I spoke to a couple of UK IFAs, I didn't find them especially helpful. They were focussed on selling me "beat the market" funds and struggled to get on board with spending less to stop work sooner, rather than working more to spend more.
One made an egregious mistake and it really bothered me that he wouldn't accept that this was a big deal. I came to the conclusion that it was more work checking that they'd run their numbers correctly than just running the numbers myself.
