Solar Panels.
Solar panels are often the first upgrade people consider when thinking about improving their household’s energy efficiency. A properly sized and installed array of solar panels takes approximately 6.5 years to pay off. Every solar panel installer that we recommend use panels that have a 25-year minimum warranty, meaning that you will receive free electricity for at least 18.5 years – not bad, eh?
When it comes to going solar, is it critically important to avoid low quality installers. We highly recommend taking our online solar assessment and choosing from our meticulously vetted selection of reliable solar installation companies.

Energy Price Comparison.
Switching your electricity and/or gas supplier can be one of the fastest ways to reduce your energy bills. On average people save around €300 per year by switching to a cheaper plan, but unfortunately only 20% of households switch each year, meaning that almost 80% of households are overpaying every month for their energy.
Energy discount generally apply for the first 12 months after you switch, but after this period, you revert to a more expensive plan. This is costing households an estimated €200-300 million euro per year in excess energy costs.
Our goal is to provide free information to help consumers make more informed decisions and make energy switching easier than ever before.

Everyone with an electric vehicle should install an EV charger at their home for a variety of reasons. Home EV charging (particularly at night) is a low cost, environmentally friendly way to power your vehicle.
