Energy Audit Report

What is an Energy Audit Report?

An energy audit is an in-depth report of your site. It’s a practical step in identifying, quantifying and prioritising energy-saving opportunities. The report specifies areas of concern that could better accommodate energy efficiency. Once an auditor carries out a physical inspection of your site, they can identify energy consumption and wastage. A report will typically provide you with 10-20% of savings on your business’s annual utility spend.

Power Audit UK offer energy audit reports for commercial businesses. We have over 23 years of industry experience and have carried out assessments across the UK. These reports are an essential tool in reducing energy consumption, carbon footprints and to save on outgoing costs. Our comprehensive reports assess the feasibility of your energy efficiency measures. It also identifies whether you need a more detailed investigation into a leak.

Key Benefits of an Energy Audit?

Breakdown the key energy users on site, such as heaters and ventilation

Ensure the site owner is on the correct energy tariff

Examine the building’s energy saving measures, such as its insulation

Identify a range of energy and cost-saving opportunities

Make sure you are meeting the new DCP161 requirements

Obtain data from existing suppliers to assist in forming recommendations

Outline a prioritised plan of action

Provide comparable energy performance data from similar sites

Recommend cost-effective and free energy saving measures

Review the on-site energy management

Review the site’s energy supplier and their contract end dates

Review the site’s environmental capabilities and capacities

Review the staff’s behavioural attitude towards energy saving measures

How does it work?

An energy assessor would be required to carry out a physical inspection of your site. This would include an investigation of the property’s existing infrastructure. This would include its total building materials and supplementary units. From here, we’ll separate our compiled data into zones. Each zone of the building features its own purposes – such as an office area or production line. However, before this, we’ll measure the building itself. Then, once we have all the relevant data, we can calculate the energy baseline of a building of that size. The zones are then totalled and compared to this baseline. This determines whether your building is optimised for energy efficiency.

Power Audit UK’s energy audits are cost-effective, in-depth and accurate.

An energy audit report follows the completion of the audit. This investigative report is carried out, compiled and completed by our experienced assessor. The aim of the report provides a concise summarisation of the investigative findings. It is an extremely useful tool for understanding potential energy-saving opportunities. Thanks to Power Audit UK’s established methodology, our analysis results in an accurate assessment of your site.

What goes into a report?

The most basic report we offer at Power Audit UK is known as an Energy Performance Certificate (EPC). This focuses on the infrastructure and outlines improvements to energy efficiency. These identify key upgrades to things like heating, lighting and ventilation systems. Below you’ll find a very basic explanation of what one could involve:


In this space, Power Audit UK would detail the what. Such as the date we were appointed to review and identify the problem areas within the intended site. We would also outline our aims. Typically, these come from our client’s desires to reduce their energy consumption. Or their ongoing objectives to minimise the site’s C02 emissions.

Site Description

Here, we would explain the why, such as reasons for the business contacting us. We would also detail the number of staff who operate within the building and their working hours. This way, we can hone in on when equipment is more likely to be running and where conservations can be made. We would also specify what types of energy are used on-site and what the site’s general purpose is.

Energy Consumption and Cost Analysis

For the sake of conveying the relevant information to you, our example has split this section in two. However, this varies depending on the site in question and the designation period of time. It’s representative of the client’s utility consumption and cost information.

Electricity Usage

This section outlines the sites energy consumption. Although dates and times can vary, it breaks down consumption into units of energy (kWh) into Day and Night. However, the more data gathered the better. In such a situation, we would recommend installing an interval-metering system. With the data, we can observe the max demand needed – as well as the cost of the energy – and work out an average for the site.

Natural Gas Consumption

Much like Electricity Usage, this outlines the gas used in conjunction with the size of the site. It also breaks down and isolates specific zones that use more energy than others. We would work out an average and match this against the size of the site and whether savings can be made.

Energy Management

We would need to review the client’s existing Energy Managements system. After determining whether it is as effective as possible, we would outline pitfalls or suggest improvements. However, if the site requires a simplistic Energy Management system then alterations needn’t be made.

Summary of Recommendations

Typically, this table consists of 5 columns: 

 Recommendations: a clear and concise breakdown of the investment aim

Investment Cost Category: is the investment a low, medium or high cost?

 Payback Period (year): 1 year = 1, 6 months = 0.5

 Annual C02 Emissions Savings (tonne)

Predicted Annual Savings (broken into 2 columns):
 Energy (kWh)
 Cost (£)


Finally, your energy auditor would compile the gathered data. They would outline total energy and expenditure savings, as well as highlight a reduction of C02 emissions per annum. The conclusion provides a compelling argument for your site to take necessary action. Once you see all the benefits for you and your site, you would be hard-pressed to find a reason to repel change. If possible, the auditor would provide comparable data with other sites of a similar nature.
