Ventilation and Air Conditioning Market Report – UK 2025-2029

Market Summary

The UK ventilation and air conditioning (VAC) market is valued at around £1.42 billion in 2025, showing modest growth of 2% on the previous year. Demand remains steady despite a weak housing sector, supported by ongoing investment in non-residential construction and increasing focus on indoor air quality and energy efficiency.

Air conditioning systems account for just over half of market value, while ventilation and accessories make up the remainder. Market growth to 2029 will be driven by tighter building regulations, the Future Homes Standard, and the transition to low-carbon and hybrid systems across both residential and commercial buildings.

Report Overview

The UK Ventilation and Air Conditioning (VAC) Market Report 2025–2029 examines market structure, performance, and future prospects across the residential and non-residential sectors. The report analyses trends in market value, product segmentation, distribution, imports and exports, and the wider economic and regulatory context affecting demand.

Key themes include the growing impact of building regulations and the Future Homes Standard, which continue to drive specification of energy-efficient and low-carbon ventilation and cooling systems. The market is also shaped by climate change, with higher temperatures increasing demand for comfort cooling, and by the focus on indoor air quality, influencing uptake of mechanical and hybrid ventilation systems.

Other issues explored in the report include the imbalance between residential and non-residential demand, the sector’s reliance on imports, and ongoing skills shortages across installation and manufacturing. Despite near-term pressures from a weak housing market and cost inflation, the outlook remains positive, with gradual market expansion forecast through to 2029, supported by regulatory change, sustainability goals, and continued investment in energy-efficient building technologies.

Market Size

The UK ventilation and air conditioning (VAC) market is estimated to be worth around £1.42 billion at manufacturer selling prices (MSP) in 2025, representing modest growth of approximately 2% compared with 2024.

Market Analysis

The UK ventilation and air conditioning (VAC) market continues to show steady but subdued performance, reflecting broader trends in the construction industry. While residential demand remains weak, constrained by limited new housing activity and declining RMI expenditure, non-residential investment—particularly in data centres, healthcare, and education—continues to provide underlying support.

Growth is being sustained by tightening building regulations, increased focus on energy efficiency and indoor air quality, and the transition to low-carbon and hybrid systems.

The market remains import-reliant and highly competitive, with rising production costs, labour shortages, and economic uncertainty presenting ongoing challenges. Nevertheless, medium-term prospects are positive, with gradual market expansion forecast through to 2029 as sustainability legislation and modernisation within the built environment continue to underpin demand.

Forecast 

Market forecasts indicate a period of gradual, steady growth, supported by regulatory change, energy-efficiency targets, and sustained investment in non-residential construction. The market is expected to remain stable, with moderate expansion as economic conditions improve.

Key Companies Mentioned in the Report

The UK ventilation and air conditioning (VAC) market is supplied by a mix of major international manufacturers and established UK-based specialists. In the ventilation sector, market leadership is concentrated among the Volution Group, Genuit Group, and Zehnder Group, which together account for around half of total market value. These groups operate multiple well-known brands including Vent-Axia, Nuaire, Domus Ventilation, and Greenwood Airvac.

Other notable ventilation suppliers include Airflow Developments, EnviroVent, Systemair, Swegon Air Management, Elta Fans, FläktGroup UK, Titon, Trox UK, and Vectaire.
The air conditioning market is more fragmented and dominated by major overseas manufacturers such as Daikin, Mitsubishi Electric, Carrier, Trane, Johnson Controls–Hitachi, Panasonic, LG, and Samsung, supported by UK operations including Airedale, Aermec UK, and TEV.

Across both sectors, competition is shaped by technological capability, product efficiency, and distribution reach, with increasing emphasis on low-carbon solutions and integrated heating, cooling, and ventilation systems.

Market Trends and Influences

The market is shaped by stricter building regulations and the forthcoming Future Homes Standard, driving demand for energy-efficient and low-carbon VAC systems. Economic pressures such as cost inflation and supply chain disruption continue to affect margins, while growing awareness of indoor air quality and sustainability supports investment in modern mechanical solutions. Technological advances—including smart controls, hybrid heat recovery, and system integration—are further influencing product development and specification.

Product Categories

The UK ventilation and air conditioning (VAC) market comprises three main product categories: ventilation systems, air conditioning equipment, and VAC accessories.

Air conditioning represents the largest share of market value, driven by demand for packaged, split, and hybrid systems offering improved energy efficiency and comfort cooling.

Ventilation products account for just under a quarter of market value, with growth supported by the wider adoption of mechanical and heat recovery systems (MVHR, MEV, dMEV) in response to tighter building regulations.

Accessories such as ducting, filters, and controls make up the remainder of the market, influenced by sustainability requirements and the emphasis on indoor air quality and system efficiency.

Distribution Analysis

Distribution channels in the UK ventilation and air conditioning (VAC) market vary by product and end-use sector. Residential ventilation products are primarily supplied through trade distributors, merchants, and electrical wholesalers, with additional sales via retail and online outlets. In the non-residential sector, supply is more commonly direct to contractors or specifiers, particularly for larger or bespoke systems.

For air conditioning, packaged units are distributed mainly through specialist trade distributors, while central plant systems are sold predominantly direct to contractors and commercial clients. The overall market remains characterised by a mix of direct supply and specialist trade channels, reflecting the diversity of product types and project requirements.

End Use Analysis

The non-residential sector accounts for the majority of UK ventilation and air conditioning (VAC) demand, representing around three-quarters of market value. Key applications include data centres, offices, healthcare, education, and logistics facilities, where energy efficiency and indoor air quality remain primary drivers.

The residential sector makes up the remaining share, split between new-build housing and RMI activity.
