# England's Heat-Pump and Air-Conditioning Installation Outlook

## Executive Summary

- **Fast Growth From A Small Base**: The UK installed about **98,000 heat pumps in 2024**, up **56%**, while more than **60,000 MCS-certified heat pumps** were installed in 2025. Yet heat pumps still serve only about **1% of UK homes**. Growth is real, but market participants should plan for staged expansion rather than assume policy targets will automatically be met. [21] [67]
- **Retrofit Is The Largest Prize**: About **21.2M English households, or 86%**, used gas-fired main heating in 2023-24. This large installed base makes boiler replacement, rather than new construction, the decisive market. Suppliers should target replacement events with heat-loss assessment, emitter upgrades, financing and grant processing in one offer. [48]
- **Policy Supports Demand But Does Not Remove Economics Risk**: The Boiler Upgrade Scheme offers **GBP7,500** for qualifying hydronic heat pumps, and the Warm Homes Plan allocates about **GBP2.7B** to expand the scheme through 2029-30. However, standard-tariff heat-pump running costs can still be slightly above those of a new gas boiler because electricity costs roughly four times as much per unit as gas. Installers should sell verified whole-system performance, not equipment efficiency alone. [15] [62] [21]
- **Cooling Creates A Second Demand Curve**: Only about **3% of UK homes** currently use air conditioning, consuming approximately **0.3 TWh**, but published scenarios put 2050 adoption at **5%-32% of English homes** or **10%-40% of UK homes**, depending on assumptions. Hotter summers will increase demand, but Part O makes passive overheating mitigation the first response in new English homes. [93] [17] [75]
- **Reversible Systems Gain Strategic Value**: Air-to-air heat pumps combine heating and cooling, while 2025 planning changes made domestic deployment easier and the Warm Homes Plan introduced **GBP2,500** support for eligible air-to-air systems. Reversible systems are particularly relevant to flats, small homes and properties without wet central heating, although domestic-hot-water provision must be addressed separately. [15] [114]
- **The 2030 Aim Requires Exceptional Acceleration**: The current Warm Homes Plan aims for more than **450,000 annual heat-pump installations by 2030**. Moving from the 2025 floor of 60,000 MCS-certified installations to 450,000 would imply roughly **49.6% annual growth for five years**, with an important scope difference between the two figures. Businesses should use base, growth and policy-fulfilment scenarios rather than one forecast. [15] [67]
- **Installation Quality Is A Market Constraint**: A recent **742-home** demonstration achieved average air-source efficiency of about **293%**, and **85%** of participating households would recommend a heat pump. An older trial achieved only **2.45** average seasonal performance for air-source systems, showing how sizing, controls, emitters and commissioning can determine the customer outcome. Scale quality assurance before scaling lead generation. [81] [80]
- **Low-GWP Refrigerants Become A Procurement Requirement**: Great Britain already bans certain high-GWP products, including single-split systems containing less than 3 kg of refrigerant with GWP of 750 or more from 2025. A steeper HFC phase-down from 2027 remains a proposal, not current law. Buyers should favor low-GWP platforms while avoiding procurement decisions based on unadopted rules. [41] [39]
- **The Winning Offer Is An Integrated Energy Service**: Smart tariffs, automated controls, solar PV and storage can reduce cost and peak demand, but headline savings come from small trials and are not universal. Providers should bundle design, financing, controls, monitoring and aftercare while guaranteeing only modelled outcomes supported by the property assessment. [117] [98]

The central conclusion is that installations in England will rise, with heat pumps growing faster than conventional air conditioning. The trajectory will be uneven: new-build standards create dependable demand, grants support owner-occupied retrofits, and hotter summers support cooling, but electricity prices, customer reluctance, installer quality and grid constraints prevent a simple straight-line forecast.

## A 21.2M-Home Gas Base Makes Retrofit The Core Prize

Market definitions produce very different headline values. Proprietary estimates put the UK commercial HVAC market at **USD1.94B in 2025**, rising to **USD2.62B in 2030** at a **6.14% CAGR**. A broader UK HVAC systems estimate values the market at **USD6.95B in 2023**, rising to **USD9.08B by 2030** at **3.3% CAGR**. A separate heat-pump estimate projects **USD5.21B in 2026** to **USD8.87B in 2031**, an **11.24% CAGR**. These are not directly comparable because they cover different equipment, services, end users and forecast years. [8] [37] [33]

| Market lens | Published starting value | Published outlook | Decision use |
|---|---:|---:|---|
| UK commercial HVAC | USD1.94B, 2025 | USD2.62B by 2030; 6.14% CAGR | Commercial sales and service planning |
| UK HVAC systems | USD6.95B, 2023 | USD9.08B by 2030; 3.3% CAGR | Broad equipment-market context |
| UK heat pumps | USD5.21B, 2026 | USD8.87B by 2031; 11.24% CAGR | Directional low-carbon heating growth |
| English gas-heated households | 21.2M, 2023-24 | No single official conversion forecast | Retrofit addressable base |

The more reliable operating metric is the replacement pool. England had approximately **21.2M gas-heated households** in 2023-24, while the UK has historically installed around **1.7M fossil-fuel boilers a year**. Heat pumps therefore do not need immediate mass conversion to support a large installation and service industry; they need to capture a growing share of normal replacement decisions. [48] [51]

Three segments should be treated separately. New homes increasingly become low-carbon-heating projects by regulation. Owner-occupied retrofits respond to grants, lifetime cost and disruption. Commercial buildings respond to cooling need, asset value, energy performance and the replacement cycle for larger systems. Private-rented homes remain harder because landlords fund the installation while tenants receive much of the comfort and bill benefit.

The decision-ready insight is to size local opportunities from boiler age, property archetype, tenure and cooling exposure, not from a national revenue headline. A company focused on England should build separate propositions for new-build developers, gas-boiler replacement, off-grid homes, commercial HVAC renewal and cooling-led reversible systems.

## 2025 Sales Confirm Momentum, Not Target Attainment

Heat-pump activity accelerated across several different measures. The CCC reports **98,000 UK installations in 2024**, up **56%** from 2023. In 2025, Heat Pump Association members reported **125,037 factory-gate sales**, including **110,353 hydronic units**, a **27%** increase. MCS recorded more than **60,000 certified installations**. The figures differ because sales are not installations, MCS excludes non-certified work, and BUS covers only eligible retrofits in England and Wales. [21] [66] [67]

| Metric | Period | Reported volume | What it measures |
|---|---|---:|---|
| UK heat-pump installations | Calendar 2024 | 98,000 | CCC deployment estimate |
| UK heat-pump sales | Calendar 2025 | 125,037 | HPA factory-gate sales |
| UK hydronic heat-pump sales | Calendar 2025 | 110,353 | HPA subset of sales |
| MCS-certified heat-pump installations | Calendar 2025 | More than 60,000 | Certified commissioned systems |
| BUS applications | Apr 2024-Mar 2025 | 38,412 | England and Wales scheme demand |
| BUS redemptions | Apr 2024-Mar 2025 | 25,712 | Grants completed and redeemed |

The Boiler Upgrade Scheme is a useful case study in demand elasticity. After the grant increased to GBP7,500, average monthly applications rose, and Scheme Year 3 recorded **38,412 applications**, **25,712 redemptions** and about **GBP189.7M** paid. The mechanism is straightforward: reducing upfront cost moves some households from interest to purchase, but the difference between applications and redemptions shows that survey, eligibility, financing and project-delivery friction remain. [52]

The long-run gap is still large. The Warm Homes Plan aims for more than **450,000 annual installations by 2030**. The CCC's Balanced Pathway similarly calls for nearly **450,000 annual installations in existing homes by 2030**, rising to about **1.5M by 2035**, with roughly half of homes heated by heat pumps by 2040. These are transition pathways rather than sales forecasts. [15] [16]

The implication is a positive but bifurcated outlook. A sustained 15%-25% annual rise would create a sizeable installer and service market but leave deployment far below the 2030 policy aim. Approaching the aim requires grant continuity, tariff reform, new-build enforcement, much greater customer conversion and a rapid increase in qualified delivery capacity.

## GBP7,500 Grants And New-Build Rules Reshape Demand

England's policy environment is now more supportive than in the early BUS years. The Warm Homes Plan commits approximately **GBP2.7B** to BUS through 2029-30 and retains **GBP7,500** support for qualifying hydronic heat pumps. It also introduces **GBP2,500** support for eligible air-to-air systems, important because reversible units can address both heating and cooling. The broader plan identifies **GBP15B** of public investment, although not all of it is available to individual heat-pump purchasers. [15] [54]

The Future Homes and Buildings Standards establish low-carbon heat and high energy performance as the direction for new English buildings. New build is strategically attractive because emitters, pipework, insulation and plant space can be designed around a heat pump rather than retrofitted. In 2025, new homes represented **28% of MCS-certified heat-pump installations**, illustrating how standards can create a more dependable channel than voluntary retrofit. [85] [67]

Economics remain property-specific. The Energy Saving Trust gives an indicative air-source installation cost of about **GBP11,000**, while government guidance says households may still pay approximately **GBP6,500-GBP11,500** after grant support when associated works are included. A simple GBP11,000 minus GBP7,500 calculation is therefore misleading: cylinders, radiators, pipework, electrical work and fabric improvement can materially change the project. [62] [28]

Running cost is the main contradiction in the policy case. A well-designed heat pump commonly supplies about three units of heat per unit of electricity, but electricity remains roughly four times the unit price of gas. On standard tariffs, an efficient heat pump can consequently cost slightly more to run than a new gas boiler. Smart tariffs, eliminating the gas standing charge and improving seasonal performance can reverse that result; oil, direct-electric and LPG replacements generally offer a stronger operating-cost case than recent gas boilers. [21] [62] [61]

The recommendation is to make every quotation a whole-home business case with a heat-loss calculation, expected seasonal performance, tariff assumptions, radiator and pipework scope, grant value and sensitivity analysis. Selling a nominal COP without these elements creates financial and reputational risk.

## Cooling Adoption Could Reach 5%-32% By 2050

Domestic air conditioning remains a low-penetration but potentially fast-growing category. The Energy Demand Research Centre cites a NESO estimate that approximately **3% of UK homes** currently use air conditioning, consuming around **0.3 TWh**. UKERC scenarios put English household adoption at **5%-32% by 2050**, while a newer UK-wide study gives **10%-40%**. The disagreement reflects uncertain weather, incomes, social norms, building design, technology costs and whether passive measures reduce the need for mechanical cooling. [93] [17]

The Department for Energy Security and Net Zero's housing analysis estimates that approximately **20% of English homes** already experience overheating. Higher summer temperatures, more home working, dense urban development, large glazed areas and highly insulated homes that retain unwanted summer heat all increase cooling exposure. However, cooling adoption will remain regionally and socially uneven, with London, South East England, urban flats and higher-income households likely to move first. [12] [11]

Approved Document O provides the counterweight to mechanical cooling. It requires overheating mitigation in new English residential buildings. External shading, solar-control glazing, secure ventilation, reflective surfaces and building orientation can reduce cooling loads without adding electricity demand or refrigerant leakage. Active cooling should follow, rather than replace, these measures. [75] [76]

The most important product convergence is the reversible air-to-air heat pump. A single system can provide efficient shoulder-season heating and summer cooling, and 2025 permitted-development changes removed the one-metre boundary rule, increased the permitted outdoor-unit size from **0.6 to 1.5 cubic metres**, and allowed two units at detached houses, subject to the updated MCS sound calculation. This reduces planning friction while keeping a **37 dB** sound criterion. [111] [114]

For suppliers, the opportunity is not simply "more air conditioning." It is low-load building design plus efficient, low-GWP reversible equipment where residual cooling demand remains. That approach reduces peak power, avoids oversizing and aligns comfort sales with decarbonisation.

## Low-GWP Refrigerants And Smart Systems Define The Product Shift

Air-source hydronic systems dominate the near-term heating opportunity because they can replace boilers while retaining a wet distribution system. Ground-source systems offer stable performance but face land, drilling and capital constraints. Air-to-air systems are cheaper and reversible but do not normally supply domestic hot water. Hybrid systems reduce peak electrical requirements but retain fossil-fuel dependence. No one architecture fits every English building.

Refrigerants are becoming a product-platform decision. Current Great Britain rules cap HFC supply for 2024-26 at **31% of the 2015-19 baseline** and ban specified high-GWP equipment. From 2025, new single-split systems containing less than 3 kg cannot use refrigerant with GWP of 750 or more. Work on stationary refrigeration, air conditioning and heat-pump equipment containing F-gas requires the appropriate individual qualification. [39] [41] [40]

Defra has consulted on reducing the quota to **16.2% in 2027-29** and **10.3% in 2030-32**, eventually cutting HFCs by **98.6% by 2048**. These figures are proposed, not enacted. Nevertheless, they create a strong direction toward R290 and other low-GWP alternatives, better leak prevention and technician training. Product buyers should model serviceability, flammability controls, spares and engineer competence alongside headline efficiency. [39]

Controls and renewable integration form the second shift. The Heat Pump Ready programme found automated participation in flexibility events reached **98%**, compared with **24%** for manual participation. One project reported that combining heat pumps with solar PV, batteries and flexible tariffs could reduce heating bills by **61%**, but the report explicitly notes small samples and laboratory elements. An average 3.5 kWp solar array costs around **GBP6,100**, while a battery can add **GBP5,000-GBP8,000**, so the integrated system is not automatically the best investment for every home. [117] [118]

The practical priority is "smart-ready" rather than "maximum equipment." Specify weather compensation, monitoring, demand-response capability and interoperability first. Add PV, batteries or thermal storage where load shape, roof suitability and tariff value justify them.

## Daikin, Vaillant, Octopus And Local Installers Compete Differently

The market spans multinational HVAC manufacturers, boiler brands moving into heat pumps, energy retailers, merchants and thousands of local contractors. HPA members include Baxi, Bosch Thermotechnology, Carrier, Centrica, City Plumbing, Daikin, Dimplex, E.ON and other major participants. FETA represents more than **400** manufacturers, suppliers, installers and contractors across heating, ventilation, controls, refrigeration and air conditioning. [90] [56]

| Value-chain position | Representative players | Competitive basis |
|---|---|---|
| Global HVAC and reversible systems | Daikin, Mitsubishi Electric, Panasonic, Samsung, Carrier | Product range, refrigerant transition, installer support and commercial capability |
| Heating brands moving beyond boilers | Vaillant, Baxi, Bosch | Existing installer relationships, hydronic expertise and UK production |
| Ground-source specialists | Kensa | Shared ground loops and difficult-property solutions |
| Vertically integrated energy services | Octopus Energy, Centrica, E.ON, EDF | Tariffs, finance, lead generation, installation and aftercare |
| Distribution | Wolseley, City Plumbing | Stock availability, trade relationships, training and spares |
| Local specialists | Regional HVAC and renewables contractors | Survey quality, responsiveness, reputation and maintenance |

Vaillant illustrates the manufacturing transition. It invested in a Derbyshire heat-pump production line, using an established heating brand and installer base to move from boilers toward low-carbon hydronic systems. Baxi has similarly publicised ambitions to build substantial UK heat-pump capacity. The mechanism is channel conversion: companies with trusted heating brands can retrain existing engineers and cross-sell controls, cylinders and service. [18] [33]

Octopus Energy represents a different case. Its proposition links equipment, installation and electricity tariffs rather than selling the heat pump as a stand-alone appliance. This can lower customer acquisition friction and improve operating economics through time-of-use pricing, but it also places design, installation and aftercare risk with one provider. That model competes on delivered heat cost and customer experience, not only equipment specifications. [90] [117]

Local firms remain strategically important because installation is property-specific. Durham Air Conditioning, for example, markets air-conditioning installation, air-source heat pumps, ventilation, refrigeration and repairs, illustrating how regional contractors bundle installation with maintenance across adjacent technologies. This local-service model can win on trust and response time but needs MCS, F-gas competence, financing partnerships and digital monitoring to compete with integrated national providers. Durham Air Conditioning

Reliable public market shares are not available. Vendor estimates suggest air-source systems dominate UK heat-pump revenue, but procurement decisions should be based on installed performance, warranty support, refrigerant platform, installer coverage and total service cost rather than an unverified share ranking.

## High Power Prices And Poor Design Can Break The Case

The strongest counterevidence to an effortless heat-pump boom is consumer intent. In spring 2025, **79%** of UK adults had heard of air-source heat pumps, but only **27%** said they knew a lot or a fair amount. Among owner-occupiers, **26%** were likely to install one at their next heating replacement, while **45%** were unlikely. Awareness therefore no longer equals willingness. Cost, disruption, outdoor-unit space, uncertainty and trusted advice remain conversion barriers. [107]

The Electrification of Heat project provides a balanced performance case study. Across **742 installations** in varied UK homes, air-source systems averaged roughly **2.93 seasonal efficiency**, and **85%** of participants would recommend the technology. The trial supports technical feasibility across common property archetypes rather than the claim that every home can be converted without modification. [81]

The older government field trial explains why quality control matters. Its air-source systems averaged **2.45**, while ground-source systems averaged **2.82**, and major resizing produced more improvement than minor adjustments. The divergence between older and newer trials suggests that products and practice have improved, but it also confirms that poor heat-loss calculation, high flow temperatures, undersized emitters, microbore pipe constraints and weak commissioning can destroy both efficiency and confidence. [80]

| Risk | Mechanism | Early-warning metric | Mitigation |
|---|---|---|---|
| Running-cost disappointment | High electricity-to-gas price ratio and low seasonal efficiency | Metered SPF and annual GBP cost | Performance model, smart tariff and post-install monitoring |
| Installation bottleneck | Certified design and commissioning capacity grows slower than demand | Jobs per qualified team; survey-to-install time | Training, standardised design and staged geographic growth |
| Cooling peak | Heatwaves concentrate compressor load | Summer system peak and local feeder constraints | Passive cooling, shading, thermal mass and demand response |
| Refrigerant obsolescence | HFC quota and product bans change supply and service cost | Refrigerant availability and GWP exposure | Low-GWP platforms and technician certification |
| Policy slippage | Grants or standards change | Applications, redemptions and confirmed budgets | Avoid a plan dependent on one subsidy |
| Customer harm | Poor sizing, controls or aftercare | Complaints, call-backs and SPF below model | MCS processes, independent commissioning and warranties |

Grid risk is manageable but not negligible. NESO says peak-demand flexibility must grow four to five times by 2030, while residential demand responsive to time-of-use tariffs needs to rise from about **1.5% to 8%-9%**. Heating drives winter demand; cooling can create concentrated summer peaks. The recommendation is to make connected controls, pre-heating or pre-cooling and flexible tariffs standard in larger portfolios. [98]

## Scenario Dashboard To 2030 And 2050

The following scenarios use **60,000** as a conservative floor for 2025 MCS-certified installations and apply constant growth through 2030. They are planning cases, not predictions. The Warm Homes Plan's 450,000 aim has a broader policy scope, so the 49.6% comparison indicates scale rather than a like-for-like forecast.

| 2025-30 annual growth | 2030 annual MCS run-rate | Cumulative 2026-30 | Interpretation |
|---:|---:|---:|---|
| 15% | 120,681 | 465,224 | Organic growth; policy goal missed by a wide margin |
| 25% | 183,105 | 615,527 | Strong market expansion; installers and merchants scale steadily |
| 35% | 269,042 | 806,305 | Policy-led acceleration; skills and grid coordination become material |
| 50% | 455,625 | 1,186,875 | Approximate policy-fulfilment case; requires exceptional execution |

A reasonable base case is continued double-digit growth, with annual installations reaching roughly **120,000-185,000 by 2030** under 15%-25% growth. The upside case moves above 250,000. Reaching 450,000 requires coordinated success across grants, new-build standards, tariff reform, finance, consumer confidence, manufacturing and installer capacity. The downside case is not contraction; it is growth that remains too slow for carbon pathways.

Cooling should be planned separately. Current penetration of around 3% leaves substantial headroom, but the **5%-32% English household range by 2050** is too wide for a single equipment-demand forecast. Suppliers should monitor cooling-degree days, overheating assessments, regional enquiries, reversible-system share and summer grid constraints. [93] [17]

The most useful operating dashboard is:

1. MCS-certified installations and BUS redemptions, not factory sales alone.
2. Survey-to-order and order-to-install conversion rates.
3. Installed cost after grant and associated building work.
4. Metered seasonal performance factor and customer running cost.
5. Cooling enquiries and reversible-system share by region.
6. Qualified installer count, productivity, call-backs and complaints.
7. Low-GWP equipment share and F-gas-qualified service coverage.
8. Flexible-tariff, PV and storage attachment rates.

Companies should build capacity in geographic modules and trigger expansion only when conversion, installer productivity and post-install performance meet thresholds. This avoids overbuilding against a policy target while preserving upside exposure.

## Synthesis

England is not moving from boilers directly to one replacement technology. Four strategies will coexist, each with a different mechanism, scope, evidence base and risk profile.

| Strategy | Mechanism and scope | Main advantage | Main trade-off | Evidence and time horizon |
|---|---|---|---|---|
| Hydronic air-source heat pump | Replaces boiler and supplies radiators plus hot water | Best fit with the existing wet-heating base and GBP7,500 support | Retrofit disruption and tariff-sensitive operating cost | Fastest growth through 2030 |
| Reversible air-to-air heat pump | Direct space heating and cooling | Lower-cost dual service, especially without wet central heating | Usually needs a separate hot-water solution | Increasing role as cooling grows to 2050 |
| Passive-first cooling | Shading, ventilation, orientation and fabric control | Avoids energy use, refrigerant and peak demand | Cannot eliminate overheating in every existing building | Required design logic now; value rises with warming |
| Integrated smart-energy system | Heat pump plus controls, flexible tariff, PV or storage | Improves self-consumption, flexibility and delivered energy cost | Higher capital cost and complexity; some savings evidence is small-sample | Selective adoption through 2030, broader later |

The non-obvious tension is that heating decarbonisation and climate adaptation can pull the electricity system in different seasonal directions. Hydronic heat pumps add winter demand, while air conditioning adds summer peaks. Reversible units improve equipment utilisation by providing both services, but they can also encourage cooling that passive design might have avoided. The appropriate sequence is therefore reduce load, choose the right heat-pump architecture, use low-GWP refrigerant, add smart control, and then add generation or storage where the economics are verified.

A second tension lies between policy certainty and customer economics. New-build standards can make low-carbon heating normal even when payback is weak, but the retrofit market remains voluntary and cost-sensitive. The GBP7,500 grant solves part of the capital barrier, not the electricity-to-gas price ratio or disruption. This is why the new-build segment can grow predictably while owner-occupied gas replacements remain uneven.

The competitive divergence is equally important. Manufacturers win through efficient low-GWP products and installer support. Energy retailers win by combining tariffs, finance and installation. Local contractors win through property knowledge, trust and aftercare. Merchants win by making equipment, spares and training available. No player controls every constraint, so partnerships will outperform stand-alone equipment sales.

Overall, the installation trend in England is firmly upward. Heat pumps should grow faster than the wider HVAC market, reversible air-to-air systems should gain as heating and cooling converge, and conventional cooling should expand from a very low residential base. The most credible 2030 outcome is strong double-digit growth below the 450,000 policy aim, with an upside path if tariff reform, grants, new-build enforcement and installer productivity align. The winning strategy is not to sell the most equipment; it is to deliver reliable comfort at a modelled whole-system cost while keeping cooling loads, peak power and refrigerant risk under control.
