Wards at St Helier Hospital are being upgraded thanks to a multi-million pound refurbishment.
The investment will see wards at the hospital modernised, 133 windows replaced, repairs made to the roof and a new concrete render on B and C blocks, ensuring better facilities for patients, visitors and staff.
Cllr Ruth Dombey, Lib Dem Leader of Sutton Council, said: "I am so pleased to see all the scaffolding up around our hospital -- it shows the true scale of this £28 million refurbishment, the most significant in St Helier's history.
"It has only been possible because Sutton Council made it a requirement when they bought land from the NHS for the development of the London Cancer Hub in Belmont.
Ruth added: "The agreement was that the NHS earmarked the money they received from the Council for the improvements at St Helier Hospital.
"It's clearer than ever that the Liberal Democrats are the only party committed to investing in our hospital and making it the best it can be."
