    People often book them together, but an MOT and a service do very different jobs.

    The MOT is a legal inspection of minimum safety and emissions standards. It doesn't involve replacing worn parts or changing fluids — it tells you whether the car is roadworthy on the day.

    A service is preventative maintenance: oil and filter changes, fluid top-ups, brake and tyre checks, and other items in your manufacturer's schedule.

    How often to service: a common rule is once a year or every 10,000–12,000 miles, whichever comes first — but always follow your handbook or dashboard reminder, as intervals vary by make and model.

    Interim, full or major?

    • Interim: a lighter check, useful if you do high mileage.
    • Full: the standard annual service.
    • Major / manufacturer: adds items due at set mileages (e.g. spark plugs, filters, sometimes cambelt).

    Booking both together can save a trip, and some garages discount the bundle. Ask for an itemised list of what the service includes so you can compare like for like.

    FAQ

    Does an MOT include a service?
    No. An MOT is an inspection only.
    Can I get an MOT and service on the same day?
    Yes, many garages offer both together.
    Does servicing at an independent garage affect my warranty?
    Generally not, as long as the work follows the manufacturer's schedule and uses suitable parts — keep your receipts.
