"If I decide to access my pension savings, will my state or housing benefits be affected?"
You should check first by contacting The Pension Service, your local council, or seek guidance from Pension Wise.
If you’re judged to have deliberately spent or given away your pension savings to receive or increase benefits, the Department for Work and Pensions or your local council may re-assess your eligibility and treat you as still having the money. If you’re able to take an income and have chosen not to do so, some or all of the income you could have taken may be taken into account.
