Warehouse Construction in 2027: The Trends That Actually Matter

Most "trends" articles are a list of things you already know. Automation is growing. Sustainability matters. E-commerce is big. None of it helps you decide anything.

This one is different. Below are the trends shaping warehouse construction going into 2027, based on where the UK market actually is right now, and what each one means for a decision you might be facing. The through-line is simple: with new space scarce and older buildings falling behind, 2027 is a year where upgrading what you have often beats waiting for something new.

These are forecasts and current readings, not certainties, so treat them as a steer and check the detail before you commit.

1. New space is scarce, and getting scarcer

This is the big one, and it changes the maths for everyone.

The amount of new warehouse space being built has collapsed. The volume under construction has fallen by around 65 per cent from its 2022 peak, and completions are running well below the long-term average, with limited new supply expected through 2027. At the same time, demand for space is still strong, running above pre-pandemic levels.

Less new space plus steady demand means one thing: good space is hard to find, and it will stay that way.

What it means for you. If you need more space in 2027, waiting for a brand new building may not be realistic. Extending your current warehouse, or refurbishing existing stock, is often faster and more certain than chasing scarce new supply. Our guide on whether to refurbish, rebuild or relocate walks through that call.

2. Old warehouses are falling behind

There is a clear split in the market. Occupiers are moving into modern, efficient buildings and leaving older ones behind. Vacancy in second-hand warehouses has reached a ten-year high, while good quality space stays tight and its rents keep climbing.

In plain terms, an older warehouse is at growing risk of becoming hard to let. Not because there is no demand, but because demand has moved to better buildings.

What it means for you. If you own an older warehouse, the risk is obsolescence. The fix is to bring it up to standard: better energy performance, more height where possible, a stronger floor, better power. A well-judged refurbishment can move a tired building back into the bracket occupiers actually want.

3. Energy performance becomes make-or-break

Energy has shifted from a nice-to-have to a deciding factor, for three reasons at once. Occupiers now want efficient buildings with low running costs. Energy and network costs are rising. And the rules are tightening.

The current legal minimum is EPC E, and the Government intends to require EPC B from 2031 for commercial buildings over 1,000 square metres, which is most warehouses, though that is still a proposal rather than law. Either way, the direction is set.

What it means for you. Improving a warehouse's energy performance is now both a compliance job and a lettability job. The measures that lift an EPC, like insulation, LED lighting, better heating and solar, also cut the occupier's bills, which makes the building easier to let. Our MEES and EPC guide covers this in detail. Leaving it until 2030 is leaving it too late.

4. Power is the new planning constraint

Here is a trend that is not talked about enough. Getting enough electrical power to a site is now one of the biggest constraints on what you can build.

Grid connection lead times vary by more than a decade across different parts of the country, and network capacity is a genuine bottleneck. Anything power-hungry, whether automation, cold storage or EV charging for a fleet, needs power that is not always quickly available.

What it means for you. If your 2027 plans need more power, start that conversation with the network operator very early, before the design is fixed. On some sites, power availability will shape what is possible more than planning does. It is the item most likely to hold up an otherwise straightforward project.

5. Buildings are being built for automation, even before it arrives

Automation keeps advancing, but the practical point for construction is what it demands of the building. Automated storage systems need flatter, stronger floor slabs, more power, and often more height than a traditional warehouse.

You do not have to be automating today for this to matter. Building or refurbishing so the building could take automation later protects its value, because it keeps the building attractive to the occupiers who will want it.

What it means for you. When you build or refurbish, it is worth designing the floor slab and the power supply with future use in mind, not just today's operation. Retrofitting a floor flat enough for automated systems into a working building is difficult and expensive. Getting it right first time is not.

6. Land scarcity is pushing space upward and into cities

Where land is scarce and expensive, particularly in and around London, two things are happening. Last-mile delivery is driving demand for warehouse space close to where people live, and multi-storey warehouses are starting to appear as a way to get more out of a small, high-value plot.

What it means for you. If you are a developer working in a tight urban market, the old assumption of a single-storey shed on a large plot does not always hold any more. It is worth looking at what a site can deliver across more than one level.

7. Lease and planning changes worth watching

A few background shifts that landlords and developers should have on their radar for 2027:

• A ban on upwards-only rent reviews in commercial leases is expected to take effect in early 2027, which changes how future lease income works.
• Planning reform continues, with the aim of making commercial development faster and more consistent across England.
• Biodiversity Net Gain still applies to any new footprint, so factor it into extensions and new builds.

None of these is a reason to act on its own, but together they shape the environment you are building in.

A note for the team: a real example would lift this. For instance an older warehouse refurbished to a modern, lettable standard, or an extension delivered when new space was not available. A genuine project shows these trends playing out, rather than just describing them.

What it adds up to for 2027

Put the trends together and a clear picture emerges. New space is scarce. Older buildings are losing ground. Energy performance and power supply are now central, not side issues. And costs to build remain high.

For most warehouse owners, that points the same way: the building you already have is an asset worth investing in. Upgrading, extending or future-proofing existing stock is, for many, the smartest move available in 2027, and often more achievable than competing for the small pool of new space.
