Technical Audit

Every property benefiting from a Protek Warranty undergoes a rigorous technical audit process. A site based  inspection will be carried out to ensure the property meets the standards required for provision of a Protek warranty. The process covers design, materials, component specification, and workmanship. 

The bespoke technical audit is carried out by one of our surveyors from a national network spanning the whole of the UK. The process is administered electronically with each stage reported quickly. This allows the status of each inspection or the rectification of defects identified during the course of construction to be communicated to stakeholders as quickly as possible.

Once instructed, our site audit surveyor will make contact with you to identify the proposed schedule and request the relevant information to carry out a design and calculation check.

Each design and calculation check has to be approved or issues identified remedied prior to relevant works starting on site.
