ESOS Phase 4: Go Beyond Compliance

With ESOS Phase 4 deadlines fast approaching, businesses must once again assess their energy use and submit compliant audit reports. But at Celtic Dynamics, we believe these audits shouldn’t just meet minimum requirements, they should deliver real operational insight.
Our approach to ESOS blends compliance with strategy. We carry out detailed on-site assessments to identify your highest areas of energy consumption, calculate usage in both kilowatt hours and cost, and provide clear, financially grounded recommendations for energy reduction. All of this is documented in a submission-ready report that satisfies Environment Agency requirements while also informing practical change.
Turning Audit Insight into Action
Many businesses complete their ESOS audits but struggle to implement the findings. That’s where our Action Plan Activation service comes in.
We work with internal stakeholders to develop implementation plans that align with your operational and budgetary needs. From coordinating technical contractors to tracking savings and integrating with your Net Zero or ISO frameworks, we manage the entire process, ensuring your audit turns into action, not just a file on a shelf.
This turnkey service is especially valuable for organisations facing internal resource limitations or seeking guaranteed delivery.
Energy Support for B Corps: Proof Over Promises
For certified and aspiring B Corps, energy performance plays a pivotal role in your B Impact Assessment (BIA) scores. Our tailored B Corp energy audit helps purpose-led businesses strengthen their environmental credentials by directly improving their B Impact Assessment scores.
We provide carbon footprinting for Scopes 1 and 2 (with Scope 3 as an option), evaluate your energy sources, and recommend improvements that support your sustainability goals. More than a diagnostic tool, this audit offers practical pathways to enhance your environmental impact and governance performance.
For B Corps looking to go further, we also deliver project management services to implement low-carbon upgrades, facilitate supply chain improvements, and foster staff engagement through behavioural change initiatives. The goal is to embed environmental action across operations, not just policy.

Smarter Energy Investment: Feasibility with Evidence
The pressure to transition to renewable and low-carbon technologies is growing, but where and how should businesses invest?
Each low carbon feasibility study we deliver evaluates the technical, environmental and financial case for clean energy technologies, from solar PV to battery storage. Reports include energy yield projections, carbon savings, capital and operational costs, and available funding options.
For projects pursuing BREEAM certification, we also provide compliant Low or Zero Carbon (LZC) studies aligned to ENE 01, ENE 04, and ENE 05.
These insights ensure that your clean energy investments deliver both sustainability and commercial return.
Carbon Footprinting That Supports Strategy
Carbon footprint reporting is the foundation of any credible sustainability strategy. At Celtic Dynamics, our carbon footprinting and GHG reporting services follow the GHG Protocol and support a wide range of regulatory, investor, and voluntary frameworks.
We provide market-based and location-based emissions analysis, use BEIS/DEFRA-approved emissions factors, and track performance over time. Whether you’re reporting under SECR, contributing to B Corp assessments, or developing a Net Zero strategy, our data-driven approach ensures your reporting is consistent, transparent, and ready for action.
