What Is an Energy Performance Certificate?
An Energy Performance Certificate (EPC) is an official document that rates the energy efficiency of a property on a scale from A (most efficient) to G (least efficient). It provides a clear picture of how much energy your property uses and what it costs to heat and power.
Beyond compliance, an EPC provides valuable recommendations on how to improve your property’s energy efficiency. This helps reduce energy bills, lower your carbon footprint, and increase your property’s market value.
In the UK, an EPC is a legal requirement whenever you sell, rent, or build a property. Landlords must provide an EPC to prospective tenants, and sellers must make one available to potential buyers before marketing their property. Without a valid EPC, you could face fines of up to £5,000.

Who Needs an EPC?
If you’re selling, renting, or building a property in the UK, you legally need an Energy Performance Certificate.
Landlords
A valid EPC is mandatory before letting a property. Ensure your rental meets the minimum E rating to avoid penalties.
Homeowners Selling
An EPC must be available to prospective buyers from the point of marketing. A good rating can boost your sale price.
Commercial Property Owners
Non-domestic EPCs are required for commercial properties being sold or let. We cover offices, retail, and industrial units.
Letting Agents
Agents must ensure a valid EPC is in place before marketing a property for rent. We offer fast turnaround for agencies.
New Build Developers
New constructions require an EPC before occupation. We work with developers to ensure SAP assessments and compliance.
Why EPC is Important
Gas safety isn't just a legal requirement—it's a critical measure to protect lives and property. Understanding the risks helps you make informed decisions about your home's safety.
Why Energy Efficiency Matters
A good energy efficiency rating doesn’t just lower your bills — it enhances comfort, reduces carbon emissions, and increases property value. Whether you’re selling, renting, or looking to improve your home, understanding your property’s energy performance is key.
Lower Energy Bills & Carbon Emissions
Properties with high efficiency (like A or B on the EPC scale) use less energy for heating and lighting, meaning lower monthly energy costs and a smaller carbon footprint.
Better Market Value & Tenant Appeal
An efficient home is more attractive to buyers and renters. Having a strong EPC rating can make your property stand out — and potentially increase its market value or rental appeal.
Regulatory Compliance for Renting or Selling
For landlords or sellers in the UK, a valid EPC is often legally required before marketing a property. Ensuring compliance avoids fines or legal issues.
Don’t Wait — Upgrade and Save
If your property has a low EPC rating (E, F or G), consider upgrading insulation, heating, windows or other efficiency improvements. A small investment now can boost your rating, reduce bills, and increase your home’s value.

Current Rating
Your current EPC rating reflects the energy efficiency of your property as it stands today. This is based on factors like insulation levels, heating systems, glazing, and lighting.
Potential Rating
The potential rating shows what your property could achieve if all recommended improvements were implemented. This helps you prioritise upgrades for maximum impact.
What Affects Your Score?

Frequently Asked Questions
Have questions about our compliance and energy efficiency services? We’ve answered the most common queries below to help you understand our process, legal requirements, and how ECOCS can support your property needs.
How long does the on-site assessment take?
For most standard properties, the survey takes between 30 and 60 minutes. Larger or more complex properties may take slightly longer.
How can I improve my EPC rating?
Common and effective ways to improve your rating include installing loft and cavity wall insulation, upgrading to double or triple-glazed windows, installing a modern A-rated condensing boiler, and switching to low-energy LED lighting.
What happens if my property gets a rating of F or G?
If you are a landlord, you will be legally required to make improvements to bring the property’s rating up to at least an ‘E’ before you can let it. We can provide guidance on the most cost-effective ways to achieve this.
