Temperature checks are the backbone of food safety in any restaurant, cafe, or food service business. In 2025, with stricter regulations and increased scrutiny from health inspectors, getting your temperature checks right isn’t just important—it’s essential for staying in business.

This comprehensive guide covers everything you need to know about temperature checks, from legal requirements to practical implementation, helping you protect your customers and your business.

What Are Temperature Checks and Why Are They Critical?

Temperature checks are systematic measurements of food and equipment temperatures to ensure food safety. They’re your first line of defence against foodborne illness and are legally required in the UK under food safety regulations.

The Three Types of Temperature Checks Every Restaurant Needs

  1. Equipment Temperature Checks

    • Fridges (must be between 1°C and 5°C)
    • Freezers (must be at or below -18°C)
    • Hot holding equipment (must maintain 63°C or above)
    • Display units and prep stations

  2. Food Temperature Checks

    • Incoming deliveries
    • During cooking (75°C core temperature for 30 seconds)
    • Before service
    • During hot holding
    • After cooling

  3. Environmental Temperature Checks

    • Prep areas
    • Storage rooms
    • Service areas

UK Legal Requirements for Temperature Checks

Under the Food Safety Act 1990 and Food Hygiene Regulations 2006, UK businesses must:

Mandatory Temperature Standards

  • Cold Storage: Maximum 8°C (recommended 1-5°C for fridges)
  • Frozen Storage: -18°C or below
  • Cooking: Minimum 75°C core temperature
  • Hot Holding: Minimum 63°C
  • Cooling: From 63°C to 8°C within 90 minutes
  • Reheating: Minimum 75°C throughout

Documentation Requirements

Environmental Health Officers (EHOs) expect to see:

  • Daily temperature logs for all fridges and freezers
  • Records retained for minimum 3 months
  • Clear corrective action documentation
  • Staff signatures and timestamps
  • Calibration records for thermometers

Daily Temperature Check Routine: A Step-by-Step Guide

6:00 AM - Opening Checks

  1. Check and record all fridge temperatures
  2. Check and record all freezer temperatures
  3. Verify cold room temperatures
  4. Test probe thermometer accuracy with ice water
  5. Document any overnight issues

Pre-Service Checks

  1. Check prep station temperatures

Best Practices for Accurate Temperature Checks

Choosing the Right Thermometer

Probe Thermometers

  • Best for: Checking food core temperatures
  • Accuracy: ±0.5°C
  • Must be cleaned between uses

Infrared Thermometers

  • Best for: Surface temperature checks
  • Accuracy: ±1°C
  • Cannot measure internal temperatures

Data Logging Thermometers

  • Best for: Continuous monitoring
  • Accuracy: ±0.5°C
  • Provides alerts and historical data

Calibration and Maintenance

  1. Daily Calibration Check

    • Ice water test (should read 0°C)
    • Boiling water test (should read 100°C at sea level)
    • Document calibration results

  2. Weekly Maintenance

    • Clean and sanitise all probes
    • Check battery levels
    • Verify digital displays are working

  3. Annual Professional Calibration

    • Required for compliance
    • Keep certificates for inspections

Common Temperature Check Mistakes and How to Avoid Them

Mistake 1: Inconsistent Timing

Problem: Checking temperatures at random times
Solution: Set specific times (e.g., 7 AM and 2 PM) and use reminders

Mistake 2: Not Checking Core Temperatures

Problem: Only checking surface temperatures
Solution: Always probe the thickest part of food items

Mistake 3: Poor Record Keeping

Problem: Incomplete or illegible logs
Solution: Use digital systems or clear templates with mandatory fields

Mistake 4: Ignoring Out-of-Range Readings

Problem: Not taking corrective action
Solution: Implement clear escalation procedures

Mistake 5: Cross-Contamination via Probes

Problem: Using dirty probes between foods
Solution: Clean and sanitise between different food types

Digital vs Paper Temperature Checks: Making the Right Choice

Paper-Based Systems

Pros:

  • Low initial cost
  • No technology required
  • Simple to understand

Cons:

  • Time-consuming (30-45 minutes daily)
  • Prone to errors and illegibility
  • Difficult to analyse trends
  • Storage and retrieval challenges
  • Easy to falsify

Digital Temperature Check Systems

Pros:

  • Automated reminders and alerts
  • Real-time compliance monitoring
  • Instant reporting for inspections
  • Trend analysis and predictive insights
  • Time-stamped, tamper-proof records
  • 75% reduction in admin time

Cons:

  • Initial setup cost
  • Staff training required
  • Internet dependency for cloud systems

ROI Calculation Example

Traditional Paper System:

  • Time spent: 45 minutes/day
  • Staff cost: £12/hour
  • Annual cost: £3,285 in labour alone

Digital System (like Forkto):

  • Time spent: 10 minutes/day
  • Annual labour cost: £730
  • Annual savings: £2,555 plus reduced compliance risk

Handling Temperature Check Failures

Immediate Response Protocol

  1. For Fridge Temperature Above 8°C:

    • Check door seals and close properly
    • Reduce stock levels if overloaded
    • Call engineer if temperature doesn’t drop within 1 hour
    • Move high-risk foods to alternative storage

  2. For Freezer Temperature Above -15°C:

    • Do not open door unnecessarily
    • Check for ice build-up
    • Call engineer immediately
    • Monitor and document food condition

  3. For Hot Food Below 63°C:

    • Reheat immediately to 75°C
    • Discard if out of temperature for over 2 hours
    • Investigate equipment failure
    • Document disposal

Documentation Requirements

Every temperature failure must include:

  • Date and time discovered
