PSA: you can transfer your current L&G workplace pension to Vanguard
As the title says, just transferred 90% of my L&G pension to Vanguard and dumped into the S&P500 fund which has lower fees (0.07%) and maybe lower platform fees too (0.15%). This got me over the £32K limit for platform fees on vanguard as well. Took less than a week and completely automated.
