The Main Upgrading Programme, or MUP (Chinese: 主要翻新), was formally launched as the Singapore government’s pioneer housing upgrading programme in 1992, by then Prime Minister Mr Goh Chok Tong. Under the MUP, residents enjoyed an improved living environment without the need to move out from their familiar surroundings. The MUP has been brought to 128 precincts island-wide, benefitting 131,000 households.
