According to Webb, as furlough schemes finish and the additional £20 on universal credit payments comes to an end, people who are over 55 and still working might become concerned about their jobs or might find themselves made redundant.
This could put a strain on people's finances, and lead to them dipping into their pension pots under the pensions freedom regime, to help tide themselves over.
Approximately 1.6m people aged 55 to 65 are on benefits, such as universal credit or the employment and support allowance, and this number could rise.
By dipping into their pension they could actually wipe out the help they get with the council tax or even their entire universal credit.Webb
But in a new paper, called 'How getting pension freedoms wrong could cost you your benefit', LCP and fintech company Engage Smarter have warned tapping into the pensions pot could mean tapping out of valuable benefits.
The 26-page paper looked at how the means-tested benefit system for those under pension age and for those over pension age interacts with different pensions freedom choices, such as taking an income through drawdown or taking a lump sum.
The paper said: "The problem facing individuals who have to make these choices is that benefit rules are complex and different pension choices – such as leaving the money where it is, cashing it out in full, going into drawdown or buying an annuity – can have different implications for benefits.
"Some choices may be better than others, but the saver is unlikely to be familiar with the rules and neither is their pension provider. There is a risk that growing numbers of people could make poor choices around accessing their pensions and suffer financial detriment as a result unless something changes."
Of the various options, one of the most dangerous is the temptation to use the pension pot like a bank account.
According to the paper, where people under state pension age take money out of a pension pot, this can affect their benefit entitlement in two main ways.
The first is that, if they end up with more savings, this increases their ‘capital’ when they are assessed for benefit. Therefore, those with more than £16,000 in capital are disqualified from universal credit, while even having £6,000 in capital means help from English local authorities with council tax bills can be stopped.
