Flexible workspace is no longer a niche in London’s commercial property market — it’s becoming the defining feature of the city’s post-pandemic office landscape. New analysis from CBRE, Knight Frank, and Savills’ Workthere platform shows that flexible and serviced offices now account for around 12% of total office stock in London, up from less than 6% a decade ago. That share is expected to rise steadily to around 20% by 2030, as more companies choose shorter leases and landlords pivot toward hybrid, operator-led models.
The trend reflects a fundamental shift in how London’s businesses use space. Hybrid working has settled into a pattern of three or four days in the office, and employers are rethinking long-term leasing commitments. Companies want flexibility — the ability to expand or contract footprints quickly without being tied into 10- or 15-year leases. As a result, demand for plug-and-play, managed offices has surged, with flexible providers such as WeWork, IWG, TOG, and Huckletree reporting occupancy rates of above 85% in the first half of 2025.
Landlords have been quick to respond. A growing number of major owners are setting aside entire floors for short-term, fully fitted offices — a model now known in the industry as “landlord flex”. The approach allows owners to capture premium rents and appeal to tenants who want high-quality space without the upfront cost of a full fit-out. Many new developments in the City and West End are being designed with shared amenities, plug-and-play services, and adaptable floorplates that can switch between traditional and flexible leasing depending on demand.
The economic logic is clear. London’s office vacancy rate remains high — around 9.5% overall, according to Knight Frank — but in the newest, best-connected buildings vacancy is below 2%. These Grade A spaces, which often include flexible office components, continue to command strong rents. By contrast, older, energy-inefficient offices are struggling, leaving landlords with little choice but to refurbish or convert. The rise of flexible workspace is accelerating this “flight to quality,” pushing owners to upgrade buildings for modern occupiers who expect sustainability, technology integration, and top-tier facilities.
For investors, the growing flex sector represents both opportunity and challenge. Managed office operators often sign shorter management agreements rather than conventional leases, shifting income risk from tenants to landlords. Yet investors increasingly see flex as an essential part of asset value — a way to maintain high occupancy and generate footfall in buildings that might otherwise sit empty. Analysts estimate that by the end of the decade, flexible and managed offices could represent a fifth of all London office stock, supported by consistent corporate demand and an increasingly professionalised operator base.
Critics, however, warn that rapid growth could expose the sector to volatility if the economy weakens. Flexible offices can be highly sensitive to downturns, as occupiers can downsize quickly and operators bear much of the cost burden. The collapse of WeWork’s US operations in 2023 was a reminder of how vulnerable the model can be to over-expansion and rising borrowing costs. London’s market has avoided a similar crisis by focusing on smaller, service-led operators and landlord-backed models, but some analysts still see the pace of new supply as a potential risk.
For the city as a whole, the rise of flexible space marks a decisive break from the traditional office leasing model that dominated for decades. The capital’s workspace is becoming more diversified and more fluid, with occupiers using different types of space for different needs: core headquarters for permanence and identity, flexible offices for project teams and overflow, and home offices for focused work. This hybrid infrastructure is reshaping the economics of London’s property market, driving demand for sustainability upgrades, smart-building systems, and amenity-rich environments.
If current forecasts prove accurate, London’s flexible workspace footprint could grow by almost 8 million square feet over the next five years — the equivalent of adding another Canary Wharf-sized cluster of managed offices across the capital. It’s a transformation that speaks not only to how people work but also to how London’s property market is evolving: less about ownership, more about use; less fixed, more adaptable.
In a city that thrives on reinvention, flexibility has become the new measure of strength.
