Are 10-year guarantees on double glazing worth anything?

In many cases, the short answer is, “No”. This is simply because many UPVC window companies will not be around in another 10 years.!

They “phoenix”, which means they run up debts, go bust, buy back the assets from the receivers at a knock down price and then set up virtually the next day under a very similar name to the company they just wound up!

When you’re spending a lot of money on a big purchase like double glazed windows, it’s a good idea to do some research into the company you intend to do business with.

It will certainly help you to know that your money isn’t going to a firm on the verge of going bust. You can search for any limited company at Companies House and it only costs £2 to get useful information.

Is your 10-year guarantee worth anything, then?

YES! is part of Armstrong Industries Ltd, which has traded continuously since 1996, without changing names, so you can rest assured that the 10-year profile guarantee on our UPVC

is credible. However, if you want complete peace of mind, you can pay £30 per order to buy an insurance-backed guarantee, which covers your double glazed windows should we cease to trade. Our insurance guarantees are regulated by the Financial Services Authority (FSA), which is the independent watchdog that regulates financial services.
