Our Corporate Social Responsibility (CSR)

We’re proud of our all-in work environment and believe in a fair go for everyone. While our wider industry does struggle with gender balance across roles, we stay accountable through the Workplace Gender Equality Agency (WGEA). As a result, our gender pay gap is well balanced and with regular reporting we continue to contribute to improved gender equality outcomes in Australian workplaces. Learn more
We encourage Indigenous Australians to apply for all positions. Our inclusive environment is a vital part of our success and we support the self-determination of Indigenous people as a path to strong communities.

We actively minimise our environmental footprint with our everyday actions: increased energy efficiency, lean business processes, reduced resource consumption and waste elimination. We are part of the FluoroCycle initiative which helps reduce the buildup of landfill mercury by recycling waste lighting. We also have a 5.5 star NABERS rating for our Sydney headquarters and continue to lean into greening opportunities. Learn more

If you’re a building owner, facility or asset manager, audits are a vital tool for improving profit and efficiency. Your critical building services and infrastructure are a significant capital investment so regular auditing is a key element of strategic asset management. Effective maintenance programming, operational and capital expenditure planning give you grounds to better manage your assets, compliance, safety, risk and reliability. Get a heads-up for any potential failure points and be proactive rather than reactive. Audits are a natural part of the life cycle assessment of each asset and relevant infrastructure.
Your audit provides a complete building safety and compliance review referencing the relevant Australian building codes and standards. As part of any built environment audit, we identify existing building safety and building compliance issues. As a building owner, meeting your duty of care means pinpointing current hazards and risks that could potentially reduce the health, safety and welfare of building occupants and maintenance staff. Prevention of exposure to a high degree of potential future risks directly impacts your productivity and profitability.
Grosvenor audits offer independent compliance, risk, condition and financial planning services. Our audits are effective, efficient, high-quality and tailored to your needs. We offer four levels of auditing services, from a detailed asset validation to a comprehensive assessment of technical services. We offer audits on a range of different building services: fire, HVAC and refrigeration, BMS, electrical, solar, plumbing and safety services. We can also assess and report on building fabric within your property.
An audit of your building services gives you data to determine the current state of all your building assets and services or an audit of property plants and equipment. It’s an essential starting point for short and long-term maintenance and capital expenditure budgets. This tool allows you to project viable and economical solutions now and in the future.
With a level 3 or 4 audit of your properties, you’ll gain a full review of system operation, get advice on your current energy consumption and guidance around strategic improvement and initiatives. We do this by reviewing your existing building services to find opportunities for optimisation. This focuses on reduced running costs and potential upgrade solutions for a better ROI. Audit reporting assists building owners to discover how their services operate and are controlled, make more informed decisions and strengthen planning. Learn more


BEEC stands for Building Energy Efficiency Certificate. Firstly, this document indicates your building’s energy saving performance using a NABERS energy rating. Secondly, it confirms that a tenancy lighting assessment (TLA) is needed, which measures the lighting performance within office tenancies. To obtain a BEEC, both a current NABERS rating and TLA need to be active for your building.
It all depends on your building type. If you’re advertising or leasing over 1,000 square metres of cumulative office space, it’s likely your building requires a BEEC. If you’re unsure, a CBD NABERS assessor can advise you.
A NABERS rating is a standardised efficiency rating conducted on multiple building types. The most common ratings are energy saving and water performance with other rating types like indoor environment (IE) and waste also growing in demand. NABERS ratings are usually performed on office buildings and shopping centres. However, the scope of buildings this rating can now grade includes apartments, data centres, hotels, public hospitals and residential aged care and retirement living.
BEECs are only valid while both a valid NABERS energy rating and TLA are active for your building. When complete, a NABERS rating is valid for up to 12 months but you only need to renew your TLA every five years. In practice, a BEEC is only valid for a year at a time.
It’s true, you may not need a rating if your property is NOT an office building. However, a NABERS rating is a standardised method that measures your building performance and provides a nationally recognised tool for comparing your performance against similar energy efficient buildings across the country. By actively maintaining your NABERS energy rating, you confirm your company’s active commitment to reducing its environmental impact. At the same time, you set a reliable benchmark that you can constantly improve on and potentially save thousands on utility costs. NABERS ratings also contribute valuable points to global sustainability performance reports such as Global Real Estate Sustainability Benchmark (GRESB). Learn more
