CAT Information team

Free advice from our Information Service – The CAT Information Service answers queries on a wide range of subjects including renewable energy, energy efficiency, climate change, environmental building and water use/treatment. The recent introduction of the government’s Feed-in Tariff and RHI schemes have created a tremendous interest in domestic-scale renewable energy (e.g. solar panels), and CAT’s 40 plus years of experience with this technology put us in an excellent position to advise householders on making the most of these opportunities.
