Fleet maintenance records: what to keep and for how long

By the Smart Strix team · Updated 15 July 2026

The maintenance file is what stands between an operator and a difficult conversation with DVSA — here is what belongs in it and how long each piece stays.

In short: DVSA guidance says maintenance records — safety inspection reports, driver defect reports, rectification evidence and maintenance planning — should be kept for at least 15 months, in paper or electronic form, and be retrievable on request. Safety inspections happen at planned intervals you declare and justify, not a fixed statutory frequency. This explainer is from Smart Strix, the UK-first fleet platform for 2–50 vehicle fleets; the definitive text is DVSA's Guide to Maintaining Roadworthiness, so review the current edition alongside this page.

Which maintenance records should a fleet keep?

The maintenance file DVSA expects an operator to produce breaks into six categories:

Record	What it shows
Safety inspection reports	Scheduled examinations by a competent person, with items checked and results
Driver defect reports	Daily check findings and mid-shift faults, with the assessment made
Rectification evidence	Job sheets, invoices or workshop entries proving each fault was fixed
Maintenance planner	A forward wall-chart or digital schedule of inspection dates for every vehicle
Annual test and prohibition history	MOT/annual test outcomes and any DVSA encounters, plus what changed afterwards
Statutory documents	V5C, insurance, plating certificates, tail lift/LOLER examination records where applicable

For a van fleet outside O-licensing the legal pressure is lighter, but the same file — trimmed to suit — is what demonstrates duty-of-care compliance after an incident, and it is what accreditation schemes ask to see.

How long must maintenance records be kept?

The headline figure, attributed to DVSA's Guide to Maintaining Roadworthiness, is 15 months for safety inspection records, driver defect reports and associated rectification evidence. The window exists so DVSA can examine a meaningful rolling period of your systems during an investigation, a fleet visit or a public inquiry. Points worth noting:

The 15 months runs from the date of each record, so the file is continuously pruned and refilled — nothing in the window may be missing.
Records must follow the vehicle's story even if it changes registration or leaves the fleet mid-window; keep files for disposed vehicles until their retention expires.
Many operators keep records for two years or more voluntarily, because trend data supports warranty claims, resale values and accreditation audits.
Other regimes overlap: tachograph data, working time records and accident documentation each have their own retention rules — check the current gov.uk pages for each.

How often should safety inspections happen?

There is no single statutory interval. Under DVSA guidance, the operator sets safety inspection frequency based on vehicle age, mileage, load types and operating conditions, then declares it (O-licence holders state it on the licence) and sticks to it. Common practice ranges from 4 to 13 weeks, with harder-worked and older vehicles inspected more often; intervals are normally expressed in ISO weeks so the planner never drifts. Two disciplines matter more than the number chosen: inspections must happen on time — an examiner will lay the planner against the actual reports and count the gaps — and the interval should be revisited when evidence (defect rates, annual test results) suggests it is too generous. The daily walkaround check, covered in our printable checklist guide, runs alongside inspections and never replaces them.

Are digital maintenance records accepted?

Yes. DVSA accepts electronic record-keeping on equal terms with paper, and its guidance acknowledges digital systems explicitly. The tests are the same whichever medium you use:

Complete — every inspection, defect and repair in the window is present
Attributable — each entry identifies who made it and when
Tamper-evident — records cannot be silently altered after the fact
Retrievable — you can produce any vehicle's file quickly at a visit or inquiry

Digital's practical advantages are timestamps, photographs attached at source, and the end of the missing-page problem; the weighing of the two approaches gets a full treatment in paper vs app vehicle checks. Hybrid systems are fine too — a paper inspection sheet scanned into a digital file counts, provided the scan is legible and filed promptly.

Smart Strix gives each vehicle a single organised file: maintenance history, inspection due dates, fuel logs, check photos, and MOT, insurance and V5C expiry alerts before documents lapse. See maintenance features — the rules above come from DVSA, and Smart Strix is where the evidence lives.

Who inspects maintenance records, and when?

Several audiences, with different triggers. DVSA examiners review records at desk-based assessments, operating-centre visits and after poor roadside encounters; Traffic Commissioners see them at public inquiry; insurers request them after serious claims; and accreditation auditors — FORS being the common one for van and mixed fleets — sample them annually. A weak paper trail also shows up indirectly through prohibitions and test failures in your OCRS score. The operators who sail through all of these are rarely the ones with the most elaborate systems — they are the ones whose records are simply complete, current and findable.

What are the most common record-keeping failures?

The recurring findings at DVSA visits: inspection intervals stretched beyond the declared frequency; defect reports with no rectification trail; brake performance not assessed at inspections; the maintenance planner abandoned months ago; and records for off-fleet vehicles binned early. Every one is a systems failure rather than a mechanical one — and each is cheap to prevent with a calendar, a named owner for the file and ten minutes of weekly housekeeping.

Frequently asked questions

How long do fleet maintenance records need to be kept in the UK?

At least 15 months for safety inspection reports, driver defect reports and rectification evidence, per DVSA's Guide to Maintaining Roadworthiness. Some overlapping regimes — tachograph data, working time, accident records — carry their own periods, so check current guidance for each.

Is there a legal safety inspection interval for commercial vehicles?

No fixed statutory interval exists. Operators set and declare a frequency justified by vehicle age, mileage and usage — commonly between 4 and 13 weeks — and DVSA expects the programme to be followed exactly and reviewed against evidence.

Do maintenance records have to be kept on paper?

No. DVSA accepts electronic records on the same terms as paper, provided they are complete, attributable, tamper-evident and quickly retrievable. Scanned paper documents in a digital file are also acceptable if legible.

Do I keep records for a vehicle I have sold?

Yes — retention attaches to the record, not the vehicle's presence on your fleet. Keep the file until each record's 15 months has elapsed, since DVSA can still examine the period when you operated it.

Do van fleets without an O-licence have to keep maintenance records?

There is no equivalent statutory retention rule, but records are the practical evidence of the employer duty of care under health and safety law, and insurers and accreditation schemes expect them. Mirroring the 15-month practice is a sensible default.

What does DVSA look for when reviewing a maintenance file?

Inspections happening at the declared interval with no gaps, defects traced through to recorded repairs, brake performance assessed, a live forward planner, and consistency between the file and roadside history. Gaps and dead ends are the red flags.

Does MOT history replace maintenance records?

No. The annual test is a single-day snapshot; DVSA's expectation is continuous evidence of planned inspections and defect management between tests. A clean MOT does not offset a missing maintenance file.
