Repair terms & conditions

We do not charge for initial inspection. In the spirit of trying to minimise electronics needlessly ending up in landfill, if you have a low cost item, say under £100, please get in touch and we will assess the case and if it can be fixed quickly and economically we will consider it on a case by case basis. An estimate will be provided if the total cost of the repair is likely to be high (for instance long labour time or unexpected component costs). If you wish to pre authorise a higher than £100 limit then please get in touch. Repair turn around time is variable particularly if we are busy but we will always update you. Repairs come with a 3-month warranty on parts replaced and labour rendered. Shipping – Customers are responsible for arranging shipping to & from us. We reserve the right to dispose of items not collected within three months of notification of completion. Why Fentronix

We have over 34 years experience in a number of major electronics industries.
