Cost Benefit of the Zerith Approach
Example 1: Commercial Real Estate
Client: A financial services organisation occupying a single floor within a landmark London office building. Client has minimal influence on the building HVAC systems, & only has control of their office environment in terms of time of occupation, space temperatures, lighting fit out and controls, solar blinds, and small power associated with their fit-out of the building
Traditional Consultancy Approach: An external consultant is appointed to conduct the ESOS audit, prepare the compliance report, and provide ESOS Lead Assessor sign-off. The process is largely outsourced, with limited client involvement and minimal long-term capability retained in-house.
The Zerith Approach: ESOS compliance is delivered by the client’s internal team using the ZECO AI platform, with Zerith providing structured pre-audit and post-audit guidance, quality assurance, and ESOS Lead Assessor certification. The process is faster, more transparent, and fully compliant—while building internal understanding of energy performance.
Cost Comparison
Projected cost reduction: Up to 50%
Estimated saving: Approximately £1,500 compared to traditional consultancy delivery
Audit Outcomes
Identified energy-saving opportunities: Equivalent to the traditional approach
Maintained audit quality through Zerith technical oversight and guidance
Return on Investment
Improved ROI due to significantly lower upfront compliance costs
Enhanced value from any post-audit energy efficiency measures implemented
A more knowledgeable and empowered internal team, capable of sustaining and improving energy performance over time
Net Result
Full ESOS compliance at lower cost, equal technical insight, and long-term organisational benefit—without reliance on expensive third-party consultancy.
Example 2: Manufacturing Client
Client: Manufacturing Client, with a very large single site with production areas, offices, staff welfare facilities, Warehousing & Distribution.
Traditional Consultancy Approach: An external consultant is appointed to conduct the ESOS audit, prepare the compliance report, and provide ESOS Lead Assessor sign-off. The process is largely outsourced, with limited client involvement and minimal long-term capability retained in-house.
The Zerith Approach: ESOS compliance is delivered through a client-led, structured energy assessment, in this case an Energy Treasure Hunt (could also be an Energy Audit, or Kaizen event), with Zerith providing hands-on technical support throughout the process. Zerith specialists actively support the on-site Treasure Hunt, ensuring energy-saving opportunities are identified quickly and accurately, in line with ESOS requirements.
Following the on-site activity, the client’s Energy Manager completes the ESOS audit and evidence pack using the ZECO AI platform, supported by Zerith’s structured technical guidance, quality assurance review, and ESOS Lead Assessor certification.
This approach creates a more engaging and effective compliance process. It leverages deep internal knowledge of production processes, operational constraints, and building performance; increases energy awareness across teams; delivers full regulatory compliance; and builds lasting internal capability to manage and improve energy performance well beyond the ESOS cycle.
Cost Comparison
Projected cost reduction: Up to 40%
Estimated saving: Approximately £3,000 to £4,000 compared to traditional consultancy delivery
Audit Outcomes
Identified energy-saving opportunities: Increased energy savings compared to the traditional approach due to enhanced team engagement, leveraging of knowledge of systems & processes, and internal engagement to implement identified recommendations.
Maintained audit quality through Zerith technical support, oversight and guidance
Return on Investment
Improved ROI due to significantly lower upfront compliance costs
Enhanced value from any post-audit energy efficiency measures implemented
A more knowledgeable and empowered internal team, capable of sustaining and improving energy performance over time
Net Result
Full ESOS compliance at lower cost, equal technical insight, and long-term organisational benefit—without reliance on expensive third-party consultancy.
Example 3: Manufacturing – Climate Change Agreement (CCA)
Example 2: Manufacturing – Climate Change Agreement (CCA)
Client: A manufacturing organisation operating energy‑intensive processes and participating in the UK Climate Change Agreement (CCA) scheme.
Traditional Consultancy Approach: CCA reporting is typically outsourced to a specialist consultant who collects site data, prepares the target unit calculations, completes the submission, and manages correspondence with the scheme administrator. The process is often opaque, repeated every reporting period, and reliant on ongoing consultancy spend.
The Zerith Approach: CCA compliance is delivered by the client’s internal energy and operations teams using the ZECO AI platform, with Zerith providing structured technical guidance, training, and validation throughout the reporting cycle.
Zerith supports site teams in correctly structuring energy and production data, validating target unit calculations, and completing the CCA submission accurately and efficiently. Final submissions are reviewed by Zerith consultants to provide quality assurance and confidence prior to submission.
Cost Comparison
Projected reduction in consultancy costs: up to 60%
Significant reduction in recurring reporting costs across multiple CCA cycles
Compliance Outcomes
Fully compliant CCA submission meeting scheme administrator requirements
Improved data accuracy and consistency across sites
Greater transparency and control over performance against CCA targets
Return on Investment
Lower ongoing compliance costs through internal delivery
Improved understanding of energy‑intensity drivers at the process and site level
Earlier identification of efficiency opportunities supporting target achievement
Reduced risk of underperformance or buy‑out payments
Net Result CCA compliance delivered at lower cost, with greater operational insight, reduced risk, and a more capable internal team—transforming CCA from a reporting obligation into a tool for continuous energy performance improvement.
Example 4: Streamlined Energy and Carbon Reporting (SECR)
Client
A UK-based organisation operating across multiple sites, required to comply with Streamlined Energy and Carbon Reporting (SECR) as part of its annual statutory reporting.
Traditional Consultancy Approach
SECR is often delivered by an external consultant who gathers energy and fuel data, applies emissions factors, prepares the disclosures, and provides narrative text for inclusion in the Directors’ Report. This process is repeated annually, with limited transparency and ongoing consultancy costs.
The Zerith Approach
SECR reporting is delivered by the client’s internal finance, sustainability, or energy teams using the ZECO AI platform, with Zerith providing structured guidance, validation, and quality assurance throughout the reporting cycle.
Zerith supports teams in centralising energy and fuel data across sites, applying the correct emissions factors, and generating SECR-compliant metrics and narrative outputs aligned with Companies House requirements. Final disclosures are reviewed by Zerith consultants to ensure accuracy, consistency, and audit readiness prior to submission.
Cost Comparison
Projected reduction in consultancy costs: Up to 50–70%
Significant savings achieved through repeatable, in-house delivery year on year
Compliance Outcomes
Fully compliant SECR disclosures integrated into statutory accounts
Improved data quality and consistency across reporting periods
Clear audit trail supporting financial and non-financial assurance
Return on Investment
Reduced annual reporting costs and dependency on third-party consultants
Better visibility of energy and carbon performance at the portfolio and site level
Stronger alignment between financial, energy, and Net Zero reporting
Increased internal capability to manage future reporting and regulatory change
Net Result
SECR compliance delivered accurately, efficiently, and at lower cost—while creating a repeatable reporting process that supports better decision-making and long-term sustainability objectives.

An energy compliance consultant helps organisations understand, manage, and meet mandatory and voluntary energy and carbon regulations—while turning compliance into a source of insight and value rather than a tick-box exercise.
At Zerith, energy compliance goes beyond report writing. We support organisations to:
Identify which schemes apply, such as ESOS, SECR, CCA, Heat Network Regulations, ISO standards, and others
Collect, validate, and structure energy and carbon data across sites and portfolios
Produce accurate, audit-ready submissions that meet regulatory requirements
Provide assurance, quality control, and accreditation sign-off where required
Translate compliance outputs into actionable energy and carbon reduction opportunities
Uniquely, Zerith offers both traditional consultancy delivery and our ZECO AI-enabled approach, empowering internal teams to manage compliance more efficiently while significantly reducing ongoing consultancy costs.
The result is clear compliance, better data, lower risk—and a stronger foundation for energy efficiency and Net Zero planning.
-
To become ESOS compliant, an organisation must measure total energy consumption, identify significant energy uses, and complete an approved energy assessment every four years, followed by submission to the Environment Agency.
In practice, ESOS compliance involves:
Confirming eligibility (based on size, turnover, and employee numbers)
Collecting and validating energy data across buildings, transport, and industrial processes
Identifying significant energy users
Completing ESOS-compliant energy audits or using ISO 50001 certification
Appointing an ESOS Lead Assessor
Submitting the required ESOS notification and evidence pack
At Zerith, we support ESOS compliance in two ways:
The Zerith approach: enabling your internal teams to self-deliver ESOS using our ZECO AI platform, with training, quality assurance, and Zerith being your Lead Assessor sign-off
Traditional consultancy delivery: where Zerith completes the audits, analysis, and reporting on your behalf
Both approaches ensure full compliance while creating long-term value—using ESOS as a foundation for energy efficiency improvements, cost reduction, and Net Zero planning, not just a regulatory obligation.
-
SECR does not have a standalone submission deadline. It must be included within your annual accounts and Directors’ Report, so the deadline aligns with your Companies House filing date.
Typical deadlines:
Private companies: within 9 months of the financial year end
Public companies: within 6 months of the financial year end
Example
If your organisation’s financial year ends on 31 December:
A private company must submit its accounts (including SECR disclosures) by 30 September the following year
A public company must submit by 30 June the following year
Because SECR is part of statutory reporting, missing the deadline can delay accounts approval and increase compliance risk.
At Zerith, we align SECR data collection and validation with your financial reporting cycle—using our ZECO AI platform or traditional consultancy delivery—to ensure submissions are accurate, timely, and audit-ready.
-
An ESOS Lead Assessor is a qualified professional approved to oversee and sign off an organisation’s ESOS compliance.
To qualify, an individual must:
Be a member of an approved ESOS professional body register (such as the Energy Institute, IEMA, CIBSE, or similar)
Hold relevant technical competence in energy management, auditing, or building/process performance
Have appropriate training and experience aligned with ESOS requirements
Be able to review, approve, and sign off ESOS audits and submissions to the Environment Agency
The Lead Assessor is responsible for ensuring that:
Energy audits meet ESOS regulations
Significant energy uses are correctly identified
Findings are robust, compliant, and evidence-based
At Zerith, all ESOS submissions are reviewed and signed off by approved, experienced ESOS Lead Assessors, whether you choose our ZECO AI-enabled self-delivery approach or our traditional consultancy-led ESOS service. This ensures full compliance, reduced risk, and maximum value from the ESOS process.
-
Item descriptMissing an energy or carbon compliance deadline can expose an organisation to regulatory scrutiny, reputational risk, and potential financial penalties, depending on the scheme. Regulators may issue enforcement notices, request additional evidence, or require corrective action within a defined timeframe.
In practice, our experience is that once organisations realise a deadline has been missed—or are formally notified—they should act quickly to appoint specialist support to resolve the issue.
At Zerith, we regularly support organisations in this situation. We:
Rapidly assess your compliance position
Prioritise the critical actions required to close gaps
Mobilise our consultants and ZECO AI platform to accelerate data collection and analysis
Deliver the required audits, reports, and submissions as quickly as possible
Provide assurance and sign-off to restore compliance with minimal disruption
Our focus is on speed, accuracy, and risk reduction, helping organisations move back into compliance in the shortest achievable timeframe while laying the groundwork to avoid future issues.ion
