The move reunites the pair with Lowe's executive creative director, Ed Morris, whom they worked with at TBWA\London.
Most recently, Reid and Broadhurst worked at Fallon Minneapolis, having followed Paul Silburn, TBWA's former creative director, when he defected to the US agency last year. After Fallon dismissed Silburn in January, the pair returned to the UK.
Reid, a copywriter, and Broadhurst, an art director, will work across Lowe's accounts, including projects for Stella Artois and Sure.
Morris said: "Good talent is thin on the ground - the boys had their pick. They came here. Their faith will pay off."
