Building or renovating a home in the coming years? Here’s what the Future Homes Standard means for your project, and why the right windows and doors matter more than ever.
If you’re planning a new build or self-build project, the Future Homes Standard (FHS) represents one of the most significant changes to UK building regulations in decades. Coming fully into effect by December 2026, these new requirements will reshape how homes are designed, heated and constructed across England.
The good news? With the right guidance and quality products, meeting – even exceeding – these standards is entirely achievable. Let’s break down what you need to know.
What is the Future Homes Standard?
The Future Homes Standard is the government’s flagship policy for creating low-carbon, energy-efficient homes that support the UK’s commitment to net zero by 2050. New homes built under the FHS must produce 75–80% fewer carbon emissions compared to those built under previous 2013 regulations.
The goal is not to simply tick boxes, but to revolutionise the UK housing stock. New homes in the UK should be warmer, quieter, more comfortable to live in, generate less carbon – and be significantly cheaper to run.
Key requirements you should know
The FHS introduces several interconnected requirements that work together to deliver exceptional thermal performance:
Low-carbon heating is mandatory. New builds will no longer connect to the gas network. Instead, homes must incorporate low-carbon heating systems such as air source or ground source heat pumps. The Boiler Upgrade Scheme offers up to £7,500 to help offset installation costs.
A fabric-first approach is essential. Before considering heating systems, the building envelope itself must perform to higher standards than current new builds. This means enhanced – and continuous – wall, floor and roof insulation, improved airtightness, and high-performance windows and doors.
Windows carry real weight. Under Part L requirements, windows must achieve a U-value of 1.2 W/m²K or lower. While triple glazed windows aren’t mandatory, they’re expected to become increasingly popular as homeowners and builders recognise their superior thermal performance, noise reduction and long-term value.
Ventilation matters. Part F requirements ensure homes maintain healthy air quality without compromising energy efficiency. As airtightness standards tighten, mechanical ventilation systems—whether continuous extract (MEV) or heat recovery (MVHR)—are becoming standard practice
The timeline: when will the Future Homes Standard be implemented?
Understanding the implementation schedule helps you plan effectively:
- Spring 2026: Final FHS regulations published
- December 2026: Projects without existing planning permission must meet FHS requirements
- December 2027: Transition period ends; all new homes must fully comply
- From 2028: Every new housing development must include a low-carbon heating plan from the outset
If you’re in the early stages of your project, now is the time to ensure your specifications align with where regulations are heading.
What about renovation projects?
The FHS primarily targets new builds, not existing homes. However, if you’re planning extensions, loft conversions or major renovations, you’ll still need to meet current Part L U-value requirements – and choosing products that exceed those standards future-proofs your investment.
Replacement windows and thermal elements like walls and floors must meet fabric efficiency standards, making this an opportune moment to specify double and triple glazed doors that deliver lasting performance.
Managing costs wisely
Government assessments suggest construction costs may rise by 3–8% under the FHS. However, these upfront investments are offset by substantially lower running costs, increased property values and reduced maintenance requirements over time.
For self-builders, much of this cost can be minimised by:
- Planning early and integrating energy modelling from the design stage
- Choosing products that already exceed minimum requirements, avoiding costly redesigns later
- Working with suppliers who understand both regulations and practical delivery
Finding the right support
Navigating new regulations needn’t feel overwhelming. The key is working with knowledgeable partners who can guide you through both the technical requirements and the practical decisions that bring your vision to life.
When specifying windows and doors, look for suppliers with:
- Proven thermal performance (U-values below the 1.2 W/m²K threshold)
- Experience with low-energy and Passive House projects demonstrates technical proficiency
- End-to-end support from consultation through installation
- A track record of helping homeowners achieve compliance with confidence
Norrsken’s triple-glazed windows, for example, achieve U-values as low as 0.64 W/m²K, comfortably exceeding FHS requirements while delivering the comfort, quietness and aesthetic quality that make a house feel like home. You can see what customers say about their experience on Trustpilot.
Building with confidence
The Future Homes Standard isn’t just a regulatory hurdle; it’s an opportunity to build better. Homes that meet these standards well will be more comfortable, more economical to run, and more valuable in the years ahead.
With thoughtful planning and the right partners, you can navigate these changes with confidence and create a home that truly reaches its full potential.
