SERVICES | ESOS compliance

ESOS compliance

The Energy Savings Opportunity Scheme (ESOS) is a mandatory energy assessment scheme for qualifying UK organisations. With the Phase 4 qualification date approaching on 31 December 2026 and the compliance deadline on 5 December 2027, now is the time to understand your obligations and prepare.

ESOS Phase 4 compliance support that delivers more than a tick-box exercise

Your trusted ESOS advisor

JRP helps organisations navigate ESOS compliance, from energy data collection and audits through to reporting and identifying practical opportunities to reduce energy consumption and costs.

Our experienced team of ESOS Lead Assessors combines regulatory expertise, sector knowledge and purpose-built tools to make compliance straightforward — while helping you get meaningful value from your assessment.

Prepare for ESOS Phase 4, meet your compliance obligations and uncover opportunities to improve energy performance.

ESOS requires qualifying organisations to assess their energy consumption across buildings, industrial processes and transport, identifying opportunities to improve energy efficiency.

The main dates for Phase 4 are:

  • Qualification date: 31 December 2026
  • Compliance deadline: 5 December 2027

Organisations must assess whether they meet the qualification criteria on the qualification date. Generally, this includes UK undertakings with 250 or more employees, or those with an annual turnover exceeding £44 million and an annual balance sheet total exceeding £38 million. Specific rules apply to corporate groups.

Phase 4 also introduces updated reporting requirements, including additional information on energy savings achieved and explanations where previous Action Plan commitments have not been met. Display Energy Certificates and Green Deal Assessments can no longer be used as alternative compliance routes.

Understanding your obligations early can help you plan the assessment, organise your data and avoid unnecessary pressure as the deadline approaches.

To get the most out of ESOS, to avoid excess costs and to ensure compliance, now is a good time to start planning for Phase 4. If you would like our help, here are four good reasons to talk to us.

Appointing us as your lead assessor will give you:

  1. Guaranteed compliance by the due date – or your money back! (subject to full and correct provision of company information)
  2. A free ESOS Organiser to help you manage the opportunities identified.
  3. A free user licence for Project Activator, our dynamic, user-friendly, web-based reporting tool to organise and track progress of improvement projects. (For qualifying organisations only. To find out if your organisation qualifies, please get in touch.)
  4. Sector expertise – your audit will be carried out by someone with expertise in your sector which means a more meaningful process from which you will get more value

Organisations that fail to meet their ESOS obligations may face enforcement action and financial penalties from the relevant regulator. They may also be required to take corrective action to achieve compliance.

The precise consequences depend on the nature of the breach and the applicable enforcement provisions.

Preparing early can help reduce the risk of missed deadlines, incomplete records and avoidable errors. It also gives your organisation more time to address data gaps and plan the work required.

We take a practical, data-led approach to ESOS, helping you understand your energy use, meet the scheme’s requirements and identify improvements that make a measurable difference.

ESOS energy audits and assessments

Our experienced energy consultants assess energy consumption across your organisation, helping identify significant energy uses, inefficiencies and opportunities to improve performance.

We tailor our approach to your operations and sector, ensuring the assessment provides relevant, actionable recommendations rather than a generic list of measures.

ESOS Lead Assessor services

Our accredited ESOS Lead Assessors guide you through the compliance process, helping you understand the requirements, coordinate the assessment and complete the necessary reporting.

We’ll work with your team to establish what information is needed, identify potential gaps and keep the process moving towards the compliance deadline.

Energy data collection and management

Accurate, accessible energy data is essential for a successful ESOS assessment. We help organisations bring together the information needed to understand consumption across sites, buildings, processes and transport.

Our purpose-built ESOS Organiser tool helps structure and manage compliance data, analysis and supporting evidence, making information easier to access and review.

Action Plans and progress reporting

ESOS is increasingly focused on demonstrating progress, not simply identifying opportunities.

We can help you understand your previous Action Plan commitments, review progress against measures and identify the information needed to support reporting obligations.

Turning recommendations into action

The real value of an ESOS assessment comes from understanding which opportunities are worth pursuing and how to deliver them.

We help organisations evaluate potential energy and cost savings, prioritise improvement projects and build a practical plan for implementation.

Where appropriate, our Project Activator tool can help you organise and track energy-saving projects, monitor progress and report outcomes in a format that supports better decision-making.

Our team combines ESOS Lead Assessor expertise with wider experience in energy management, audits and resource efficiency.

A practical, sector-specific approach

JRP have been instrumental in helping us to reduce our energy consumption and costs during a challenging period of organisational change and growth. Professional, reliable and easy to work with.

Steven Buchan, Estates Manager | Circle Health

Working with JRP Solutions transformed our energy management journey. Their expertise and tailored support for ISO 50001 and a behavioural change programme brought real clarity and momentum. We now have a robust framework and engaged team driving down energy use. Thank you to the JRP team for their expertise, commitment, and support throughout.

Ian Goldsworthy, Energy and Carbon Reduction Manager | Merthyr Tydfil County Borough Council (MTCBC)

JRP understand the support they are asked to give and deliver on time, budget and in a clear concise professional manner. If only everyone was a reliable as JRP!

Jonathan Blair, Technical Advisor | Westons Cider

We are using JRP’s ‘Be Energy’ eLearning awareness course to help us fully meet the ISO 50001 standard. This course is not only getting good feedback from our staff but the external ISO 50001 auditor completed the course and commented that it was ‘the best energy training course that he had seen’. A feather in the cap for JRP.

David Rose, Energy and Carbon Manager | South West Water

JRP were easy to work with and their pragmatic approach to the project was critical to the development of the submission and validation of our SBTs.

Kate Gallacher, Sustainability Officer | Scottish Leather Group

I have been very impressed by the quality of JRP’s work for the University of Oxford, right from the start. All the energy survey reports have been of high quality and tailored to our specific requirements. Many of the recommendations were not identified in previous surveys. JRP is not afraid to ask difficult questions and challenge the status quo. I have worked with and for energy consultancies for more than 20 years and the quality of JRP’s work is some of the best I have seen.

Philip Pike, Energy Manager | University of Oxford

From the outset, JRP provided a clear direction to us. It was beneficial to gain insight from the non-vehicle manufacturing sector and expert knowledge of the FM sector in particular. Throughout the process, JRP has been a guiding hand but who has also listened to our concerns and questions and provided patient answers to our many questions.

Christine Cooke, Senior Manager | Toyota Motor Manufacturing

As a local authority, we needed consultants who could understand the complexities of climate adaptation across our borough – from individuals to communities and businesses of all sizes. JRP stood out for their focus on implementation, building on our existing strategies rather than reinventing the wheel, and developing an actionable plan to help us prioritise climate risks and strengthen resilience for our communities, services and infrastructure. One of JRP’s key strengths was that they did not rely solely on a technical approach and instead, they placed a strong emphasis on engaging communities, partners and residents throughout the process.

Alice Powell, Climate and Strategic Programmes | London Borough of Hounslow

We have achieved over 20% energy savings over the last 12 months and no doubt the training was a contributing factor towards this. I am sure that people are much more energy aware than they were before the training and I would recommend anyone who hasn’t done this sort of training to seriously consider it.

Andrew Smith, Property and Energy Manager | Numatic International

The skill and knowledge that was brought to bear demonstrated a level of sure-footedness that was reassuring. The breadth and quality of the work delivered was exactly what we required.

Ola Bankole, Head of Sustainability | London School of Hygiene and Tropical Medicine

We’ve had the pleasure of working alongside JRP Solutions on numerous ESOS and SECR compliance projects for our clients over the years. Their expertise, attention to detail, and straightforward approach have made collaboration seamless every time. On top of that, they’re a genuinely friendly and approachable team, always happy to discuss the finer details and easy to get hold of when needed. A reliable and knowledgeable partner we’d recommend without hesitation.

Maria Fitzjohn, Key Account Manager | Maximeyes

JRP delivered a comprehensive suite of audits that has really helped to us to improve energy efficiency and reduce costs across our sites. The opportunities identified were used as a platform to enhance our decarbonisation strategy, providing transparency on the technologies available now. JRP’s consultants were friendly, knowledgeable and professional at all times.

Nigel Pounder, Asset Manager | Greencore
