Premium 531 serves housing board estates, private estates and condominiums around Simei and Upper East Coast with connections to Suntec City, Marina Centre and Shenton Way, eliminating the hassle of transferring between different modes of transport. At the same time, SBS Transit’s Express 10e also offers peak hour connections between Upper East Coast and Shenton Way at a cheaper price, but takes a longer journey by not plying along expressways.

Since its introduction in 2007, Premium 531 has experienced considerably high demand from the niche market, mostly from the private housing areas around Upper East Coast, where 531 is a the fastest bus route to the CBD despite its high fares. High capacity articulated buses were deployed on this service duing its initial days of service, when there were just 2 morning departures and buses were filled to the brim (despite the Premium no-standing regulation back then), and some buses (e.g. TIB1081S) were re-tuned for better climbing of Benjamin Sheares Bridge. Articulated buses were eventually removed when more weekday peak hour trips were added.

Originally operating with 2 morning and 2 evening trips, Premium 531 operated with 6 morning and 3 evening trips at its peak under SMRT, making it among the most successful Premium routes around. Most trips were fully seated.

Transfer of Operator to Commute Solutions

Under Commute Solutions, the cash fare for Premium 531 was raised from $5.50 to $6.00. EZ-Link fares remain at $5.50.
AM Departures were reduced from 6 AM trips to 5 AM trips, while PM Departures were also reduced from 3 PM trips to 2 PM trips.

AM Departures were re-timed and reduced to 4 trips between 0740 to 0805hrs after the takeover by Commute Solutions.

Subsequently, from 1 April 2020, the 2 morning trips at 0740hrs & 0755hrs were reduced to only 1 trip at 0750hrs.

Cash fares were increased to $7.00 from 03 Jan 2017.

More Trips were subsequently reduced.

Commuters may also pre-book passes from the ShareTransport App.

    2 days in a row (yesterday and today) the last bus was a no show. I might as well voice my other concerns here: i noticed on 2 occassions the driver was using his cell phone while driving; and for 5.50, i expect the contractor to at least provide commuters with a decent bus, not one that squeaks throughout the journey. And on particular one day with heavy rain, it was leaking water via the aircon vent.
