Why is the Future Homes Standard necessary?
Climate change poses a serious threat, both in the UK and globally. Homes contribute significantly to the UK's carbon footprint.
Upgrading standards for new buildings is essential to successfully reduce greenhouse gas emissions and support the UK's legally mandated commitment of achieving net zero emissions by 2050.
The Future Homes Standard, embedded in updated Building Regulations, provides the government intervention needed to overcome resistance to change in construction practices and create a more sustainable future for housing in the UK.
What are the key requirements of the Future Homes Standard?
-
Fabric Efficiency
Improved insulation levels: Walls, floors, and roofs will require higher R-values.
Enhanced airtightness: Minimizing air leakage through gaps and cracks in the building envelope is crucial for reducing heat loss.
Thermal bridge reduction: Addressing weak points in the building envelope where heat can escape more easily.
-
Low Carbon Heating & Hot Water Systems
The FHS emphasises the use of low-carbon alternatives like air source heat pumps (ASHPs) or ground source heat pumps (GSHPs) for heating and hot water. Gas boilers will not be compliant.
-
Renewable Energy Readiness
While not mandatory, the FHS encourages incorporating features like pre-wiring or space allocation for installing solar panels in the future.
-
Ventilation
MEV and MVHR are encouraged. These systems provide energy efficient ventilation for new and existing homes without compromising the airtightness of the building's envelope.
-
EV Charging Infrastructure
New homes will need to have one charging point installed or the necessary cabling pre-installed to facilitate future installation.

What are the requirements for windows and doors?
The Future Homes Standard sets stricter window requirements for energy efficiency.
New builds need windows with a U-value of 1.2 W/m²K or lower. Norrsken's award-winning windows surpass this standard, achieving U-values as low as 0.64 W/m²K for effortless compliance.

What are the requirements for new homes?
Meeting the Future Homes Standard (FHS) involves a combination of design elements and technology advancements.
New homes must meet requirements for U-values and energy efficiency set out in Part L of the Building regulations. They must also meet or demonstrably work towards meeting the five criteria below.
Implications of the Future Homes Standard
-
What are the implications of the Future Homes Standard for the industry?
The initial capital costs of the changes to building standards are likely to be borne by developers.
Transitional costs are likely to fall on businesses and Local Authority building control who will need to train their employees to become familiar with the new standards. This includes employees such as contractors, architects, energy assessors and building control etc.
Over the medium-long term, development costs may become factored into land prices and therefore passed onto landowners.
-
How will the Future Homes Standard be assessed?
Developers will demonstrate compliance with the FHS through the Home Energy Model (HEM), an update to the Standard Assessment Procedure (SAP10) currently in use for modelling building energy consumption.
This software tool will be used to model the energy performance of a new home and ensure it meets the FHS requirements.
To more accurately calculate the energy use, allow the assessment of peak load and model smart technologies, HEM breaks the year into half-hourly chunks, rather than monthly under current SAP, allowing for much more dynamic energy modelling.
-
What is the cost of the Future Homes Standard?
While the FHS may involve higher initial costs in some cases (of advanced insulation materials, low carbon heating systems and the potential need for more rigorous design and greater expertise), the long-term benefits in terms of energy savings, reduced maintenance, and potential property value appreciation are expected to outweigh the initial investment.
Additionally, government initiatives aim to mitigate cost concerns by promoting industry preparedness and exploring potential financial support mechanisms.
-
Does the Future Homes Standard affect existing homes?
At present, the future homes standard only affects new buildings constructed in England after 2025.
However, retrofit of the country’s existing building stock is also necessary to reach the UK’s zero carbon commitments.

Future Homes Standard vs Passive House?
Both the Future Homes Standard and the Passive House (or Passivhaus) standard govern the way houses are designed and built, and both represent an uplift in stringency from the current UK Building Regulations. However, the scope, requirements and performance achieved by the two differ:
-
The Future Homes Standard
Sets minimum performance standards for new homes in the UK, focusing on achieving significant carbon emission reductions and improving overall energy efficiency.
The FHS represents a significant step towards improving the energy performance and sustainability of new homes in the UK, ensuring a minimum level of efficiency and carbon reduction of 75-80% compared to current regulations.
Suitable for developers and homeowners seeking a balance between achieving significant improvements in energy efficiency and carbon reduction, affordability, and practicality.
-
The Passive House Standard
A voluntary international building standard targeting drastically reduced heating and cooling needs, resulting in very energy-efficient buildings.
The Passive House Standard offers an even more ambitious approach to energy efficiency, achieving near-zero space heating needs and a reduction of more than 90% of space heating needs compared to typical new builds.
However, it requires greater commitment, expertise, and cost compared to the FHS. Ideal for those aiming for the highest level of energy efficiency and sustainability possible, with the understanding of potentially higher costs and complexity involved.

What is the goal of the Future Homes Standard?
The objectives of the policy are to deliver: Significant carbon savings, contributing to the UK’s net-zero goal by 2050.
High-quality homes that remain affordable, protecting occupants from excessive energy bills while offering a comfortable and healthy living environment;
Achieving "Zero-Carbon Ready" status: Homes built under the FHS will be designed and built with renewable or electric energy sources so that when the electricity grid becomes fully decarbonized, no further modifications will be necessary for the building to achieve zero carbon emissions. This means that gas boilers, including hybrid and hydrogen-ready versions, will not be compliant with this standard.
Cost-effective and achievable approaches to low-carbon heating systems. This ensures the construction industry can realistically adopt these clean energy approaches, considering their current skills, existing supply chains, and ability to deliver these solutions across various locations.
When will the the Future Homes Standard be enforced?
The Future Homes Standard will be fully implemented from 2025 onwards, with a transitional period from mid-2023 onwards that enforces certain areas of the regulations.
The roadmap to implementation is below:
1. Consultation and Development (2020-2024):
- The government conducted extensive consultations with various stakeholders like industry professionals, environmental groups, and consumer organisations to gather feedback and refine the standard's details.
- The Future Homes and Buildings Standards were formally consulted on in 2023 with further refinements based on feedback.
- Legislative enactment is expected in 2024 to officially introduce the FHS.
- Approved Document O has been updated to provide detailed guidance on complying with the FHS, similar to how Approved Document L sets out requirements for current regulations.
2. Transitional Period (2024-2025):
- Following the legislation, a transitional period is being considered, lasting 6 to 12 months (the details are still under discussion). This allows the industry time to adjust and prepare for the new regulations.
- During this period, new developments may be able to comply with either the existing Building Regulations or the FHS.
3. Full Implementation (2025 Onwards):
- From 2025 onwards, all new homes must comply with the Future Homes Standard. This means meeting the specified energy efficiency and carbon emission reduction targets.
- The Home Energy Model (HEM) will be the primary tool used to demonstrate compliance during the building design and planning stages.
How will the government support the Future Homes Standard’s implementation?
Skills development programs:
The government is investing in training initiatives to equip professionals with the skills needed to implement the FHS effectively.
Supply chain development:
Measures are being taken to encourage the development and availability of low-carbon technologies and materials required for FHS compliance.
What is the Future Homes Standard for England by 2025?
Launching in 2025, the Future Homes Standard (FHS) revolutionizes UK new builds.
FHS slashes carbon emissions by 75-80%, prioritizes low-carbon heating, and focuses on super-insulated, energy-efficient homes with energy-efficient windows and doors.
This ambitious standard requires industry innovation to create comfortable, sustainable homes for the future.
