How To Get An A Rating On Domestic Energy Performance Certificate?

Getting an A on your Energy Performance Certificate is incredibly difficult and may even be impossible for some features. In this blog, we want to give you an idea of ​​what it takes to get an A rating for a home and what you can possibly do to get your home close to that level.

The average British rating

The typical property in the UK has a rating of around 60, which results in a D rating. A B rating requires a score of 81, while an A needs 92. New-build properties that are on the market today must be at A level or slightly lower than B. Most older properties will be much lower.

Improve the assessment with documentation

If you have an existing property with a low rating, it is sometimes possible that the existing EPC used some default values ​​in the calculations. This usually happens when an EPC is performed quickly and with little communication or disinterest from the customer. If model numbers and insulation values ​​can be added to the report, the rating is likely to rise, in some cases with large margins. To add this information, documentation demonstrating what is installed must be made available to the assessor.

Renewable technology

Although insulation and model numbers are likely to lead you to a better rating, there is little room for poor performance for the best ratings. The following must be present as a starting point to get the highest rating:

High insulation thicknesses throughout the building, in the roof, the walls, and the floor. This is essential and the levels will probably have to exceed even the strictest building codes.

High-quality heating system — you need a modern condensing gas boiler with a good control system, or a renewable heating system if you are not connected to the grid.

Windows must be modern double or triple glazing.

All this will probably give you an Energy Performance Certificate B rating if fully installed and documented throughout the building. To get an A, you probably need some sustainable energy generation — this means practically solar or wind energy. If you live in a rural area, wind may be a good option, but for most people, solar energy is the best way to produce your own electricity.

Can your EPC be over 100?

In theory, the EPC scale rises above 100. In practice, there are probably only a handful of properties throughout the UK that achieve this type of assessment. They would require a significant renewable generation and create more energy than the building itself needs

Receive a recommendation report

If you doubt whether the improvements will be sufficient to get the required assessment, you can always engage an energy assessor to perform an EPC without submitting the resulting report. The information collected can then be used to determine exactly what is needed to get the desired assessment.
