One of the first steps you can take to become more energy efficient at home is to find out what your energy efficiency rating is in the first place. 

What is an Energy Performance Certificate?

An Energy Performance Certificate (EPC) rating provides information on how energy efficient your home is, and in turn the potential energy costs. The coloured chart rates the efficiency of a building from ‘A’ to ‘G’ - with 'A' meaning the building is very efficient.  Properties with a higher rating are likely to have lower fuel bills.*

An EPC also shows how energy efficient a property could be if some improvements are carried out such as replacing lighting with low energy bulbs or upgrading insulation. (Read more on our energy saving tips for your home here).


How to find out your EPC

AIB research* uncovered that only one in five consumers (21%) know how to check their home’s EPC rating.

Thankfully, finding out your EPC rating is easy! All you need to do is enter your postcode on the EPC Register online. **

To show just how easy it is to find out your EPC rating, AIB has teamed up with Serena Terry – better known as TikTok star MammyBanter – to take a look behind closed doors in some popular local homes to help people find their EPC rating. Visit our Instagram page to watch the series. 

If your property doesn’t have an EPC rating on the register don’t worry, you can book an accredited energy assessor to visit the property to carry out an assessment. You can search the Northern Ireland Register to find an accredited energy assessor here.*


A higher energy efficiency rating can come with a host of benefits such as lower household bills.  Check out NI Direct for more information on improving your homes EPC rating. NI Direct also offer a number of grants to help make your home more sustainable and energy efficient.

If your home has an EPC rating between A and B we offer a Green Mortgage with low rates of interest.

Sustainability is at the heart of our business at AIB which is why we are helping our customers fight climate change through green products and services. We are proud to also partner with Trees on the Land, an initiative working to establish young native trees across the island of Ireland. For every Green Mortgage we issue, AIB donates to the project who will in turn plant 10 trees in Northern Ireland.
