All power tools are subject to minimum warranty of 12 months, most offer an extended warranty when your tool is registered online.  Most manufacturers have approved service agents and in the first instance it may be quicker and easier to take the tool to them with your proof of purchase. Your warranty begins from your date of purchase. If you are not near a warranty agent then many of the manufacturers will collect the tool from you. Please find the links below for each manufacturer and their warranty policy and procedures. 

We recommend that where appropriate that you register for the 3 year warranty, this will give you peace of mind when purchasing your tool.  Please note that if the failure of the tool is down to miss use by the operator, or is repaired by non-approved agent then this invalidates the warranty. There is no loan tool service whilst your machine is in for repair and in the majority of cases the machine will be repaired and not replaced. If you are unsure then please do not hesitate to contact us and we will be happy to help.
