Energy Performance Certificates - EPC

What is an EPC?

As a landlord, you are legally required to obtain an Energy Performance Certificate (EPC) for your property.

An EPC estimates how much it costs to heat and power a building. The report also provides recommendations for improvement and the resulting cost savings you can expect.

The types of EPCs:

EPCs are categorised by property type and purpose. A rating of A to G is given, with A being the most energy efficient and G the least. The report also shows the property’s carbon dioxide (CO2) emissions.

Domestic EPC

Single-family homes rented or sold are required to obtain a domestic EPC, regardless of the property’s size. Exceptions to this rule include some listed structures, temporary structures that will not be used for more than two years, and holiday rentals let out for less than four months in a year.

Commercial EPC

These are required for selling, letting, or constructing commercial buildings. It outlines the energy efficiency of the property to prospective buyers or tenants. However, you do not need an EPC if you could prove the building falls under any of the following:

  • Listed as a heritage site
  • Intended to be used for less than two years
  • Used as a place of worship or a religious setting
  • An industrial site, non-residential agricultural building or workshop that doesn’t consume much energy
  • A detached building with a floor space not exceeding 50 square metres
  • Scheduled for demolition by the landlord or seller with all essential planning and conversation consents obtained


A Standard Assessment Procedure or SAP measures a property\’s energy efficiency and CO2 emissions. It is applicable for newly constructed, converted and extended residential properties.

Unlike domestic and commercial EPCs, SAPs do not require an on-site visit. You simply need to provide documents like your architect\’s blueprints and construction specification details.

Why your property needs an EPC?

For landlords and owners, EPCs make a property more attractive to potential tenants and buyers. Prospects are now looking for energy-efficient homes to save on their utility bills. You can show that your property meets these standards with an EPC.

Meanwhile, tenants can use an EPC to see how much it costs to heat and power a rental unit. The report also provides recommendations on how they can save energy and money.

Lastly, an EPC is required by law when selling or letting a property.

If you do not have one, you could face a fine of up to £5,000.

What to expect during an Inspection

Domestic assessments take a minimum of 30 minutes, while commercial inspections can last up to 45 minutes.

However, the time required for an evaluation also depends on the size and complexity of the property.

EPC assessments are conducted by a qualified energy assessor. They will visit the property to collect data on its construction, size, and use. Photo evidence may also be gathered during the inspection.

The assessor will take note of the following:

Windows | Lighting | fixtures | Boiler | Insulation | Water tanks | Energy-saving measures  i.e., solar panels

After the inspection, the assessor prepares a report outlining the property’s energy rating and CO2 emissions. The document will also include recommendations on how to improve the property\’s energy efficiency.

A copy of the EPC will be lodged in a national database where interested parties can access it. The results are available to the public. In some cases, the government can also use them for research or statistical purposes.

How often should you schedule an EPC Inspection?

Energy Performance Certificates are valid for ten years. However, we recommend you get a new assessment if there are significant changes to the property, such as renovations or the installation of energy-saving features.

This is to ensure that the EPC accurately reflects the current energy efficiency of the property and you’re up to code with current legislation.
