Which vehicle and which test?
HGV MOT is also called the annual test. Great Britain guidance covers relevant heavy goods vehicles, articulated vehicles and trailers, with specific categories and exemptions. The towing vehicle’s certificate does not establish the trailer’s test status.
Check the current category against the vehicle’s weight, construction, use and fuel type; do not apply one weight threshold to every vehicle. Northern Ireland uses DVA testing arrangements: use the separate official guidance rather than assuming the GB booking process applies.
Check the due date before booking
HGVs usually need testing each year, with the first test normally 12 months after first registration. Trailers usually need their first test one year after first sale or supply. Confirm the actual due date, category and any exemption through the official records and guidance.
Plan the vehicle and trailer separately, allow time for repairs and avoid relying on a last-day appointment. Use GOV.UK’s HGV booking guidance to find the appropriate authorised testing facility (ATF) or DVSA arrangement.
A practical preparation timeline
- Ahead of booking: confirm identity, test type, due date and the facility’s requirements.
- Before the appointment: arrange competent inspection and repairs; gather registration, plating and previous test or defect records relevant to the vehicle. Confirm what the facility needs you to bring.
- Before travelling: check roadworthiness, cleanliness and safe access for inspection; follow the facility’s loading and presentation instructions.
- After the test: retain the result and arrange any required repairs, retest and schedule updates.
Fees, failure and retesting
There is no single price for every vehicle and appointment. Check current official test and retest fees and ask the facility about any separate service charge before booking.
If the vehicle fails, follow the result, defect classifications and current retest instructions. A booking or an unexpired certificate does not make an unsafe vehicle lawful to drive. Do not drive with dangerous defects; arrange safe repair or recovery and obtain qualified advice where needed.
Annual testing does not replace maintenance
Keep daily walkaround checks, defect reports, planned safety inspections, maintenance and records operating throughout the year. Use the DVSA roadworthiness guide and a competent maintenance provider to set arrangements suitable for the operation.
Review the next due date after the result, keep the vehicle and trailer records distinct, and make unresolved defects visible to the person deciding whether the vehicle can be used. This guide is not a technical inspection manual.
