About UK Driving Tools
Free calculators and plain-English guides to help UK drivers understand penalty points, fines, road tax and running costs, with the sources behind every figure.
Who Runs This Site
UK Driving Tools is run by me, Prakash. I'm based in India and I don't drive in the UK, so I'm not writing from personal driving experience. I'm not a lawyer, accountant, driving instructor or UK-qualified adviser either.
What I do is take the rates and rules that UK authorities publish, such as GOV.UK, the DVLA, HMRC and Transport for London, and turn them into calculators and guides that are quicker to use than reading the official pages. Each page shows its sources, so you can check any figure yourself.
The site started with penalty points and speeding fine calculators and has grown to cover vehicle tax, EV ownership, family driving costs, business mileage, and buying or selling a used car.
How the Pages Are Made
Pages on this site are drafted with the help of AI tools and then checked by me before they are published. I think you should know that, so here is what it means in practice:
- AI helps with drafting. It is used to structure and write first drafts and to build calculator code.
- Figures are checked against official sources. Rates, thresholds and rules are compared with the official page named on each article or calculator.
- Calculators are tested. The worked examples are run through the calculator's own formula, so the numbers in the text match what the tool gives.
- No invented experience. Pages don't claim personal testing, driving experience or professional qualifications that nobody here has.
You can read the full process in the Editorial Policy.
Why UK Driving Tools Exists
Driving rules and running costs involve numbers most people only need once or twice, and getting them wrong is expensive. Underestimating a speeding fine means a nasty surprise. Not realising your points are close to 12 can mean an avoidable ban. Comparing petrol and electric costs with the wrong charging assumption can make a poor decision look like a good one.
Many free calculators give one number with no explanation. The calculators here aim to include:
- A methodology section explaining the formula and where the rates come from
- Worked examples for realistic scenarios, not just the easy case
- Current rates taken from official UK sources, with the source named
- A "what this can't tell you" section setting out the limits of the calculator
- Links to official sources for anything with legal or financial consequences
Design principle: every page should be useful to someone standing with a Notice of Intended Prosecution in one hand and their phone in the other. If the answer needs a login, a subscription or a law degree to understand, the page hasn't done its job.
Sources the Site Relies On
Each page names the specific sources it uses. These are the main ones:
Legal & Rate Sources
Pricing Data Sources
Please read: every figure on UK Driving Tools is an estimate for planning, based on national averages. Insurance premiums, fuel prices and court outcomes vary by postcode, provider and circumstances. Nothing on this site is legal or financial advice. For anything with real consequences, check with GOV.UK, the DVLA, or a qualified solicitor or adviser.

What I Check Before Publishing a Calculator
- Formula check — compared with the relevant official source (GOV.UK, Sentencing Council, DVLA, HMRC or TfL) and tested against worked examples
- Worked example — at least one full calculation using a realistic scenario
- Rate check — current rates compared with the official tables when the page is published or updated
- Stated limitations — a clear note of what the calculator can't tell you and where to verify
- Updates — pages are corrected when official rates or rules change, and the "Updated" date changes only when the content does
What the Site Doesn't Do
- It doesn't give one confident number where the real answer depends on your circumstances. Results are estimates, not guarantees.
- It doesn't take payment to recommend insurers, solicitors or brokers.
- It doesn't claim to replace official DVLA records, court outcomes or professional advice.
- It doesn't collect personal data beyond what is needed to run the site. See the Privacy Policy.
Estimates, not guarantees. Every result is a planning estimate, not an official record or legal outcome. Use the tools to understand your position, then check anything with real consequences against GOV.UK, your DVLA record, or a qualified professional.
How the Site Is Funded
UK Driving Tools is independently run and paid for by its owner. The site may show advertising, such as Google AdSense, to help cover hosting and development costs. Ads don't affect what the pages say, and no one pays to be recommended.
