What Temperature Should Hot Food Be Held At?

In England, Wales, and Northern Ireland, the Food Safety and Hygiene (England) Regulations 2013 (and equivalent regulations in Wales and NI) require that hot food displayed for sale or held for service must be kept at 63°C or above. This is one of the most commonly checked items during an EHO inspection, particularly for businesses that operate buffets, carveries, bain-maries, or hot food counters. Scotland has the same 63°C requirement under the Food Hygiene (Scotland) Regulations 2006. The 63°C threshold exists because the temperature range between 8°C and 63°C — commonly known as the danger zone — is where pathogenic bacteria multiply most rapidly. At 63°C and above, bacterial growth is effectively prevented, making it safe to hold food for extended periods during service. However, food quality will deteriorate over time even at safe temperatures, so most guidance recommends not holding hot food for more than two hours where possible. There is a practical exception in the regulations: food that has been held at 63°C or above and is then being served or is on display for a single service period can be held below 63°C for a maximum of two hours, after which it must be discarded or reheated to at least 63°C. This is sometimes called the "two-hour rule" and is useful for buffet service, but it can only be used once — food cannot be cooled and reheated repeatedly. You must be able to demonstrate to an EHO that you are managing this process, so clear labelling with times is essential.
