Bristol-based I.F.A. Hargreaves Lansdown has launched a guide to SIPPs which explains more about the forthcoming changes to pension regulation and the options that are available to pension investors.
You can arrange to have the guide sent to your home address, or alternatively I would suggest that you go for the download option, as then you can give a false postal and email address, as you have to agree to receive marketing literature from them before you can download the guide.
