What People Say About Kilowatt.ie
“After stumbling across this website when trying to muddle through the maze that is other comparison websites, Kilowatt gave me the real information I needed to understand the Trapdoors & know exactly which provider was offering. I won’t be switching again without checking in on Kilowatt. I was curious about solar panels & the website also gave me a lot of information about what works & doesn’t & how to get the information required to make a good decision on a solar investment.”
Feb 2026“Kilowatt.ie is a very effective comparison tool, especially for households with solar, a battery, an EV or a heat pump. It’s great that you can adjust the dates each system was installed, tailor the heat-pump settings based on your home’s square metres, and include your daily EV kWh usage — the level of detail makes the results far more accurate. The new Summer/Winter split feature is also a smart addition, clearly showing how the best tariff can change throughout the year even factoring in the two early exit fees per year to stick to such a schedule. Dominic continues to add meaningful upgrades that reflect how people use electricity today. Highly recommended for anyone wanting a clear and realistic view of their best tariff.”
Nov 2025“While I have a good understanding of the different concepts of solar panels and electrical usage, it was great to finally see a comparison site which takes the main factors into consideration, the house size, heating source, amount of solar panels, size of battery storage.. all play a major part so I was delighted to be able to compare all these in one place rather than just using national averages like other sites.. great website, highly recommended!!”
