I had a couple of pension schemes with Equitable Life before it went belly up. I didn't lose too much compared to others, and moved over to Standard Life. A few years ago, I went to see a firm of pensions experts. After two hours, my head was reeling but I gathered that they wanted me to embark on a brilliantly clever "vehicle" with them. A few days later, a 40mm thick document dropped through the letter box.
I totted up all the set-up costs and the various management fees. For the next decade, 30p in every pound that I thought might be going into my pension pot would actually be going straight into the experts' wallets. It wasn't a very attractive scenario.
BTW, my smart friends bought property somewhere.
