An extended warranty is an easy way to protect your purchase, against any manufacturing defects causing breakdown. You will benefit from free repairs for the term of the warranty period & If your equipment can't be repaired then we will replace it free of charge.(A delivery surcharge may apply for non UK mainland addresses)
This warranty and the standard manufacturer’s warranty does not cover general wear and tear, abuse or misuse or incorrect installation.
