There is no flat price for an energy audit in Bangladesh, and any quote given without seeing the plant is a guess. The fee follows the size of the facility, how many utilities are in scope and how deep the audit goes. At Hexa Engineering we visit first, then give you a fixed fee in writing before you commit to anything.
What decides the price of an energy audit
Six things move the fee more than anything else:
- Plant size and complexity. A single-building apparel unit and a multi-unit textile complex with its own boilers and captive power are different jobs. More buildings, lines and large loads mean more to measure.
- Utilities in scope. Electricity alone is the simplest case. Adding natural gas, steam, compressed air, chilled water, fuel oil or process water adds measurement points and analysis for each one.
- Audit level. A walk-through (Level I), a measured audit (Level II) and an investment-grade audit (Level III) are different scopes. Our energy audit service explains what each covers.
- Measurement effort. Power loggers on the major loads, thermal imaging, flue gas analysis, compressed air leak surveys and power quality recording all take instrument time on site. A plant with good sub-metering can need less.
- Number of sites. Several similar sites can often be scoped together, because the method and templates carry over.
- Reporting requirements. A report that must satisfy SREDA, a lender or a buyer's sustainability programme needs more documentation than an internal screening.
The three audit levels and how they change the fee
| Level | What it covers | Typical use | Effort |
|---|---|---|---|
| Level I | Site walk-through and review of utility bills. Finds obvious losses and no-cost measures. | Screening, and deciding whether a detailed audit is worth doing | Lowest |
| Level II | Loggers on the major loads plus thermal, flue gas, compressed air and power quality surveys. Every saving is calculated from measured data. | Most factory audits, SREDA compliance | Medium |
| Level III | Detailed engineering and financial analysis of capital projects. | Loan applications and board approvals | Highest |
How long an audit takes
A scoping visit takes one day. A full instrumented audit of a mid-sized plant usually takes three to six weeks, depending on how many utilities are in scope. Measurement is done on live equipment during normal running, so production does not stop. Time on site is a large part of the cost, which is why the scope should be fixed before the work starts.
What you receive for the fee
- A measured energy baseline for the plant
- A ranked list of savings measures, each with its saving in kWh, taka and tonnes of CO2e, its investment and its payback
- No-cost and low-cost measures first, so you can start saving before any capital is spent
- A report signed by a certified energy auditor, carrying the auditor's name and certification number

Is an energy audit worth the money?
The report ranks every measure by payback, so you decide what to do and in which order. Many audits find measures such as compressed air leaks, boiler tuning and power factor correction that pay back within months.
For larger projects, Bangladesh Bank's Green Transformation Fund (GTF) has supported energy-efficiency and renewable-energy projects at export-oriented textile and leather factories. Terms change, so check the current rules with your bank. An investment-grade audit is the document lenders ask for, and we help prepare GTF and green finance documentation.
Comparing quotes fairly
Two audit quotes can differ a lot because they are not the same job. Before you compare prices, ask each firm:
- Is the auditor certified, and will the certification number appear on the report?
- Are savings calculated from measured data, or estimated from nameplate ratings?
- Which buildings and utilities are included?
- Does the report show the payback of every measure?
- Is help with implementation or verification of savings included?
How to get a fixed fee for your plant
- Tell us about the plant. Facility type, location, approximate monthly electricity and gas bills, and the boilers, generators and large machines you run. The energy audit checklist lists what is useful to have.
- Scoping visit. One day on site to see the plant and agree the scope.
- Fixed fee in writing. You receive it after the visit and before any commitment.
- The audit. Measurement, analysis, and a report with ranked measures.
