Should the goods be claimed to be faulty, the company shall ask for batch numbers for trace-ability and investigate to establish if the product is not in specification.  In larger, more complicated applications sales and technical staff may arrange to visit, view and collect product to also help establish the problem.  The assistance of the customer will speed up the resolution and in any cases where the goods are agreed faulty, the cost of product and delivery will be reimbursed fully or fresh delivery made at no extra cost.  This is in accordance with the UK Government Online and Distance Selling Regulations.
