The Office Lease Event Guide: What To Do 24 Months Before Your Lease Expires
Agents and solicitors help you execute a lease decision. None of them help you work out what you need. AWA’s 24-month sequence for office lease events.

When it comes to the workplace, everyone is an expert. Your ‘C’ suite leaders have bought, designed or extended their homes, hired interior designers, and managed domestic construction projects. The office building is no different, right?
Well actually no. The office building is more like a complex spaceship with systems and structures that need to deliver on a range of purposes and sustain an organisation through many years, during which the organisation itself is going to change. You can put a house on the market if your domestic situation changes, but you can’t easily escape from a multi-million-pound, multi-year office lease.
Whilst there’s plenty of good advice on office leases from agents, property solicitors, design and build firms and project managers, it tends to cover notice periods, break clauses, heads of terms and dilapidations. Their guidance on what you need, and where, is often overly simplistic. Their advice helps you execute the lease decision, but none of it helps you work out what you need. That’s where we at AWA come in.

The workplace as a strategic business tool
So first off, we treat the workplace as a strategic business tool, not a thing of beauty or an engineering feat: something acquired and designed to produce a business result. If it doesn’t add value, why do you have an office at all?
A lease event is a moment in time at which you can work out what kind of tool the business needs next, but you can only do it by working out the scenarios your business might face and with a strong appreciation of how your current business works.
This guide sets out the sequence that starts with working out what the business is trying to achieve, how it works today, what is changing around it, how much space it needs, and how, eventually, it should be used and managed to help achieve business goals.
Six steps, in order, between 24 months out and the lease event.
- Establish what the workplace is for
- Measure how the current office is actually used
- Understand the employee experience and location fit
- Model the scenarios
- Take a position on AI
- Score buildings against agreed criteria
What should you decide before you start looking for office space?
Decide what you are trying to achieve through the new workplace, before anyone views a building. The first strategic question we ask of your ‘C’ suite leaders is ‘what are you seeking to achieve through the new workplace?’ It’s a simple question and one that requires some deep thought about the organisation’s goals, its external environment, and the way it works.
We’ve found a good way to answer the key question is to issue our Organisational Priorities app to each of the leaders and invite them to allocate 100 points per person to a series of 10 organisational capabilities in relation to their significance to the future success of the business.
Each leader spreads 100 points across 10 capabilities. Added together, the points put the capabilities in rank order, which is the start of the priority list.
The points are allocated in relation to the importance of the specific capability to business success. We play them back in a Vision workshop and reveal all the results to stimulate a discussion that leads to a clear prioritised list of capabilities that the team is committed to.
This priority list can then be used to drive the design, manage ‘value engineering’ tradeoffs, and measure operational performance through time.
How well is your current arrangement working?
Most leaders have a strong opinion on how big their office should be, and almost no data on how it’s actually used. So, to have a meaningful dialogue, our project team captures an evidence-backed picture of the ‘current’ state.
This may include an understanding of existing data surrounding headcount (actuals and forecasts) and attendance, a workplace utilisation study that assesses the use of every space at agreed intervals during the day over a two-week period, along with a thorough review of the space provision from drawings and benchmarks.
Focus groups, interviews, infrastructure reviews, and surveys can help to get a richer picture of the experience employees are sensing on a day-to-day basis. Increasingly an assessment of the cognitive performance of the workforce and the impact of AI are needed to shape the understanding of the here, now and future demands.
The gap between belief and evidence is usually wide. Our Hybrid Working Index 4 (November 2024, 55 offices across 19 countries, 68,000 employees) found average office attendance of 34% against average desk utilisation of 55%.

In terms of location, it’s useful to undertake a ‘Commute Study’. Using specialist software, we’re able to assess the current domestic locations of your workforce and the impact of different locational options. We can quantify the relative change in commuting difficulty along with the sensitivity of a relocation on the likely retention of key skills.
How much space will you need next?
Sizing a 10-year lease on current headcount or next year’s hiring plan is the most common error we see. But we start in a different place. Our question is ‘do you need an office at all?’ and if you do, what do you need it for and what will it be used for.
Advisers associated with organisations that deliver transactions, design services and project management will be reluctant to start in that position. But all these questions need to be considered.
Then there are business changes. What happens when you hire faster than planned and run out of desks? What happens if AI means you need less space? Or if you hire slower and have to pay for empty space?
Scenario modelling is vital. Modelling different business, occupancy and headcount scenarios at twelve months, two, three, four and five years is critical, along with the consideration of strategies that might enable growth without taking on more space.
In today’s world, office attendance is focused on Tuesday, Wednesday and Thursday, with limited attendance on a Monday and barely any on a Friday. The problem is that you may need to size your future office on the peak demand on a Wednesday if you are unable to smooth the demand for space across the week. Call it the peak-day tax: you build for one day and pay for it on all of them.
Also worth remembering that the building will be yours 24 hours a day, 7 days a week, a total of 168 hours. In our experience most organisations are only occupying them for a fraction of that, with genuinely intense use across a narrower window still.
Size the office for Wednesday and every other day pays for the same floor. The building is yours for all 168 hours of the week.
Scenario modelling gives you an understanding of space quantum needed under different circumstances. What happens if the headcount grows, or shrinks? What happens if AI is implemented? What happens if we shift our model to 7 days a week working? What happens if we do more hybrid work? Can we use space at night to serve other geographies?
Model each scenario at twelve months, two, three, four and five years. The spread of outcomes widens with time, and today’s headcount is one line through it.
The next question is what kind of work those people will actually be doing.
What does AI mean for how much space you need?
AI changes the mix of work inside roles before it changes the number of people, and both change the building. We know from our research that AI will automate mechanistic tasks within roles and amplify the cerebral tasks, allowing people to model, write, create, and develop in ways that are more efficient and economically viable than ever before.
Organisations under pressure for margin in steady state business situations will likely use AI to reduce heads and costs. Organisations growing are likely to avoid taking on more people by increasing the productivity of existing workers.
Our approach is to review jobs using our AI role assessment tools, breaking them down into the mechanical, repetitive aspects versus the cerebral tasks. AI, on one hand, is good at repetition and pattern matching, making it easier to automate repetitive tasks.
For instance, a research scientist might be 70% cerebral and 30% mechanistic. A call centre agent might be the other way round. And over time, the cerebral-heavy roles increase while the mechanistic ones may reduce as automation kicks in.
Two example roles. AI automates the mechanistic share of a role and amplifies the cerebral share.
Research scientist
Call centre agent
| Role | Cerebral | Mechanistic |
|---|---|---|
| Research scientist | 70% | 30% |
| Call centre agent | 30% | 70% |
The scale is large enough to change a lease decision. Our AI Impact Report 2026 analysed 412 UK occupations across 18 task categories and models a net cut in UK office demand of around 28 million sq ft at three years, 54 million at five and 90 million at ten.

We expect organisations to shrink in size, but grow in cerebral activity, meaning organisations need to cater for a highly intelligent, knowledge-intensive organisation. AWA’s work on Knowledge Worker Productivity, launched in 2016, now becomes an important asset in defining the future workplace.

Why does a lease decision need 24 months?
Because your options and your leverage both decay as the break date approaches. If your lease expires two years from today, you have enough time to hunt for the best possible buildings and do the best deals. But if your lease expires in six months, your options will be lessened, and you may find your negotiating position weakens as there are fewer buildings available to you.
Both fall as the lease event approaches. By six months there are fewer buildings to choose from and less room to negotiate.
If you’ve undertaken a study to establish your requirements, you will be in a strong position to negotiate your future workplace deal, because you’ll be clear about what your priorities are. You’ll know how much space you’ll need, where you need it, what floorplate sizes would be most appropriate, what’s important, and what’s not.
Then we set up assessment criteria using our studies to create an objective assessment of each building against an agreed set of criteria. These might include a score for location, floorplate size, building services provision, floor to ceiling heights, daylight, amenities in or close to the building, image and so on.
Why is this important? Well just like buying a house, a choice of office can be quite emotional, and some people may like (or even love) a particular building or location and become quite wedded to it. Everyone’s opinion may be different, too. But this lease commitment may well extend beyond the working lives of the people making the decisions, so it’s vital that an objective, unbiased party that has no ‘skin in the game’ is able to give you untainted, unemotional advice. It is the same argument we make about the difference between a workplace consultant and an office designer.
The sooner you can start searches and negotiations, the better, and the better the commercial deal will be.

Frequently asked questions
What is an office lease event?
A lease event is any point at which an organisation can change its property commitment: a lease expiry, a break clause date or a rent review. It is the only moment at which the size, shape and location of the office can be changed.
How far before a lease event should I start planning?
Twenty-four months. That gives you time to establish your requirements, search the market properly, and negotiate from strength. At six months, you choose from what is left.
What is a workplace utilisation study?
An assessment of the use of every space in an office, recorded at agreed intervals during the day over a two-week period, giving you evidence of how much and what kind of space you actually need.
Should I size my next office on my current headcount?
No. Model occupancy and headcount scenarios at twelve months, two, three, four and five years, then size against the range rather than a single number.
Will AI reduce how much office space we need?
On AWA’s modelling, yes. The AI Impact Report 2026 projects a net UK office demand reduction of around 54 million sq ft over five years, phased so that most of it lands later in a typical lease term.
Who should advise on a lease event?
Agents, solicitors, and project managers execute the transaction. Working out what you need is a separate job, best done by a party with no financial interest in the size of the deal.
