About BritTools
BritTools is a free collection of everyday calculators and tools built for people in the UK. No accounts, no subscriptions, no advertising that follows you around the internet — just straightforward tools that do what they say.
The site grew out of a simple frustration: too many calculator sites are cluttered with distracting content, slow to load, and designed more around capturing your data than actually helping you. BritTools is built to be the opposite — fast, clean, and focused entirely on giving you an accurate answer as quickly as possible.
What we cover
We currently offer fifteen tools across five categories:
- Finance — VAT calculator, mortgage repayment calculator, compound interest calculator
- Date — Age calculator, days between dates calculator
- Health — BMI calculator using NHS weight categories
- General — Percentage calculator, tip and bill splitter, unit converter (metric and imperial), password generator
- Word — Scrabble score calculator, word length sorter, vowel and consonant counter, word unscrambler, anagram solver
All tools are designed with UK conventions in mind — VAT rates, NHS BMI categories, pounds and stone, miles and feet — while also supporting metric input where relevant.
How it works
Every calculation happens locally in your browser. Nothing you type is sent to a server. The site uses Google AdSense to display contextual adverts (non-personalised, not based on your browsing history), and Cloudflare Analytics for anonymised page-view counts. There are no cookies used for tracking, no user accounts, and no data retention of any kind.
Accuracy and guidance
Every tool is tested for accuracy, and we update rates and thresholds (such as the VAT registration threshold and NHS BMI categories) when they change. That said, all results are provided for guidance and general information only. For financial, legal, or medical decisions, please consult a qualified professional.
