$3.86 billion is the projected size of the UK HVAC market by 2034, up from $2.72 billion in 2025 and $2.83 billion expected in 2026.
3.96% annual growth is being driven by net-zero policies, wider heat-pump adoption, boiler replacements and demand for more energy-efficient heating, cooling and ventilation systems.
£7,500 grants under the Boiler Upgrade Scheme and rules barring fossil-fuel heating in new homes from 2025 are accelerating the shift toward low-carbon and hybrid systems.
30% of UK greenhouse-gas emissions come from buildings, while roughly 28 million dwellings still rely largely on gas heating, leaving a large retrofit market but also high upfront-cost and labor constraints.
58.5% of the market came from residential demand in 2025, with equipment leading current sales and HVAC services forecast to grow faster at a 7.4% CAGR as systems become more complex.
As policy shifts away from hydrogen, can the UK solve its critical shortage of skilled engineers to meet its 2028 heat pump goal?
With heat pump installations falling, are high costs and electricity prices making the UK's green heating targets unachievable for average homeowners?
While the UK champions heat pumps, is the national electricity grid truly prepared for the massive demand surge on the coldest winter days?
Decarbonizing the UK HVAC Market: 2026 Growth, Policy, and Technology Outlook
Overview
The UK HVAC market is seeing strong growth in 2026, fueled by increasing urbanization, more commercial buildings, and a greater focus on indoor air quality. Concerns about poor air quality and the need for precise humidity control are pushing up demand for advanced HVAC systems. At the same time, strict government standards on refrigerant use and energy efficiency are reshaping the market and driving innovation. These factors are working together to transform the HVAC sector, making it more responsive to both environmental needs and new regulations, while encouraging the adoption of smarter, more efficient technologies.
