The duo have signed long-term deals and will arrive at Rodney Parade in the summer. Wales qualified scrum-half Davies began his professional career with Nottingham whilst studying at Nottingham Trent University.
The 24-year-old was then spotted by Top 14 heavyweights Stade Francais and secured a move to Paris. He was called up to the England U20s for the Junior World Cup during his time in France before moving back across the English channel to Wasps – where he made eight appearances.
Davies arrives with Wasps team-mate Ed Jackson. The English back-row played under Dragons Director of Rugby Lyn Jones at London Welsh and has impressed with three tries in his 25 senior appearances for the Coventry club.
The powerful ball carrier captained England U18s and U16s, during his time in Bath rugby’s academy. The back row signed a full-time contract with Bath in 2007 and made his debut for them against Leicester Tigers in 2008. Jackson then moved onto Doncaster Knights in the English Championship before making the move to London Welsh in 2013.
Director of rugby, Lyn Jones commented: “I’m delighted both have committed to us, they will be two good signings which will increase the ability of our squad in Rugby World Cup year. Kingsley Jones and I have worked closely with Ed Jackson and we know how good he can be.
“As for Charlie he has always played to a high standard for Wasps since his return from Stade Francais. His roots are in Porthcawl and will prove to be an exciting signing as he joins forces with Sarel Pretorius and Luc Jones for the number 9 shirt next season.”
