If you live anywhere near Wrexham, Rhyl, or Llandudno, you've probably heard the rumors. They spread through local Facebook groups like wildfire every few months. Someone mentions a "reliable source" or a cousin who works in planning, and suddenly everyone is convinced that a massive warehouse filled with rotisserie chickens and five-liter tubs of mayonnaise is finally coming to North Wales.
It’s a bit of a local obsession.
Currently, if you want your Costco in North Wales fix, you are likely trekking over the border to Chester (Sealand Road) or maybe down to Haydock. It’s a long drive. It’s an even longer drive back when you realize you’ve bought a kayak and three 24-packs of sparkling water that barely fit in the boot of your car. For years, the region has been a "dead zone" for the American wholesale giant, despite the clear demand from small business owners and large families across the coast.
The Chester Bottleneck and the Hunt for Land
The Chester branch is basically the unofficial hub for the entire North Wales population. It's packed. On a Saturday afternoon, trying to navigate that car park is basically a combat sport. This congestion is exactly why people keep looking for signs of a new opening further west.
But why hasn't it happened yet?
Costco is notoriously picky about real estate. They don't just want a "big" space; they want a specific alignment of logistics. We are talking about 150,000 square feet of floor space, proximity to a major dual carriageway like the A55, and a catchment area that justifies the massive overhead.
North Wales has plenty of land, but much of it is protected, topographically challenging, or lacks the heavy-duty road infrastructure to support hundreds of HGVs and thousands of shoppers daily. Local councils like Denbighshire and Flintshire are always hungry for the business rates and jobs a warehouse club brings, yet the "perfect" site remains elusive.
What the Planning Applications Really Say
Let's look at the facts. There have been several "near misses." A few years back, rumors swirled around the Northern Gateway site in Deeside. It made sense. It was right on the border, easy access, and plenty of room. However, that space has largely been taken up by housing and other industrial logistics hubs like Amazon.

Then there’s Wrexham.
As Wrexham’s profile rises—thanks in no small part to a certain pair of Hollywood owners—the city has become a much more attractive prospect for international brands. The Wrexham Industrial Estate is one of the largest in Europe. It has the space. But Costco’s model relies on high-visibility retail locations, not just being tucked away in an industrial park where people struggle to find the entrance.
Honestly, the company is quiet. They don't announce "potential" sites. They wait until the ink is dry on the land purchase and the planning permission is uncontested. If you see a headline saying "Costco Confirmed for Rhyl," and it isn't from a major news outlet with a quote from a spokesperson, it’s probably just clickbait based on a speculative property listing.
Why the A55 Corridor is the Only Logical Choice
If a Costco in North Wales ever moves from "internet myth" to "brick and mortar," it has to be on the A55.
Think about the geography.
If you put a store in Bangor, you lose the eastern customers who will just keep going to Chester. If you put it in Queensferry, it’s too close to the existing one. The "sweet spot" has always been somewhere between St Asaph and Abergele. This location would capture the bulk of the coastal population while remaining accessible for those coming up from the Conwy Valley or across from Holywell.
- Access: Needs to be within 5 minutes of an A55 junction.
- Competition: They don't care about Tesco or Asda; they care about where their members live.
- Demographics: They look for areas with high homeownership and a high density of small businesses (trade members).
The logistics of the A55 are a double-edged sword. While it's a great artery for customers, the sheer volume of traffic during the tourist season makes delivery windows a nightmare. No company wants their supply chain stuck in "Black Cat" roundabout traffic for three hours when they have perishables to unload.

The Membership Question: Is it Worth the Wait?
While everyone waits for a local branch, many North Wales residents still pay for the membership. It's a weird quirk of the region. You’ll see the stickers on cars in Caernarvon and Pwllheli.
Is it actually worth the fuel costs?
For a business owner in Colwyn Bay, the savings on bulk cleaning supplies and dry goods usually offset the 45-minute drive to Chester once a month. For a regular family? That's debatable. You have to save a lot on toilet paper to make up for the £15 in petrol and the two hours of your life spent on the road.
People often forget that Costco isn't just a supermarket. It's a petrol station—often the cheapest in the region—an opticians, a tire center, and an insurance broker. A North Wales site wouldn't just sell muffins; it would likely become the cheapest place to fuel up between Cheshire and Holyhead, which would be a massive disruptor for the local independent garages.
Debunking the Latest Rumors
You might have seen the "news" about the old Toys 'R' Us sites or defunct retail parks. Generally, these sites are too small. Costco prefers to build from scratch to their own very specific specifications rather than retrofitting an old building that doesn't have the floor load capacity for their massive racking.
I've looked through the recent local development plans (LDPs) for the major North Wales councils. There is currently no earmarked "Sui Generis" retail use land specifically linked to a warehouse club of this scale. While things can change quickly with a "pre-planning" inquiry, nothing is currently in the formal pipeline.
That doesn't mean it won't happen. It just means it's not happening this Tuesday.

Actionable Steps for North Wales Shoppers
If you are holding your breath for a grand opening in Wrexham or Rhyl, you might want to exhale. But you don't have to miss out on the benefits.
1. Check Online Membership
You don't actually have to go to a physical warehouse to use a membership. Costco.co.uk delivers many of those bulk items—including the Kirkland Signature brands—directly to North Wales addresses. For many, this is a much better option than driving to Chester.
2. Evaluate the "Trade" Status
If you have a side hustle or a small business in North Wales, you can get a Trade Membership. This often allows you to get into the Chester or Haydock stores earlier in the morning, beating the massive crowds that make the journey so stressful.
3. Watch the Wrexham Growth
Keep a very close eye on the expansion of the Wrexham Gateway project. If any city in the region is going to land a major American brand in the next 36 months, it’s Wrexham. The economic momentum there is currently eclipsing the rest of the North Wales coast.
4. Use the Petrol Savings strategically
If you do make the trip to the Chester branch, make sure your tank is empty. The price difference at the Costco pumps often pays for a significant chunk of your annual membership in a single fill-up.
The dream of a Costco in North Wales remains just that—a dream—for now. But as the A55 corridor continues to develop and Wrexham transitions into a proper city economy, the "dead zone" for bulk shopping is getting smaller and smaller. Just don't believe every Facebook post you see until you see the giant red sign being bolted onto a warehouse wall.
