Which UK supermarkets closed on Boxing Day 2025?

Multiple outlets reported Aldi, M&S and Waitrose closures on Boxing Day, while others ran reduced hours. Format and region influenced exceptions. Always verify with local store pages or apps, as individual trading patterns can differ. This distinction helps explain why more shopping moved into 27 December this year.

How do shorter Boxing Day hours affect margins?

Shorter hours can lower labour and utilities, but they also risk missed sales and later markdowns on fresh and seasonal lines. If 27 December captures demand at full price, gross margin holds. If traffic is soft, waste rises and margin compresses as promotions deepen to clear stock.

What KPIs should investors track on 27 December?

Focus on hourly footfall, conversion, average basket value, items per basket and gross margin mix. Check availability on fresh and drinks by midday, queue times, substitutions and click-and-collect slot fill. These indicators show whether displaced Boxing Day demand converts into profitable sales without heavy discounting.

Where can I confirm local supermarket opening times?

Use each retailer’s store finder for tesco boxing day hours, asda boxing day opening times and sainsbury's opening times. Also review national round-ups from reputable outlets for context. Local variations apply, so checking your nearest store page or app gives the most accurate hours.
