For UK sole traders, claiming mileage expenses correctly can significantly reduce your taxable profits, but keeping an accurate and compliant mileage log is often a headache. HMRC requires detailed records to support mileage claims, and any errors can lead to penalties or lost deductions. Thankfully, modern mileage tracker apps have become indispensable tools, helping you automatically or manually record journeys and generate reports that meet HMRC’s strict standards.
In this guide, we’ll compare three leading mileage tracking apps widely used by UK sole traders in 2026: MileIQ, Driversnote, and FreshBooks. We’ll cover their accuracy, battery consumption, ease of use, and how well their exported reports align with HMRC requirements. Whether you’re a delivery driver, consultant, or side hustler who travels regularly, this guide will help you pick the best app to save money and stay compliant.
Why Accurate Mileage Tracking Matters for UK Sole Traders
Mileage expenses are one of the most common allowable business costs for sole traders. HMRC allows you to claim either a flat rate per mile using the Approved Mileage Allowance Payments (AMAP) rates or actual vehicle costs if you keep detailed records. The AMAP rates for cars are currently 45p per mile for the first 10,000 miles and 25p per mile thereafter within the tax year. To claim these, you must keep a log with dates, mileage, purpose, and start and end locations.
Without accurate and comprehensive mileage logs, HMRC will not accept your claims, which could mean missing out on thousands of pounds in tax relief. Paper logs are time-consuming and prone to errors, especially if you travel frequently. This is why many UK sole traders turn to mileage tracker apps that automate or simplify the process, producing HMRC-ready reports that can be submitted with your Self Assessment.

MileIQ is one of the most popular mileage apps worldwide and has grown in popularity among UK sole traders for its automatic trip detection and classification features. It runs in the background and uses your phone’s GPS to detect when you start and end a journey, logging the route and distance without any manual input.
The app allows you to classify trips as business or personal with a simple swipe, and it remembers frequent routes to speed up classification. It also generates detailed reports showing each journey’s date, mileage, and business purpose, formatted to meet HMRC’s record-keeping requirements.
However, the automated GPS tracking can drain your phone’s battery faster, especially if you travel daily. Some sole traders report needing to charge their phones more frequently when using MileIQ. On the upside, its accuracy is generally excellent, with minimal missed trips or incorrect distances, which is crucial for HMRC compliance.
- Automatic detection of trips with minimal manual input
- Easy swipe classification for business or personal use
- Detailed, HMRC-compliant exportable reports
- Higher battery usage due to constant GPS tracking
If you use MileIQ, be prepared for increased battery consumption. Consider carrying a portable charger or using a car charger to avoid disruptions during busy travel days.
Driversnote: Balanced Manual and Automatic Tracking with Strong Reporting
Driversnote is a UK-friendly mileage app designed for sole traders who want a mix of automation and control. It automatically detects trips but also allows easy manual adjustments or additions, making it flexible if you forget to track a journey or want to add extra notes.
One of Driversnote’s standout features is its powerful reporting system. You can generate detailed mileage logs tailored to HMRC’s requirements, including start and end locations, dates, mileage, and purpose. The app also supports exporting reports in multiple formats like PDF and Excel, which many accountants appreciate.
Battery consumption is generally lower than MileIQ because Driversnote uses a hybrid tracking method that balances GPS and accelerometer data. This makes it a good choice for sole traders who want accuracy without constantly worrying about phone battery life.
- Hybrid tracking reduces battery drain while maintaining accuracy
- Easy manual editing and adding trips
- Multiple export formats suitable for HMRC and accountants
- Good UK-specific features including AMAP rate presets
Set up your business vehicle(s) in the app with correct AMAP rates. Regularly review and classify trips to keep your log accurate. Export reports quarterly to avoid last-minute Self Assessment stress.
FreshBooks Mileage: Mileage Tracking Within a Full Accounting Ecosystem
FreshBooks is primarily an accounting and invoicing tool, but it includes a mileage tracking feature aimed at simplifying expense management for sole traders and freelancers. It is especially useful if you want to integrate mileage costs directly into your overall bookkeeping.
The mileage tracker in FreshBooks allows you to log trips manually or automatically, but it is less sophisticated than dedicated mileage apps. Its main strength lies in linking mileage expenses directly to client projects and invoices, which can streamline billing and tax reporting.
While FreshBooks does generate reports, they are not always as detailed or specifically tailored for HMRC mileage claims compared to the likes of MileIQ or Driversnote. This means you might need to supplement your mileage tracking if you want to ensure full compliance.
- Integrated with accounting and invoicing for seamless expense management
- Supports manual and some automatic mileage tracking
- Good for sole traders who invoice clients for travel expenses
- Reports less detailed for strict HMRC mileage record requirements
Founder Insight: Sarah Mills, a freelance marketing consultant based in Manchester, shares, “I switched to FreshBooks because it keeps all my business finances in one place. The mileage tracking isn’t perfect for HMRC claims alone, but when combined with my invoices, it saves me hours on bookkeeping.”
Comparing Mileage Accuracy and HMRC Compliance
Accuracy in mileage tracking is non-negotiable when submitting claims to HMRC. Inaccurate logs can lead to rejected claims or audits. MileIQ’s continuous GPS tracking offers near-perfect route recording, which is why it’s preferred by sole traders who drive extensively. Driversnote’s hybrid approach slightly compromises on absolute automation but maintains reliable accuracy with less battery impact.
FreshBooks, while convenient, may require users to cross-check trip details manually or keep supplementary records to satisfy HMRC’s requirements. If you rely heavily on mileage claims, pairing FreshBooks with a dedicated mileage tracker might be necessary.
- MileIQ: Best for automatic, accurate tracking but higher battery use
- Driversnote: Balanced accuracy with lower battery consumption and strong reports
- FreshBooks: Best for integrated accounting but less tailored mileage records
Keep your mileage logs up to date weekly and back up your app data regularly. Inaccurate or missing records can cost you hundreds or thousands of pounds in missed deductions every tax year.
Practical Tips for Using Mileage Tracker Apps as a UK Sole Trader
- Choose an app that fits your travel frequency and phone usage habits.
- Set up your business vehicles with correct AMAP rates in the app settings.
- Classify trips as business or personal immediately after each journey to avoid forgetting.
- Export mileage reports regularly (quarterly or monthly) to simplify Self Assessment submissions.
- Keep a manual backup log or spreadsheet as a fallback against app errors or data loss.
- Consult an accountant if you have complex vehicle use or want to maximise allowable expenses.
Many sole traders find that combining a reliable mileage tracker with professional advice ensures they claim the maximum allowable expenses without risking non-compliance. Remember, HMRC can request your mileage logs up to six years after the end of the tax year, so keeping accurate, backed-up records is essential.
Final Verdict: Which Mileage Tracker Is Best for You in 2026?
If your priority is automatic, highly accurate mileage tracking and you don’t mind managing your phone’s battery life, MileIQ remains a top choice for UK sole traders. Its reports are ready for HMRC submission and help you stay audit-proof.
For a more balanced approach that reduces battery drain and offers excellent export options tailored for UK tax rules, Driversnote is a strong contender. Its hybrid tracking suits those who want some manual control without losing automation benefits.
If you want to streamline your entire business accounting process and only occasionally track mileage, FreshBooks might be the best fit. Just be prepared to supplement mileage tracking for detailed HMRC requirements.
Choosing the right mileage tracker app ultimately depends on your business travel habits, how you manage your accounts, and your appetite for manual input versus automation. Whichever you choose, keeping detailed, accurate mileage records is one of the smartest ways to maximise your tax efficiency as a UK sole trader.
