Before you arrange a TM44 inspection
Can a TM44 inspection help reduce energy costs?
The report can identify opportunities to improve system efficiency, controls and operation. Any benefit depends on which recommendations are suitable and implemented, and how the building is used. An inspection alone does not establish a measured saving or guarantee a percentage reduction.
Review efficiency recommendationsCan I discuss inspections for several buildings?
Yes. Start with a site list, existing reports, known cooling equipment, deadlines and local access contacts. The office can discuss a coordinated programme, with each site's scope, assessor availability and fee agreed separately.
Plan a multi-site inspection programmeWhat should I expect in the inspection report?
The report should identify the premises, inspection date and accredited assessor, describe the systems assessed and record findings and recommendations. Confirm report and lodgement responsibilities in the quotation, then compare the delivered document with the agreed scope.
Understand the report and its referenceWhat should I do if an authority asks for inspection evidence?
Keep the actual notice and deadline, request the building's existing records and establish who controls the cooling systems. Follow the applicable jurisdiction's requirements. A website checker cannot decide enforcement liability or replace responding to the authority.
Review jurisdiction-specific enforcement guidanceCan I keep and share the report digitally?
Agree the report format and delivery method before commissioning the inspection. Retain the complete report and its applicable register reference, and pass the evidence to the person taking over responsibility for the system. A screenshot of a search result is not a substitute for the report.
Check report delivery and lodgementHow soon can an inspection be arranged?
Share your actual deadline, site access restrictions and the information available about the plant. Attendance, report preparation and lodgement dates need separate confirmation with the office. Requesting a quotation does not reserve a visit or guarantee a 24- or 48-hour service.
