United Kingdom HVAC Market Size & Share Analysis - Growth Trends & Forecasts (2025 - 2030)

United Kingdom HVAC Market Trends and Insights

Supportive Government Energy-Efficiency Incentives

The Boiler Upgrade Scheme has offered GBP 7,500 grants for both air-source and ground-source heat pumps since 2022, and the 2024 extension of the scheme confirmed long-term policy support. Complementary funding under the Social Housing Decarbonisation Fund and the Energy Company Obligation is unlocking finance across rental and low-income segments. Despite generous grants, uptake has lagged because installers are scarce and electricity remains pricier than gas in retail tariffs, limiting cost-parity for homeowners. Policymakers are exploring tax rebalancing to narrow the electricity-to-gas price gap, which would materially raise the return on investment for heat-pump retrofits.

Rising Demand for Energy-Efficient Devices

Public concern over climate change is high, yet awareness of heat-pump performance remains limited: a 2024 survey showed 70% of respondents knew little about the technology. Commercial buildings are moving quicker, adopting AI-enabled automation such as Johnson Controls’ Metasys 14.0, which has demonstrated 20% average energy savings in pilot sites. Variable-refrigerant-flow systems allow zone-level temperature management, and predictive maintenance driven by IoT sensors increases uptime while lowering service costs. These features are reshaping purchasing criteria toward lifecycle efficiency instead of upfront capital cost.

Construction Boom and Retrofit Wave

Nearly 80% of the 2050 residential stock already existed by 2025; therefore, retrofitting carries enormous weight. Government targets call for upgrading 20% of existing buildings to zero-carbon-ready status by 2030 ^{[2]International Energy Agency, “Buildings Sector Pathway,” iea.org}. London leads in retrofit volume, yet new-build momentum is strong in data centers, logistics hubs and mixed-use developments that specify low-carbon HVAC from the outset. Fragmented supply chains of thousands of SMEs complicate quality assurance, but innovative salary-sacrifice finance models and employer-backed loans are beginning to close funding gaps for homeowners.

UK Heat-Pump Boiler Replacement Mandates from 2026

Legislation requiring all new boilers to be hydrogen-ready within eighteen months is driving a strategic pivot across manufacturing and installation channels. Manufacturers are investing in hybrid systems that combine a small gas burner with a heat pump to hedge the uncertain direction of hydrogen infrastructure roll-out. The policy accelerates collaboration: British Gas announced a nationwide service partnership with NIBE in March 2025 to boost installer capacity ahead of the mandate.

High Upfront Cost of Efficient Systems

Heat-pump installations in 2024 typically ranged between GBP 10,000 and 15,000, against GBP 3,000-4,000 for a gas boiler replacement. Required envelope upgrades and electrical works can double project budgets, stretching payback periods even with grants. Electricity prices per kWh remained roughly three times higher than gas, suppressing operating-cost savings ^{[3]Heat Pump Association, “Unlocking Widescale Heat Pump Deployment,” heatpumps.org.uk}. Material price volatility, particularly for copper, has added further uncertainty for installers and end-users. Although zero-interest loans and employer schemes are emerging, awareness and administrative hurdles limit uptake.

Skilled-Labour Shortage for Installation and Maintenance

Only about 3,000 engineers were certified to fit heat pumps in 2024, well short of the 120,000-230,000 workers needed by 2030. Shortages inflate labour costs and delay projects, undermining consumer trust. Training programs such as the Enhanced Retrofit Fabric Improvement Training launched in Wales during 2024 are widening the talent pipeline, but scale remains insufficient. Industry is also lobbying for streamlined visas to attract qualified overseas technicians.

Segment Analysis

By Component: Services Accelerate Amid Equipment Complexity

Services accounted for 32.9% of 2024 revenue, a share projected to rise as system sophistication increases. The United Kingdom HVAC market size for services is expected to reach USD 1.25 billion by 2030, advancing faster than equipment. This surge is linked to sensor-rich installations that need commissioning, software updates and predictive maintenance. Equipment still holds the lion’s share because heat-pumps, VRF units and advanced chillers carry high capital expense. However, revenue is flattening as component prices face deflationary pressure once manufacturing scale improves. 

Growth in services is fuelled by smart-control deployments: Daikin’s 2025 Smart Control System enables plug-and-play integration but still demands professional configuration to optimise hydronic loops. Facilities are increasingly governed by performance-based contracts where energy savings are guaranteed, deepening the role of service providers. As a result, labour scarcity becomes a revenue bottleneck as much as an operational constraint, putting wage inflation pressure on the United Kingdom HVAC market.

By End-User Industry: Commercial Growth Outpaces Residential Dominance

Residential applications commanded 75.5% of 2024 revenue. Yet the commercial segment is forecast to grow at 7.5% CAGR, outstripping overall United Kingdom HVAC market growth. Data-center cooling is the prime driver: hyperscale campuses around London, Manchester and Edinburgh demand redundant, high-efficiency chillers that must run on low-GWP refrigerants. Hospitals and schools are also ramping investment to comply with stricter indoor-air-quality norms introduced after the pandemic. 

The United Kingdom HVAC market size for data centers alone is set to double by 2030, aided by AI workloads that raise heat densities. Pharmaceutical manufacturing is adopting adiabatic humidification and close-control air handling, opening white-space for niche OEMs. In contrast, residential retrofits hinge on grant mechanisms and smart-meter roll-outs that can monetise demand-response services.

By Installation Type: New Construction Momentum Builds Despite Retrofit Leadership

Retrofit installations held 61.2% of 2024 revenues, a natural outcome of the large existing housing stock. However, new construction is gaining share as builders pre-install low-carbon systems to comply with upcoming standards. Many developers now specify networked ground-source heat pumps linked to ambient-temperature loop grids in new estates, an approach that cuts upfront cost per dwelling by exploiting shared boreholes. 

Within retrofit, whole-house approaches that bundle insulation, windows and mechanical ventilation are growing. Yet fragmented contractor ecosystems slow scaling; a typical heat-pump job can involve four separate trades. Government pilot schemes that coordinate design, finance and installation under a single contract are beginning to show time-and-cost efficiencies, signalling a potential acceleration by the late-2020s.

By Capacity Range: Distributed Systems Drive Small-Scale Growth

Systems rated 5-20 kW captured the largest 32.1% share of the United Kingdom HVAC market size in 2024, matching the heat requirements of typical semidetached homes. Sub-5 kW units, often monobloc heat pumps suited for apartments, are expanding at 8.3% CAGR. These compact systems benefit from simplified permitting and do not always require major panel upgrades, making them attractive to urban renters and landlords. 

Smaller capacities also fit emerging demand-response programs: units equipped with smart inverters can modulate output to track grid frequency, earning revenue for building owners. Research has highlighted, however, that synchronized thermostat controls risk creating morning-peak surges, so utilities are piloting dynamic tariffs to stagger start-up cycles. At the opposite end, >200 kW plant room installations remain niche, with stable growth in hospitals and industrial sites.

Geography Analysis

England dominated installations in 2024, driven by high retrofit volumes in Southeast commuter belts and intense data-center construction around the M25 corridor. Scotland followed, leveraging abundant wind power that improves the carbon intensity of electric heating and thus the lifetime abatement value of heat pumps. The Scottish government’s more aggressive 2038 interim emissions target means grants and planning approvals arrive faster, attracting manufacturers to pilot hybrid heat-pump-hydrogen solutions. 

Wales exhibited rising activity after regional training centers opened in Swansea and Wrexham, narrowing the installer gap. Rural Mid-Wales and the Scottish Highlands still face higher transport costs for equipment and insufficient three-phase grid capacity, limiting uptake despite favourable climates. Northern Ireland lags owing to divergent building regulations and a smaller grant budget, yet cross-border interconnection projects promise better electricity prices that could unlock demand by 2028. 

Regional electricity tariffs, grid-carbon factors, and policy incentives together shape investment decisions. A homeowner in Cornwall may face higher peak tariffs but can join community solar-plus-battery schemes, while an office in Glasgow benefits from lower-carbon grid electricity that enhances corporate ESG metrics. Local authorities adopting area-wide heat-decarbonisation plans are steering bulk procurement, which is expected to compress margins but speed diffusion of standardised heat-pump kits.
