I would say it depends on whether you furnished the flat or the owners did. Additionally, I suppose it would depend on how much you accumulate and the valuation/sentimental/replacement value would be if you were to lose it all in a fire or flood. Most renters insurance will also provide you an allowance to rent suitable lodgings until you can get the flat repaired as well, but at the end of the day, it's really up to you. If you have all electric utilities you might think about foregoing the Insurance if you are high enough not to have to worry about flood damage. On the other hand, I would definitely carry some sort if you have gas appliances like oven, burners, hot water heaters, etc., be they bottled gas or piped gas from PS (PUB). Check local insurance companies like NTUC Income, Great Eastern, AIA, AIG, etc.
