Who runs the site
Garden Sums (gardensums.co.uk) is run by Fernando Margareto, Yátova (Valencia), Spain. Contact details are in the legal notice.
Using the calculators
The calculators are free to use for your own projects, at home or at work. The results are estimates based on the measurements you enter and on typical figures published by UK manufacturers and suppliers. They are not a quotation, a design or professional advice. Please read the disclaimer before relying on a result, and check quantities with your supplier before you order.

Content and ownership
The text, calculators, code, diagrams, logo and photographs on Garden Sums are the work of Fernando Margareto and are protected by copyright. You may link to any page and quote short extracts with a link back. Product and brand names mentioned on the site belong to their owners and are used only to describe the sources of published figures.
Links to other websites
Some pages link to other websites. Garden Sums does not control them and is not responsible for their content or for how they handle your data.
Availability and changes
The site is provided as it is, and it may change, move or be unavailable from time to time. Figures are updated when better sources appear, so a result can change between visits. These terms may also change; the date below shows the last update.
Liability
Garden Sums takes care to keep its figures accurate and its sources up to date, but cannot guarantee that a result is right for your project. As far as the law allows, Fernando Margareto is not liable for losses that come from relying on a result, including materials ordered in the wrong quantity, delays or costs of extra work. Nothing in these terms limits liability that cannot be limited by law, or takes away rights you have as a consumer.
Law
These terms are governed by Spanish law. If you live in the UK or elsewhere, you keep any protection that the law of your country gives you and that cannot be excluded, and you may bring a claim in your own courts where that law allows it.
