Scope: this guide covers Great Britain: England, Scotland and Wales. Northern Ireland has separate operator-licensing, testing and drivers’ hours guidance. Vehicle classification and exemptions can be fact-specific.
A plant-hire fleet includes more than the hired equipment. Vans, trucks, trailers and transport vehicles connect the depot to every delivery and collection. Managing them in a separate spreadsheet creates gaps between bookings, drivers, mileage, tests, maintenance and defect evidence.
Start with operator-licence status
A goods vehicle operator’s licence is usually required in Great Britain when a goods vehicle above 3.5 tonnes gross plated weight, or above 1,525 kg unladen if unplated, carries goods for hire or reward or in connection with a trade or business. Vehicle-and-trailer combinations need a separate weight assessment. International hire-or-reward operations have a lower threshold above 2.5 tonnes maximum laden weight.[1]
A limited domestic own-goods concession may apply where the motor vehicle is 3.5 tonnes or less and the trailer’s unladen weight is below 1,020 kg. That figure is not a general exemption from trailer roadworthiness, tachographs or drivers’ hours.
Operating without the required authority can lead to prosecution and DVSA detention or impounding. The Traffic Commissioner recovery process is not guaranteed, and an unrecovered vehicle can ultimately be disposed of.[2]
Which roadworthiness test applies?
“MOT or annual test” is not one regime. The correct test depends on vehicle type, fuel and design gross weight.
| Vehicle | Test route | Typical timing |
|---|---|---|
| Petrol, diesel or hybrid goods vehicle up to 3,000 kg design gross weight | MOT Class 4 | Normally first test by the third anniversary of registration, then annually |
| Petrol, diesel or hybrid goods vehicle over 3,000 kg and up to 3,500 kg design gross weight | MOT Class 7 | Normally first test by the third anniversary, then annually |
| Zero-emission goods vehicle from 3,501 kg to 4,250 kg design gross weight | MOT Class 7 | Check the current GOV.UK timing for the specific vehicle |
| Petrol, diesel or hybrid goods vehicle over 3,500 kg | DVSA HGV annual test | Normally first test 12 months after first registration, then annually |
GOV.UK publishes the MOT class bands and test timing.[3][4] Record the correct due date and evidence against the vehicle rather than storing one generic “MOT” field for the whole fleet.
Trailers need their own decision and record
It is incorrect to say that every trailer over 750 kg requires an annual test. DVSA’s annual-test categories include semi-trailers, equipment built or adapted to form part of an articulated vehicle, specified A-frame trailers and converter dollies, and certain trailers over 1,020 kg unladen with powered braking rather than standard overrun brakes. Horseboxes above 3,500 kg gross weight are also identified.[5]
Do not replace the 750 kg myth with a blanket statement that every trailer above another weight follows the same route. Check the specific trailer category and any exemption. A trailer outside the statutory annual-test categories must still be roadworthy, inspected, maintained and included in the defect process.
The trailer record should include its identifier, make, model, plated and unladen weights, braking system, coupling, test status where applicable, safety-inspection schedule, defects, repairs and allocation to the towing vehicle or delivery run.
Inspect acquired, hired and borrowed vehicles before first use
DVSA says first-use inspections are essential for vehicles and trailers newly brought into the fleet, including items leased, hired or borrowed. Obtain evidence that a safety inspection was completed within the relevant interval. If suitable evidence is unavailable, inspect before public-road use.[6]
A supplier’s pre-delivery or pre-rental record may provide useful evidence, but it does not transfer the operating business’s responsibility for roadworthiness. Record the first-use decision, evidence reviewed, defects and authorised release.
Daily walkaround checks and defects
A driver or responsible person should complete a meaningful walkaround check, preferably immediately before use. The check should cover the vehicle and attached trailer, including coupling, tyres, lights, wheel fixings, body, load security and relevant equipment. Drivers must report promptly any defects that could affect safe operation, and unroadworthy defects must be rectified before use.[6][7]
A digital record should identify the vehicle and trailer, driver, date and time, inspected items, defects and photographs where useful. It should preserve the repair and the person who declared the equipment roadworthy and ready to return to service.
Safety inspections and maintenance planning
Safety inspections should be pre-planned at the frequency recorded in the operator’s arrangements. DVSA advises using a scheduling system that identifies inspection dates at least six months ahead. The completed record should show the equipment, mileage where relevant, inspected items, defects, inspector, repair details and roadworthy release.[6]
A current MOT or annual test does not replace first-use controls, daily checks, scheduled safety inspections or defect rectification.
Keep the records for at least 15 months
| Record | Operational purpose | DVSA retention point |
|---|---|---|
| Driver defect report and rectification | Shows faults, action and return-to-service control | At least 15 months |
| Safety-inspection and repair record | Shows planned inspection, defects and repair outcome | At least 15 months, including vehicles or trailers later sold, disposed of or removed |
| First-use evidence | Shows how roadworthiness was established when equipment entered the fleet | Keep with the relevant maintenance history |
| Maintenance-provider agreement | Defines outsourced arrangements without transferring operator responsibility | Retain while relevant |
Electronic systems should provide complete, accessible records, a clear end-to-end audit trail and protection against later alteration.[6]
Check tachographs and drivers’ hours separately
Operator-licensing status does not decide tachograph status. Most goods vehicles or combinations above 3.5 tonnes maximum permissible weight used on public roads are within assimilated drivers’ hours rules unless a specific exemption or derogation applies. A journey partly on public road is not wholly off-road.[8]
A potentially relevant derogation covers a vehicle or combination not exceeding 7.5 tonnes that carries materials, equipment or machinery for the driver’s own work within 100 km of base, where driving is not the driver’s main activity and the carriage is not for hire or reward. Every condition must be met; it is not a blanket exemption for plant-hire deliveries.[9]
How Equipy supports vehicle operations
Equipy manages vans, trucks and trailers beside plant on one fleet view. It supports GPS or GNSS-derived location data, trips, mileage, delivery and collection activity, checks, defects, maintenance records, documents and expiry alerts. It provides the operational record and audit trail; the operator remains responsible for classification, licensing, testing, roadworthiness and drivers’ hours.
Frequently asked questions
Does a 3.5-tonne van towing plant need an operator’s licence?
Not automatically, but assess the combination, carriage, journey, weights and any exemption. The limited domestic own-goods concession only applies where the motor vehicle is 3.5 tonnes or less and the trailer is below 1,020 kg unladen.
Does every trailer over 750 kg need a yearly MOT?
No. 750 kg is not a universal annual-test threshold. Check the specific DVSA trailer category. Every trailer still needs to be roadworthy and included in maintenance controls.
Which MOT does our van need?
Combustion or hybrid goods vehicles up to 3,000 kg design gross weight are Class 4; those over 3,000 to 3,500 kg are Class 7. Zero-emission goods vehicles from 3,501 to 4,250 kg are also Class 7. Heavier combustion-engine goods vehicles enter HGV annual testing.
Must we inspect a hired or borrowed vehicle before use?
Yes, establish roadworthiness before public-road use. Obtain suitable recent safety-inspection evidence or inspect before use. The operating business remains responsible.
How long should defect and inspection records be kept?
DVSA guidance says completed safety-inspection, repair and written driver-defect records should be kept for at least 15 months, including records for trailers and disposed equipment.
Does a current MOT prove roadworthiness until the next test?
No. Continue first-use controls, daily walkarounds, planned safety inspections, defect reporting and prompt repairs.
