The government is looking http://www.bbc.co.uk/news/uk-11657006 at copying a Japanese scheme that a allows volunteer to "bank" the hours they spend helping an elderly or disabled person in their personal Time Account ... These healthcare credits are guaranteed to be available to the volunteers themselves later in life, or to someone else in need, within or outside their family.

This allows the government to borrow without using the financial markets so presumable avoid adding to the National Debt, but at the end of the day these credits will still have to be paid back (or defaulted on) so are still national debt.
