All our factory refurbished stock is tested in the manufacturer's workshops and comes with a manufacturer-approved 6 months warranty, offering additional protection beyond your statutory rights.

However, these warranties do not replace your rights under UK consumer law, and you can still seek remedies through us as outlined above.
