Repairs, Returns and Wiring

Due to the extremely high workload in our workshop, returns, repairs, looms, harnesses and adaptors may take 6 to 8 weeks to be completed.
We will endeavour to improve on this time, but we cannot promise any quicker turnaround.

Returning Items for Repair or Exchange.

Open Monday to Thursday 09:00 - 17:00
