For the majority of our products we will use our own fully-trained installers. For some of our products, we will instruct carefully selected partners to carry out the installation on our behalf. In this case, they will be installing to our defined standard and will be instructed to follow the Everest code of practice. All the installers we use are fully accredited and experts in their field.
