Managed offices boom 582%,
JLL and Kitt report finds

London's office market is entering a new chapter. Fresh research from JLL and Kitt reveals how managed offices are moving into the mainstream, changing the way that space is leased, occupied and delivered across the Capital.

The managed operators' latest report, From Void to Value: Managed Offices Transforming London Offices, conveys just how quickly the sector is evolving. Its findings show that managed office space has grown by an impressive 582% since 2020, comfortably outpacing landlord-operated flex space (223%) and traditional serviced offices (20%), as landlords turn to managed solutions to reduce void periods, accelerate leasing and unlock greater value from their assets.

London is now home to around 20 million sq ft of flexible workspace, accounting for 8.1% of the capital's office stock and reinforcing its position as one of the world's most established flex markets. Managed offices are becoming a prominent part of that landscape, with 27% located in the City Core, 25% in Midtown, 22% in the West End and 16% in the Tech Belt, alongside a growing presence across South Bank and other London submarkets.

Meanwhile, the supply of Cat A+ space continues to climb. Almost 7 million sq ft was on the market across Central London at the end of 2025 - up more than 60% year-on-year - as landlords respond to growing demand for move-in-ready offices.

The report suggests that managed space is playing a key role in that shift. In fact, 64% of landlords say reducing void periods is one of the biggest reasons for adopting the model, with some occupiers moving from first viewing to occupation in as little as eight weeks.

Charles Fraser, Head of Flex at JLL, said: “Businesses have had to navigate an unprecedented period of uncertainty while dealing with rising costs across the board. As a result, occupiers are progressively prioritising flexibility, looking for shorter lease commitments and ways to reduce upfront capital expenditure. That's driving strong demand for fully fitted managed and serviced office space."

He added: "The market has fundamentally shifted, and the flex sector is only going to become a bigger part of the office market in the years ahead."

For occupiers, the attraction is obvious: no major fit-out costs, less upfront capital and the flexibility to grow or shrink their footprint as business needs evolve. Landlords, meanwhile, are seeing the upside too, with managed offices offering the opportunity to command higher rents, while bringing vacant space to market at a faster rate than traditional leasing models.

Founder and Chief Executive Officer at Kitt, Steve Coulson, said: “The London office market is no longer in a state of ‘recovery’ - it has fundamentally changed. Managed offices have moved beyond being a niche flexible product to become a mainstream investment strategy, helping landlords reduce voids, accelerate leasing and unlock more value from existing assets. The data shows this isn't a passing trend; it's a structural shift in how office space is owned, operated and occupied.”

The momentum doesn't look to be slowing anytime soon either. According to JLL's EMEA Pulse Survey, 32% of organisations expect to increase their use of flexible workspace over the next three years, with flexibility now sitting just behind connectivity and building security as a key workplace priority.

One thing is becoming clear: managed offices are no longer an emerging trend - they're rapidly becoming a defining feature of London's office market.
