Morningstar UK selected the winners of the awards using a quantitative methodology with a qualitative overlay that considers the one, three, and five year performance of all eligible funds.
The ratings agency also adjusts returns for risk using Morningstar Risk, a measure that imposes a higher penalty for downside variation in a fund's return than it does for upside volatility.
Christopher Traulsen (pictured), director of manager research for EMEA at Morningstar, said: "When compared to peers, all of our winners delivered strong results in 2015 and over the five years ended 31 December, after taking risk into account.
"These funds and fund houses have demonstrated they have the ability to earn strong returns over the long-term without undue risk. We believe that taking a patient, long-term view to investing will ultimately help investors reach their financial goals."
