Temperature control is the single most-checked thing in a UK kitchen and the single most-backfilled. Fridges at open and close, cooking probes through service, hot holding on the pass, cool-down at the end of the night. Each reading is quick; together they are the record an Environmental Health Officer reads first. So the real question about a kitchen temperature log app is not features. It is whether the reading gets logged when the probe comes out, or written up in one neat block after close from memory.

Kitchen temperature log app for the UK.
A practical guide to recording fridge, freezer, cooking and hot-holding temperatures in a busy kitchen, from the paper diary on the wall to a WhatsApp workflow that logs every reading with a timestamp and flags anything out of limit.
14-day free trial. No card required.
The point
A log app does not keep the fridge cold.
The maintenance and the practice do. What a log does is prove the temperature was checked and give you an early flag when a unit drifts. A good one means nobody writes a week of fridge readings from memory, all in the same neat pen, on a Friday afternoon.
The readings that matter
What a UK kitchen has to record.
Chilled storage
Fridges at or below 8C
Chilled food should be held at or below 8C. Many operators run fridges colder as a working target and log each unit at open and close.
Cooking and hot holdingCore 75C, hot hold 63C
Cooking to a safe core, commonly 75C or an equivalent time and temperature, and hot holding at or above 63C. Both are probe readings, logged as taken.
Cooling and freezersSafe cool-down and frozen
Cooked food cooled quickly and safely, and freezers held frozen. The cool-down record is one an EHO often looks for and staff often forget.
The friction
The wall diary is the one that gets backfilled.
A paper log on the wall is quick until it is busy, and then it waits. The readings that get written at close, from memory, are the ones that fail you when a fridge actually drifted at 11am. The record you take at the point of the check is the only one worth keeping.
Log temperatures on WhatsApp
No app install. No training.
Staff use the phone they already have. The check arrives as a message; they reply with the reading, a voice note or a photo of the probe. Out-of-limit values flag instantly and head office sees every unit across every site.
The short version
- Chilled food is generally held at or below 8C; hot food at or above 63C; cooking aims for a core of 75C or an equivalent time and temperature.
- Fridge, freezer, cooking, hot-holding and cool-down readings are the backbone of the daily food safety diary.
- The reading logged at the point of the check is worth keeping; the one written from memory at close is not.
- An out-of-limit reading with a recorded corrective action protects you. A blank line does not.
- An app does not keep the fridge cold. It proves the check happened and flags a unit that is drifting.
- Per-report pricing beats per-seat for a group, because adding staff and sites is free.
The numbers
UK temperature limits, plainly
UK food safety law sets the key limits. Chilled food that needs temperature control is generally held at or below 8C. Hot food held for service is kept at or above 63C. Cooking aims for a safe core temperature, commonly 75C for 30 seconds or an equivalent time and temperature combination such as 70C for two minutes. Cooked food that is not served hot should be cooled as quickly as possible and refrigerated.
These are the limits your daily log checks against. An app does not keep the fridge cold; maintenance and practice do. What a log does is prove the check happened and give an early flag when a reading drifts. Always check current Food Standards Agency guidance for the exact figures and any local requirements; this is not legal advice.
The daily readings
What to log and when
Fridges and freezers. Log each unit at open and close, or more often if a unit is unreliable. A drifting fridge caught at the morning check is a repair; caught at close is a bin.
Cooking. Probe the core of cooked dishes to confirm a safe temperature, especially for high-risk items. Log the reading against the dish.
Hot holding. Check food on hot hold stays at or above 63C through service.
Cool-down. Record that cooked food was cooled quickly and moved to chilled storage. This is the record staff most often forget, and one an EHO often asks for.
Out of limit
The corrective action is the real record
A reading within limits is routine. A reading out of limit is where the record earns its keep. A fridge at 11C with a note that stock was moved, the temperature rechecked and the unit called in for repair is a record that shows a working system. The same 11C with no note, or no reading at all, is the one that costs you.
Quickler prompts for each reading, flags an out-of-limit value the moment it is entered, and captures the corrective action in the same WhatsApp conversation. Head office sees the flag straight away, not three weeks later when someone reads the diary. The out-of-limit event and its fix become part of your due-diligence record.
Head office
Every unit, every site, one view
Across a group, temperature logs are scattered across a dozen kitchen walls. You cannot see from head office that every fridge was checked this morning, and a failing unit at one site is invisible until it spoils stock or an inspector finds the gap.
Quickler puts every unit's readings on one dashboard: which site logged what, when, and any out-of-limit flag with its corrective action. A missed morning check reads as a gap the same day. A fridge that keeps drifting shows a pattern before it fails. The logs fold into the wider HACCP daily diary rather than living on a separate sheet.
Questions, answered
What temperature should a commercial fridge be in the UK?
UK food safety law requires chilled food that needs temperature control to be held at or below 8C. Many operators set fridges to run colder, often around 1C to 4C, as a working target so a small drift does not breach the legal limit. Check current FSA guidance and your own HACCP plan for the figures that apply to your business; this is not legal advice.
What core temperature should food be cooked to?
Cooking aims for a safe core temperature, commonly cited as 75C for 30 seconds or an equivalent time and temperature combination such as 70C for two minutes or 80C for six seconds. Hot food held for service should stay at or above 63C. Always follow current FSA guidance and your own safe methods.
Can I log kitchen temperatures over WhatsApp?
Yes. Quickler's temperature checks run over the WhatsApp Business API. Each check arrives as a message in your team's existing WhatsApp chat; staff reply with the reading, a voice note or a photo of the probe, and the log generates automatically with a timestamp. Out-of-limit values flag immediately. No separate app or login is required, and Quickler manages the WhatsApp Business API account on the firm's behalf.
Does a temperature log app replace a probe thermometer?
No. Quickler records the reading the member of staff takes with a calibrated probe or fridge thermometer and stores it with a timestamp and, where useful, a photo. It is not itself a measuring instrument and does not keep the fridge cold. The calibrated probe and good practice do that; the log proves the check happened.
