The provider’s report, a contractor’s remedial work and a measured reduction in energy use are three separate outputs. This guide helps clients buy each one deliberately and avoid assuming that an inspection appointment automatically delivers all three.
What you need to know
- Check accreditation and experience relevant to the equipment.
- Provide records that explain how the installation is used.
- Ask for recommendations tied to observed conditions.
- Agree further engineering and measurement as separate work.
Check the assessor rather than only the brand
Ask who will undertake the accredited energy assessment and how their current accreditation can be checked. Discuss experience with the installed system type and the level of assessment required.
A provider’s maintenance capability or sales team does not establish the competence of the named energy assessor. Record the commissioning organisation, assessor and agreed deliverables so responsibilities remain clear.
Give the provider operational evidence
Include the asset schedule, service history, control descriptions and typical working hours. Explain recurring complaints or manual overrides rather than presenting an equipment list without the context in which it operates.
If records conflict, identify the discrepancy before the visit. A missing drawing is a reason to clarify scope, not permission to fill the report with unverified capacities or assumptions about tenant use.
Expect findings linked to the installation
Useful advice explains the observed issue, affected equipment and rationale for further action. A suggestion about condenser obstruction should be traceable to a location; a control recommendation should relate to the way the building is operated.
Ask for clarification where a recommendation is too broad to allocate. Do not require the assessor to turn a limited inspection observation into a design specification or a guaranteed return on investment.
Identify work outside the assessment
Detailed controls optimisation, intrusive testing, repair and plant replacement may need another appointment and a different scope of competence. Agree who owns the design, commissioning and operational approval before authorising those activities.
Keep inspection recommendations available to contractors without assuming the assessment provider has been appointed to carry out the work. If the same company offers both services, review each scope and commercial decision separately.
Evaluate proposed savings transparently
Ask what consumption data and operating assumptions support an estimated improvement. Separate kWh estimates from monetary calculations and record the tariff used; both the engineering outcome and financial value can differ from an initial estimate.
Reject generic percentages presented as a confirmed result for an unseen building. Where metering is limited, commission an appropriate monitoring plan or describe the uncertainty rather than inventing a precise saving.
Commission the next step clearly
Your inspection brief should state the evidence needed, equipment boundaries and known operational constraints. An additional efficiency investigation should have its own question, deliverables and approval route.
When requesting a quote, explain whether you need the statutory assessment, investigation of a particular recommendation, or both. This prevents a routine inspection fee being mistaken for an unlimited engineering service.
Prepare an inspection enquiryCheck the governing guidance
This article does not authenticate a government register entry or establish the status of an individual building. Confirm the applicable national framework and the actual installed equipment before relying on a compliance conclusion.
TM44 guidance explains inspection purpose and advice. It does not verify a provider’s accreditation, certify a particular company or guarantee that recommended works will reduce costs.
