THE NEW FUTURE HOMES STANDARD – PARTS L & F
“…a fundamental evolution in construction practice…”
On 24th March 2026 the Ministry of Housing, Communities and Local Government published the Future Homes Standard.
SOCOTEC’s Head of Technical Joshua Davies explains the new guidance….
Overview of the New Standards
The Building Regulations etc. (Amendment) (England) Regulations 2026 represent a significant milestone in the UK's commitment to sustainable construction. These regulations implement the Future Homes and Buildings Standards, fundamentally transforming how we design and construct new residential and non-domestic buildings in England.
Key Implementation Dates
The regulations come into force on 24 March 2027 for standard building work, with specific provisions for higher-risk buildings taking effect on 24 September 2027. Transitional arrangements apply to projects where building notices, initial notices, or full plans applications were submitted before these dates, provided work commences within the specified timeframes.
Principal Technical Changes
Enhanced Energy Performance Requirements:
The amendments to the Building Regulations 2010 introduce several critical requirements:
- New Functional Requirement L3: The regulations create a new functional requirement (L3) for the provision of on-site renewable electricity generation systems for all new dwellings and buildings containing dwellings. This requirement forms part of broader amendments to Part L that ensure new buildings are constructed with low carbon space heating and hot water systems alongside high levels of energy efficiency. Together, these provisions represent a comprehensive approach to reducing carbon emissions in new construction.
- Revised Part L Objectives: The regulations now amend Part L of Schedule 1 to reflect dual aims—reducing greenhouse gas emissions whilst conserving energy—reflecting the integrated approach required for achieving net-zero targets.
- Expanded Fixed Building Services Definition: The scope now includes lifts, escalators, and moving footways in new non-domestic buildings, ensuring comprehensive energy efficiency across all building systems.

Updated Guidance Documentation
Three key approved documents provide detailed technical guidance:
Approved Document L (Energy and Greenhouse Gas Emissions)
Available in two volumes covering dwellings and non-domestic buildings respectively, the updated guidance addresses:
- Compliance routes for buildings connected to heat networks
- Heat loss limitations for low carbon heating systems
- Minimum efficiency standards for building services and heat pump controls
- Installation requirements for on-site electricity storage systems
- Enhanced commissioning procedures, emphasizing adherence to manufacturers' specifications for heat pump installations
- Guidance on fixing operational and maintenance information to heat pumps
- Insulation requirements for building heat distribution systems
Approved Document F (Ventilation)
The revised guidance for dwellings includes strengthened requirements for mechanical ventilation commissioning and installation standards, ensuring optimal indoor air quality alongside improved energy performance. The guidance emphasizes the role of competent persons schemes when installing mechanical ventilation systems.

Implications for Project Delivery :
Home User Guide Requirements
New regulation 40C mandates the provision of comprehensive information to homeowners of new dwellings in appropriate formats. This ensures end-users understand their building's systems and can operate them efficiently, bridging the performance gap between design intent and operational reality.
Real-World Performance Focus
The guidance places significant emphasis on proper commissioning of fixed building services in both new and existing homes, recognizing that theoretical energy performance must translate into measurable operational efficiency.
Quality Assurance Mechanisms
The regulations provide clear routes for certifying fixed building services installations through competent persons schemes, with defined enforcement options where work fails to meet required standards.
Strategic Considerations
These standards ensure that new homes and non-domestic buildings are constructed with low carbon heating and high levels of energy efficiency. Crucially, buildings meeting these standards will not require future retrofitting to achieve zero carbon operation as the electricity grid continues to decarbonize.
For construction professionals, early engagement with these requirements is essential. The technical specifications demand careful coordination across design disciplines, particularly regarding:
- Integration of renewable electricity generation systems
- Selection and specification of low carbon heating technologies
- Enhanced thermal performance standards
- Comprehensive building services commissioning protocols
Moving Forward
The Future Homes and Buildings Standards represent not merely regulatory compliance but a fundamental evolution in construction practice. Success requires collaborative effort across the entire project delivery chain, from initial design through to handover and beyond.
‘SOCOTEC remains committed to supporting clients through this transition, making such determinations for projects to achieve regulatory compliance in the new energy-efficient building landscape.’
