As part of the £177m contract Mitie will provide reactive repairs and planned maintenance works to over 17,000 properties across the London borough.
This is the second strategic partnership Mitie has with the west London council having being awarded a three-year £30m cyclical painting contract earlier this year.
Mitie will employ a 24/7 contact centre to book convenient times for repairs to take place and hopes to save the borough £20m on its repair bill over the next ten years.
Cllr Andrew Johnson, cabinet member for housing said: “The council carries out around 50,000 repairs a year and when we ask residents what matters most to them, repairs comes out on top time and again.”
