The modern remedy is the ‘insurance-backed guarantee'.
Insurance-Backed Guarantees work because the insurance company, not the window installer, takes responsibility for the guarantee in return for a one-off payment and so will honour it in the event the installer ceases to trade.
The guarantee, if you sell your home, is entirely transferable, which also offers you an added USP. Independent Network researched many IBGs before establishing their own, in order to make it the best possible guarantee available in today's market.
The problem with most other schemes are that when something goes wrong - the homeowner finds that it is so difficult to make a successful claim - the guarantee is practically useless. The Network VEKA's ten year insurance backed guarantee ensures this is not the case, and protects customers in the unlikely event that the installation company ceases to trade.
