London’s flexible office sector is on track for significant expansion over the next five years, according to new projections from CBRE. The market currently represents about 12% of the capital’s total office footprint, but the firm expects this to climb to 20% by 2030, pushing total flex space to 50 million sq ft.
Growth is being driven by shifting occupier expectations and a steady rise in landlords embracing flexible models rather than relying solely on traditional leases.
Traditional Offices Quietly Joining the “Shadow Flex Market”
As tenant needs evolve, CBRE has identified an emerging category within the sector: the “shadow flex market.” This includes conventional office space that is not labeled or marketed as flexible, yet can be secured on adaptable terms through negotiation.
The firm says this hidden layer of flexibility is becoming increasingly important as businesses demand shorter commitments, turnkey space, and frictionless move-ins.
Landlords Step In With Their Own Flex Brands
Every major subsector of flexibility is expected to grow, but landlord-operated offerings are set to accelerate fastest.
CBRE projects that “brandlord” space — landlord-created and managed flex brands — will reach 3m sq ft by 2030, marking a 200% increase from current levels.
Managed flex space is also poised for a significant jump, with supply forecast to rise 70% to around 12m sq ft. This segment continues to attract occupiers seeking private, self-contained suites paired with flexible lease terms and bundled services.
Flexibility Becomes a Core Requirement
CBRE notes that defining the flex office ecosystem remains challenging due to its fragmentation, varying service levels, and the rise of hybrid formats. Even so, the firm maintains that a clear understanding of the sector is essential for assessing opportunity across Central London.
The common thread behind all categories — from managed suites to shadow flex — is the same: occupiers increasingly expect agility, simplicity, and service built into their workspace agreements.
