The Professional Services subdivision's performance is largely linked to overall economic conditions, often determining business confidence and capital expenditure. Over the past few years, greater business profit and rising capital expenditure by the public sector have supported subdivision demand. However, construction projects that were delayed or cancelled because of surging construction expenses and labour scarcity adversely impacted several industries, including architectural services and engineering consulting. This factor has dampened overall subdivision performance, contributing to revenue only growing by an annualised 1.0% through the end of 2024-25 to $324.5 billion. This trend includes a 1.6% rise in the current year, as the rise of AI, particularly generative AI (genAI) and sustainability trends, enables higher value-added service offerings. The professional services subsector is shifting towards tech-oriented strategies. Service providers are incorporating advanced tech solutions like AI-assisted data analysis and genAI into operations. This technological integration improves efficiency and service delivery and facilitates innovation. GenAI has also enabled higher precision in services like design, consulting and accounting, redefining service delivery. High-value, tech-oriented services command premium pricing and have contributed to revenue growth. However, these come with inherent challenges. Requiring specialised skills leads to increased operational costs, including training expenses and investments in technology. The increased remuneration needed to attract and retain talent has escalated costs and exerted pressure on profit margins over the past few years. The Professional Services subdivision is forecast to grow over the next few years, driven by sustainability trends and enhanced regulations. As the focus on renewable energies intensifies, demand for engineering consultants equipped with specialist knowledge is set to accelerate. The need for mandatory climate disclosures and ESG compliance also presents growth potential for accounting and advisory firms. Technology is another determining factor that will dictate service offerings' operations, quality and variety. As demand for tech-oriented solutions intensifies, service providers will be more inclined to invest in tech-related expertise, adding value to their service offerings and enhancing their competitive edge in the market. These forces are why subdivision revenue is forecast to expand at an annualised 2.4% through the end of 2029-30, to $365.5 billion.
