Plumbing, heating, and air conditioning installation is a cornerstone of Dubai's construction and building services sector. The global mechanical, electrical, and plumbing (MEP) services market reached USD 172.46 billion in 2025 and is projected to hit USD 239.41 billion by 2030 at 6.78% CAGR,¹ with HVAC representing the largest application area in the UAE driven by extreme climate conditions and large-scale commercial development.

The global HVAC and plumbing market alone is projected to grow from USD 18.51 billion in 2025 to USD 26.02 billion by 2033 at 4.35% CAGR.² Saudi Arabia leads the Middle East market, with the UAE representing approximately 0.64% of the global HVAC and plumbing market and growing rapidly due to luxury residential and large commercial properties demanding high-performance systems.²

This parent activity (4322) covers the full scope of MEP installation, from plumbing and sanitary systems through heating and ventilation to air conditioning. Sub-codes (4322.92, .93, .97, .98) carve out specific specialisations.
