Stop leaving money on the road.
Many UK workers miss hundreds - sometimes over £1,000 - in unclaimed mileage each year. Trippi connects to your Google or Microsoft calendar and logs business journeys at HMRC rates — no GPS, no app, no manual tracking.
No credit card required. We never track your live location - Trippi only reads calendar events with locations.

Security & privacy
What happens after signup?
Connect your calendar once, confirm your base postcode, and Trippi handles the mileage admin automatically.
Choose your calendar
Start with Google or Microsoft so Trippi knows where your work events live.
Approve read-only access
Grant calendar access via OAuth. We never see your password and you can revoke access anytime.
Set your base location
Enter your home or office postcode. This is the starting point for every return journey calculation.
Trips log automatically
Trippi scans events with locations and calculates business mileage at the end of each day.
Review and export
Edit, delete, mark personal, and export HMRC-ready reports whenever you need them.
Everything you need. Nothing you don't.
Built for anyone in the UK who drives for work.
Calendar-first tracking
No GPS, no app running in the background. We read your calendar events with locations — that's it.
Daily automatic scan
At the end of each day, Trippi scans your calendar and logs every business trip. No manual input required.
HMRC rates built-in
From the vehicle registered in your dashboard, we apply the correct rates automatically — including salary sacrifice and company car schemes where they apply. For privately owned vehicles only: 55p per mile for the first 10,000 miles, 25p thereafter. Tracked per tax year, always up to date.
Export-ready reports
Download CSV or PDF mileage reports formatted for HMRC self-assessment or your account - or even export direct to Xero.
Return journey included
Trippi has intelligence built in to determine whether you're going from A to B or making a return journey — so mileage is logged the way business travel actually works.
Monthly email summary
A simple email at the end of each month telling you how many miles were driven and the claimable value.
Less effort. Better results.

I used to lose track of at least 200 miles a month. Trippi just runs in the background — I connected my calendar once and now everything is logged. My accountant is thrilled.

Common questions
Trippi reads your Google or Microsoft calendar events that have a location attached. At the end of each day, it uses a directions service to calculate the driving distance between your base location and the event location, then logs a return journey. No GPS, no app, no battery drain.
Any calendar event that has a location field filled in. If your event has an address, postcode, or place name, Trippi will detect it and calculate the mileage. Events without locations are ignored.
Yes. Trippi uses the current HMRC-compliant mileage rates: 55p per mile for the first 10,000 business miles in a tax year, and 25p per mile thereafter. We update these immediately if HMRC changes them.
Absolutely. Your dashboard shows every logged trip and you can edit the mileage, add notes, mark as personal, or delete trips entirely. You have full control over what appears in your reports.
Trippi uses OAuth 2.0 for calendar access (we never see your password), encrypts data in transit with TLS and encrypts stored data at rest. We only read calendar event data once per day, never track your live location, and never share your data with third parties.
Yes — every plan starts with a 14-day free trial. No credit card required. If you decide it's not for you, simply don't subscribe. Your data is deleted after 30 days of inactivity.
