I 'invested' 100k with Guardian Wealth Management 4 years ago whilst in Qatar, and just got 101k back. Circa 0.25% PA. As far as I'm concerned it's a good result as I've got my initial investment back. Nowhere near my objective of keeping pace with inflation. It's been painful watching our money 'flatline' for the last 4 years with no attempt by Guardian to manage our money. From what I can see of it they are nothing more than salemen. They promise to 'actively manage' funds via their iguard protection, but what they actually do is simply dump our funds into a policy and then collect their charges. To add insult to injury it cost me over 3k to surrender the policy a year early. I don't know if anyone else has experience of them, but I strongly recommend giving them a wide berth.
Have a look-
