Do I Need an Energy Statement for Planning Permission in the UK?
If you’re submitting a planning application in the UK, there’s a strong chance you’ll be asked to provide an energy statement.
For many developers, this can feel unclear - when is it required, what does it include, and how detailed does it need to be?
This guide explains when energy statements are needed, what local authorities expect, and how to ensure your project meets current energy and planning requirements.
What is an energy statement?
An energy statement is a report submitted as part of a planning application that demonstrates how a development will meet energy efficiency and carbon reduction targets.
It typically outlines:
The building’s predicted energy performance
Carbon emissions and reduction strategies
Proposed renewable energy technologies (such as solar PV)
Compliance with local and national policy
The goal is to show how the development aligns with planning policy and contributes to the UK’s net zero targets.
When is an energy statement required?
Requirements vary depending on the local planning authority, but energy statements are commonly required for:
New residential developments
Commercial and mixed-use schemes
Larger refurbishments or conversions
Developments in areas with specific sustainability policies
Many councils - particularly in London and the South - have strict energy and carbon policies, often requiring:
A minimum percentage of on-site renewable energy
Carbon reduction targets beyond national regulations
Detailed modelling of energy performance
If your project falls into one of these categories, an energy statement is very likely to be required.
What needs to be included?
While formats vary, most energy statements include:
1. Energy demand reduction
How the building design reduces energy use through fabric performance, insulation, and efficiency measures.
2. Energy efficiency
Details of systems such as heating, cooling, lighting, and ventilation.
3. Renewable energy strategy
Proposals for technologies such as:
Battery storage
4. Carbon emissions calculations
Typically based on SAP or SBEM modelling, showing compliance with regulations and policy targets.
5. Policy compliance
A clear explanation of how the development meets local planning requirements.
How does this relate to Part L compliance?
An energy statement sits alongside Part L of the Building Regulations, but they are not the same thing.
Part L focuses on minimum legal standards for energy performance
Energy statements often go further, responding to local planning policies
In many cases, you will need both:
SAP or SBEM calculations for compliance
An energy statement for planning approval
Common challenges developers face
Some of the most common issues include:
Underestimating local authority requirements
Leaving energy strategy too late in the design process
Relying on standard solutions that don’t meet policy targets
Missing opportunities to integrate renewables effectively
Addressing energy requirements early can prevent delays and redesign later.
How Helix Energy UK supports planning applications
At Helix Energy, we work with developers, architects, and project teams to prepare clear, policy-compliant energy statements.
We support projects from early-stage design through to submission, including:
Energy modelling (SAP and SBEM)
Renewable energy strategy development
Planning documentation
Ongoing compliance support
Our focus is on delivering practical, buildable solutions that meet both planning requirements and project objectives.
In most cases, if you’re submitting a planning application for a new development in the UK, you will need an energy statement.
Understanding what’s required - and addressing it early - can make the planning process smoother and more predictable.
If you’re preparing a planning application and need support with an energy statement - contact us. Helix Energy can help guide your project through the process.
