If you’re a small business owner looking for commercial space in the UK right now, you’re entering a market that looks very different from just a few years ago. Prime rental growth has been running higher than normal across all sectors, but that’s not because demand is booming — it’s because there simply isn’t enough new space being built. According to Savills’ latest outlook, the lack of development activity, combined with steady tenant demand, has pushed rents up in the best locations while leaving secondary spots struggling to find takers. That means the choice you make about where to rent isn’t just about price — it’s about whether the space you pick will hold its value and attract customers or employees over the next few years.
I’ve been watching the UK commercial property market for years, and what I keep coming back to is this: the gap between prime and secondary is getting wider, and it’s happening fast. Tenants are more selective than I’ve ever seen them. A great building in a so-so location is now much harder to let than it would have been in a normal cycle. That’s not just a landlord problem — it’s a business problem. If you sign a lease in the wrong spot, you could be stuck with a space that’s hard to sublet, hard to sell, and hard to grow out of. Here’s what you actually need to know.
What prime rental growth actually means for your business
When I say prime rental growth is higher than normal, I’m not talking about a small bump. Over the last five years, rents on the best commercial spaces have risen steadily, and the main reason is that developers simply aren’t building enough. In the key regional city office markets, there were almost no development starts in 2025. That’s not a blip — it’s a structural shortage. And when supply is tight, landlords with the best properties hold the negotiating power.
What this means for you is straightforward: if you need a well-located space, you’re going to pay more for it, and you’ll have less room to negotiate on terms. But there’s a flip side. The same supply shortage means that if you do secure a prime lease, your rental commitment is likely to hold its value — or even increase — over the term. That’s not true for secondary spaces, where vacancy is higher and rents are softer. My advice? Be honest about what you actually need. A flashy postcode isn’t worth it if your customers are online and your team works remotely. But if footfall or client-facing presence matters, skimping on location to save a few hundred pounds a month could cost you far more in lost business.
Why the gap between prime and secondary is growing
This is the trend I think most small business owners underestimate. According to CBRE’s UK Real Estate Market Outlook 2026, the occupational outlook is distinctly sector-dependent, and supply dynamics will continue to shape the market with demand firmly focused on high-quality, well-located spaces. That’s a polite way of saying that mediocre spaces in mediocre locations are getting left behind.
Take retail as an example. Vacancy rates in dominant locations are down to cyclical lows, and that’s delivering real rental growth. But outside those top-tier spots, retailers are still struggling. Many multi-site operators are optimising their portfolios — which often means closing underperforming stores. If you’re renting a roadside retail unit, the difference between a prime pitch and a secondary one can be the difference between thriving and just surviving. The same pattern holds for offices. In central London, the bulk of new development is happening outside the Core, but the bulk of tenant demand is inside it. That mismatch means you could end up in a shiny new building that’s hard to staff because nobody wants to commute there.
What I’d do in your shoes is spend serious time on location analysis before you even look at specific properties. Walk the area at different times of day. Talk to neighbouring businesses. Check transport links and planned developments. A thorough location assessment is the single best investment you can make before signing a lease.
Where businesses get tripped up in the current market
I see the same mistakes repeating, and they’re almost always rooted in assumptions that no longer hold. Here are the ones that matter most right now.
Assuming a low headline rent means a good deal
A cheap rent on a secondary space can look tempting, especially when you’re watching your startup costs. But the data tells a different story. In both retail and logistics, a high headline vacancy rate can hide substantially lower availability in the prime schemes. That means the cheap space you’re looking at might be cheap for a reason — and it might stay cheap because nobody else wants it. If your business relies on passing trade, visibility, or easy access for staff, a low rent in a dead spot is no bargain. You’re better off paying more for a location that works than saving money on one that doesn’t.
Ignoring the cost of debt and how it affects your landlord
This one is less obvious, but it matters. Falling interest rates and greater competition between lenders mean the cost of debt is coming down. That’s good news if you’re borrowing, but it also affects your landlord’s position. If your landlord has expensive debt coming up for renewal, they may be more motivated to negotiate on rent or terms to keep a good tenant. On the other hand, if they’re sitting on cheap fixed-rate debt, they can afford to hold out for a higher rent. Understanding your landlord’s financial position — or at least asking the right questions — can give you leverage you didn’t know you had.
Overlooking the data centre and logistics squeeze
This might not seem relevant if you’re not in tech or warehousing, but it affects the whole market. The AI and cloud-driven boom in demand for data centre space has been the standout story of 2025. Logistics developers are already being outbid for key data and power-enabled sites. That means less land available for new warehouses and distribution centres, which pushes up rents in the logistics sector and squeezes availability. If your business needs storage or distribution space, you need to act early and be prepared to commit. Waiting for the perfect deal could leave you with no deal at all.

The market is shifting, but that doesn’t mean you should sit on your hands. Here’s a practical guide to making the right move in 2026.
Start with a location audit, not a property search
Most people start by looking at available spaces. That’s backwards. Start by defining what your business actually needs from a location. Is footfall critical? Do you need to be near a motorway junction? Is public transport access a dealbreaker for your staff? Once you have a clear brief, map the areas that meet your criteria. Then look at what’s available. This approach saves you from falling in love with a property that’s in the wrong place. If you’re considering a roadside retail unit, specific location factors like visibility, parking, and passing traffic volume can make or break your business.
Negotiate with the supply shortage in mind
In a market where prime space is scarce, you can’t expect huge rent reductions. But you can negotiate on other terms. Ask for a rent-free period at the start of the lease. Negotiate a break clause after two or three years. See if the landlord will contribute to fit-out costs. These concessions can be worth tens of thousands of pounds and don’t affect the headline rent, which means the landlord can still report a strong rental figure to their investors. If you’re unsure about the legal language in your lease, it’s worth getting a tenant landlord lawyer to review the terms before you sign.
Plan for higher operating costs in retail
Retailers are facing higher operating costs in 2026, and Savills expects rental growth to soften as a result. If you’re in retail, factor in not just the rent but also business rates, service charges, and energy costs. A space that looks affordable on rent alone might be unaffordable once you add everything up. Build a full cost model before you commit, and leave yourself some headroom for unexpected increases.
Watch the emerging trends — especially data centres and AI
This is the forward-looking piece that most small business guides miss. The AI-driven demand for data centre space is reshaping the commercial property market in ways that will ripple out for years. Data centres consume huge amounts of power and land, and they’re outbidding logistics developers for sites. That means less land for warehouses, which pushes up logistics rents, which eventually feeds into the cost of goods for every business. If you’re in e-commerce, retail, or manufacturing, this trend will affect your supply chain costs. It’s worth monitoring even if you’re not in the market for a lease right now.
- 1Define your location criteriaMap out what your business needs from a location before you look at any properties. Consider footfall, transport, parking, and nearby amenities.
- 2Research the local marketCheck vacancy rates, recent rental transactions, and planned developments in your target area. Use data from Savills and CBRE reports to understand supply dynamics.
- 3Negotiate beyond the headline rentFocus on rent-free periods, break clauses, and fit-out contributions. These can be more valuable than a small rent reduction.
- 4Get legal advice on the leaseHave a property lawyer review the lease terms, especially break clauses, repair obligations, and service charge provisions.
- 5Build a full cost modelInclude rent, business rates, service charges, energy, insurance, and fit-out costs. Leave headroom for increases.

Your next move in a shifting market
The UK commercial rental market in 2026 rewards preparation and penalises haste. Supply is tight in the best locations, rents are rising, and the gap between prime and secondary is widening. But that doesn’t mean you can’t find a good deal — it means you need to be smarter about where you look and how you negotiate. Start with your location criteria, build a full cost model, and don’t be afraid to ask for terms that protect your flexibility. The businesses that thrive in this market will be the ones that treat their lease as a strategic decision, not a box to tick.
