Clear answers. Informed decisions. No guesswork.
Diagnostics from £85 (workshop) / £140 on site
Modern plant and machinery faults are often electrical or electronic in nature, and visual checks alone are no longer enough to identify the faults.
We diagnose the cause, then quote the repair — no guesswork, no parts fitted without approval.
We use Jaltest professional diagnostics testers to accurately identify faults, allowing you to understand what's wrong before committing to repairs.
Our diagnostic-first approach saves time, reduces downtime, and prevents unnecessary parts being fitted.
Plant and Machinery diagnostics
Our Approach
Diagnostics are offered as a stand-alone service to ensure faults are correctly identified before repairs are discussed.
Diagnostic charges apply regardless of repair outcome.
On-site diagnostic call-outs
- Electrical faults.
- warning lights.
- intermittent issues.
- Derate / limp mode problems.
- Breakdowns.
No-start / no-crank investigations
- Power supply issues.
- immobiliser faults and ECU communication problems.
Electronic health checks
- Preventative diagnostics to reduce unexpected downtime.
- Historical fault checks.
- Targeted diagnostics for electrical power, charging and ECU supply faults that commonly cause no-start and intermittent issues.
Fleet / Site Diagnostic Health Checks
- Preventative diagnostics for fleets and multiple machines, helping identify developing faults before downtime occurs.
How our Diagnostic service works
- Initial diagnostic assessment - We carry out a full system scan, review fault codes and check live data relevant to the issue.
- Clear explanation of findings - You'll be informed of what we've found, likely causes, and recommended next steps — in plain English!
- Repair options - If repairs are needed, we'll provide a clear quote before any further work begins. No work is carried out without approval.

Repairs & warranty
Repairs are only carried out following diagnosis and customer authorisation.
Parts supplied and fitted by us are covered by a 90-day warranty, unless otherwise stated.
Warranty does not cover:
- Pre-existing or unrelated faults.
- Further issues arising from wear, corrosion, wiring damage or water ingress.
- Faults caused by previous repairs or third-party modifications.
Diagnostic findings reflect the condition of the machine at the time of inspection. Some faults may be intermittent or develop after testing.
