Advice on Energy Performance Certificates in NI

Energy Performance Certificates (EPCs) in Northern Ireland
We provide expert advice on Energy Performance Certificates (EPCs) — what they are, why you need one and how to stay compliant when selling your property.

Understanding EPC Legislation
By law, an EPC is required as soon as a property is placed on the market. It must also be made available to any potential purchaser upon request.
The responsibility for obtaining an EPC lies with the property owner or seller and failure to provide one could result in a £200 fine per breach. In addition, a sale cannot legally complete without a valid EPC in place.
Ensuring your EPC is arranged early in the selling process avoids unnecessary delays or penalties later on.

What is an EPC?
An Energy Performance Certificate rates your property’s energy efficiency on a scale from A to G, with A being the most efficient. It also provides recommendations on how to improve your home’s efficiency, reduce running costs and lower its environmental impact.

An EPC helps buyers understand:

• How energy efficient the home is
• The estimated cost of energy bills
• The environmental impact (carbon footprint)
• Potential savings from recommended upgrades
  
  

How is an EPC Calculated?
To obtain an EPC, a qualified Domestic Energy Assessor (DEA) must carry out an inspection of your property.
The assessment typically takes around one hour for an average three bedroom home, depending on the size and layout.
The DEA records detailed information, including:

• Property age and construction type
• Wall thickness and insulation
• Roof insulation depth
• Heating system type, boiler age and efficiency
• Type and quality of windows and glazing
• Floor area and heat loss perimeter
• Type of lighting and number of energy efficient fittings

All this data is entered into government-approved software to generate your final energy rating.

Improving Your EPC Rating
Each certificate includes a recommendation report outlining practical ways to enhance energy efficiency — such as upgrading insulation, installing modern heating systems or switching to low energy lighting.
While these improvements are not mandatory, they can help you:

• Lower energy bills
• Reduce your carbon footprint
• Increase the value and appeal of your home
  
  

Why Your EPC Rating Matters
The average UK home holds an EPC rating of ‘E’, though this varies depending on age, size and construction type.
Even if your property doesn’t score as highly as you’d expect, remember — older buildings often have more limitations on energy upgrades and your rating can always be improved over time.
Prospective buyers can request to see your EPC through your estate agent and many homeowners choose to have an EPC completed even when they’re not selling, to identify opportunities for cost savings and future improvements.
A better EPC rating can also enhance your property’s market value — as energy efficiency becomes an increasingly important factor for buyers.
