Quick summary

What temperatures must I control in a restaurant kitchen?

In a busy UK restaurant kitchen, the core temperatures you're expected to control are clear. Your walk-in and under-counter fridges must stay at or below 5 °C, while freezers need to sit at −18 °C or colder. When you're holding hot food for service, keep it above 63 °C. Cooking is about hitting the right core temperature: 75 °C instantly, or an equivalent 70 °C for 2 minutes. And don't forget incoming deliveries — chilled goods should arrive at 5 °C or below and frozen at −18 °C or below before you even accept them.

Checking these temperatures isn't a once-a-week job; you should record them at least once a day, ideally at opening and closing, and on every single delivery. During busy service, when fridge doors are opened often, a brief tolerance of around 3 °C is realistic, but you must log it and get the temperature back down quickly. Probe placement matters: in a cold room, measure at the point furthest from the evaporator; when cooking, push the probe into the core of the food, not touching bone or the pan. For rapid cooling, your blast chiller needs to bring food from 60 °C to 10 °C in under 2 hours to stay safe.

Let's be honest: no app, checklist or template can make you 'inspection-ready' or guarantee you a top hygiene rating. Timlup simply helps you document, in an orderly way, whatever you choose to record. Every day you get an auto-generated checklist on the kitchen tablet; your team signs off with a PIN, and the exact time is captured automatically. If a check gets missed, a gentle reminder nudges the right person, and your entire history is exportable whenever you need it. The structure mirrors the kind of records you'd keep with the FSA's Safer Food, Better Business pack, so it feels familiar without pretending to be a magic wand.

A kitchen's temperature control points, step by step

Total estimated time 12-16 min a day across goods-in, opening, service and closing. Ranges per UK food safety guidance and the FSA's Safer Food, Better Business. Temperature-logging tasks are marked.

Goods-in (delivery)

3-4 min — on every delivery, before accepting the order

1 Probe the temperature of chilled goods on arrival (5 °C or below); reject or log an incident if the cold chain is broken 2 min
2 Check the temperature of frozen goods on arrival (−18 °C or below); note supplier, time and temperature 1 min
3 Put each item straight into its fridge or freezer so the cold chain isn't broken 1 min

Opening

5 min — first log of the day, before service

1 Check and log the main cold room / fridge temperature (5 °C or below); probe at the point furthest from the evaporator 1 min
2 Check and log the under-counter and pass fridges (5 °C or below) 1 min
3 Check and log the freezer temperature (−18 °C or below) 1 min
4 Verify probes/thermometers work and are calibrated; log any issues (frost, noise, poorly sealed doors) 1 min
5 Visually confirm no perishable was left out of cold equipment overnight 1 min

Service (cooking, hot-holding and chilling)

3-4 min — during service, at the critical points

1 Probe the core of cooked dishes to confirm 75 °C (or 70 °C for 2 minutes); take extra care with poultry, mince and stuffed items 1 min
2 Log the hot-holding / bain-marie temperature (above 63 °C); probe the food itself, not just the water 1 min
3 Log blast-chiller cooling: bring the core from 60 °C to 10 °C in under 2 hours; note start time, end time and temperatures 1 min
4 Re-check the cold room or pass fridge after repeated door openings (5 °C or below; brief ~3 °C tolerance if it recovers fast) 1 min

Closing

4 min — second log of the day, confirms the cold held all shift

1 Check and log the closing cold room / fridge temperature (5 °C or below) 1 min
2 Check and log the closing freezer temperature (−18 °C or below) 1 min
3 Date-label opened or prepared items, store in the fridge at 5 °C or below and log the temperature 1 min
4 If any unit went out of range during the day, log the incident and the corrective action taken (move product, fitness check, call technician) 1 min

Why Timlup

Three ways Timlup helps with temperature logging

Without ever pretending to be a compliance tool.

Recurring checklists, not random alerts

Your daily fridge and freezer checks appear automatically on the kitchen tablet, at the times and frequency you decide. No more WhatsApp reminders, no more sticky notes peeling off the walk-in door.

PIN sign-off with real traceability

Every single check is signed with the personal PIN of the team member who actually did it, stamped with the exact date and time. If you need to know what happened on a particular shift, you can find it in seconds.

Tidy history, no paper or spreadsheets

All your records are stored automatically and neatly in one place, ready to export a whole year's worth if you ever need to. No more soggy paper logs that nobody can find when you actually want them.

FAQ

Your temperature logging questions, answered

Straightforward answers for restaurant owners and head chefs.

How often should I record temperatures in a restaurant kitchen?

You must record temperatures at least once daily, but best practice is to do it at opening and closing to catch any overnight fluctuations. Every single chilled or frozen delivery must be checked and logged before you accept it, rejecting anything above the legal limit. Increase checks to twice daily for high-risk units, on exceptionally busy days when doors are open frequently, or for older equipment that is prone to drifting. The FSA's Safer Food, Better Business pack makes it clear that a single morning check is not enough to prove continuous control throughout a full service period. Remember that a record is only useful if it is timely, accurate and signed, so never be tempted to fill in logs in advance. In a busy UK kitchen, syncing these checks with key shift changes, such as after the lunch rush and before dinner prep, usually provides the most honest and defensible data.

What temperature should my fridges and walk-in cold rooms be?

Your fridges and walk-in cold rooms should operate at or below 5 °C in the UK, the cold-holding temperature the Food Standards Agency expects for high-risk ready-to-eat foods. While some display fridges may briefly cycle higher, commercial restaurant chill storage should be calibrated firmly to 5 °C or colder to give a margin of safety, especially in walk-in units where the door seals are repeatedly broken. The air temperature reading is a guide, but your safety depends on the temperature of the food on the middle shelves, not just the digital display on the door. The SFBB diary recommends taking your reading from between packs in the warmest part of the unit, usually at the front near the door, to confirm your equipment is coping. Packing units too tightly or putting hot food inside to cool down will sabotage this target, so good air circulation matters as much as the compressor setting.

What temperature should my freezer be?

Your freezer must run at or below -18 °C, the UK standard for frozen storage that keeps food in a safe solid state. A brief minor rise during an automatic defrost cycle is completely normal, but the unit must recover back down to at least -18 °C quickly once the cycle finishes, and a visual check on the food itself is vital so you can spot soft packaging or ice-crystal deformation. If your log shows the air rose to -15 °C for a short defrost period, the food likely stayed safe; but if it has reached -5 °C and the edges are softening, you have a problem that must be recorded and acted upon. Simply looking at the unit's own built-in display is not enough, so use a stand-alone probe or an infrared surface thermometer on the product to verify the display is not lying. For walk-in freezers, a morning check of the door seals and ice build-up around the evaporator can stop a temperature drift before it becomes a costly stock loss.

What temperature should hot-holding and the bain-marie be?

In a UK kitchen, hot food must be held at a core temperature above 63 °C, a control point that applies to the thickest part of the food itself, not just the bubbling water in the base of the unit. The bain-marie can be misleading, because the water might be 80 °C while a dense mash or chilli in a gastronorm pan on top is sitting at a dangerous 50 °C, so you must stir the food and probe it directly. Under FSA guidance backed by the SFBB pack, if that core temperature drops below 63 °C during service, you may reheat it immediately to above 75 °C one time only; if it drops again or you cannot reheat it effectively, the rule is honest and simple: discard it. Never use the hot-holding cabinet to slowly reheat food from cold either, because it cannot achieve a safe kill of bacteria; food must already be piping hot when placed into the bain-marie. Recording the food's core temperature at the start of the holding period, and again mid-way through a long service, protects your customers and supports your due-diligence defence.

What core temperature must food reach when cooking?

The safe time-temperature combination in a UK commercial kitchen is to reach a core of 75 °C, or alternatively to hold the core at 70 °C for a solid two minutes, which kills the majority of harmful vegetative bacteria such as campylobacter in poultry and E. coli in minced meats. Probing technique is non-negotiable: insert a sanitised probe into the geometric centre or thickest part, avoiding bone, gristle and the pan bottom, because these give a falsely high reading that might leave the core dangerously raw. For poultry, rolled joints, reformed minced-meat dishes and liver, hitting this target is a mandatory control point because surface bacteria will have been mixed deep into the product. If you are serving a burger less than well done to a vulnerable customer, the FSA warns against it unless you have a verified, documented HACCP procedure that goes beyond standard Safer Food guidance. Always clean and sanitise your probe between each test to avoid cross-contamination, and if it reads 72 °C, wait a moment to see if residual heat climbs to the safe 75 °C before logging.

How do I control rapid cooling with a blast chiller?

Use the blast chiller to bring the food's core temperature down from 60 °C to 10 °C within two hours, crossing the danger zone as quickly as possible, then on to 5 °C or below for storage. This matches the FSA's cooling benchmarks and helps stop bacteria multiplying. Always log the start and end times along with the corresponding core temperatures. Timlup lets you record these steps in an orderly way, so you have a clear log of what you chose to record.

What temperature should I check on delivery (goods-in)?

Probe a sample of chilled items between the packs; their recommended maximum is 5 °C, though some suppliers aim lower, so check your specification. Frozen deliveries should arrive at -18 °C or below. If anything is out of range, reject it or quarantine and log the incident, noting the supplier, time and temperature. This helps you show you received ingredients that started safe, without pretending to be flawless. Timlup's goods-in checklist lets you record that in an orderly way, exactly as you choose.

Where should I place the probe in a cold room and when cooking?

In a cold room, measure at the spot furthest from the evaporator, often a top shelf near the door, because that is where warm air lingers. When cooking, push the probe into the centre or thickest part of the food, well away from bone and the cooking pan, to read the slowest-heating point. Always use a clean, recently calibrated probe to get reliable numbers. Recording those positions alongside the temperature gives you a fuller picture, and Timlup makes it simple to log exactly where you probed so your checks stay transparent and useful.

How long should I keep temperature records?

The FSA expects you to keep records for at least 12 months, and the Safer Food, Better Business system suggests you hold on to them longer if you can. Digital logs do not fade or get coffee-stained, and they are instantly searchable when an environmental health officer asks to see them. Timlup stores your history securely and lets you export anything you need. A solid digital trail means you are documenting in an orderly way, not chasing paper.

What should I do if a fridge or unit goes out of range?

First, check for simple explanations like a door not fully closed or a recent warm delivery; if it is a brief spike, note it. If the unit does not recover quickly, move high-risk food to a working fridge and assess whether anything has sat in the danger zone too long; when in doubt, bin it. Log the time and temperature you spotted the fault, the action you took, and what happened next. Documenting your corrective action matters just as much as the temperature reading itself. Timlup's checklist gives you a clear, orderly way to record that whole sequence, exactly as you choose.
