Professional Trailer Servicing You Can Trust
As an NTTA Trusted Workshop based in Daventry, we follow recognised industry standards and manufacturer guidance when carrying out servicing and maintenance.
Our workshop is fully equipped to handle routine servicing, safety inspections and preventative maintenance across most trailer types. Whether your trailer is used commercially or privately, we help you minimise downtime and avoid unexpected breakdowns.
Regular servicing is essential to ensure your trailer remains safe, reliable, and compliant with road safety regulations. Our expert servicing keeps your trailer in peak condition – reducing downtime, extending its lifespan, and helping you avoid getting a PG9 notice.

What’s Included in a Trailer Service?
Every trailer is different, but a standard service typically includes:
- Inspection of braking systems and brake adjustment (cables, shoes, drums)
- Tyre condition and pressure checks (tread depth, wear patterns, and pressure)
- Wheel bearing checks (and adjustment or replacement if required)
- Suspension and axle inspection
- Electrical system and lighting checks
- Coupling head and overrun device inspection
- Chassis and structural inspection
- General safety and roadworthiness assessment
If we identify any issues, we will explain the findings clearly and discuss recommended repairs before proceeding.
How Often Should You Service a Trailer?
The National Trailer and Towing Association (NTTA) recommends servicing every:
- 6,000 miles or every 6 months — whichever comes first
- 3,000 miles or every 3 months for intensive commercial use
General Guidelines:
- Leisure trailers (e.g. camping or caravan): Every 12 months or 6,000 miles
- Commercial/industrial trailers: Every 6 months—or more often for heavy use
- Boat trailers: Every 3 months or 3,000 miles due to water exposure


Why Regular Trailer Servicing Matters
Your trailer works hard – often carrying heavy loads and operating in challenging conditions. Over time, wear and tear can compromise braking efficiency, tyre integrity and structural safety.
Regular servicing helps to:
- Safety – Ensure that brakes, bearings, tyres, and other critical components are working correctly – reducing the risk of accidents or breakdowns.
- Longevity – Routine maintenance extends the lifespan of your trailer, components, and tyres – protecting your investment.
- Cost-Effectiveness – Catching small issues early helps avoid expensive repairs or roadside failures.
- Roadworthiness – A well-maintained trailer stays legal and compliant, helping you avoid fines or penalties.
Preventative maintenance is always more cost‑effective than emergency repair.
Stay Road‑Legal and Avoid Costly Defects
Many common trailer faults – including worn brakes, damaged tyres and lighting issues – can lead to dangerous situations or even a PG9 prohibition notice.
Routine trailer servicing significantly reduces the risk of enforcement issues and ensures your trailer remains compliant with UK road safety standards.
If your trailer is used for commercial purposes, regular maintenance is even more important to protect your business and reputation.

Special Considerations
- Boat trailers: Bearings, hubs, and brakes need extra attention due to water exposure
- Heavy-duty use: Construction or landscaping trailers may need more frequent servicing
- Manufacturer guidelines: Always follow specific maintenance intervals and recommendations
- Daily checks: A quick visual inspection before every use is always a smart move
Optional checks and repairs can also include winches, ramps, tilt-bed functions, and tie-down systems.
