Death of the high street turns retail parks into hot property

For years, Britain’s retail parks were treated as functional afterthoughts: practical sheds on ring roads, useful for buying a sofa, a tin of paint, or a replacement tumble dryer, but rarely celebrated. They were the places people went with a purpose, not the places they lingered. That hierarchy has been upended. As town centres wrestle with vacancies, high costs and changing shopping habits, the once-unloved retail park has become one of the most fiercely contested formats in British bricks-and-mortar.

Landlords and agents describe a market in which space is scarce, especially for larger units, and occupancy levels are close to full. British Land, one of the biggest owners in the sector, puts its retail parks at about 99 per cent occupied. Across the wider retail warehousing market, vacancy stood at 4.8 per cent at the end of 2025, according to Knight Frank, the lowest level on record. That is not the profile of a declining asset class. It is the profile of something that has become strategically important.

The change is visible in the names on the signage. A decade ago the mix tilted heavily towards DIY, furniture and electricals, categories that suited big boxes and car boots. Those retailers remain, but they no longer define the offer. Discount chains have been the most obvious vanguard. Aldi and Lidl are hunting for sites; B&M and Home Bargains are still expanding. Alongside them have come fashion brands, chemists, gyms and leisure operators. Knight Frank points to Superdrug and Mountain Warehouse among the biggest takers of retail park space last year, while PureGym and The Gym Group continue to roll out new locations.

That breadth matters because it reframes what a retail park is for. If it is simply a destination for bulky goods, demand is bounded by a handful of categories and by replacement cycles. If it becomes a place where shoppers can pick up groceries, collect parcels, return online purchases, buy a winter coat and then go to the gym, it starts to look less like a specialist out-of-town annex and more like a modern form of neighbourhood centre, designed around the car and the practicalities of contemporary life.

The economic logic is not subtle. Trading from a retail park is typically cheaper than trading from a prime high street pitch. Rents are often lower for the space you get, units are straightforward to fit out, and operations can be run with a kind of industrial efficiency. Stephen Springham of Knight Frank describes these parks as fit-for-purpose units in convenient locations, and argues the fundamentals remain compelling: in simple terms, it is tangibly cheaper to do business there than in a town centre.

Yet cost is only part of the story. The deeper driver is that retailers are reappraising the relationship between stores and online shopping. For a period, the industry treated physical space as a legacy burden and digital as an unalloyed good. The pandemic turbocharged that mindset, but it also exposed the hard arithmetic behind home delivery and returns. Moving a package to a front door is expensive. Processing returns, particularly in apparel, can be cripplingly costly. What looked like sleek growth on the top line could be messy and margin-thinning underneath.

Retail parks fit neatly into a more pragmatic model, in which shops are not merely showrooms or brand theatres but working parts of a distribution system. Matt Reed, British Land’s head of retail parks, argues that getting a customer into a store is often far cheaper than fulfilling an online order to the home, and that once people cross the threshold they tend to buy more. Out-of-town parks, with extensive free parking and easy access from major roads, are designed for the kind of trip that stitches those behaviours together: collect an order, return another, and do the rest of the shopping in the same stop.

In an era when retailers talk increasingly about omnichannel, the unglamorous virtues of a steel-frame unit become an advantage. A shop that is essentially a box can be adapted. Space for click-and-collect can be carved out without the structural constraints of older high street buildings or enclosed shopping centres. Returns processing can be integrated into the store in a way that is cheaper to implement and easier for customers to use. That operational flexibility is not an aesthetic point. It can be the difference between a channel strategy that works on a PowerPoint slide and one that works in the accounts.

Retail parks also benefit from clustering effects. A senior retail source notes that operators can share costs, draw on existing footfall and exploit the fact that parking is guaranteed. If a customer is already driving to one anchor retailer, they are likely to visit others. On a fragile high street, footfall can be a gamble; on a well-let retail park, it is at least partially inherited. This is why, as Springham puts it, retailers increasingly trade where they make the most money. The park is not simply cheaper space; it is space configured to capture a reliable kind of custom.

There is, however, a structural tension behind the boom: demand is colliding with a constrained supply pipeline. Knight Frank research suggests that only 21 retail warehouse schemes are likely to be delivered before 2033, adding about 2.7 million sq ft over eight years. That figure looks modest when set against the pace at which retailers have been taking space: roughly 7.5 million sq ft of retail warehouse space was absorbed in 2025 alone. Even allowing for year-to-year variation, the imbalance implied by those numbers is clear. One side of the equation is moving faster than the other.

Part of the constraint is geography and land economics. Britain is a small, densely used country with competing priorities for development land. Sites suitable for sizeable, accessible retail warehousing are not infinite. But the more binding constraints are political and financial. Planning rules intended to protect town centres make it difficult to justify out-of-town retail. Higher construction costs and higher borrowing costs make new schemes harder to underwrite. Reed’s remark that it is currently cheaper to buy a retail park than to build one is telling: when replacement cost exceeds asset value, the market signals that new supply will be slow.

Retailers themselves complain that the planning system has become more onerous and slower. One senior source says that applications which once took around 13 weeks can now take more than twice as long, and in some cases up to two years. Time, in property, is money. A prolonged process raises risk and pushes up the cost of capital, which in turn makes marginal projects unviable. The irony is that a system designed to shepherd retail back into town centres may inadvertently starve the market of the kind of modern space retailers can operate profitably, leaving them to compete over the limited stock that already exists.

Where development does happen, it is more likely to be smaller and anchored by a supermarket rather than the sprawling parks associated with the 1990s. That shift reflects not only planning pressures but changing consumer patterns. The vast out-of-town retail park was a product of a particular era: rising car ownership, cheap land, and a retail model built around large-format specialists. The next generation may be more hybrid, combining food retail with a few complementary units rather than attempting to recreate an entire town centre on a bypass.

Even the existing stock is not safe from competing land uses. Housing developers are increasingly interested in retail park sites, particularly in London, where residential values can make redevelopment tempting. For local authorities under pressure to meet housing targets, a big plot with good transport links can look like an opportunity. For retailers and landlords, it is a threat to scarce trading space. A retail park can be full today and gone tomorrow if the land is worth more as flats, and that possibility becomes more acute the closer you get to the capital and other high-demand cities.

The debate is often framed as a contest between town centres and out-of-town retail, as if one must be sacrificed for the other. Springham argues that thinking in binaries risks a robbing-Peter-to-pay-Paul outcome, penalising retail warehousing in an effort to revive the high street. The reality is more complicated. The high street is not suffering solely because of retail parks; it is suffering because of business rates, changing consumer habits, a legacy oversupply of shops, and the migration of many categories online. Forcing retailers into uneconomic premises will not reverse those structural forces. It may simply accelerate store closures and reduce investment.

At the same time, it would be complacent to treat the retail park renaissance as an unproblematic win. A format built around driving, with expansive surface parking, sits awkwardly with climate ambitions and efforts to reduce car dependency. Retail parks can be difficult to reach without a vehicle, which raises questions about equity and access. They can also drain activity from town centres if they become the default place for everyday purchases. The challenge for policymakers is to reconcile the economic success of a format that shoppers clearly value with broader goals about place-making, transport and community life.

For retailers, the immediate concern is more prosaic: securing space. As availability tightens, competitive behaviour intensifies. Landlords report retailers paying premiums for future space or attempting to buy units years before they become vacant. That is a sign not only of confidence but of anxiety. When a retailer is willing to lock up capital simply to control a location, it suggests a belief that the right kind of physical footprint will be hard to assemble later. It is also a reminder that property strategy has become inseparable from retail strategy. In a market shaped by fulfilment costs and returns, location is not just about catchment; it is about logistics.

Scarcity changes the balance of power. If vacancy is low and supply growth is limited, landlords can be more selective about tenants, and rents can rise. That may be manageable for strong operators, but it can squeeze the very formats that have helped drive demand, particularly discounters whose proposition relies on tight cost control. The success of retail parks has been partly built on offering value to customers; if property costs inflate too far, the economics could begin to shift. A retail park can remain busy while the margin structure underneath becomes less forgiving.

There is also a question about what kind of retail mix emerges when parks are full and competition is fierce. The temptation is to prioritise covenant strength and the ability to pay, which can produce a homogenised lineup of national chains. Yet part of the appeal of town centres has historically been variety. Retail parks are already more standardised by design. If the boom results in parks that look increasingly alike from one town to the next, the format may reach a point of diminishing returns, particularly as consumers seek experiences that feel less interchangeable.

Still, the direction of travel is clear. The resurgence of retail parks is not simply nostalgia for shopping trips with a trolley and a boot full of flat-pack. It is a response to how modern retail works: the blending of physical and digital, the need to manage fulfilment costs, and the desire to make shopping efficient for customers whose time is scarce. Retail parks have been quietly rebranded from out-of-town sprawl into practical infrastructure. Their success is rooted in convenience and operational sense, not romance.

The unresolved issue is whether Britain can expand or adapt this infrastructure without undermining town centres or colliding with planning priorities. With only a limited pipeline of new schemes, and with residential redevelopment nibbling at the edges of the existing stock, the market risks the kind of bottleneck Knight Frank describes as a sleepwalk towards a supply crisis. If demand continues to broaden beyond traditional big-box categories, that bottleneck will be felt not at the fringes but at the core of mainstream retail expansion plans, shaping where shops open, how online orders are handled, and what kind of shopping environments British consumers come to treat as normal.
