Main Upgrading Programme

The Main Upgrading Programme, or MUP, was formally launched in March 1992, initiating a massive physical upgrading exercise for the thousands of flats built by the Housing and Development Board in Singapore.
History
In March 1992, the government experimented with the concept of upgrading public flats while they were still being occupied on 6 selected precincts in a pilot phase, namely in Marine Parade, Kim Keat, Telok Blangah, Ang Mo Kio, Lorong Lew Lian and Clementi. The 15-year programme covers only precincts 18 years or older, and involves upgrading works to the precinct's surroundings, the blocks themselves, as well as within each individual dwelling unit.
The demonstration phase was a success, and hence, was expanded island-wide. In mid-1995, the programme covered 40 precincts, and has since expanded to over 100 today.
Home Improvement Programme
The Home Improvement Programme (HIP), a new programme announced by HDB in August 2007, is set to replace the Main Upgrading Programme (MUP). The HIP helps lessens deal with common maintenance problems in ageing flats, such as spalling concrete and ceiling leaks, in a systematic and comprehensive manner. It also offers lessees a choice on the works they want to be included in the upgrading of their flats. Flats built up to 1986 which have not undergone the Main Upgrading Programme are eligible for HIP.
