Energy Performance Certificates (EPCs)

Do You Need an EPC?

An Energy Performance Certificate (EPC) is not just a regulatory requirement but also an essential tool for anyone involved in the property market. Understanding when and why you need an EPC can help you stay compliant and make informed decisions about your property.

Who Needs an EPC?

Landlords Renting Out a Property: If you are a landlord planning to rent out a residential or commercial property, an EPC is legally required before the property is marketed. This ensures that potential tenants are informed about the energy efficiency of the property.

Homeowners Selling Their Property: When selling a property, an EPC must be provided to potential buyers as part of the sale process. This certificate gives buyers an idea of the energy efficiency and potential running costs of the property.

New Constructions: For newly built properties, an EPC is required upon completion of the construction. This ensures that new buildings meet the current energy efficiency standards.

Major Renovations: If your property undergoes significant renovations that alter the number of parts or heating systems, you will need a new EPC to reflect these changes.

Why is an EPC Important?

Legal Requirement: The most critical reason to obtain an EPC is to comply with UK laws. Failure toprovide a valid EPC can result in fines and legal complications.

Energy Efficiency Insight: An EPC provides a clear picture of your property's current energy efficiency rating. This information is valuable for identifying areas where improvements can be made to reduce energy consumption and lower utility bills.

Marketability: Properties with higher energy efficiency ratings are more attractive to potential buyers and tenants. An EPC can enhance the marketability of your property by showcasing its energy-saving features.

Environmental Responsibility: By obtaining an EPC and following its recommendations, you contribute toreducing carbon emissions and promoting environmental sustainability.

When Do You Need an EPC?

Before Marketing a Property: If you are selling or renting out a property, you must have an EPC available for potential buyers or tenants to view. This is required before you start marketing the property.

At the Point of Construction Completion: For new builds, an EPC is required upon completion of construction. This ensures that the property complies with current building regulations.

Prior to Major Renovations: If you are planning major renovations, it’s advisable to obtain an EPC both before and after the work. This will help you understand the impact of the renovations on the property’s energy efficiency.

What happens during an energy assessment?

The assessment is non-invasive and will not cause any damage to your property and usually takes between 30 mins to 1 hour on a typical property.

The Energy Performance Certificate (EPC) is based upon an assessment of the property carried out by a licensed Domestic Energy Assessor (DEA). The domestic energy assessment involves: Establishing the age and construction method of the property. Measuring floor and wall areas of the property. Looking at heating systems including the boiler, heat emmitters and controls. Identifying existing cavity wall and loft insulation. Identifying any alternative heating (e.g. solar) and energy-efficient products (e.g. energy saving light bulbs). AG Site Solutions will collect specific data on the property as outlined by the Government (RdSAP methodology). This data is then used to produce the Energy Performance Certificate (EPC).The specific information collected by the domestic energy assessor (DEA) includes:

Heating efficiency AG Site Solutions domestic energy assessor (DEA) will evaluate the boiler or the main heating system:
The manufacturer of the boiler.
The model if the boiler has a brand name.
The type of boiler you have, i.e. whether it is combi, condensing, non-condensing or a back boiler.
We will also look at the heating controls within the system for e.g. the thermostat, timer and radiator valves.
This enable us to evaluate the energy efficiency of the combined heating system.

Insulation efficiencyThe domestic energy assessor (DEA) will evaluate the types of insulation installed in your property. Existing insulation is measured and comparedagainst current standards:Loft insulation - The average depth of loft insulation is measured.Cavity wall insulation - The existing cavity wall is examined externally, either visually or by looking inside the cavity to determine whether insulation is present.

Double glazing - The doors and windows will be checked for double's domestic energy assessor (DEA) will all at all times respect your home and answer any questions you may have during the assessment.
