The Future Homes Standard 2025 is set to revolutionise the way new homes are built in the UK, with a strong focus on efficiency, sustainability, and reducing carbon emissions. Designed to help the country meet its net-zero targets, the new regulations will significantly impact insulation, heating systems, and glazing requirements, making high-performance windows and doors more important than ever.
But what exactly does the Future Homes Standard mean for homeowners, developers, and the construction industry? In this guide, we’ll break down the key changes, how they affect windows and glazing, and what you need to do to make sure your home or project is compliant.
What is the Future Homes Standard 2025?
The Future Homes Standard 2025 is a set of government regulations designed to improve the energy efficiency of new homes in the UK. Not in effect, it aims to make sure that all new-build homes are future-proofed with low-carbon heating systems and insulation.
Why was the Future Homes Standard introduced?
The UK government introduced the Future Homes Standard in response to growing concerns over climate change and energy efficiency in housing. The residential sector accounts for a large portion of the UK’s carbon emissions, primarily due to outdated heating systems and poor insulation in many homes.
With rising energy costs and increasing demand for sustainable living solutions, the standard aims to reduce energy consumption in new builds from the outset, eliminating the need for costly retrofits in the future.
Key objectives of the standard
The Future Homes Standard has several objectives, all aimed at creating sustainable homes that align with the UK’s climate commitments. These include:
- Reducing carbon emissions – New homes will need to produce at least 75-80% fewer emissions than those built under previous regulations.
- Eliminating reliance on fossil fuel heating – Traditional gas boilers will be phased out, with low-carbon alternatives such as heat pumps and district heating systems becoming the norm.
- Insulation and airtightness – New homes will be required to have better insulation, improved airtightness, and ventilation to lessen heat loss.
- Encouraging renewable energy solutions – Builders and homeowners will be incentivised to install solar panels, triple glazing, and materials to further enhance a home’s performance
How will the Future Homes Standard impact new builds?
Stricter energy efficiency targets
The Future Homes Standard 2025 aims to significantly reduce carbon emissions from new homes, setting ambitious energy efficiency targets that will shape the future of UK housing. Under the new regulations, homes will need to produce 75–80% less carbon than those built under current building regulations.
This means that traditional gas boilers will be phased out in favour of low-carbon heating solutions such as heat pumps and district heating systems.
Changes to insulation and heat loss requirements
To meet the new targets, higher insulation standards will be introduced, focusing on reducing heat loss through walls, floors, roofs, and glazing. Homes will be required to meet lower U-values, meaning they must achieve better thermal performance across all building materials.
This includes high-performance glass with improved solar gain control and airtightness, helping to minimise drafts and temperature fluctuations. Developers will need to incorporate better-insulated windows and doors, as well as triple glazing in some cases, to comply with the Future Homes Standard.
What does this mean for windows and glazing?
Enhanced U-value requirements for glazing
One of the most significant changes under the Future Homes Standard 2025 is the tightening of U-value requirements for windows and glazing. The U-value measures how well a window prevents heat loss, with lower values indicating better insulation.
The new regulations are expected to mandate U-values below 1.2 W/m²K, making double glazing with high-performance coatings, and in some cases even triple glazing, essential for compliance. This shift aims to reduce heat loss in homes.
The importance of solar gain and ventilation
While improved insulation is crucial, balancing solar gain and ventilation is just as important to maintain a comfortable indoor environment. Solar gain refers to the heat energy from the sun that passes through glazing, helping to naturally warm a home and reduce reliance on artificial heating in colder months.
However, excessive solar gain can lead to overheating, particularly in south-facing rooms with large glass areas. The Future Homes Standard encourages intelligent glazing choices, such as solar control glass and well-positioned rooflights and windows, to allow natural warmth in winter while preventing overheating in summer.

How will the standard affect homeowners and developers?
Implications for property developers and construction firms
The Future Homes Standard 2025 introduces stricter energy efficiency regulations that will require property developers and construction firms to adopt new materials, technologies, and building methods.
With a greater emphasis on low-carbon heating systems and high-performance glazing, developers will need to make sure all new homes meet the reduced U-value requirements. This shift will likely drive changes in procurement, with an added demand for efficient windows, triple glazing, and solar control glass to meet compliance standards.
While the new regulations may lead to higher initial construction costs, they will also contribute to long-term savings for homeowners by reducing energy consumption. Developers who embrace these changes early can gain an edge by marketing homes as future-proof and eco-friendly to buyers who are prioritising sustainability.
Potential costs and benefits for homeowners
For homeowners, the Future Homes Standard 2025 presents both opportunities and challenges.
On one hand, those purchasing newly built homes can expect superior insulation, lower energy bills, and a reduced carbon footprint, making their properties more comfortable and cost-effective to run.
Homeowners of existing properties are not required to meet these new standards, but they may face increased pressure to retrofit their homes with better insulation, windows, and sustainable heating systems if they want to keep up with evolving energy standards. While upgrading to glazing or installing triple glazing may involve an upfront investment, the long-term benefits include improved thermal efficiency, lower heating costs, and a potential increase in property value.
Key dates and next steps
When does the Future Homes Standard come into effect?
The Future Homes Standard takes full effect in 2025, meaning that all new homes built from this year onward must comply with stricter energy regulations. However, the transition is already underway. The 2021 Part L Building Regulations update introduced interim measures to prepare the industry for the upcoming changes, including improved insulation standards and lower carbon emission targets.
Developers and homeowners planning projects in the next few years should be aware that any new builds started before 2025 may still need to meet these evolving standards, especially as further government guidance is expected before the final rollout.
What homeowners and developers should do now
For developers and construction firms, this means incorporating low-carbon heating solutions, upgrading insulation, and ensuring glazing meets U-value requirements to lessen heat loss.
Homeowners looking to improve their existing properties should consider upgrading to high-performing windows and skylights, such as triple glazing or low-emissivity glass, to boost energy efficiency and potentially future-proof their homes against further regulatory changes.
