It’s less about the pension company and more about the funds they are investing your money in. When I was at work we used to have an annual review with a pension advisor who explained what funds L&G in your case, invest in and which ones we could move our money in and out of. Eg Property, cash, global funds etc. depending on the performance of the stock market and our own risk profile.
Even if you have little choice as to what your money is invested in someone somewhere should be giving you more information and an annual review. Talk to HR.
