Market Size Data
| Year | Installations | Market Value (£bn) | Average Installation Cost | BUS Grant Uptake |
|---|---|---|---|---|
| 2022 | 72,000 | 1.1 | £14,500 | 25,000 |
| 2023 | 130,000 | 1.9 | £13,500 | 65,000 |
| 2024 | 195,000 | 2.8 | £12,800 | 120,000 |
| 2025 | 250,000 | 3.8 | £12,000 | 175,000 |
Market value includes equipment, installation labour, ancillary components, and first-year servicing. Data from MCS, DESNZ, and industry sources.
The declining average installation cost reflects several factors: increasing competition among installers, maturing supply chains, growing manufacturing scale, and VAT zero-rating. As volume continues to increase, further cost reductions of 5-10% are expected by 2028.
Growth Drivers
Five key factors are driving market growth:
- The BUS grant at £7,500 — reducing out-of-pocket costs to competitive levels with boiler replacement
- Rising gas prices — improving the running cost comparison with heat pumps
- Clean Heat Market Mechanism — requiring boiler manufacturers to sell increasing proportions of heat pumps
- Future Homes Standard — mandating heat pumps in new builds
- Growing consumer awareness — word-of-mouth from satisfied owners driving demand

Supply Chain Developments
The UK heat pump supply chain has matured significantly, with major developments including dedicated heat pump distribution networks, expanded warehouse capacity, growing domestic component manufacturing, and improved lead times (now typically 1-2 weeks for popular models, down from 4-8 weeks in 2022-23).
UK Manufacturing
UK-based heat pump manufacturing is a growing policy priority. Current developments include Octopus Energy's partnership with Daikin for UK production in Bristol, Mitsubishi's expanded assembly operations, and government industrial strategy support for domestic manufacturing. UK production could eventually reduce costs by 10-15% through eliminated import logistics and tariff advantages.
European Comparison
The UK trails France, Italy, and Germany in absolute numbers but is growing faster than most European peers. Per capita, the UK lags Scandinavian countries where heat pump penetration exceeds 50%, but is comparable to other large European markets. Learning from European leaders, particularly on electricity pricing and installer training, could accelerate UK adoption. For comparison with gas-based systems, see our gas boiler comparison.
Investment Trends
Investment in the UK heat pump sector is accelerating across multiple dimensions: manufacturer capital expenditure on UK facilities and R&D, venture capital funding for heat pump technology startups, training investment from both government and private sector, and grid infrastructure investment to support electrification of heating. The total investment pipeline is estimated at £2-3 billion over the next five years.
Market Forecast 2027-2030
| Year | Projected Installations | Projected Market Value | Key Assumptions |
|---|---|---|---|
| 2026 | 300,000-350,000 | £4.5-5.5bn | CHMM takes effect, BUS continues |
| 2027 | 400,000-500,000 | £6.0-7.5bn | Electricity rebalancing begins |
| 2028 | 500,000-600,000 | £7.5-10.0bn | Target year for 600k/yr |
| 2030 | 600,000-700,000 | £9.0-12.0bn | Mass market adoption |
Projections based on current growth trajectory, policy commitments, and industry capacity development.
If combined with solar panel installations (increasingly sold as combined packages), the total renewable home energy market could exceed £15 billion by 2030. The BUS grant remains the most important policy lever for driving consumer demand.
