The 'Big Six' energy supplier believes the Manchester based business could be one way in which it helps itself meet government quotas on energy efficiency.
Founded in 2003, Matrix says it can help reduce a firm's energy use by up to 40% through its system which can control energy use remotely via its centre in Glasgow. This means it can turn off air-con, lights and other such equipment at the drop of a hat.
E.On Connecting Energies chief executive, Herve Touati, said: "This transaction is an important strategic move for us, allowing us to expand our position in the fast-growing energy efficiency market.
"It adds a sophisticated, innovative offering to our existing services portfolio. We see tremendous opportunities from the combination of Matrix's deep data-led building energy expertise with our capital-led energy efficiency and on-site generation capabilities."
The UK's energy suppliers are under increasing pressure from the government to meet energy efficiency standards.
Through its Green Deal and ECO initiatives, energy suppliers such as E.On are obliged to help out energy consumers by offering loans on energy improvement measures including the fitting of new boilers, wall insulation or other such measures designed to cut down domestic carbon emissions, and a homeowner's energy bills too.
