Using this website
By using healthcalculators.co.uk you agree to these terms. If you do not agree, please do not use the site.
Health guidance, not a diagnosis
All calculators and content are for general interest and guidance only. They are not a substitute for professional medical advice, diagnosis or treatment, and they do not know your history. Always speak to your GP, a pharmacist, your midwife, NHS 111 or another qualified professional about your health, and never delay getting help because of a result here. In an emergency, call 999.
Accuracy
We use established formulas and published UK guidance, show the working and link the sources. Results are still estimates, and people vary. We do not guarantee that any result is accurate or right for you.
Alcohol and driving
Blood alcohol and units tools are rough guides only. They can never tell you that you are safe to drive. The only safe amount before driving is none.
Our content
The design, branding and original text belong to R&B Digital Ltd. You are very welcome to link to any page. Please do not scrape or republish content in bulk without permission.
Liability
To the fullest extent the law allows, we are not liable for any loss arising from relying on calculator results or site content. Nothing in these terms limits liability that cannot be limited by law.
Changes and law
We may update these terms, and the date at the top will change when we do. These terms are governed by the law of England and Wales.
