Energy Performance Certificate – a breakdown

Not All EPCs are the same with consistencies as follows for each:

  1. The date of validity, so the exact date your EPC will expire
  2. A certificate number
  3. A description of the property
  4. Total internal floor area, based on measurements taken by the assessor at the time of their visit
  5. The EPC will then be broken down into the following main sections:

1. Current and potential energy costs

The first section of an EPC looks at the house’s estimated costs for energy divided into lighting, heating and hot water currently. This is useful to know how much a property’s energy utility bills will be and how much you could save. It is worth noting that this is an estimate of costs and not based on energy used by individual households. It excludes energy used for running appliances, such as computers, cookers, fridges and TVs, so your bills will likely be higher. The estimates shown are useful if you are comparing properties, so you can see which one will be cheaper to run.

2. Energy efficiency rating

The next table will show which EPC rating your property has and looks similar to the energy labels on home appliances. The rating is from A to G, with A as the most efficient and cheapest to run. It also shows the potential rating if you were to make the suggested improvements. Some EPCs will have a similar table, showing the property’s environmental performance. This will show how the building performs in terms of carbon dioxide emissions. Again the best rating is A and the worst is G. It will again show the potential which could be achieved if changes were implemented.

3. Performance

The next part of your certificate will give you a breakdown of each element of your property, including your walls, roof, floor, windows, main heating, main heating controls, secondary heating, hot water, and lighting. After each of these will be a description and a rating. This is sometimes given from one to five stars, with five being the best. Or it will be given from Very Poor to Very Good. This part of the EPC can help you understand how effective the construction of the property is, as well as the heating and hot water system, and lighting.

4. Recommendations

This important part of the EPC lists a breakdown of recommended measures, including the related costs and typical savings that you could make. It will show how each measure could improve the energy efficiency of the property and now this could improve the rating. The recommended measures are shown in order of importance and the improvement figures are based on making changes in this order. The number of recommendations will vary.
