How is EPC band calculated

The epc certificate is a proof of the efficiency

The Energy Performance Certificate (EPC) is an easy method to assess the efficiency of your home’s energy use and carbon emissions from your home. It’s an essential legal requirement when you’re building, selling or leasing residential or commercial properties.

The epc certificate is a proof of the efficiency of your home through bands that vary from ‘A’ up to “G”, giving a concise overview of your building and providing suggestions on enhancements you can do to boost the quality of your EPC rating.

How do these bands come to be determined and what are they? Let’s look at.

What do you think of the energy efficiency bands?

The energy efficiency bands allow you understand the efficiency of your home from an instant. There are seven bands in an EPC that are displayed in a sliding scale ranging starting with the ‘A’ rating (the most efficient) to “G” (the most inefficient). They also have a colour code for easy reference. They range from dark green (an A rating) all the way to red (a “G” rating). Find some of the best epc certificate near me

In addition to the energy efficiency and energy efficiency, you’ll also receive an environmental impact score that is based on the same scale. The highest rating being an A (with the light blue hue) and the lowest rating being is a “G” (with dark grey colours).

What are the energy efficiency bands how are they calculated?

For calculating the energy efficiency of your home an assessor who is qualified will visit your home and assess a variety of variables to help you know how energy is used within your home. This will include the possibility of loss of energy or heat and assessing the insulation in the house, assessing how efficient your heating system and water are and determining if you have double-glazing and efficient lighting bulbs, and more.

Every stage of the inspection will be awarded an assessment based on the efficiency and in what condition it’s. The assessor will calculate how energy efficient your property is, and give an EPC rating for your property.

They are graded based on the points system, which operates in the following manner:

  • EPC score A is 90-100 SAP points

  • EPC Rating B = between 81 and 91 SAP Points

  • EPC score C equals 69-80 SAP point

  • Rating EPC D= 55-68 SAP Points

  • EPC Rating E= 39-54 points SAP

  • Rating EPC F = 21-38 points SAP

  • Rating G for EPC = 1-20 SAP point

After this is done after which you will be issued the Energy Performance Certificate which will provide details on the efficiency of your energy use and the environmental impact of your home.

Additionally, you’ll find details including estimated energy usage carbon dioxide emissions fuel prices, a comprehensive overview of your home, and suggestions for what can be done to improve the value of your EPC bands calculation. Some of the approved local assessor

What is this saying for your home?

If you’ve were able to have an EPC carried out on your property but didn’t receive the results you were expecting do not panic. There are a variety of ways you can increase the efficiency of your house and increase your score, and most of them are cost-effective.

For instance, you could change your light bulbs with LEDS, buy an intelligent electricity meter and think about replacing your boiler, purchase double-glazed windows, and think about the use of solar energy in all places.

It is also important to remember this: the EPC is a legal requirement under law in both the residential and commercial sectors which is subjected to ever strict guidelines.

For instance, new regulations known as” the minimum energy efficiency standards (MEES) came into effective in April 2018, which means that landlords who have the EPC rating of “F” or “G” aren’t permitted to renew leases until they upgrade the property to at least the ‘E’ rating.

The same applies to all tenancies beginning 1 April 2020. This will tighten even more by 2030, when the EPC minimum band is set to be “B”. 

Be aware that the EPC isn’t here to make you feel guilty. It’s an excellent opportunity to understand the efficiency of your home’s energy use and the green credentials of your house and to make a positive impact to ensure the sustainability of our planet.


To summarize to recapitulate, to recap, EPC bands are determined by performing a non-invasive assessment of your home and assigning each component a distinct score.

When the entire property has completed its green energy audit completed, it will be assessed and the EPC bands will be determined. It will give you a rating, as well as useful details on what could be altered in your home to increase the EPC band, and aid in the fight against climate change. Check out some best epc cost
