Short answer: Commissioning records should identify the appliance and installer, exact model/serial, fuel and utilities, measured installation conditions, safety and functional tests, settings, defects, corrective work, user training, manuals, warranty and service requirements. Gas, electrical, water, refrigeration and ventilation records should be supplied by the relevant competent people.
A delivery note proves arrival, not correct installation. Commissioning establishes a baseline that supports warranty, planned maintenance and future fault diagnosis. The records should be stored against the asset number and accessible to operators and engineers—not left in a contractor’s email inbox.
Important: Only qualified people should issue statutory, gas, electrical or refrigeration records within their competence. Do not accept pre-signed blank forms or test values copied from another appliance.
Asset and installation identity
Record manufacturer, model, serial, asset tag, location, installer, date and the exact manual revision. Photograph the rating plate and final installation. List accessories, stands, treatment equipment and network/control connections so later service teams know the complete supplied configuration.
- Model, serial and asset number.
- Site and kitchen location.
- Installer and competent persons.
- Accessories/options and software.
- Photographs and as-installed drawing.
Measured services and functional tests
Record applicable water pressure/flow and treatment, drain operation, electrical supply and protection, gas safety/commissioning, refrigeration data, ventilation/interlock and appliance functional tests. Values should include units and test conditions. A tick without evidence is weak for a critical installation.
- Utility readings under relevant condition.
- Safety-device tests.
- Heat, fill, drain or cooling cycle.
- Alarm/interlock operation.
- Defects and retest results.
Operational handover
Provide user and installation manuals, cleaning and maintenance schedules, approved chemicals, consumables, warranty registration, service contacts and training. State actions operators may perform and those reserved for engineers. Record outstanding defects with owner and deadline.
- Operator training and attendance.
- Daily/weekly cleaning tasks.
- Planned service interval.
- Warranty conditions.
- Outstanding actions and responsibility.
What the observation may be telling you
| Observation | What it may mean | Correct next step |
|---|---|---|
| Delivery note | Confirms supply/receipt | Not commissioning evidence |
| Gas safety/commissioning record | Documents relevant gas work and checks | Must match appliance and competent engineer |
| Electrical test/certificate | Documents supply/installation work as applicable | Retain with distribution information |
| Functional commissioning sheet | Records appliance operation and settings | Use model-specific method |
| Training/O&M pack | Supports safe operation and maintenance | Make accessible at site |
A safe fault-reporting and verification workflow
Repeated resets and speculative part changes can hide an installation or utility problem. The safest and fastest route is to preserve the fault evidence, compare the installed conditions with the manufacturer’s requirements and let a competent engineer test the relevant system.
- Make the situation safe. Stop using equipment when there is a gas smell, burning, smoke, exposed live parts, flooding, persistent overheating or another immediate hazard. Follow the site emergency and isolation procedure; do not defeat a safety device to keep service running.
- Capture exact evidence. Record model, serial, displayed code, plain-language symptom, time, operating stage, load and recent work. Take photographs without opening guarded or live compartments. Preserve the sequence instead of repeatedly clearing the display.
- Check the installation baseline. Give the engineer the commissioning readings and service information for power, gas, water, drainage, ventilation, treatment and controls as applicable. A utility fault can appear as an appliance fault, and several units failing together is an important clue.
- Test, correct and prove. The competent person should diagnose using the manufacturer’s method, record measurements, correct the cause and run a representative cycle. Update the asset history so a recurrence can be compared with the same evidence.
Keep a useful record: For every attendance, retain the fault code and timestamp, measurements with units, test conditions, parts used, settings changed, cause identified and final functional test. “Reset and working” is not a sufficient record for a recurring failure.
Project or service checks
- Use one asset register for every appliance.
- Require measured values with units.
- Check serial numbers across all records.
- Close defects with dated evidence.
- Store manuals and warranty documents digitally.
- Link planned maintenance to the asset.
- Give operators access to the relevant safe-use information.
Turn the agreed checks into named deliverables. Each item should have an owner, due date and acceptance method. Where a measurement is required, record the value, unit, instrument or source, operating condition and result. This makes the information usable at handover and during a later investigation.
Common mistakes to avoid
- Accepting “tested OK” without method or readings.
- Losing gas/electrical records after fit-out.
- Commissioning before ventilation or water treatment is ready.
- Failing to record software/settings.
- Paying final account while critical defects remain unassigned.
Avoid closing the issue on appearance alone. A new filter, reset controller or revised drawing may change the symptom without resolving the underlying duty, utility, access or maintenance problem. Confirm the completed work under a representative operating condition and keep the evidence with the asset or ventilation record.
Frequently asked questions
Is commissioning the same as installation?
No. Installation places and connects the equipment; commissioning verifies the installed appliance and related systems operate as intended and records the result.
Who owns the documents?
The client/operator should receive and retain them, while contractors keep records required by their duties and contracts.
What if the manufacturer starts the equipment later?
Coordinate staged records so utility installation and final manufacturer commissioning form one complete handover trail.
