Fridge & Freezer Temperature Log Requirements (UK & EU)

Walk into any kitchen inspection and the first document the environmental health officer asks for is almost always the same: the temperature log. Fridge and freezer checks are the backbone of food safety compliance across the UK and EU, and the rules on what to record, how often and for how long are more specific than many food business owners realise. This guide sets out exactly what is required — the legal limits, the best-practice targets and the paperwork that keeps you covered.

1. What the law actually requires

Two layers of law apply to every restaurant, café, takeaway and food truck operating in the UK or EU.

Regulation (EC) 852/2004 on the hygiene of foodstuffs — retained in UK law after Brexit — requires every food business to put in place food safety procedures based on HACCP principles, to maintain the cold chain for any food that cannot safely be kept at room temperature, and to keep documents and records commensurate with the nature and size of the business. In plain English: if refrigeration is what keeps your food safe, you must monitor it and be able to prove you did. HACCP temperature monitoring is the textbook example of a critical control point — our plain-English HACCP guide explains how it fits into the wider system.

National regulations set the actual numbers. In England, Wales and Northern Ireland, the Food Hygiene Regulations 2006 make it an offence to hold chilled food above 8°C. Scotland's regulations do not name a figure, but require chilled food to be kept cold enough to remain safe — in practice, Scottish businesses work to the same 8°C standard.

Note what the law does not say: nowhere is a paper fridge temperature log sheet, filled in twice a day, spelled out as a legal requirement. What is required is that you monitor your critical limits and can demonstrate control. A written or digital temperature log is how virtually every inspector expects you to demonstrate it — and without one, you have no evidence for a due diligence defence if something goes wrong.

2. The temperatures that matter

Pin these numbers up in the kitchen. They cover the whole journey food takes through your business, not just cold storage.

The gap between the 8°C legal maximum and the 5°C target is deliberate. Fridges drift — door openings during a busy service, defrost cycles, warm stock loaded straight from a delivery. Running at 5°C or below gives you a working margin, so a brief rise never tips food over the legal limit.

3. How often to check fridge temperature

The law does not fix a frequency, but the standard across the industry — and what environmental health officers expect to see — is twice daily: once at opening and once at closing.

• Opening check: confirms every unit held temperature overnight, before you commit the day's prep to it.
• Closing check: confirms units are sound before stock sits unattended for twelve hours or more.
• Delivery checks: probe or inspect every chilled and frozen delivery. Chilled goods should arrive at 8°C or below and frozen goods at or close to -18°C — this is your end of the cold chain, and accepting a warm delivery makes the problem yours.

One detail that catches people out: the display on the fridge door shows air temperature, which swings with every door opening. The legal limit applies to the food. If a display reading looks high, probe between packs — or keep a probe in a food simulant such as a sealed bottle of water — before deciding whether you have a real problem. Check your probes regularly in iced water (they should read between -1°C and 1°C).

4. What a compliant fridge temperature log sheet includes

Whether on paper or in an app, every entry in your food temperature records should capture:

• Date and time of the check
• Which unit was checked (Fridge 1, walk-in, chest freezer — label them)
• The actual reading, not a tick
• Initials of the person who checked
• Any corrective action taken, and its outcome

Your limits should come from your HACCP plan, not from habit — if you have never written them down, start with our free HACCP plan template. If you run on Safer Food, Better Business, the SFBB diary expects the same daily records; see our guide to a digital alternative to the SFBB diary if the paper pack is not keeping pace with your kitchen.

5. What to do when a reading is out of range

An out-of-range reading is not a crisis. An out-of-range reading with no recorded action is. A log showing years of perfect readings and not a single corrective action tends to raise an inspector's eyebrows — real fridges fail. When a fridge reads above 8°C:

• Check the obvious causes first: a door left ajar, warm stock just loaded, a defrost cycle running.
• Probe the food itself. If the food is still at 8°C or below, note the air-temperature blip and recheck within the hour.
• If the reading does not come down, move stock to another unit and call out an engineer.
• Assess any food that has gone above 8°C against the four-hour rule below, and bin anything you cannot vouch for.
• Record every step: the reading, the action, the recheck, the outcome.

6. How long to keep food temperature records

There is no single statutory retention period for temperature logs, but the widely followed recommendation in the UK is to keep them for two years. As an absolute minimum, keep records well beyond the shelf life of the food they relate to.

The reason is the Food Safety Act 1990. Your defence against a hygiene charge is due diligence — proving you took all reasonable precautions — and a complete, dated temperature log is precisely that proof. A missing month is a hole in your defence. Store your logs with the rest of your compliance paperwork — your HACCP plan, cleaning schedules and allergen matrix — so everything is to hand on inspection day.

7. Paper log sheets vs digital temperature logs

Paper works, but it fails in predictable ways: sheets go missing, checks get skipped on the busiest days, and a full week filled in with the same pen in the same handwriting is something experienced EHOs spot instantly. Paper also cannot remind anyone to do anything.

A digital temperature log timestamps every entry, prompts staff when a check is due, insists on a corrective action when a reading is out of range, and exports a clean, dated history the moment an inspector asks for it. HACCPapp for Android was built for exactly this: fridge and freezer checks, cooking, cooling and hot-holding temperatures, and the rest of your daily diary in one place.
