Tesco, the UK's leading supermarket, manages high demand for delivery slots, especially in 2026 amid ongoing online shopping surges. Knowing when new slots are released can mean the difference between stocking up easily or facing delays. Slots typically open based on a predictable schedule tied to logistics and customer patterns.
With Tesco's Groceries app and website updating in real-time, proactive checking is key. This guide breaks down the exact times and tips to snag those elusive slots for your weekly shop.
