Office utilisation across the UK has settled at 66%, down from the long-standing 80% benchmark that landlords and businesses used for decades. That figure, from a 2025 British Council for Offices (BCO) report, isn’t a temporary blip — it’s the new normal. What it means in practice is that roughly a third of the desks in a typical UK office are empty on any given day, yet the rent and energy bills stay the same. The old assumption that you need a fixed desk for every employee no longer holds. Here’s what you actually need to know.
This isn’t about whether the office is dead. It’s about what the office becomes when it’s no longer the default. The BCO report, authored by Nigel Oseland of Workplace Unlimited, draws on sensor data, observation studies, and swipe card records from across the UK. The numbers tell a story of a workplace that’s still very much in use — but used differently. Mid-week peaks are real, with Tuesday to Thursday occupancy hitting 40%, while Mondays and Fridays lag far behind. That pattern alone forces a rethink of everything from cleaning schedules to lease structures. If you’re running a business or managing property, the question isn’t whether people will come back. It’s whether you’re paying for space you don’t need.
What the Shift in Office Utilisation Actually Means for UK Businesses
The core concept here is utilisation rate — the percentage of available desks actually occupied at a given time. For decades, the industry standard was 80%. That number was built on an assumption of fixed, daily attendance. The BCO report makes clear that benchmark is no longer fit for purpose. The new figure of 66% reflects a hybrid model where people come in for specific purposes — meetings, collaboration, training — rather than because a contract says they must.
What I tend to notice when talking to business owners is that many still think in terms of headcount per desk. That model is what’s changing. If you’re planning a lease renewal or a fit-out, the old ratios won’t save you money. The new ones might.
Why the Old Office Model Costs More Than You Think
The financial implications of a 66% utilisation rate are straightforward: you’re paying for space you don’t use. But the hidden costs go deeper. Energy bills, cleaning contracts, business rates, and maintenance are all calculated on total square footage, not actual occupancy. If your office is 30% empty on average, you’re overpaying for utilities by roughly the same margin.
Take a regional office outside London, where the BCO data shows desk utilisation runs about 7% higher than in the capital. That sounds like good news, but it still means nearly a third of desks sit idle. In London, where rents are highest, the gap is even wider. Finance and legal sectors show above-average utilisation, which makes sense — those industries have historically required more in-person presence. But even there, the pattern of mid-week peaks and quiet Mondays holds.
There’s also a sustainability angle that’s easy to overlook. A half-empty building still needs heating, cooling, and lighting for the whole floor. The BCO report argues that low-density, high-utilisation offices are more sustainable than high-density, underused spaces. In other words, it’s better to have a smaller, well-used office than a large one that’s mostly empty. That’s not just an environmental point — it’s a cost point too.
One thing I’d weigh up here is whether your current lease allows for subletting or downsizing. Many commercial leases in the UK are structured around fixed terms with limited flexibility. If you’re locked into a five-year lease on a floor you only half-use, the wasted cost isn’t just theoretical — it’s a line item on your P&L every month. For businesses looking to manage this, a business advice service can help clarify lease obligations and renegotiation options.
Where Businesses Get the Post-Pandemic Office Wrong
Treating utilisation as a return-to-office problem
The biggest mistake I see is framing this as a battle over attendance. Mandating five days a week doesn’t change the fact that people work differently now. The BCO data shows that even in sectors with above-average utilisation, the mid-week pattern persists. Forcing people back doesn’t fill Monday desks — it just creates resentment. The real question is what the office is for, not how many bodies are in it.
Ignoring the Tuesday-to-Thursday spike
If 40% of your workforce shows up Tuesday through Thursday, but only 20% on Monday and Friday, your space planning needs to account for that. Some businesses try to squeeze everyone into the same floorplate on busy days, leading to overcrowding and noise complaints. Others keep the full floor open all week, wasting energy and cleaning costs on quiet days. The BCO report suggests providing services through incremental modular units and mothballing floors or deactivating surplus toilets and lifts during low-occupancy periods. That’s a practical fix, but it requires a mindset shift.
Assuming one size fits all sectors
Corporate occupiers show 13% higher desk utilisation than the public sector. Regional offices outperform London by about 7%. Finance and legal sectors lead the pack. If you’re running a tech startup in Manchester, your office needs will look nothing like a law firm in the City. The mistake is copying what someone else does without looking at your own data. Swipe card records, booking system analytics, and simple observation can tell you exactly how your space is used. Most businesses don’t bother collecting that information.
Overlooking the cost of underused common areas
It’s not just desks that sit empty. Meeting rooms, breakout spaces, and kitchens are often designed for peak capacity but used at a fraction of that. If your boardroom is booked twice a week but heated and cleaned every day, that’s a cost you can reduce. The BCO report’s recommendation to mothball floors or deactivate services applies to common areas too. A space planning guide can help you map actual usage against floor plans before making changes.

How to Reimagine Your Workspace for the New Normal
Audit your actual usage before making changes
Before you redesign, sublet, or break a lease, you need hard data. The BCO report used sensor data, observation studies, and swipe card records. You can do the same on a smaller scale. Track who comes in, when, and what they do. Look at booking systems for meeting rooms. Walk the floor at different times of day. The goal is to understand your real utilisation rate, not the one you assume. Once you have that number, you can decide whether to downsize, reconfigure, or share space.
Design for mid-week peaks, not daily averages
If Tuesday to Thursday is your busy period, plan for it. That might mean having enough desks for 40% of your headcount, not 100%. It might mean creating bookable zones that open and close based on demand. The BCO report’s suggestion of incremental modular units is worth considering — think movable walls, furniture on casters, and technology that lets people plug in anywhere. On quiet days, you close off sections and save on energy and cleaning. On busy days, you open everything up.
Rethink the lease, not just the layout
Commercial leases in the UK are notoriously inflexible, but the market is shifting. More landlords are offering shorter terms, break clauses, and serviced office arrangements. If you’re locked into a long lease, look at subletting surplus space or negotiating a surrender. The BCO data gives you evidence: if you can show that your utilisation rate is 66% and your lease is based on 80%, you have a case for restructuring. For complex lease negotiations, a business law consultation can clarify your options.
Invest in remote-work infrastructure, not just office perks
The office isn’t dying, but it’s becoming one option among several. If your team works from home two or three days a week, they need the tools to do that well. That means secure VPNs, collaboration software, and clear policies around data security. A business VPN service can protect company data when employees connect from home or coffee shops. The office then becomes a place for what can’t be done remotely — face-to-face meetings, hands-on training, and spontaneous collaboration.
Plan for the future of hybrid work
The BCO report is clear that this shift isn’t temporary. Nigel Oseland, the report’s author, put it this way: “This shift in utilisation isn’t a setback. It’s a signal.” Organisations that treat it as a signal — rather than a problem to be solved — will come out ahead. That means thinking about how your space needs might change over the next three to five years. If you’re designing a new office, build in flexibility from the start. If you’re stuck with an old one, start planning your exit or reconfiguration now. The businesses that adapt fastest will be the ones that treat the office as a tool, not an anchor.

The Office Isn’t Dead — But the Old Lease Probably Is
The 80% utilisation benchmark is gone, and it’s not coming back. The BCO report makes that clear. What replaces it isn’t a single number but a set of choices: how much space you need, when you need it, and what you’re willing to pay for the empty parts. The businesses that treat this as a design problem rather than a cultural battle will save money, reduce waste, and create spaces that actually work for the people using them. My advice is to start with your own data. Count the desks, track the swipes, and look at the energy bills. The numbers will tell you what to do next.
