Frequently Asked Questions
- What is the maximum MOT fee DVSA allows?
- The DVSA maximum MOT fee for cars is £54.85 in 2025/26. This is a statutory maximum — garages cannot charge more. The retest fee (for a first retest at the same site) is capped at £28.20. Garages may charge less, but they may not exceed these figures.
- What grants are available for EV charger installation in 2026?
- The Electric Vehicle Homecharge Scheme (EVHS) provides £350 towards a home charger for eligible drivers. The Workplace Charging Scheme (WCS) offers £350 per socket (up to 40 sockets) for businesses. The Public ChargePoint Grant (PCG) supports installations in residential car parks. These grants are administered through OZEV (Office for Zero Emission Vehicles).
- Are Uber drivers self-employed in the UK?
- No. In the landmark 2021 Supreme Court case, Uber drivers were ruled to be workers (not self-employed), entitling them to the National Living Wage, holiday pay and pension auto-enrolment. This affects the effective commission and take-home calculation for PHV drivers on app-based platforms.
- What is a typical labour rate at a UK body shop in 2025/26?
- Body shop labour rates in the UK typically range from £50 to £120 per hour depending on location, equipment and whether the workshop is franchised or independent. Insurance work often attracts a lower agreed rate. The body shop labour rate calculator helps establish a floor rate that covers overheads and generates a target margin.
