Standard warranty for LG products is 3 years.
If the installer has completed the 1 day LG Technical Training course, an extended 7 year warranty can be applied.
If you are interested in becoming an accredited installer, get in touch with our team for more information on courses. Courses cost £95 + VAT for the 1 day. If the installer then goes on to purchase an LG unit, they are then eligible for a refund of the cost of the course.
