These updates come with a host of new rules, but what do they mean for you in practical terms? Let’s break it down.
What are the key requirements?
The primary goal of the FHS is simple: cut carbon emissions from new homes by 75-80% compared to 2013 standards. This will be achieved through several key updates, including:
- No fossil fuel boilers: From 2028, gas and oil boilers will no longer be allowed in most new builds. Instead, low-carbon alternatives, like air source heat pumps (ASHPs) and ground source heat pumps, will dominate. These systems harness renewable energy from the air or the ground to heat homes more sustainably.
- On-site renewable energy: Most new homes must now include solar panels or similar renewable technology. A typical home will need solar panels covering about 40% of the ground-floor area to meet the new standards. This will help reduce reliance on grid electricity, lowering both costs and emissions.
- Improved insulation and airtightness: Homes will need better insulation and airtightness, meaning fewer drafts and more efficient heating. Triple glazing is now becoming the norm, further improving the energy efficiency of your home.
- Zero-carbon ready homes: The aim is to build homes that can naturally evolve with the grid. As the UK’s electricity grid decarbonises, these homes will automatically become zero-carbon, meaning no additional retrofitting will be necessary.
How will the new standards impact the construction timeline?
The rollout of the Future Homes and Buildings Standards will be gradual to allow the industry to adapt:
- March 2026: The final regulations will be published, setting the stage for full implementation.
- March 2027: New planning applications must comply with the new standards.
- March 2028: The transition period ends. Any new homes starting after this date must meet the full FHS, even if their planning permission was granted earlier.
This extended timeline offers the construction industry some breathing room to get prepared for the upcoming changes.
What are the new compliance tools?
To ensure homes meet the new energy standards, the government has introduced two important tools:
- Home Energy Model (HEM): The HEM will replace the old SAP (Standard Assessment Procedure). It is designed to more accurately reflect the performance of modern heating systems, like heat pumps, and other smart technologies.
- Plug-in solar: Soon, you’ll be able to use plug-in solar panels, which are particularly useful for flats with limited roof space. These small, portable solar panels will help meet the new renewable energy requirements.
What does this mean for you?
As a homeowner or developer, these changes represent both challenges and opportunities. By incorporating low-carbon heating systems and renewable energy sources, you’ll future-proof your home, saving on energy bills and potentially increasing its value. The improved building standards will not only help reduce emissions but also create more comfortable, energy-efficient spaces to live in.
The Future Homes and Buildings Standards offer a blueprint for a more sustainable future. Though the changes will require investment upfront, the long-term benefits should be well worth it.
