HM Revenue & Customs say "Pension liberation is on the increase with promoters using increasingly more sophisticated liberation models to encourage taxpayers to put their hard-earned pension savings at risk through liberation. 

Over the last year HMRC has formed part of a multi agency government task force working closely to warn individuals about the consequences of pension liberation and to address growing industry concern."

HM Revenue & Customs have published a factsheet designed to help explain the tax consequences of pension liberation to individuals. You can access this here:
