Guarantee Authorisation Process

Project sign off by our Technical team is required on all projects as part of the process to authorise the appropriate system guarantee. Sign off is provided either by site audit and inspection from our Technical Services Managers on specification and major projects, or by site certification directly by the Approved Contractor. The process will be agreed at the outset of the project.
