Terms of use
The small print for using this website. Plain English, no surprises.
Last updated: 5 October 2026
Who we are
This website is operated by Proudly Powered Ltd, trading as Proudly Powered (Company No. 17311174). By using the site you agree to these terms.
Prices, savings and the calculator
Every price on this site is a typical range, and every savings figure is an estimate built from stated assumptions (shown under the calculator and in each guide). They are there to help you decide whether to ask for a quote. They are not an offer, and the only price that binds either of us is the written quote you receive after a survey.
Savings depend on your roof, your usage, your tariff and the weather, none of which we control. Payback periods are illustrative and not a guarantee of financial return.
Who installs
Proudly Powereddesigns, sells and project-manages energy systems. Installation is carried out by MCS-certified partner engineers under their own certification. Product warranties are provided by the manufacturers on the terms they publish. Where this site quotes a manufacturer’s figure (for example EcoFlow’s warranty or cycle rating) it is their claim, attributed to them, and subject to their terms.
Grants and VAT
Statements about 0% VAT, the Smart Export Guarantee and grant schemes reflect our understanding of the rules at the date above. Schemes change. We confirm what applies to you in your quote, and nothing on this site constitutes financial advice.
Using the site
You may read and share pages for personal, non-commercial use. You may not copy the site’s content, design or code for commercial purposes, scrape it, or use the enquiry form to send anything other than a genuine enquiry. We may change or remove any part of the site without notice.
Liability
We take care to keep the site accurate, but we do not guarantee it is error-free or always available. To the extent the law allows, we are not liable for loss arising from your use of the site or reliance on its content. Nothing in these terms limits liability for death, personal injury or fraud, or your statutory rights as a consumer.
Law
These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction.
