India has emerged as a key global hub for Global Capability Centres (GCCs), with flex offices playing a growing role in meeting enterprise demand for speed, scalability and quality. According to Vestian Research, India hosts over 1,750 GCCs operating through nearly 3,800 bases, accounting for more than 40 per cent of total office space demand over the past two years. Of the 1,400 flex centres across major Tier-1 cities, more than 475 currently house GCC operations. As GCCs become dominant occupiers, they are accelerating premiumisation within the flex segment. Across the top seven cities, 42 per cent of flex centres are green-certified and 69 per cent are located in Grade-A buildings. In contrast, around 62 per cent of GCC bases in flex spaces operate from green-certified centres, while 85 per cent are located in Grade-A assets, highlighting a strong preference for high-quality, sustainable workspaces. City-level data reflects this trend. Mumbai leads with 98 per cent of GCC bases in Grade-A flex buildings, followed by Hyderabad and NCR at 94 per cent and 93 per cent respectively. Green-certified adoption among GCCs is strongest in NCR at 81 per cent, followed by Hyderabad at 72 per cent and Mumbai at 68 per cent. GCC expansion is also driving flex growth beyond central business districts. Peripheral business districts now account for 77 per cent of flex space occupied by GCCs, compared to 61 per cent of overall flex stock, driven by better connectivity, competitive rentals and campus-style developments. Commenting on the trend, Shrinivas Rao, CEO, Vestian, said flex operators have become indispensable partners for GCCs by offering faster market entry, flexibility and enterprise-grade infrastructure required for rapid scaling. India’s flex market has expanded to 82.3 million sq ft across nearly 1,400 centres in the top seven cities, with the top 10 operators controlling 67 per cent of total stock. Bengaluru leads with a 33.2 per cent share, followed by NCR at 20.4 per cent and Pune at 14.7 per cent. Vestian projects India’s flex stock to exceed 100 million sq ft by 2026, supported by sustained GCC demand and continued upgrades toward premium, sustainable office environments.
