Bringing maintenance in-house is a control decision: your own workshop, your own standards, your own schedule. But the operator licence does not let you make that decision cosmetically. The legal requirement sits in the licensing Act itself, and the Guide to Maintaining Roadworthiness spells out what it means - and DVSA and the traffic commissioners check that the reality matches.
For goods vehicle operators, section 13C(4) of the Goods Vehicles (Licensing of Operators) Act 1995 requires that there must be satisfactory facilities and arrangements for maintaining the vehicles used under the licence in a fit and serviceable condition. Passenger operators face the mirror-image duty: the traffic commissioner must be satisfied that there will be adequate facilities or arrangements for maintaining the vehicles in a fit and serviceable condition. ‘Facilities and arrangements’ is doing heavy lifting in both - the licence assumes you either have the physical means to maintain your vehicles properly or a properly contracted arrangement with someone who does.
The guide’s operational translation is equally direct: operators who undertake their own safety inspections must have the correct equipment and adequate facilities for the size of the fleet and types of vehicles operated. That sentence sets the test - not a workshop in the abstract, but capacity matched to this fleet and these vehicles.
The adequacy question answers itself against the work to be done. A safety inspection must cover at least the scope of the annual test - so the facility must make that scope possible. In concrete terms, the assessors’ expectations run to: covered workspace where an inspector can work under and around the vehicle in all weathers - an inspection done in the rain in an open yard is an inspection with things missed; safe under-vehicle access through a pit or lift; lighting good enough to actually see defects; the tooling for the fleet’s vehicle types; brake testing capability - a roller brake tester on site, or a documented arrangement to use one elsewhere, because the guide expects brake performance assessment, laden where appropriate, at every safety inspection; and headroom and access for the largest vehicle in the fleet, not the average one.
The ‘size of fleet’ clause bites as fleets grow. The workshop that served five vehicles cannot absorb fifteen without the inspection intervals stretching - and stretched intervals are how in-house operations drift into non-compliance while looking busy.
Adequate facilities include the human arrangements. Someone competent must carry out the inspections - trained on the vehicle types, working to the inspection scope, and empowered to ground a vehicle without a scheduler overruling them. The records infrastructure counts as well: inspection sheets, defect rectification records, the maintenance planner, the 15-month filing. A workshop with a beautiful pit and no paperwork system fails the standard as surely as one with neither, because the operator’s duty is to demonstrate the maintenance, not merely to perform it.
The case for in-house maintenance is real - control of quality, no queue at the contractor, defects fixed on your schedule. The case against is the fixed cost of adequacy: the building, the equipment, the brake tester, the trained people, and the management attention to keep it all at standard. The decision that fails is the middle path: a ‘workshop’ that services but cannot inspect, so safety inspections are notionally in-house but actually done at a standard the facility cannot support. That pattern - common in investigations - is worse than honest contracting, because it produces inspection records the evidence does not back.
Maintenance facilities are a licensing issue from day one: the application asks about them, variations can re-open the question, and a public inquiry will test them. An operator whose facilities were ‘satisfactory’ at grant but have decayed - the brake tester broken for a year, the covered bay now used for storage, the inspector who left and was never replaced - is an operator whose licence undertakings are quietly failing. The discipline is to audit your own facilities against the guide the way DVSA would: could we, this week, inspect our largest vehicle to annual-test scope, brake-test it laden, and produce the records? If the answer hesitates, the facilities do.
For many fleets the right answer is neither fully in-house nor fully contracted, but a deliberate split: routine servicing, walkaround rectification and running repairs in-house, with safety inspections and brake testing contracted to a provider whose facilities genuinely meet the standard - under a written contract, with the monitoring duty that entails. The split works when it is designed rather than drifted into: the scope of each side written down, the planner showing who does which inspection, and no ambiguity about where the annual-test-scope work happens. The version that fails is the accidental one - the yard does ‘most of it’ and nobody can say who last inspected what to which standard. Choose the model, write it down, and resource it; the licence requirement is satisfied by the arrangement that demonstrably works, not the one that merely exists.
