Energy Assessments & Sustainability Reports
Energy Statements
Introduction
Most planning authorities require developers to submit an Energy Statement as part of their application process.
Depending on the location, this document may be referred to by different names, such as:
A Sustainable Construction Checklist
A Sustainability Statement
An Energy & Sustainability Statement
Regardless of terminology, these reports are intended to demonstrate how a proposed development will comply with local energy and sustainability policies, including targets for energy demand, carbon emissions, or the integration of renewable technologies.
Why Choose Us for Your Energy Statement?
We have extensive experience delivering assessments for thousands of construction projects across numerous UK authorities, which allows us to navigate local planning policies and requirements with confidence.
We understand the importance of accuracy and efficiency to secure successful planning consent for your scheme.
It is also vital to provide tailored statements and reporting; our documents are designed not only to satisfy planning criteria but also to assist design and construction teams throughout the building process.
The Value of Energy Statements
An Energy Statement should serve as a precise working document, supporting informed decision-making, cost analysis, and risk mitigation. A reputable consultant will take time to understand your objectives, explore various options, and conduct early-stage energy assessments and modelling.
SAP or SBEM Calculations form the foundation of most studies and are required for compliance with building regulations. We collaborate proactively with your design team to produce consistent results and submit documentation to building control when appropriate.
Typically, an Energy Statement should:
Present baseline CO2 emissions and energy costs for standard scenarios
Demonstrate enhancements to fabric efficiency beyond regulatory standards
Outline improvements to HVAC and lighting efficiency above mandated levels
Provide evidence of CO2 reduction through renewable technology
Include a feasibility assessment for renewable technologies
Document how the scheme aligns with local energy plans and policies
Address the use of heat networks within the development
Calculate compliance with the zero-carbon requirements applicable in London
Air Permeability Testing
Additional unique or local planning policies may need to be addressed, depending on council requirements.
Build Energy undertakes a thorough review of project needs, engages with relevant planning departments if necessary, and assesses local policy before making recommendations.
In some instances, an energy statement may be required as part of a Design and Access Statement, or alongside a broader Sustainability Statement.
For expert guidance, refer to our blog articles: What is an energy statement? and the London Plan.

Sustainability Statements
Introduction
A Sustainability Statement is an essential component of any planning application.
When crafted effectively, it can facilitate a smooth approval process.
This report aims to show how the developer will meet local objectives—ranging from CO2 reduction and renewable energy targets to broader environmental concerns. These goals may be achieved by improving building fabric, using efficient systems, adopting renewable technologies, and considering other on-site environmental factors.
It’s worth noting that the name and scope of these reports can vary depending on location. Some authorities may ask for an ‘Energy Statement,’ which tends to focus on narrower issues. Others might require a ‘Sustainable Design and Construction Checklist’ aimed at meeting wider or more specific local demands. There are also other variations to keep in mind.
Typically, the Sustainability Statement is prepared during the pre-planning stage and submitted with the final application. Planning policies differ widely; for example, some areas follow ‘London Plan’ guidelines while others set their own renewable energy standards.
What is a Sustainability Statement?
This is a report showing how your project will address core sustainability policies as determined by your local authority. To find out which rules apply, you can:
View your local authority’s policy documents online
Request pre-planning advice or arrange a ‘pre-app’ meeting
Contact your sustainability officer, if available
If information is hard to access—or we don’t already know your local requirements—we’re happy to contact your planners to ensure their expectations are met. This helps you understand both costs and timelines.
A sustainability statement usually covers every aspect of the development that can help achieve high standards in sustainable design.
Energy Strategy
The energy strategy is often the most important section of any statement. It explains how your project will satisfy renewable technology requirements or CO2 targets.
For instance, many authorities (especially London Boroughs) require consideration of decentralised energy networks, such as Combined Heat and Power (CHP) systems. Applicants need to demonstrate how their projects will connect to existing infrastructure, or provide new supply.
Recent policy changes mean developers in London must now deliver Zero Carbon Homes on major developments.
We typically use SAP Calculations to demonstrate carbon emissions for residential schemes, and SBEM calculations for non-domestic projects.

Sustainability Statements – Tailored To Fit
It’s crucial to commission a report tailored specifically to your planning authority’s requirements.
Generic reports (often no more than glossy brochures) offer little value to design teams—they risk outright refusal and give clients no real benefit in delivering their scheme.
Depending on local guidance, you may also need to address water efficiency, flood risk or surface water management.
On larger projects, measures to minimise construction and demolition waste should be included. This might involve providing recycling facilities, reusing site waste, and choosing low-impact materials. Ecology reporting can help mitigate impacts on biodiversity.
We also examine strategies for maximizing natural light in buildings.
Buildings should be designed for adaptability. Responding to changing lifestyles and needs is increasingly important, as is considering whole life costing throughout the design process.
