-enrolment - in some cases employer contributions may be 7%-20% - so a significant monthly contribution to their employees' pensions.

However, to get this maximum employer contribution, employees may be asked to contribute to a level themselves, in most cases likely to be above the auto-enrolment minimum. 

But this minimum employee contribution level may not be that much more and may be entirely within the reach of many employees, say 5% - 7% employee contribution to obtain 10%-20% employer contribution. By all reckoning that sounds like a fantastic deal for the employees concerned.

But this research from Royal London suggests that there are many employees who are foregoing that maximum employer contribution as their employee contribution is too little.

With the bonus of tax relief and some focus on small changes to reduce outgoings, getting employee contributions up to the level that drives maximum contributions from their employer should be possible for many people.

Where else would you get such beneficial investment terms? Very few places for the same level of risk.

Pension engagement exercises can help all employees to see the significance of both the employer contribution and tax relief on helping them to build their pension pot. Such exercises should help every employee to see how quite small changes to their budget may take them to that maximum employer contribution level and the huge benefit this will make to their pension savings plans.
