We’re proud to offer the region’s longest and most comprehensive guarantee.

Setting the Standard

At double the industry standard, Trent Valley Windows’ 20 Year Guarantee offers complete value for money and, importantly for homeowners across Derbyshire and the East Midlands, decades of reassurance.

We offer such comprehensive protection because we have complete faith in our products. Everything that we install is designed and made to last, just like our commitment to you.

Our Guarantee

A Lifetime of Reassurance

We understand that windows, doors and living spaces are not an everyday purchases. They’re an investment in your home. As such, they need a guarantee to match.

If you need any help, advice or repairs during your guarantee period, please get in touch and a member of our team will be there to assist.

Installation Focus - Fitting

What’s Excluded

There are some restrictions to your guarantee. For example, as standard, environmental damage isn’t covered. It’s also important that you keep your product in a good state of repair. Similarly, if a third party conducts any modifications, then that will invalidate the warranty.


Trent Valley Windows is a trusted name for home improvements, and we can be relied upon to fulfil the various promises we make to every customer.


Anyone you speak to at Trent Valley Windows will be open and honest so that you know exactly what to expect. Our pricing structure is also transparent and fair as we believe in offering nothing but fantastic value.


To have been involved in the industry as long as we have, you have to be consistently good as what you do and keep your prices competitive. The product quality that we’re so synonymous for is partly due to the computer-controlled equipment we use.

20 Year Guarantee

Trent Valley Windows is one of the only home improvement companies to give its customers a 20-year guarantee with almost every product. It covers all moving and non-moving parts. The guarantee is testament to our manufacturing and installation skills.

Many customers are compelled to choose Trent Valley Windows because of the affordability of our products. It’s a rare thing, but if you ever find similar quality products for less elsewhere, let us know and we’ll enforce our price promise for you.
