As the UK pushes forward with its optimistic commitment to reach net zero carbon emissions by 2050, one of the most significant challenges in achieving net zero lies in heat in buildings.
The Heat and Buildings Strategy, published by the UK Government, is a roadmap to prevent the harmful effects of climate change, tackle fuel poverty and seek energy security.
In this blog, we will break down the Heat and Buildings Strategy in its key objectives, the technologies and energy efficiency involved, and what it means for commercial and domestic properties.
Why Heat in Buildings Matters
Heating buildings accounted for nearly a quarter of the UK’s total greenhouse gas emissions. Most of this comes from burning fossil fuels predominantly in the form of natural gas for space and water heating.
To meet climate targets, the UK must transition to low-carbon heating systems, improve energy efficiency, and support innovation for new technologies and energy sources such as heat networks.
The Heat and Buildings Strategy - A Low-Carbon Built Environment
The Heat and Buildings Strategy sets out its vision for a simple, affordable, and fair transition to low-carbon heating. The heat and buildings strategy aims to:
- Reduce emissions from homes, commercial, industrial, and public buildings.
- Support up to 240,000 skilled green jobs by 2035.
- Tackle fuel poverty and improve energy affordability.
- Boost UK manufacturing of clean heating technologies.
This transition is not just about environmental benefits, it’s also about economic opportunity, energy security and reducing fuel poverty, and healthier living environments.
Key Pillars of the Heat and Buildings Strategy
1. Improving Energy Efficiency
Before switching to low-carbon heating, buildings must be made more energy-efficient. Therefore the strategy supports:
- Upgrading insulation to reduce poor energy efficiency in walls, roofs, and floors.
- Installing double or triple glazing and draught-proofing amongst other energy efficiency measures.
- Smart energy management systems to reduce waste, reduce carbon emissions and improve energy performance.
The government continues to fund schemes like the Home Upgrade Grant and Social Housing Decarbonisation Fund to support these improvements, especially for low-income households.
2. Accelerating Heat Pump Deployment
Heat pumps are central to the strategy within the heat in buildings strategy. These devices extract heat from the air or ground and are three to four times more efficient than traditional boilers.
The government aims to:
- Install 600,000 heat pumps per year by 2028.
- Support households through the Boiler Upgrade Scheme, offering grants of up to £7,500.
- Encourage UK manufacturing to scale up production and reduce costs.

3. Decarbonising the Gas Grid
While heat pumps are ideal for many homes, and have potential for commercial business, the difficult buildings can often be hampered by technical, economical and practical reasons. Therefore these areas may benefit from low-carbon hydrogen or district heating networks (heat networks).
The strategy includes:
- Hydrogen trials in selected areas to test its viability for home heating.
- Investment in the role of heat networks within the energy system, which deliver hot water from a central source to multiple buildings.
These alternatives will be crucial for buildings where heat pumps are not practical for low carbon heating.
4. Phasing Out Fossil Fuel Heating
To drive the transition, the government plans to:
- End the installation of new gas boilers by 2035.
- Ban fossil fuel heating in new homes from 2025.
- Introduce minimum energy efficiency standards for rented properties.
These measures will ensure that new and existing buildings are future-proofed for a low-carbon future and climate change targets.
5. Supporting Consumers and Industry
The strategy recognises that change must be affordable and accessible. It includes:
- Financial incentives for homeowners and landlords.
- Training programmes to upskill workers from fossil fuels to green technologies supporting long term climate change.
- Public awareness campaigns to inform and engage consumers around heat in buildings, energy efficiency and low carbon heating technologies.
The government also plans to work closely with industry to ensure supply chains are ready and costs of lower carbon heating technologies come down over time.
What This Means for You
For Homeowners
If you own a home, you may be eligible for grants to improve insulation or install a heat pump. Over time, it is likely that consumer will benefit from:
- Lower energy bills due to improved energy efficiency.
- Increased property value from green upgrades.
- A shift away from fossil fuel heating such as gas boilers to low carbon heating like electric or hybrid systems.
For Landlords
Landlords will need to meet minimum energy efficiency standards and may be required to upgrade heating systems to improve overall energy performance. Financial support is available, but planning ahead may be essential to avoid future penalties.
For Businesses
Commercial buildings are also in scope of the heat in buildings strategy. Businesses can benefit from:
- Reduced operating costs through energy efficiency.
- Opportunities to lead in sustainable building design and reduce their estates greenhouse gas emissions.
For the Workforce
The transition will create thousands of jobs in:
- Heat pump installation and maintenance. From air source heat pumps to more complex ground source heat pumps.
- Insulation and retrofit services.
- Green construction and engineering.
Training and apprenticeships will be key to filling these roles and ensuring a just transition.
Challenges Ahead
While the strategy is ambitious, it faces several hurdles:
- Upfront costs for homeowners and businesses.
- Public awareness and trust in new technologies versus the gas for heat that the UK is used to.
- Supply chain readiness and skilled labour shortages for decarbonisation of heating systems.
To address these, the government must maintain strong policy signals, invest in training, and ensure that support reaches those who need it most.
Conclusion - Looking Forward
The Heat and Buildings Strategy is a cornerstone of the UK’s net zero journey. It offers a direction for the 2020s and beyond, with a focus on energy efficiency and low carbon technologies. By improving energy efficiency, embracing clean heat, and supporting innovation, the UK can reduce emissions, lower bills, and build a greener future.
In Summary:
- The strategy targets net zero emissions from buildings by 2050.
- It promotes energy efficiency, heat pumps, hydrogen, and heat networks.
- Financial support and job creation are central to the plan.
Whether you're planning a home upgrade or shaping corporate sustainability goals, understanding this strategy is essential.
