Energy Performance Certificates

Maximise the value of your buildings.

commercial EPC assessor

In an increasingly competitive property market, ensuring your real estate has a strong energy rating is becoming more important than ever. A building’s energy performance can significantly influence its rental and sale value, while also helping occupiers reduce exposure to rising energy costs and future compliance risks.

Energy Performance Certificates (EPCs) indicate the intrinsic energy performance potential of a building using a rating system from A to G, where A represents the highest level of efficiency and G the lowest.

If you require an Energy Performance Certificate, our experienced commercial EPC assessor team can help certify your property quickly and efficiently, while also providing practical guidance on how to improve building performance and maximise asset value.

We offer a range of energy management and compliance services designed to simplify regulatory obligations, reduce energy consumption and support long-term sustainability goals. Our approach helps organisations improve building performance while reducing carbon emissions and supporting their journey towards net zero.

Compliance requirements

Understanding how EPC ratings affect compliance, leasing and long-term property performance can help you manage risk, plan improvements and future-proof your building portfolio.

An Energy Performance Certificate is required by law when constructing, selling or letting a commercial building larger than 50m². Failure to comply can result in fines of up to £5,000.

Every EPC should be lodged on the Government Central Register, allowing stakeholders to complete an EPC ratings check and verify compliance. Our comprehensive service covers all your EPC requirements, helping ensure your buildings remain compliant and commercially attractive.

A non domestic energy performance certificate provides a standardised assessment of how efficiently a building is expected to use energy. It also includes recommendations for improving energy performance and reducing operating costs.

For landlords, investors and asset managers, EPCs have become increasingly important due to evolving Minimum Energy Efficiency Standard (MEES) regulations. A poor EPC rating can affect the ability to lease a property and may require improvement works to remain compliant in future years.

Working with an experienced EPC assessor helps ensure assessments are completed accurately while identifying opportunities to improve ratings and future-proof property portfolios.

Types of Energy Performance Certificate

Our Compliance EPC service is designed for building owners, landlords and letting agents who require a fast, reliable and cost-effective solution to meet legislative requirements.

A site survey is undertaken to assess the building and identify energy performance characteristics. Our commercial EPC assessor team then compiles the required information and produces the EPC efficiently, helping minimise delays and ensure compliance with current regulations.

This service is available for both commercial and domestic properties.

Our Optimisation EPC service is designed for developers, landlords, managing agents and property owners seeking to maximise the value of their building assets.

The service includes virtual EPC modelling, allowing our specialists to identify the most cost-effective improvement measures capable of significantly improving EPC asset ratings. Research has shown that energy performance improvements can increase property values by as much as 15%.

Beyond compliance, this service helps organisations understand how strategic energy improvements can support long-term asset performance, reduce operating costs and deliver measurable returns on investment.

Our New Build EPC service provides a fast and efficient solution for new developments.

EPCs can be produced using architectural drawings, building services plans and supporting information, removing the need for a full site survey during construction. Additional information can be collected through telephone or electronic surveys where required to complete the EPC calculations and mandatory Recommendation Report.

This streamlined process helps developers achieve compliance efficiently while maintaining project timelines.

Key features and benefits

Maintain compliance

Our comprehensive EPC service helps organisations remain compliant with current legislation and avoid costly penalties.

By working with an experienced commercial EPC assessor, building owners can ensure certificates are produced accurately, lodged correctly and available whenever required for property transactions or compliance reviews.

Maximise the value of your buildings

A strong EPC rating can improve the attractiveness of a property to tenants, investors and purchasers.

Understanding improvement opportunities through a professional EPC ratings check can help organisations prioritise investments that improve energy performance, increase asset value and support future compliance requirements.

Experience at your fingertips

Our service combines technical expertise, site investigations, virtual EPC modelling and strategic advice to deliver practical outcomes.

Unlike a basic compliance assessment, our commercial EPC assessor team helps clients understand not only their current rating, but also the most effective route to improving building performance and future compliance resilience.

Why choose Zenergi as a commercial EPC assessor?

Choosing the right EPC assessor is about more than obtaining a certificate.

It is about understanding the wider implications of energy performance for compliance, asset value and long-term building strategy.

Our specialists combine EPC expertise with broader knowledge of compliance frameworks, energy management and building performance. This allows us to provide a more strategic service that supports both immediate compliance requirements and longer-term improvement objectives.

Whether you require a single assessment, portfolio-wide support or guidance on future MEES requirements, our team delivers a practical and commercially focused approach tailored to your organisation.

We also provide clear advice around the cost of EPC assessments and improvement options, helping clients make informed decisions that balance compliance, investment and operational performance.

Need an Energy Performance Certificate for your building or portfolio?

Our experienced commercial EPC assessor team can help you meet compliance requirements, understand your current rating and identify practical steps to improve building performance.

FAQs

An Energy Performance Certificate measures the energy efficiency potential of a building and provides a rating from A to G along with recommendations for improvement.

An EPC is required when constructing, selling or letting most commercial buildings over 50m².

A qualified commercial EPC assessor or accredited EPC assessor must carry out the assessment and lodge the certificate on the Government Central Register.

An EPC ratings check can be completed through the Government Central Register, where lodged certificates can be viewed and verified.

The cost of EPC assessments can vary depending on factors such as building size, complexity, location and the type of property being assessed.

A non domestic Energy Performance Certificate applies to commercial properties and is required when buildings are sold, let or constructed. It helps demonstrate compliance and provides insight into future improvement opportunities.
