Yes, many UK commercial van specialists accept customer-sourced engines for fitting only. However, EngineMarket recommends bundled supply & fit to ensure warranty validity and single-point accountability for commercial operators.

• Warranty may be voided if engine not supplied by fitter
• Supply & fit packages include coordination and single invoice

Used engines are low-mileage donor units with limited warranty. Reconditioned units have worn parts replaced after inspection. Rebuilt engines receive comprehensive overhaul with upgraded components addressing known G9U failure points.

• Used: Fastest availability, lowest cost, shortest warranty
• Reconditioned: Balanced cost/reliability, 3-6 month warranty typical
• Rebuilt: Comprehensive upgrade, 12-month unlimited warranty standard
• Rebuilt best value for commercial vans over £4k market value

Declaring a replacement engine to your insurer is required but rarely increases premiums if specifications match original. Rebuilt engines with like-for-like power output typically have no impact on commercial van insurance groups.

• Notify insurer of engine replacement to maintain policy validity
• Like-for-like power/spec usually no premium impact
• Upgrades (e.g., dCi 100 to 140) may require specialist commercial cover
• Keep warranty documentation for insurer records if requested

If repair quotes exceed £1,500, van downtime exceeds 3 days, or failure involves injectors/turbo/timing on a G9U over 80k miles, replacement often offers better long-term value for commercial operators.

• Get compression test and diagnostic report before deciding
• Compare repair cost vs rebuilt engine price including downtime
• Commercial revenue loss often makes replacement more economical
• EngineMarket's free diagnostic checklist helps evaluate options

Upgrading power output (e.g., dCi 100 to 140) requires ECU remapping, potential gearbox/clutch upgrades and may affect insurance. Most commercial operators prefer like-for-like replacement to maintain reliability and compliance.

• Power upgrades require specialist ECU calibration
• Check gearbox/clutch rating before increasing torque output
• Insurance declaration required; may affect commercial premiums
• Like-for-like rebuild preserves ULEZ/CAZ compliance status

You'll need your V5C logbook, current MOT certificate, and proof of ownership. EngineMarket suppliers provide warranty certificate and engine number documentation for DVLA updates on commercial vehicles.

• V5C required to verify vehicle ownership and variant
• Engine number recorded on warranty certificate for DVLA
• MOT certificate confirms emissions compliance status
• Keep all documentation for insurance and resale purposes
