If you’re looking to lease tech park space in the UK right now, you’re entering a market where demand is outstripping supply at a record pace. In 2025, take-up of data centre space in London exceeded new supply, and 2026 is forecast to be the fifth consecutive year where that happens. That means the usual advice about taking your time and negotiating hard doesn’t fully apply anymore — speed and preparation matter more than ever.
I’ve been watching the UK commercial property market for years, and I’ve never seen a squeeze quite like this one. The combination of AI demand, limited power availability in established clusters, and a government pushing hard for AI growth zones means that anyone looking for tech park space needs to think differently. You can’t just browse listings and pick the cheapest option. You need to understand where power is available, which partners can deliver quickly, and what type of lease structure actually works for your business. Here’s what you actually need to know.
What Leasing Tech Park Space Actually Means
The most important thing to understand is that you’re not just renting square metres. You’re buying into a power allocation, a connectivity setup, and a timeline. When CoreWeave’s European boss said speed is the greatest currency in the AI market, he was explaining why his company sub-leases space inside existing facilities rather than building new ones. Building from scratch takes two to three years. Sub-leasing can take months.
For most businesses, the choice comes down to whether you need space immediately or can afford to wait. If you need it now, sub-leasing from a neocloud or taking space in a shared office with high-speed internet is your best bet. If you have time, a science park or incubator programme might offer better long-term value. What I’d do is start with the timeline first — work backwards from when you need to be operational, then figure out which type of space fits that window.
Why the Squeeze on Tech Space Affects Your Business
The numbers tell a clear story. In 2025 and 2026 combined, new supply in London is forecast at 373MW — more than double the 147MW delivered in the previous two-year period. Yet even with that record growth, take-up will still exceed new supply for the fifth year running. That means every available space is being fought over.
Consider a scenario where your business needs 500kW of compute capacity to run an AI workload. If you try to build your own data centre, you’re looking at 2028 at the earliest. If you lease space in a science park that has a university link, you might get subsidised rent but limited power. If you sub-lease from a neocloud operating in London Docklands or Crawley, you could be running in three months — but you’ll pay a premium.
There’s also a regional dimension worth noting. London accounts for over 80% of UK data centre supply. After that, Newport and Cardiff make up 9%, and Manchester just 2%. If your business doesn’t need to be in London, the AI growth zones in Culham, Teesside, Newcastle, and Wales could offer better availability and lower costs. The government is incentivising development in those areas with capacity targets of up to 500MW per zone.
What I notice is that businesses often underestimate how long the search takes. They assume they can find space in a month and move in the next. In this market, you need to start looking six to twelve months before you actually need to be operational. The ones who wait until the last minute end up paying over the odds for whatever is left.
Where Businesses Get Tripped Up
I’ve seen the same mistakes come up again and again. Here are the ones that cost the most time and money.
Underestimating Power Requirements
New data centre developments are now being planned with AI workloads in mind, which means higher power densities and increased floor loadings are required. If you lease space in an older facility that wasn’t designed for AI, you might find you can’t actually run your equipment. Always ask for the power density per rack and the total available capacity before signing anything.
Ignoring the Sub-Lease Option
Many businesses assume they need to build or lease directly from a landlord. But neoclouds exist precisely to solve the speed problem. CoreWeave operates two data centres in England — one in London Docklands with Digital Switch and one in Crawley with Digital Realty — and is partnering on a third in Lanarkshire with DataVita. All of these are sub-lease arrangements. If you need compute fast, sub-leasing from a neocloud is often the quickest route.
Overlooking Incubator and Accelerator Programmes
There are around 400 incubator programmes and 300 accelerator programmes operating in the UK. Around one third of incubators focus on digital and fintech. Most charge fees or rent, but these are often subsidised by universities or public funding. If your business qualifies, you could get space at a fraction of the market rate plus access to mentorship and funding. Accelerators tend to offer direct funding in exchange for equity (typically under 10%), so they’re better suited to growth-stage companies.
Misunderstanding Service Charges and Fit-Out Costs
Tech park leases often include service charges for shared infrastructure — security, maintenance, common areas. These can add 20–30% to your base rent. On top of that, you may need to fit out the space to handle your power and cooling requirements. A tenant service charge guide can help you understand what’s included and what isn’t. Always get a full breakdown in writing before you commit.

| Space Type | Typical Duration | Key Feature |
|---|---|---|
| Incubator | Ongoing, subsidised | University or public funding, ~1/3 focus on digital |
| Accelerator | 3–12 months | Growth-driven, equity funding (under 10%) |
| Science Park | Long-term lease | University links, knowledge-based businesses |
| Shared Office | Flexible | 24-hour access, high-speed internet, meeting rooms |
What I’d flag as the most consequential mistake is the power one. I’ve seen businesses sign a five-year lease only to discover six months in that they can’t get the power they need. By then, they’re stuck. Always get a power feasibility study done before you sign, and make sure the lease includes a break clause if the power isn’t delivered as promised.

Start With Your Timeline and Power Needs
Before you look at a single property, write down two numbers: the date you need to be operational, and the power capacity you need in kilowatts. If you need to be running in under six months, your only realistic option is sub-leasing from a neocloud or taking space in a shared office that already has high-density power. If you have 12 months or more, you can consider science parks or even new-build developments in AI growth zones.
For power, remember that new developments must cater for higher power densities and increased floor loadings. If your equipment requires more than 10kW per rack, older facilities won’t work. Ask every landlord for their maximum power density per rack and their total available capacity. If they can’t give you a straight answer, move on.
Evaluate the Different Space Types
Each type of tech park space serves a different purpose. Science parks, of which there are approximately 100 in the UK, are designed for knowledge-based businesses and usually have formal links with universities. They’re good for R&D-focused companies that want access to academic talent. Incubators and accelerators are better for early-stage startups that need mentorship and funding alongside space. Shared offices work well for small teams that need flexibility and don’t require high power densities.
If you’re unsure which type fits, I’d start with a commercial property rental checklist to make sure you’ve covered the basics. Then narrow down by power requirements and timeline.
Negotiate the Lease With Power and Break Clauses in Mind
Standard commercial leases don’t always account for the specific needs of tech tenants. You need to negotiate for three things: a power guarantee (the landlord commits to delivering a minimum power capacity), a break clause if that power isn’t available within a set timeframe, and clarity on who pays for fit-out and upgrades. Service charges are another area where costs can balloon. A tenant service charge budget guide can help you spot hidden costs.
If the lease is complex — and most tech park leases are — it’s worth getting a property lawyer to review it. A tenant landlord lawyer can help you understand your rights around evictions, lease terms, and dispute resolution. The cost of legal review is small compared to the cost of a bad lease.
Consider AI Growth Zones for Future-Proofing
The UK government is actively promoting AI growth zones in Culham, Teesside, Newcastle, and North and South Wales. These zones are designed to support capacity of up to 500MW each. If your business is planning for significant growth, locating in one of these zones could give you access to power and space that simply isn’t available in London. The trade-off is that you’re further from the main talent pool and connectivity hubs. But for AI workloads that don’t require physical proximity to London, the cost savings could be substantial.
What I’d do is look at the AI growth zone map and see if any of those locations align with where your team lives or wants to be. If you can make it work, you’ll likely find better terms and faster build times than in the London area.
