It depends. We do offer a site visit service (subject to location) and do not charge a callout fee. Sometimes the repair is simple and can be done on-site. However, sometimes it is more complex or requires specialist equipment. In these cases we would take the unit to our workshop for repair and can return it to you when complete. It is also often much cheaper for the repair to be completed in our workshop as you are not paying for the engineers time on site. We offer both options so you can choose to suit your requiements.
