Reality is though, if you have a pension pot, no matter how small, your best yield will always come from seeing it throguh to the point of maturity, an early cash in value is always poor (and that includes transfer values)
Huh? You cannot cash in a private pension - and never could. You must be (at least) 55 years old which is set to rise to 57 in the future. There are some scams that claim to liberate your pension, but these are all rip-offs, and you will lose the lot. And a pension isn't an endowment - there is no such thing as maturity - you cannot surrender it early, or use it as security on a loan/mortgage etc.
On cash in I am referring to transfer/movement from plan to plan and not a take a wedge of cash and spend it. 
But is still makes no sense. There are a few legacy products which have what are called "Garanteed Annuity Rates". Assuming your pension is NOT in one of these, then the transfer value is simply the market value of the assets you currently hold. Valuing a legacy "With Profits" fund can be difficult, but a modern SIPP/Stakeholder/PP is almost always just the value of all the assets you hold.
You can use your "pot" of money to buy virtually anything inside the pension "wrapper". Transferring is simply selling what you currently hold for whatever it's current market value is, and buying something else instead. So for instance you could sell your current Vodaphone shares and buy Shell shares. Transferring from one provider to another is a lot easier than it used to be, although there will be costs because the assets have to be re-registered to the new provider. The providers now have to tell you what their charges are, and provide you a yearly statement. If you think you can get lower charges elsewhere, then transfer. Yearly fees are typically 1% ish, but you can get that down to less than 0.5% with some products.
I don't see how it could be much simpler? And as of the last budget (once the legislation goes through parliament) you can take
all of your pension pot as a lump sum the minute you turn 55 (although 75% of it will be taxed). No requirement to buy an annuity or anythig else - you are free to pi55 it all up the wall if you want.
