New Software is a game changer.

Great news for commercial property owners, over the last few years  the electricity grid has been de-carbonised and electricity now has an excellent carbon emission factor which is much lower than natural gas. The non-domestic EPC rating is based upon the building’s carbon emissions and the new version of the software that generates the rating now reflects this and buildings which use electric HVAC will now typically score much better.

As an example Quidos ran a couple of scenarios on a small 1980s detached building in both the previous version of the software and the new version:

Scenario 1 – Building heated via Electric Panel Heaters
Previous software  EPC rating F142 – New software  EPC rating C75

Scenario 2 – Building heated/cooled via Electric Split System
Previous software  EPC rating C61 – New software EPC rating B30

As you can see the change to the EPC rating in the new software is considerable. Buildings which previously would not have complied with the Minimum Energy Efficiency Standards may now do so with the new version of the calculation engine.

The prospect of having a poorly rated building in recent years was the nightmare that many a property owner lost sleep over. If you need a re-survey done to improve an already lodged commercial EPC certificate please request a quote today.

MEES – EPC regulation changes

The Energy Act 2011

These requirements will then apply to all private rented properties in England and Wales – even where there has been no
change in tenancy arrangements – from 1 April 2020 for domestic properties, and from 1 April 2023 for non-domestic properties.
