How to Set Up a Maintenance System for Your Fleet

How to Set Up a Maintenance System for Your Fleet

Introduction

If you're an Operator Licence holder in the UK — especially with a Restricted Licence — one of the most crucial undertakings you've agreed to is keeping your vehicles in a roadworthy condition at all times.

But how do you prove that your vehicles are properly maintained? That's where a robust maintenance system comes in.

Whether you operate one van or a small fleet of HGVs, your maintenance system is the backbone of your compliance — and it can mean the difference between keeping your licence or losing it at a public inquiry.

In this guide, we'll walk you through how to set up a compliant, practical and efficient maintenance system that satisfies both DVSA expectations and Traffic Commissioner standards — even if you don't employ a Transport Manager.

Why Maintenance Matters Under Your Licence

Maintenance is one of the core undertakings of every Operator Licence. Fail to maintain properly and you risk:

- Prohibitions and fines

- Vehicle off-road time and lost revenue

- Regulatory action from the Traffic Commissioner

- Loss of good repute — and in serious cases, loss of the licence

A proper system also protects your drivers, your customers and your reputation.

What Is a Vehicle Maintenance System?

A maintenance system is the complete set of routines, records and responsibilities that keep every vehicle roadworthy:

- Daily walkaround checks

- Defect reporting and repair

- Preventative Maintenance Inspections (PMIs) at the right intervals

- Accurate records retained for the required periods

- Clear responsibilities — who does what, and when

Key Components of a Compliant Maintenance System

1. Daily walkaround checks — completed by drivers before first use, recorded and defects reported immediately.

2. Defect reporting and rectification — a written (or digital) process that tracks every defect from report to repair sign-off.

3. PMI inspections — safety inspections at appropriate intervals.

4. A maintenance planner — a forward plan showing when each vehicle is next due.

5. Complete records — retained for at least 15 months for safety inspections and associated maintenance/repair records, per the DVSA Guide to Maintaining Roadworthiness.

6. Clear accountability — even without a Transport Manager, someone must own the system.

In-House Maintenance or a Contractor?

Restricted Licence holders don't have to run their own workshop — most use a garage or contractor. What matters is the arrangement:

- If outsourced: use a reputable provider, agree PMI intervals in writing, and make sure invoices and inspection reports come to YOU so you can file them.

- If in-house: follow the DVSA guide's standards for facilities, tools and staff competence.

- Either way: the licence holder keeps ultimate responsibility — outsourcing the work doesn't outsource the compliance duty.

Preventative Maintenance Inspections (PMIs)

PMI intervals should be appropriate to the vehicle's age, type and usage — typically every 6–13 weeks depending on those factors. Older vehicles or high-mileage operations often need shorter intervals.

Don't guess: agree intervals with your provider, review them annually, and never let a PMI slip past its due date.

Creating a Maintenance Planner

A simple planner is enough for most small fleets — one sheet or spreadsheet listing, for each vehicle:

- Registration and vehicle details

- Date of last PMI

- Date next PMI is due (or mileage trigger)

- Any intermediate checks needed

Plan forward: book workshop time ahead of the due date so vehicles don't run overdue while waiting for a slot. Review the planner weekly.

Sample schedule fields (a practical example for small fleets):

| Vehicle | Last PMI | Next PMI Due | Mileage Trigger | Notes |

| Vehicle A | 1 Oct 2026 | 1 Jan 2027 | 40,000 miles | — |

| Vehicle B | 15 Oct 2026 | 15 Jan 2027 | 25,000 miles | Book early Dec |

Daily Walkaround Checks & Defect Reporting

Daily checks are the first line of defence. Drivers should check brakes, lights, tyres, steering, mirrors, body and trailer condition, and anything else relevant to the vehicle — and record the result every day, defect or not.

Defects must be reported immediately and repaired before the vehicle is used where safety could be affected. Keep the full chain: report → assessment → repair → sign-off.

Maintenance Records

Keep for every vehicle:

- PMI inspection reports

- Repair invoices and parts records

- Daily check sheets (or digital equivalents)

- Defect reports and rectification records

Safety inspection and associated maintenance/repair records must be retained for at least 15 months (DVSA Guide to Maintaining Roadworthiness). Store them so any record can be produced quickly when DVSA or the Traffic Commissioner asks.

Digital tools can help — but there's no legal requirement to go digital. Use whatever system your team will actually maintain consistently.

Common Mistakes to Avoid

- Missing or late PMIs

- Walkaround checks not recorded daily

- Defects reported but not tracked through to repair

- Records kept at the garage instead of by the operator

- No planner, so PMIs are only discovered when they're overdue

- Assuming the maintenance provider handles "the compliance side"

Seven Steps to Set Up Your System

1. List every vehicle and its details

2. Agree PMI intervals with your provider (or set them in-house)

3. Build the maintenance planner

4. Set up daily walkaround check sheets

5. Create a defect reporting and repair process

6. Set up a records file (paper or digital) with the 15-month rule in mind

7. Review the whole system quarterly

Final Thoughts

A maintenance system doesn't need to be complicated — it needs to be complete, consistent and provable. Daily checks, on-time PMIs, tracked defects and retrievable records will satisfy DVSA and the Traffic Commissioner, and they'll keep your vehicles earning rather than off the road.

Set it up once, review it regularly, and it will quietly protect your licence for years.
