A specialised form of commercial audit, school auditing builds on the same fundamental principals of commercial auditing in a highly sensitive environment.


With over 100 school audits under our belt, GHGP is highly adept at combining our commercial auditing package with the training and oversight required to work seamlessly in a school environment.


All of our auditors are working with children certified and have undertaken in-house school behaviour training modules which emphasise a no disruption to class and minimal student interaction auditing procedure.

We are the national specialists in identifying waste, leakage and unnecessary energy consumption in homes and proposing low cost high payback solutions to home owners and landlords 


Our energy auditors review lighting, air conditioning, refrigeration, curtains, blinds, water, insulation, chimneys and behaviour to provide a comprehensive set of solutions to reduce your home energy use.


A branch of commercial auditing, sports lighting auditing involves:

  • Assessing the current lighting technologies on site

  • Precise measurement of pole heights

  • Precise measurement of court or field dimensions

  •  Lighting design

Once collected, our auditor discusses the required level of illumination required, social, competition or broadcast and submits the data to our lighting design team to design the most optimal solution for your site. 


Commercial solar auditing for prospective commercial solar systems is a critical and specialised activity which can save thousands of dollars in cost overruns if done correctly.

GHGP’s commercial solar audits inspect both the supply and consumer side of your sites electrical grid, including transformers, MSBs, DBs, prospective inverter stations, data points, cable runs, roof sheeting and building structural capability.

With over 100 commercial solar audits completed, we can give you all the information your need to design the perfect system, or design it for you.


Our council auditing services give council entities the ability to assess their energy use across their entire portfolio of buildings and public spaces. g

A typical output of our comprehensive audits is a detailed facility or portfolio study in which we break down your current energy use habits, existing equipment on site, solutions for reducing your energy consumption and cost and the savings you can expect.
