In 2025, London’s office landscape tells a story of evolution rather than recovery. The city is no longer merely adapting to hybrid work, it’s redefining what “the office” actually means.
While the market continues to stabilise post-pandemic, it’s clear that priorities have shifted for both tenants and landlords. Flexibility is no longer a nice-to-have, but a necessity. And sustainability isn’t a future goal, it’s a baseline expectation.
This case study dives into the key trends shaping London’s office market in 2025: from pricing pressures and supply imbalances to borough-level shifts and the ongoing rise of flex space.

Market Context and Demand Drivers
Quality and Sustainability
Tenants are overwhelmingly favouring best-in-class offices. Over half of recent leases have gone to BREEAM “Excellent/Outstanding” buildings.
As a result, landlords of certified space are achieving rent premiums ≈15% above non-certified offices.
Hybrid and Flexible Work
The rise of hybrid models means that occupiers want an agile workspace. For example, roughly 10% of Central London offices are now flexible/coworking spaces (up from 6% in 2019), and inquiries for such space are +14% year-on-year, over 200% above pre-COVID levels.
More than half of tenants report needing more collaborative or flex-space to accommodate hybrid teams.
Sector Mix
London’s traditional occupiers still dominate take-up. Insurance and financial firms accounted for about a third of all 2024 transactions, followed by tech/media at ~16%.
Professional and legal services also contributed a record number of deals. Notably, serviced-office operators themselves now make up ~7% of demand, reflecting appetite for fully-managed, plug-&-play solutions.
Occupier Trends
Contrary to early-pandemic downsizing, many businesses are expanding. A recent survey found 54% of London occupiers plan to increase their space (only 16% plan cuts).
Pre-letting is commonplace, and projects like One Olympia and others are more than 40% leased before completion, showing confidence in future demand.
Pricing Trends in 2025
Central London Premiums
Prime West End rents are now around £130–150/sq ft (e.g. Mayfair/St James’s). The City of London commands roughly £70–100/sq ft. In practice, record deals (Mayfair hit £277/sq ft in a recent lease) underscore the strength at the top end.
Emerging Hubs
Docklands and East London hubs offer lower rates. For example, Docklands prime offices rent for around £40–60/sq ft, and new developments at Canada Water or Canary Wharf go for £40–65/sq ft. These modern campuses attract tenants seeking value and amenities.
Outer London Affordability
Office space on the periphery remains much cheaper. In many Outer London corridors (aided by the Elizabeth Line), rents are in the £25–35/sq ft range.
For instance, Hanwell or Southall spaces can be found in the low £30s, while Abbey Wood or Romford are in the high £20s.
Flexible/co-working desks likewise reflect the gap, as London-wide, the average flex-desk costs roughly £515/month, but in non-core boroughs like Croydon, Kingston or Enfield it drops to £200–300/month.
Differential Growth
Prime rents are rising fastest in top submarkets. Areas like Chelsea, Battersea, Covent Garden and parts of the West End are seeing record lease rates.
By contrast, East and South East London offices remain relatively soft, with lower base rents and longer-term rental growth lag.
Availability and Vacancy Patterns
London’s overall office availability has tightened in 2025. After peaking near 9.5% vacancy in early 2024 (up from 8.9% in 2023), the market rebounded so that by late-2024 City-wide vacancy was around 7.5%.
Even within submarkets, the picture varies: core West End and Midtown locations are now sub-8% vacant (West End ~6.5%), whereas pockets like Docklands or Stratford have ~10–17% availability due to recent completions.
A summary of 2025 average vacancies:
- West End ~6.5%
- City ~8.8%
- Docklands ~10.2%
- Shoreditch ~7.8%
- Canada Water ~9.5%.
Notably, only about 15% of central London stock is on the market (tenant-controlled). High pre-letting is locking in tenants and further constraining available supply.
Borough-Specific Patterns
The market shows clear geographic splits: prime central boroughs command the highest rents and tightest vacancies, while Outer London offers scale and affordability. Key observations:
- North London: Boroughs like Barnet, Camden and Enfield have seen moderate rent growth of around +5% YoY. Significant redevelopments (e.g. Brent Cross Town in Barnet added around 250,000 sq ft of offices in 2025) and improved transit (Elizabeth Line’s Brent Cross West now <12 min to Central) are boosting local demand.
- West & Outer London: The new Elizabeth Line corridor has uplifted west-side boroughs: in Hanwell/Southall average asking rents are in the low £30s/sq ft, while Ealing and West Drayton are in the mid-£20s. Heathrow and Stockley Park locations are now among the fastest-growing markets outside the City. Established West London hubs (e.g. Chiswick, White City) see strong corporate interest, and parts of Hammersmith/Ealing still average only ~£40–45/sq ft.
- East & South East: Traditional riverbank hubs remain mixed. Canary Wharf (in Tower Hamlets) is a major financial district with prime serviced offices, but it still trades at about £57–60/sq ft, well below West End levels. Nearby emerging hubs (Canada Water, Greenwich) offer 9–10% vacancies and modern campuses at £40–65/sq ft. Stratford and East Bank (Olympic site) attract creative and tech occupiers on large floorplates, though overall East London take-up remains a small share of the city total.
- Docklands & Fringe Markets: Docklands’ rents and vacancies reflect its appeal for cost-sensitive tenants. Croydon averages ~£41/sq ft, making it a value alternative for outer London. By contrast, Kensington and Chelsea boroughs still see triple-digit rents (~£100/sq ft or more), illustrating the sharp central-peripheral divide.
Flexible Workspace Growth
Flexible and co-working spaces have surged. London’s core now hosts around 70% of the city’s flexible office take-up. Key trends:
- Market Share: Flexible offices comprise about 10% of Central London stock today, up from around 6% in 2019. Landlords and operators are racing to convert space, and around 60% of owners plan to offer flexible solutions in the coming years.
- Demand Uptick: Demand indicators are high – inquiries for flex space are +14% year-on-year, which is more than double pre-pandemic levels. Not only startups but large corporates (often via Managed Service Providers) are expanding into coworking.
- Pricing: The average desk in a London flex space is now about £515/month. Premium locations (e.g. Soho, Marylebone, King’s Cross) command £700–900/month or more; the very top tiers (some West End or Midtown clubs) can exceed £1,100/month.
- Occupancy is high: Central City and Southwark centres are around 90% full on average. By comparison, outer-borough flex spaces remain cheaper (around £200–300/month).
Tenant Preferences and Leasing Behavior
London tenants in 2025 are clearly favouring sustainability, amenities and flexibility:
Sustainable Space
A huge majority of deals are for green buildings, and roughly 60% of 2024 office leases were in BREEAM Excellent/Outstanding space.
Such assets have near-zero vacancy (0.3–0.5% in City/West End) and allow rents about 15% above non-certified levels. This “vote with wallet” trend is reshaping leasing.
Footprint Expansion
With lower overall vacancy, companies are getting more space. More than half of the surveyed occupiers plan to expand or refurbish their offices (versus only ~16% downsizing).
At the same time, many are signing leases early: about 42% of new development space in 2025 was pre-let, reflecting cautious but forward-looking planning.
Lease Flexibility
Tenants increasingly demand shorter, flexible terms. Landlords have taken note – roughly 60% of owners expect to convert parts of their portfolios into flexible offerings within five years.
Accordingly, serviced office operators are growing (now ~7% of market demand), and break clauses or rolling terms are becoming common in conventional leases.
Amenities & Layout
Companies continue to reconfigure offices. For example, amenity space (lounges, collaboration zones, fitness areas) has risen from ~5% to >20% of an office’s area on average.
Layouts now dedicate over 40% of space to collaborative/social functions, mirroring employee expectations in a post-pandemic workplace.
Outlook
Looking ahead, analysts expect continued momentum in London’s office sector through 2025. Tenants and investors alike are adapting to macro conditions and new work models. Importantly, demand for well-located, high-spec offices remains robust – companies are willing to pay premiums for sustainable, amenity-rich buildings.
Both traditional leases and flexible tenancies will grow; over the rest of 2025, more refurbished stock and new flex inventory should come to market.
In summary, London’s 2025 office market is one of rising rents and strong occupier demand at the top end, uneven availability across boroughs, and an accelerating shift towards green, collaborative workspace solutions.
