Can I claim mileage expenses if I use a borrowed car for deliveries?

Yes, you can claim the approved mileage rate using a borrowed car, provided you own the vehicle for capital allowance purposes.

Yes, you can claim the approved mileage rate for business miles driven in a car that does not belong to you. HMRC looks at whether you are doing the driving for your self-employed work, not whose name is on the logbook.

Cars and vans use 55p per mile for the first 10,000 business miles in the tax year, then 25p per mile after that. You must keep a clear log of every business trip, including the date, miles driven and delivery addresses, to prove the journeys were strictly for work.

If you use the flat mileage rate, you cannot claim separately for fuel, MOTs, repairs or servicing on the borrowed car, because the mileage rate covers all of those running costs.
