Sustainability and energy efficiency are becoming increasingly important across the UK property sector, with new regulations continuing to shape both residential and commercial development projects. With extensive experience in commercial conveyancing, Ives & Co Solicitors advises clients on development land transactions, property acquisitions, leases, refinancing arrangements, and the regulatory considerations that can influence future property value and compliance.
One major change attracting attention across the property industry is the Future Homes Standard, expected to come into force in 2026 as part of wider updates to Part L Building Regulations. These changes are designed to improve energy efficiency and reduce carbon emissions in new homes and developments.
What Is the Future Homes Standard?
The Future Homes Standard is a government-led initiative aimed at ensuring that new homes built from 2026 produce significantly lower carbon emissions compared with current standards. The changes form part of broader Building Regulation updates under Part L, which focuses on:
Energy efficiency
Carbon reduction
Heating systems
Building fabric performance
Ventilation standards
The overall goal is to reduce reliance on fossil fuels and improve long-term environmental performance in new developments.
Why This Matters for Commercial Conveyancing
Although the Future Homes Standard focuses primarily on residential development, it has major implications for:
Commercial developers
Mixed-use developments
Land acquisitions
Investment property
Build-to-rent projects
Commercial-to-residential conversions
Property transactions increasingly involve due diligence around:
✔️ Planning compliance
✔️ Energy efficiency obligations
✔️ Development viability
✔️ Construction standards
✔️ Future retrofit costs
These issues can directly affect property values, financing, development timelines, and future resale potential.
Key Changes Expected Under Part L 2026
According to Savills, the Future Homes Standard is expected to require homes to produce around 75–80% fewer operational carbon emissions compared with homes built under previous regulations. Expected features include:
Greater insulation standards
Improved airtightness
Low-carbon heating systems
Reduced reliance on gas boilers
Enhanced ventilation requirements
More efficient building fabric design
Developers may increasingly need to consider:
Air source heat pumps
Solar integration
Mechanical ventilation systems
Enhanced glazing systems
Renewable energy infrastructure
How the Regulations Could Affect Property Transactions
As sustainability regulations become stricter, buyers, lenders, investors, and tenants are paying closer attention to energy performance and long-term compliance risks. This may affect:
Property Valuations: Buildings requiring significant upgrades in the future may become less attractive to buyers or investors.
Development Costs: Higher construction standards may increase upfront development costs, although they may improve long-term efficiency and marketability.
Lending and Financing: Lenders are increasingly reviewing ESG considerations and energy efficiency standards when assessing development finance and commercial lending.
Lease Negotiations: Commercial leases are evolving to include more “green lease” provisions relating to energy efficiency obligations and environmental performance targets.
Planning and Development Considerations
Developers and landowners should also be aware that local authorities may adopt additional sustainability expectations alongside national regulations. This means planning applications may increasingly involve:
Environmental assessments
Sustainability statements
Carbon reduction strategies
Biodiversity considerations
Renewable energy integration
Early legal and planning advice can help identify potential risks before contracts are exchanged or developments commence.
Existing Commercial Buildings and Retrofit Pressure
While the Future Homes Standard mainly applies to new homes, it forms part of a wider shift toward improved building performance across the UK property market.
Commercial property owners are already facing:
EPC compliance pressure
Minimum Energy Efficiency Standards (MEES)
Tenant sustainability expectations
Potential retrofit obligations
Rising operational energy costs
This means energy efficiency is no longer simply a “future consideration” — it is increasingly influencing present-day property transactions and investment decisions.
Common Risks for Developers and Investors
Some of the most common issues arising in development transactions now include:
Underestimating future compliance costs
Purchasing land without assessing development viability under updated regulations
Delays caused by planning and environmental requirements
Insufficient due diligence around infrastructure requirements
Financing complications linked to sustainability targets
These risks can impact project profitability and transaction timelines significantly.
Frequently Asked Questions
Does the Future Homes Standard apply to commercial buildings? The primary focus is residential development, but the wider shift toward sustainability standards is also influencing commercial property regulation and investment expectations.
Will gas boilers still be allowed? The direction of travel strongly favours low-carbon heating systems, with reduced reliance on traditional gas boilers in new developments.
Could these regulations increase development costs? Potentially yes, particularly in the short term, due to higher construction and compliance requirements.
Why does this matter in conveyancing? Commercial conveyancing increasingly involves reviewing planning, environmental, and compliance risks that may affect future use, financing, or value of the property.
Final Thoughts
The Future Homes Standard represents a major shift in how developments will be designed, constructed, and assessed in the coming years. For developers, investors, landlords, and commercial property buyers, energy efficiency and sustainability considerations are becoming central to property transactions rather than secondary issues.
Understanding how evolving regulations may affect development potential, financing, compliance obligations, and long-term property value will be increasingly important as the 2026 implementation date approaches.
