Terms of Use

Who we are

businesssolarcalculator.co.uk is operated by SEO Dons Ltd, 71-75 Shelton Street, Covent Garden, London WC2H 9JQ. Company No. 16766013. By using this website you accept these terms.

The calculator provides estimates, not advice

The solar calculator and all figures on this site are indicative estimates built from published assumptions. They are provided for general information and are not financial, tax, legal or engineering advice. Actual system costs, generation, savings and payback depend on site-specific factors — roof condition, shading, load profile, grid connection and contract rates among them — that no online tool can assess. Obtain a professional survey and, where relevant, advice from your accountant before committing to any investment. Tax content, including descriptions of the Annual Investment Allowance and first-year allowances, summarises rules that change; confirm current treatment with HMRC guidance or a qualified adviser.

Accuracy and updates

We work to keep cost bands, yields and rates current and we correct errors when they are pointed out. We do not warrant that any figure is error-free or current at the moment you read it, and we accept no liability for decisions made in reliance on the site's estimates. Nothing in these terms limits liability that cannot lawfully be limited.

Quote requests

Submitting the quote form requests that we and a vetted UK installer prepare an indicative proposal for you. It creates no obligation on you to proceed and no obligation on us or any installer to make an offer. Any subsequent contract for survey or installation is between you and the installer on that installer's terms.

Intellectual property and acceptable use

The content, design and calculator implementation on this site belong to SEO Dons Ltd. You may use the calculator freely for evaluating your own or your organisation's premises, and quote our published figures with attribution and a link. You may not scrape the site at scale, republish substantial parts of it, or present our tool as your own. Do not submit the quote form with false details or on behalf of someone who has not consented.

Links to other sites

Pages on this site link to external resources, including GOV.UK guidance and related commercial solar websites operated within our portfolio. We are not responsible for the content of external sites.

Governing law

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction over any dispute arising from them or from use of this website.
