Do Businesses Need to Disclose Their Carbon Emissions in the UK?

Environmental reporting has become an increasingly important part of corporate governance in the UK. Alongside rising energy costs and growing expectations around sustainability, many organisations are being asked by customers, investors and supply chain partners to demonstrate how they are measuring and reducing their environmental impact.

One of the questions businesses frequently ask is whether they are legally required to report their carbon emissions. The answer depends on the size of the organisation, its legal structure and the reporting frameworks that apply to it.

This guide explains the current reporting requirements in the UK, who they apply to and how commercial solar can support wider carbon reduction strategies.

 

When Is Carbon Reporting Mandatory?

Mandatory carbon reporting in the UK primarily applies to larger organisations.

One of the principal reporting frameworks is Streamlined Energy and Carbon Reporting (SECR), which requires many large UK companies and limited liability partnerships to report information relating to their energy use and greenhouse gas emissions as part of their annual reporting.

Broadly speaking, SECR applies to qualifying organisations that meet at least two of the following criteria:

• Annual turnover exceeding £36 million
• Balance sheet assets exceeding £18 million
• 250 or more employees

Eligibility depends on the specific legal structure and reporting obligations of the organisation, so businesses should seek professional advice where necessary.

Many small and medium-sized enterprises (SMEs) are not currently required to comply with SECR, although they may still choose to measure and report their environmental performance voluntarily.

 

What Information Must Qualifying Businesses Report?

Organisations within the scope of SECR are generally required to report information relating to their energy consumption, greenhouse gas emissions and measures taken to improve energy efficiency.

This commonly includes annual energy usage across buildings and operations, associated greenhouse gas emissions and at least one emissions intensity ratio, allowing environmental performance to be measured relative to business activity.

Qualifying organisations must also describe the actions they have taken during the reporting period to improve energy efficiency. For many businesses, these measures include investments in commercial solar PV, battery storage, building management systems and other energy efficiency improvements.

The purpose of SECR is not only to increase transparency but also to encourage organisations to better understand and manage their energy consumption.

 

Other Environmental Reporting Frameworks

Depending on the size and nature of an organisation, additional reporting requirements may also apply.

Large organisations may be subject to the Energy Savings Opportunity Scheme (ESOS), which requires periodic energy assessments to identify opportunities for improving energy efficiency.

Some listed companies and larger organisations may also report climate-related risks and opportunities using frameworks aligned with the standards published by the International Sustainability Standards Board (ISSB), which have superseded many of the recommendations previously associated with the Task Force on Climate-related Financial Disclosures (TCFD).

The specific reporting obligations vary depending on the organisation and should be reviewed with appropriate professional advisers.

 

Why Many Businesses Report Voluntarily

Even where reporting is not mandatory, an increasing number of organisations are choosing to measure and disclose their carbon emissions.

Customers, investors and procurement teams are placing greater emphasis on environmental performance, while many larger organisations now ask suppliers to demonstrate sustainability credentials as part of tendering and supply chain assessments.

Voluntary reporting also provides businesses with a clearer understanding of where emissions are generated, helping identify opportunities to reduce both carbon emissions and operating costs.

For many organisations, environmental reporting has become an important management tool rather than simply a compliance exercise.

 

Reducing Carbon Emissions Through Better Energy Management

For many commercial organisations, buildings and electricity consumption represent one of the largest sources of operational emissions.

Improving energy efficiency and generating renewable electricity on site can significantly reduce both energy costs and carbon emissions.

Common measures include commercial solar PV, battery storage, energy monitoring systems and wider building efficiency improvements.

Commercial solar is particularly effective because it enables organisations to generate renewable electricity where it is consumed, reducing reliance on grid electricity while providing measurable carbon reductions that can support wider sustainability reporting.

 

Why Carbon Reporting Matters Beyond Compliance

Environmental reporting is increasingly influencing commercial decision-making.

Many organisations now consider sustainability performance when selecting suppliers, awarding contracts or evaluating investment opportunities. Demonstrating measurable progress towards carbon reduction can therefore strengthen competitive positioning while supporting wider ESG objectives.

Although not every organisation is currently required to report emissions, understanding energy consumption and carbon performance is becoming an increasingly valuable part of long-term business planning.

 

How Silvercrest Energy Group Supports Commercial Organisations

Silvercrest Energy Group designs and installs bespoke commercial solar PV and battery storage systems for organisations across the UK.

Our services include commercial feasibility studies, energy consumption analysis, financial modelling, bespoke system design, professional installation and long-term operations and maintenance.

By generating renewable electricity on site, organisations can reduce operational energy costs while making measurable progress towards their wider sustainability objectives.

Although we do not provide carbon reporting or compliance advice, our systems can support organisations seeking to reduce operational emissions as part of broader environmental strategies.

 

Final Thoughts

Carbon reporting is becoming an increasingly important consideration for many organisations, whether through legal obligations, customer expectations or wider sustainability objectives.

For businesses seeking to reduce both operating costs and environmental impact, commercial solar offers a practical way to generate renewable electricity on site while supporting long-term carbon reduction strategies.

A professional feasibility study is the first step in understanding how renewable energy could contribute to your organisation’s operational, financial and environmental goals.
