Practical Information

Singapore is well known for being a modern and well-organised country. Just like any destination, though, it has codes and rules to be aware of when planning a visit.


Most of Singapore’s hotels and restaurants include a 10 percent service charge in their bills. Even where such a charge is not automatically included, tipping is still optional. In such a case, you could leave a 10 percent tip as a gesture of satisfaction for good service. This also applies also to taxis.

At Changi Airport, tipping is actually prohibited as all employees receive wages.

Local time / Business hours

Singapore's time zone is GMT+8. Singapore does not participate in Daylight Savings Time.

Although five-day work weeks are becoming more common, most companies are open from Monday to Friday between 9am and 5pm, with a lunch break between 1pm and 2pm; Saturday hours are 9am to 1pm.

Most shops are open from 10:30 am to 9:30 pm (Sundays included) especially in malls. If you wish to visit a specific shop, it is wise to check with them regarding their hours, as they may be different.

Singapore’s tap water is safe to drink without any further filtration or treatment and complies with World Health Organisation drinking water guidelines. Even though there are no natural fresh water sources within the country itself, Singapore has developed a strong and reliable water supply system, comprised of four sources, known as "The Four National Taps":
• Water from local catchment areas
• Imported water from Malaysia
• Desalinated water
• Highly-purified reclaimed water (NEWater)
