A landlord commits several hundred thousand pounds to fitting out a vacant floor with furniture, meeting rooms, breakout space and finished ceilings, technology and lighting — before any tenant has signed anything, and in some cases before any tenant has even viewed the space. A decade ago this would have looked like an unusual gamble. Today, in parts of the office market, it has become an established way of competing for occupiers, and the reason is not fashion. It reflects a genuine transfer of capital risk from occupier to landlord that is reshaping what an office letting actually is.
The shift is most clearly documented in smaller Central London lettings. Savills’ August 2026 Central London Office Market Watch reported that 70% of City transactions and 74% of West End transactions below 10,000 sq ft had been agreed on a fitted basis during the year to date. Those figures do not describe the whole UK office market, nor do they establish that every landlord completed the fit-out speculatively before finding its tenant. They show the strength of demand for a finished office; deciding how much capital to commit before a letting is secured remains a separate judgement.
From shell-and-core to plug-and-play
The traditional office letting model divided responsibility fairly cleanly: a landlord delivered shell-and-core accommodation and then, typically, Cat A space with base building services and finishes, while the occupier took on the capital cost, design risk and project-management burden of turning that space into a working office, usually through a Cat B fit-out. That division made sense when occupiers had long lease terms over which to amortise their own expenditure, and when the workplace itself changed relatively slowly. Landlords are now delivering space several steps further along that spectrum — Cat A+, fitted and furnished, and in some cases genuinely ready to occupy without a substantial tenant-led project. The terminology varies by adviser and building, but the British Council for Offices’ distinction between Cat A+ and managed space is useful: Cat A+ provides a finished product without the ongoing service package of a managed or serviced office. The underlying shift is in who funds and owns the initial workplace, not necessarily who operates it once the tenant moves in.
Why the capital is moving
Several forces are pushing in the same direction at once, and it is worth being precise about which ones are actually driving the shift rather than simply describing what is happening. Fit-out costs have risen sharply, which makes the capital commitment a tenant faces at lease signing considerably greater than it once was, particularly for smaller and mid-sized businesses without an extensive in-house property function. Knight Frank’s February 2026 London research put Cat A base fit-out costs at around £70 per sq ft against £40–£50 five years earlier. That is not the cost of installing a fully furnished Cat A+ office, but it illustrates the pressure beneath the wider shift. Decision horizons have shortened too: businesses unsure about future headcount, hybrid working or their own direction are less willing to spend heavily on a bespoke office whose usefulness may change before the capital has been recovered through occupation. CBRE’s September 2026 European occupier research reflects that tension, with investment concentrating into flagship headquarters while occupiers look for greater landlord contributions and capital-light options elsewhere in their portfolios.
Speed matters at both ends of the transaction. An occupier can move into a fitted office without waiting for the months of design, procurement and installation that a self-funded Cat B scheme may involve; a landlord offering the finished product may secure a commitment from a business unable or unwilling to undertake that work. But the fit-out has to be funded and delivered by somebody. If the landlord completes it while the floor is still vacant and it then takes months to find an occupier, the whole void period may be no shorter than under a conventional letting. The advantage lies in removing a barrier for the incoming tenant and potentially accelerating occupation, not in an automatic saving of every month spent preparing the space.
The tension a landlord cannot fully escape
Delivering fitted space before securing a tenant creates a genuine strategic tension that a landlord cannot design its way out of, only manage. A highly generic fit-out — neutral finishes, conventional desk layouts, unbranded breakout space — risks feeling bland and undifferentiated, doing little to win a letting against a comparably specified competing building. A highly specific fit-out — heavy branding, unusual desk density or a layout built around one particular way of working — risks narrowing the pool of occupiers who can picture themselves in the space at all, potentially excluding exactly the tenant who would otherwise have taken it. The landlords getting this right are treating the fit-out as a considered design exercise aimed at a realistic target occupier for the particular building and location, rather than either choosing the cheapest neutral finish or commissioning a statement interior that appeals to fewer businesses than the letting strategy requires.
The decisions within that design exercise carry consequences beyond the marketing photographs. Desk density set too high can make a floor feel cramped rather than efficient; set too low, it can appear expensive relative to the achievable rent. The balance between private rooms, collaboration space and open desking needs to reflect how likely occupiers work, while furniture, technology and acoustic treatment have to withstand use and, ideally, the next letting. There is also room between committing to a speculative design and completing an entire office without a tenant. According to fit-out contractor Oktra’s account of GPE’s Elsley House refurbishment, the landlord prepared a flexible design for a newly vacant floor and secured Northzone before construction was complete. The example illustrates how a landlord can make the product legible to prospective occupiers while retaining some of the decisions, and expenditure, until a letting has become more certain.
Does fitted space narrow or widen the tenant pool
There is a genuine argument on both sides of this question, and a landlord deciding how far to go with a speculative fit-out needs to weigh them against each other. Fitted space can widen the realistic pool of occupiers by removing the capital and project-management barrier that might otherwise prevent a smaller business from considering the building at all — a finished suite lets a business with limited internal resources start operating without commissioning a fit-out of its own. At the same time, a particular configuration can narrow the pool: an unusual desk density, cellular layout or strongly styled interior will appeal to occupiers who match it and much less to those who do not, in a way that a neutral, unfitted floor avoids precisely because it leaves those choices to the incoming business. Neither effect can be assumed from the Cat A+ label alone. It depends on who is likely to rent that particular floor, for how long, and how much adaptation will be possible without undoing the landlord’s investment.
Reading the economics from both sides
For a landlord, the appraisal genuinely has to weigh several factors against each other rather than assuming the trade is automatically favourable. Upfront capital expenditure is real and immediate, often committed before any rental income is secured. Against that, fitted space may support a higher headline rent, reduce an incentive package that would otherwise compensate a tenant for its own fit-out, and shorten the delay between agreement and occupation. Set against those gains is the risk of having fitted the space for the wrong occupier, or at the wrong cost, and of finding that much of the expenditure needs to be repeated when the first tenant leaves. A suite that lets quickly but requires expensive alteration on every reletting may prove less profitable than a simpler product that survives changes of occupier.
A higher fitted rent is not necessarily a permanent improvement in the underlying rental value of the building. Some of the payment may simply recover the landlord’s expenditure on partitions, furniture and equipment whose useful life is shorter than that of the office itself. The meaningful comparison is the rent actually retained after incentives, the full period of vacancy and fit-out works, finance and maintenance costs, and the likely expense of refreshing the space for another tenant. A speculative fitting-out programme therefore has an investment life beyond the first leasing deal; whether the original specification remains useful at the second letting can be as important as the premium obtained at the first.
For an occupier, the calculation runs in the opposite direction, and there is no universal answer as to which model suits a given business best. Fitted space offers less initial capital deployed into a leased asset the occupier does not own, a faster move with less internal project-management burden and greater certainty about the workplace being acquired. Conventional space still suits occupiers who genuinely need a bespoke layout, strong branding or specialist facilities, want full control over the specification, or are taking a sufficiently long lease to make their own investment worthwhile. A fitted office is not necessarily the cheaper choice over the whole term, particularly if the rent reflects a fit-out whose arrangement or quality the occupier would not have chosen. The initial saving has to be considered alongside the continuing cost and usefulness of the finished space.
What this means for how a letting is structured today
The practical effect of this shift is that a growing share of office lettings resemble a product transaction as much as a conventional lease negotiation. Landlords are increasingly offering a finished workplace rather than granting rights over a largely unfinished floor, which changes what agents need to advise on, what prospective tenants need to inspect and how owners think about future refresh and reuse. Furniture, partitions and equipment introduce questions that matter less in a conventional Cat A letting: who owns them, who maintains or replaces them, what can be altered, and which items must remain when the lease ends. The RICS Code for Leasing Business Premises in England and Wales reinforces the need for clarity over repair, alteration and reinstatement obligations, although the allocation in any fitted letting depends on the agreed terms. For the landlord, the continued usefulness of the installation may depend on those terms as much as on the original design. This is not a story about flexible or serviced office operators taking share from conventional leasing — it is a change happening within the conventional leasing model itself, as landlords absorb a category of capital risk that used to sit almost entirely with the tenant.
