About Energy Saving Trust

Energy Saving Trust is an independent organisation dedicated to promoting energy efficiency, low carbon transport and sustainable energy use. We aim to address the climate emergency and deliver the wider benefits of clean energy as we transition to net zero. We empower householders to make better choices, deliver transformative programmes for governments and support businesses with strategy, research and assurance – enabling everyone to play their part in building a sustainable future.

We are independent and impartial, so the advice we give is all about helping you. Energy Saving Trust will treat any personal data you provide us carefully and securely.

Energy Saving Trust does not make cold calls (we do not sell insulation or solar panels, etc). If you are receiving cold calls from an organisation, the Information Commissioner’s Office has some useful advice and, if you haven’t already, it may be worth considering registering with the Telephone Preference Service.
