Repairs and maintenance costs for a vehicle used in your trade are deductible as day-to-day running costs: servicing, MOTs, tyres, oil changes, and repairs to keep the vehicle in working order. If the vehicle is used partly personally, only the business-use proportion is deductible.
If you use the flat mileage rate (AMAP), do not also claim repair costs separately. The mileage rate covers all running costs.
