Keeping food at safe temperatures is one of the fastest ways to win over your EHO and protect customers. This guide gathers the UK legal and best-practice ranges most kitchens look for: fridge, freezer, delivery, cooking & reheating, hot holding, cooling, defrosting.
Quick reference: Keep chilled food at ≤8°C, frozen food at ≤-18°C, hot food at ≥63°C, cook/reheat to a safe core temperature (e.g., 75°C for 30 seconds or equivalent), and log everything consistently.
Fridges (UK food safety law)
- Target: 1-8°C (ideal 5°C)
- Record: at least twice daily per fridge
- If out of range: retake in 1 hour; if still high, remove from service and record corrective action
- Segregation: store raw and ready-to-eat separately to prevent cross-contamination
Freezers
- Target: ≤ -18°C
- Record: at least twice daily per freezer
- If warmer than -18°C: retake in 1 hour. If still high, remove from service and record corrective action
- Segregation: store raw and ready-to-eat separately to prevent cross-contamination
Food deliveries: acceptance temperatures
Record temperatures on arrival and document accept/reject decisions.
- Chilled items: 1-8°C
- Quick-frozen items: ≤ -18°C (acceptable to -15°C if unavoidable and re-frozen immediately)
- Normally frozen items: ≤ -15°C (acceptable to -12°C)
- If out of range: reject or isolate and log corrective action and reason for acceptance
Cooking temperatures
Probe the centre/thickest part of the food.
- Standard target: 75°C for 30 seconds
- Accepted time/temperature equivalents:
- 60°C for 45 minutes
- 65°C for 10 minutes
- 70°C for 2 minutes
- 80°C for 6 seconds
Batch policy: record the first batch and when you change product, size, load or equipment; spot-check during service.
Reheating temperatures
- Target: 75°C for 30 seconds (or the same equivalents above)
- Good practice: reheat rapidly, don't hot-hold from cold. Reach safe core temp before service
Hot holding
- Target: ≥ 63°C
- Monitoring: check at sensible intervals (e.g. every 2 hours) and log
- Time in lieu of temperature: food that drops below 63°C may be kept out of temperature control for up to 2 hours once only, then use, cool, or discard
Cooling
Cool cooked foods promptly to reduce bacterial growth:
- Goal: Cool from cooking to ≤ 8°C within 2 hours
- How to speed it up: shallow trays, smaller portions, blast chiller, ice bath; avoid tight lids while hot
- Logging: record start time/method and when food reaches ≤ 8°C
Cold holding / display
- Chilled display: keep ready-to-eat foods ≤ 8°C
- Buffets & events: where refrigeration isn't practical, use time control - max 4 hours unrefrigerated, then discard; clearly mark the start time
Defrosting
- Defrost in the fridge (≤ 8°C) or under cold running water
- Keep foods covered and separate from ready-to-eat items while thawing
- Drain and cook promptly; never re-freeze raw foods once fully thawed (unless cooked first)
Probe care & calibration
- Between uses: sanitise probes with food-safe wipes
- Regular calibration: check in boiling water (~100°C) and ice water (~0°C) and record results
- If off: recalibrate or replace and note the corrective action
Quality vs food safety
Some checks are essential good practice, but not food hygiene items:
- Cellar temperatures: 10-13°C (beer/wine quality)
- Legionella checks: Hot ≥ 50°C, Cold ≤ 20°C (health & safety)
Opening & closing checks
- Visual cleanliness & equipment check
- Pest evidence checks
- Fridge/freezer log reminders
- Probes present, charged, sanitised

FAQs
What is the legal fridge temperature in the UK?
Keep chilled foods at 8°C or below. Most kitchens target 5°C to stay comfortably within range. See the FSA Safer Food Better Business guide for full requirements.
What temperature should freezers be in the UK?
-18°C or colder. Record at least twice daily per unit. This is a legal requirement under the Food Safety Act 1990.
What temperature should food be cooked to in the UK?
A common safe target is 75°C for 30 seconds at the core. You can also use approved time/temperature equivalents like 70°C for 2 minutes. See the FSA HACCP guidance for full details.
What temperature is hot holding in the UK?
63°C or above. If food drops below this, you can use time control for up to 2 hours once only.
How quickly must food be cooled?
From cooking to ≤ 8°C within 90 minutes-2 hours. Use shallow pans, blast chillers or ice baths to speed it up.
Can I defrost food at room temperature?
No. Defrost in the fridge or under cold running water. Keep separate from ready-to-eat foods.
Do I need to calibrate my probe?
Yes. Check ~100°C (boiling) and ~0°C (ice water) regularly and record the results.
What happens if my fridge goes out of temperature during service?
Record the issue, retake the temperature after 1 hour. If still high, remove the unit from service and document the corrective action. Keep a compliance log for your EHO inspection.
