Every living space that we sell, including our conservatories, orangeries and home extensions, comes with a 10-year guarantee. We hope that this cover confirms to you that our living spaces are made to last and will provide a superb setting.


Investing in a living space or home extension is a big decision, one that will make a big difference to your home, so it’s important that you don’t cut corners or compromise on performance.

Not all home improvement companies offer a guarantee, and not all guarantees are backed up with an Insurance provider.  We’re able to offer a 20-year guarantee – backed by an insurance backed guarantee (IBG) – because our home extensions are designed, manufactured, and built to remain perfectly functional and completely fit for purpose for a lifetime. Our materials and components have been selected for their inherent durability and our manufacturing and building processes are second to none.

Giving our customers a fantastic guarantee is a very important part of our Environmental Policy. Making our living spaces last ensures that no customer ever needs to get future repairs done to theirs, which prevents harmful carbon emissions and any over consumption, putting the planet first.

Most people will only ever buy a home extension once in their lifetime and it demands a strong investment. With that in mind, it’s important that it comes with a quality guarantee, one that will pay for itself over time, thanks to the huge energy savings you will make.
