There a few of us UK / Europe-based Mustachians lurking on here.
It is harder than in the US, but it is possible to go the ERE / MMM route, if you are determined, can get your savings rate up to a meaningful %, and asset allocation is a whole other afternoon's research. If you are UK-based, you have tax advantages on dividend income, advantages of an ISA umbrella, but are limited by selection of GBP quoted ETFs, you are going to need to go global as well.
Suffice to say, the balanced multi-fund / ETF strategy, low cost, is the way to go. If you can shovel enough into such funds, the performance against broad market indexes, bond and equity, should not bother you. Again, the savings rate is the key to achieving FI.
