USS pension halal?

Salam all,

I have started a new job and wondering if someone can help with a pension question, please. I am quite new to pensions and unsure if my workplace pension is halal.

It’s the USS Pension https://www.uss.co.uk. It has two parts, the defined benefit pension and an investment contribution pension - this is where I have control over where the money is invested (but not in the defined benefit part of it). I believe there is a USS Shariah complaint fund - does anyone know if this is halal to invest in please?

Thank you,

Sunnah
