Is AI Changing London's Office Market? What a Year of Listings Data Shows
A year of flexible office listings in Kings Cross, Euston and Fitzrovia, Farringdon and Shoreditch, compared with Central London: where space is going, and why prices have not followed.
Artificial intelligence is now one of the most talked-about forces in the London office market. Leasing data shows how fast this has moved. CoStar figures show almost half of the office space let to AI companies in London in April 2026 was around Kings Cross and Euston, and Knight Frank has found smaller AI firms clustering in Clerkenwell, Farringdon and Shoreditch. The question for anyone looking for an office is simpler: is any of this showing up in what flexible offices cost and how many are available?
We track every flexible office listed on Rubberdesk each week. This analysis compares the main AI districts with Central London as a whole over the past year. The short answer: space in the AI districts is getting scarcer, especially at Kings Cross, Euston and Farringdon, but prices have not followed. There is no sign of an AI premium in flexible office rents.
How we measured it
- Source: weekly snapshots of every flexible office listed on Rubberdesk in London: serviced, private and managed offices.
- Areas: listings grouped by nearest station, which gives a consistent catchment over time: Kings Cross; Euston and Fitzrovia (listings nearest Euston, Euston Square and Warren Street); Farringdon; and Old Street and Shoreditch, plus Central London overall.
- Smoothing: each figure is a three-month average, comparing August to October 2026 with the same three months of 2025, to even out week-to-week swings when a large office is added or removed.
- Measures: the median private office rate per desk per month (rounded to the nearest £5), total flexible floorspace listed, and the number of listings.
What changed in a year
| Area | Median private office per desk | Change | Flexible floorspace listed | Change | Listings |
|---|---|---|---|---|---|
| Kings Cross | £920 to £715 | -22% | 161,000 to 51,000 sq ft | -69% | 117 to 62 |
| Euston and Fitzrovia | £685 to £565 | -17% | 158,000 to 112,000 sq ft | -29% | 100 to 87 |
| Farringdon | £695 to £625 | -10% | 394,000 to 297,000 sq ft | -25% | 277 to 223 |
| Old Street and Shoreditch | £595 to £600 | +1% | 767,000 to 684,000 sq ft | -11% | 502 to 456 |
| Central London | £700 to £680 | -3% | 4.50m to 3.96m sq ft | -12% | 3,485 to 3,163 |
Three-month averages, August to October 2025 against August to October 2026.
Finding 1: space is disappearing fastest around the Knowledge Quarter
Flexible floorspace on the market across Central London fell by 12% over the year. Kings Cross lost more than two-thirds of its listed space, Euston and Fitzrovia nearly a third, and Farringdon a quarter. Old Street and Shoreditch fell broadly in line with Central London.
That matches where the leasing data puts AI demand. Knight Frank counted almost 370,000 sq ft of AI-related lettings around Kings Cross and Euston, more than any other part of London, including Anthropic's 158,000 sq ft at One Triton Square near Euston. When offices in these districts come off the market, they are being taken more often than elsewhere, or not being replaced.
Finding 2: prices have not followed
If AI demand were pushing up what flexible offices cost, the districts losing space fastest would show the biggest rises. The opposite has happened. The median private office at Kings Cross fell by 22%, at Euston and Fitzrovia by 17% and at Farringdon by 10%, against 3% across Central London.
Much of that fall is about which offices are left. At Kings Cross, the offices that came off the market were larger and somewhat pricier than the ones still listed: an average of 23 desks against 11, priced around 6% higher per desk. With the bigger floors gone, what remains is a smaller and cheaper mix, so the headline median falls even if few individual offices have become cheaper. Either way, someone looking for a flexible office in these districts today is not paying an AI premium.
Finding 3: the choice is shrinking where AI teams want to be
The practical effect is choice. Kings Cross now has around 51,000 sq ft of flexible space listed, roughly 1,000 desks across all operators, and with the larger floors gone, only a small number of offices can take a team of 30 at any one time. Euston and Fitzrovia has around twice as much, Farringdon around six times as much, and Old Street and Shoreditch more than thirteen times as much.

Why AI demand is not pushing up flexible office prices
Research on AI occupiers helps explain the pattern. Penningtons Manches Cooper notes that larger AI firms tend to start in flexible space and move into permanent headquarters of their own once they scale, so their biggest requirements show up as conventional lettings, not as competition for flexible offices. Their leases are sized for growth: Bisnow reports recent deals sized for three or four times their current team, and they are taking whole buildings rather than serviced suites.
Nor do they need anything unusual. Knight Frank says it knows of no AI occupiers asking for extra power, cooling or connectivity, because the computing runs in data centres, so there is no specialist stock for them to bid up. The smaller AI firms that do use flexible offices are choosing Clerkenwell and Shoreditch partly because rents are lower. The result is fewer flexible offices on the market in the AI districts, but no premium on the ones that remain.
What it means if you are looking for an office
- Kings Cross or Farringdon: start earlier than you would elsewhere and be ready to decide quickly. Good offices are not staying on the market for long. Consider neighbouring areas such as Clerkenwell or Angel, a short walk or one stop away.
- Shoreditch and Old Street: the deepest market of the four, with prices steady at around £600 a desk. Good for growing teams that need room to expand in the same building.
- Euston and Fitzrovia: the closest alternative to Kings Cross, with about twice the space listed and some of the largest recent AI lettings nearby. Fitzrovia has the bigger choice of offices for teams of 20 or more.
- Uncertain headcount: if AI changes how many people you need, flexible terms protect you either way. Short agreements let you take more desks or give them back without a long lease.

What the data cannot tell us
- Why a listing leaves the market. An office comes off Rubberdesk when it is let, but also when an operator withdraws it or lists it elsewhere. Falling supply is a strong signal of demand, not proof of it.
- Who took the space. We do not know which occupiers moved in, so we cannot say how much of the change is AI companies rather than technology firms in general.
- Traditional leases. These figures cover flexible offices only. Conventional leased space in the same districts can move differently.
