If you don,t need the funds now ,maybe do as follows. ?
Let it sit, as you suggest , until you must take it ie 65.
Even if you could encash the lot today as per uk ,you would be hit hard by Tax ,not sure if the uk system, other than for small sums is a great idea.
Probably will grow a bit + since 4 years older might get more than the 90 + we could have future possible positive changes to encashment rules.
You can then review.
ps . 90 a month is small but if all you had @66 was old age pension , that 90 a month would be a very welcome ongoing boost..
