Where I worked back in the 80s, we did loads of endowment mortgages (in the days before regulation and independent financial advisers). We were "just" a firm of accountants who arranged pensions and mortgages etc for our clients (no one else, just our clients, as a service!). Because we were in a profession where detail mattered and we were used to "dotting the I's and crossing the t's" we were really on the ball when it came to advice, warnings, etc. I understand solicitors' firms were the same with any "financial services" they offered!
@Badbadbunny I had an endowment mortgage in the mid-90s. When I sat with my mum and the mortgage advisor, they both waxed lyrical about how the endowment would pay off the mortgage, and I'd even probably have a nice wee sum to go on holiday with. I asked what would happen if the value of it fell. He said that wouldn't happen because they always made sure they set the value of it so the payments would always at least cover it. I pushed, but he basically shut me down as a silly young woman who didn't understand it. I knew there was a risk, took it anyway and figured I'd be selling the flat long before the mortgage was due and even if I didn't, it was 25 years away so I'd worry about it later (I was 19 and a student.) Of course, I got a letter about 5 years later saying the endowment was in shortfall and I'd need to find extra money. I was planning on selling the flat anyway so it wasn't a problem to me.
About 3 months later, I got a letter from the firm that had taken over the firm who advised me and they said, we are very sorry that guy didn't do what he was supposed to, here's some money to help towards the issues with your endowment.
I am certain there were people who were advised well and knew the risks. If the paperwork was in order, they wouldn't get "compo". There were also people who were well advised, knew the risks, but got "compo" because of administrative failures. But there definitely were people who were mis-selling and not advising. Had it been my mum who was buying the mortgage off that guy, she would have been certain it would be fine. Indeed, her own mortgage had a shortfall which she was shocked to discover, but it turned out she had a second endowment policy from an older mortgage which she forgot about and that covered it. She tried to get some payback, but they produced the piece of paper she had signed warning her of the risks. Had she been a WASPI (I think she missed it by a couple of years) she absolutely would have been shocked to discover the situation when she retired, despite it being everywhere and getting letters etc. She still whines about Gordon Brown stealing her pension but when pressed she has no idea what all that was about.
