Log every business journey from inspections, and contractor visits, to viewings and DIY stops. Calculate the driving distance automatically, then apply HMRC's flat mileage rate (55p/mile for the first 10,000 miles) to see your total deduction. Download a tax-ready PDF in three clicks.

Enter the start and end address for each journey - the tool works out the exact driving distance from mapping data. Add the date, the business purpose, and whether it was a return journey. Repeat for as many journeys as you need, then download a PDF expense pack with your total mileage deduction (at 55p/mile for the first 10,000 business miles) ready for your Self Assessment.
Not if you use HMRC's flat mileage rate. The 55p/25p rate is all-inclusive - it already covers fuel, insurance, road tax, servicing and wear and tear. What HMRC does want is a written log of each business journey, which is exactly what this tool produces. Keep parking, toll and congestion charges separately, though those are claimable on top of the mileage.
Any journey made wholly and exclusively for running your rental business: property inspections, meetings with contractors or maintenance crews, viewings with prospective tenants, picking up materials for repairs, trips to your accountant or solicitor on rental matters, and tribunal or court hearings. The wholly-and-exclusively test matters here - you can't combine a property trip with a personal errand (HMRC calls this "duality of purpose"), so popping to the supermarket on the way doesn't count. Check with an accountant on edge cases.
HMRC gives you two ways to claim vehicle costs. The flat mileage rate (55p, then 25p over 10,000 miles) bundles fuel, servicing, insurance and depreciation into one simple per-mile figure. Actual costs is the harder route - you work out the business-use proportion of every running cost and claim capital allowances on the vehicle separately. Most landlords choose the flat rate because it's far less paperwork. Important: if you've already claimed capital allowances on a vehicle, you can't use the flat rate for it — and once you start using the flat rate for a vehicle, you stick with it for as long as you own that vehicle.
We use OpenStreetMap routing, which takes the shortest driving route - Google usually picks the fastest route with live traffic, so the two can disagree in built-up areas (especially around big junctions or airports). For tax purposes HMRC wants the actual miles you drove, not a theoretical route; so if you went a different way, edit the miles for any journey directly in Step 2. The tool just saves you typing in routine routes from scratch.
HMRC lets you claim 55p per business mile for the first 10,000 miles a year — driving to inspections, contractor visits, supply runs and viewings. Most self-managing landlords cover 3,000–8,000 business miles a year, so that's £1,650–£4,400 in allowable expenses left on the table if you're not tracking them.
A flat-rate claim still needs proof. HMRC expects a log showing the date, route, purpose and miles for every business journey — kept for at least five years. This tool builds that log for you and prints it in the format HMRC expects, so you're covered if they ever open an enquiry.
