Testing and Commissioning
This approach suits new installations, altered services and projects with interacting systems. It is essential to plan the checks early where equipment, controls and building operation need to be demonstrated together.
Discuss your requirementsProjects are judged by their evidence.
What the work includes
- Define systems, boundaries and acceptance requirements.
- Identify prerequisites and specialist test responsibilities.
- Sequence component and integrated-system checks.
- Record measurements, settings and findings.
- Resolve failures and assemble the commissioning package.
Important decisions
Distinguish installation inspection, functional testing and performance demonstration. A component passing its own test does not establish that the connected system operates correctly. Agree the conditions, witnesses and evidence needed for acceptance, including any tests that require seasonal conditions or normal occupancy.
Assessment and the project brief
Provide design requirements, schematics, equipment schedules and control descriptions. Identify test points, calibrated-instrument requirements and who can authorise isolations or operational simulations.
How the project proceeds
- Prepare the test and commissioning requirements.
- Confirm installation readiness and safe test conditions.
- Perform the agreed component and system checks.
- Correct findings and repeat affected tests.
- Record final results, settings and operating information.
Working in occupied properties
Plan any alarms, plant shutdowns or changes in operating conditions with the site team. Testing that affects occupants or other systems needs a defined window and a clear restoration sequence.
Budget and programme factors
The number of systems, test complexity, witnessing, access and readiness affect time and cost. Failed prerequisites can create repeat attendance. Include the time needed to correct findings and retest, and identify deferred seasonal checks separately.
Completion and handover
Retain final test results, settings, instrument information where relevant and the status of every outstanding test. Connect the records to asset identifiers so future faults can be compared with the established operating condition.
Projects across sectors
Data centres and critical environments need interfaces and failure scenarios carefully defined. Offices need controls and room conditions demonstrated. Healthcare and care need operational interruptions planned around users. Explore the full sector range to connect the project with the premises and its users.
Frequently asked questions
Is switching equipment on the same as commissioning?
No. Commissioning checks and sets up the installation against defined requirements, with measurements or functional evidence appropriate to the system.
Can testing be left until the last day?
The requirements should be planned early. Access, specialist attendance, system readiness and time for corrections need to be included in the programme.
What happens when a test fails?
Record the finding, identify the corrective work and repeat the affected test after correction. Acceptance should use the final result rather than the original failed record.
Why might a test be deferred?
Some performance checks need particular weather, occupancy or connected-system conditions. Record the reason, required conditions and responsibility for completing the deferred test.
