Sunday Trading Laws: What Applies on Sunday, 30 August?
Standard Sunday Trading Laws (Sunday Trading Act 1994) apply as normal across England and Wales on Sunday, 30 August 2026:
Large Superstores (Over 280 sq metres / 3,000 sq ft): Allowed to open for a maximum of 6 continuous hours between 10:00 AM and 6:00 PM.
Convenience Stores & Forecourts: Exempt from Sunday limits and may open 24 hours or operate standard hours.
Scotland: Sunday trading restrictions do not apply; large stores can open standard weekend hours.
New Price Marking Order Rules: Spotting True Bank Holiday Savings
When browsing supermarket aisles this weekend, shoppers will notice stricter shelf labels due to updated Price Marking Order (PMO) reforms.
Standardised Unit Pricing: Supermarkets are now legally required to display consistent unit measurements (e.g., comparing all items strictly per kg or per litre) rather than mixing grams and kilograms.
Loyalty Price Transparency: Supermarkets using member pricing (such as Tesco Clubcard Prices or Sainsbury’s Nectar Prices) must display the non-member unit price alongside the loyalty discount without giving “undue prominence” to the lower cardholder price.
