Commercial Heating Commissioning

Commercial heating commissioning is the process of testing, setting up and verifying a heating system after installation, upgrades or repairs. It confirms the plant and controls operate safely, efficiently and as intended, and provides clear records for handover and compliance.

More information

What commercial heating commissioning covers

Commissioning turns an installed or repaired system into one that performs reliably day to day. Depending on the site and equipment, commissioning can include:

  • Pre-commission checks on plant, pipework, electrics and isolation points
  • Filling, venting and pressure checks (where applicable)
  • Basic water quality checks and confirmation of dosing and filtration approach
  • Verification of pumps, valves, pressurisation equipment and expansion provision
  • Control set-up: time schedules, setpoints, zoning and interlocks
  • Safety checks on key protections and safe shut-down operation
  • Functional testing to confirm heat delivery to all served areas
  • System balancing and adjustment to improve comfort and reduce wasted energy
  • Recording of settings, test results and any defects to resolve
  • Practical handover notes so your facilities or site team can run the system confidently

When commissioning is most useful

This service is a fit when you need confidence that a commercial system is operating correctly and can be signed off.

  • After a new boiler or plant installation
  • After major repairs, upgrades or control changes
  • Following tenant fit-outs or alterations to layout and zoning
  • If you are seeing cold spots, overheating, noise, air issues or recurring breakdowns
  • Before taking over a managed property or starting a new maintenance contract

How the commissioning is delivered

Work typically starts with a review of the system design intent, controls and access requirements. On site, the system is tested in stages, then adjusted and re-tested until it meets safe operating requirements and performs as expected. You will be kept informed of any constraints found, plus any remedial work needed before full sign-off.

After commissioning

You receive a clear summary of what was tested, what was set, and what to monitor. Where issues are identified, you get a prioritised list of actions to resolve them, plus options for ongoing planned maintenance and periodic re-commissioning to keep performance stable.

Frequently Asked Questions

What is commercial heating commissioning?
Commissioning is the process of testing and setting up a heating system so it operates safely and as designed. It includes functional checks, control set-up and performance verification. It also provides a documented record for handover and compliance.
Can you commission a system installed or repaired by another contractor?
Yes, commissioning can be carried out on third-party installations and repair works. If faults or missing elements are found, they will be recorded clearly. Remedial work may be required before the system can be fully signed off.
What documentation will we receive after commissioning?
You will receive a clear record of checks completed, key settings and test results. Where relevant, this can include commissioning sheets, control setpoints and a snag list. The aim is to leave you with practical information for operation and compliance files.
How disruptive is commissioning in an occupied building?
Some testing requires plant start stop and may affect heat availability briefly. Access to plant rooms, controls and key areas is normally needed. Work can be planned around trading hours or occupants where practical.
How often should a commercial heating system be re-commissioned?
Re-commissioning is recommended after significant changes, upgrades or repeated performance issues. Many sites also benefit from periodic checks as part of planned maintenance, particularly ahead of winter. The right interval depends on usage, controls complexity and past reliability.
