Managed offices - from void to value

• Explosive growth: Managed office space grew 582% between 2020-2025, establishing itself as the fastest-growing workspace segment in London.
• Landlord advantage: Opting for managed partnerships helps landlords mitigate capital risk, convert idle inventory faster, and deliver modern workplace experiences that align with today’s occupier expectations.
• Building strategy: Landlords of smaller, older assets can use managed solutions as a vehicle to reposition and monetise obsolete stock—especially in submarkets experiencing rising rental momentum.
• Corporate uptake: Corporates are increasingly using managed offices not only for satellite teams but as part of a deliberate portfolio strategy. Owners who align with this demand—through quality, speed, and flexibility—can capture a larger share of an expanding occupier base.

London's flexible workspace sector is experiencing unprecedented transformation, with managed offices emerging as the fastest-growing segment and fundamentally reshaping how landlords and occupiers approach commercial real estate. JLL research reveals that managed office providers have achieved a staggering 582% growth rate between 2020-2025, significantly outpacing traditional serviced offices at 20% and landlord-operated spaces at 223%.

The flex sector now represents approximately 8.1% of London's office stock, totalling around 20.0 million sq.ft.—a substantial increase from pre-COVID levels of 15.0 million sq.ft. This growth reflects a fundamental shift in workplace preferences accelerated by hybrid working adoption and evolving business requirements for operational agility.

Managed offices represent the bridge between traditional leasing and flexible workspace, offering private, self-contained spaces designed and run by third parties on behalf of single tenants. Unlike serviced offices where occupiers share amenities, managed spaces provide exclusive access to all facilities while delivering move-in ready solutions through a single monthly fee covering fit-out, utilities, and technology management.

For landlords, the financial benefits are compelling. Managed solutions enable significantly shorter sales cycles—as low as eight weeks from viewing to occupation—while delivering higher rental yields and reducing void periods. Research shows that 64% of landlords identify void reduction as a major driver for engaging with managed space, directly addressing one of the most significant cost pressures facing property owners.

Occupiers benefit from eliminated upfront capital expenditure, reduced fit-out timelines, and operational flexibility that allows businesses to scale space requirements without heavy dilapidation liabilities. This combination of speed and flexibility translates directly into cost savings and operational resilience for companies navigating uncertain business cycles.

Managed offices show distinct geographic preferences, with higher concentrations in Midtown and the Tech Belt compared to other flexible workspace offerings. This distribution reflects the model's effectiveness in areas with robust office demand and higher rental values necessary to support the financial structure.

The sector shows strength in smaller, historic buildings, with more than three-quarters of managed offices in buildings under 10,000 sq.ft. originally built pre-war. Most flexible offerings work in buildings smaller than 50,000 sq.ft., with managed offices specifically concentrated in sub-10,000 sq.ft. properties where they can achieve 90% space use.

This positioning creates significant opportunities for owners of smaller office buildings, where flexible workspace penetration remains relatively low at less than 5% in sub-10,000 sq.ft. buildings, compared to 14% penetration in buildings between 25-50,000 sq.ft.

Transaction data reveals managed deals now account for 25% of all flexible workspace transactions, with average deal sizes of 6,600 sq.ft. compared to 4,100 sq.ft. for serviced offices. Demand patterns show increasing appetite for larger spaces, with requirements over 6,000 sq.ft. growing 103% between 2023-2025.

Corporate adoption continues expanding, with JLL's EMEA Occupancy Planning Survey showing access to flexible solutions ranking as the third most valued amenity for office decisions, behind only connectivity and building security. Nearly a quarter of organisations now commit to flexible workspace terms exceeding 24 months, up from 7% in 2024.

The emergence of Cat A+ fitted space represents another dimension of market evolution, with 7.0 million sq.ft. marketed by end of Q4 2025—a 60% annual increase. This pre-configured space, representing almost one-third of available market supply, shows landlord recognition of occupier preferences for move-in ready solutions.

Approximately 60% of Cat A+ space is marketed directly by landlords, with around half offered in units under 10,000 sq.ft. totalling 1.8 million sq.ft. This trend indicates landlords' strategic pivot toward fitted offerings that reduce sales cycles and attract tenants seeking immediate occupancy solutions.

The research identifies clear strategic opportunities for landlords with smaller, historic office buildings looking to enhance asset performance. Managed offices provide a repositioning strategy that can unlock value in secondary stock, with 68% of survey respondents naming this as a key driver.

Location analysis reveals specific submarket opportunities, with varying levels of managed office provision relative to market size across London's commercial districts. Understanding competitive positioning and local market structure becomes critical for successful centre delivery and sustainable returns.

For occupiers, the data suggests continued expansion in flexible workspace adoption, with 32% of organisations expecting increased usage and 92% of respondents believing managed office demand will grow over the next 2-3 years. This momentum creates compelling investment rationale for landlords considering managed office partnerships.

The managed office sector's growth trajectory appears sustainable, supported by fundamental shifts in workplace preferences, technological advancement, and corporate real estate strategies emphasising operational agility. With average commitment lengths extending and deal sizes increasing, the market demonstrates maturation while maintaining flexibility advantages that initially drove adoption.

The combination of reduced void periods, enhanced rental yields, and alignment with evolving occupier expectations positions managed offices as a strategic asset class capable of delivering superior financial returns while meeting irreversible changes in workplace demand.
