Self-build warranties and insurance to protect your site
We always recommend purchasing your warranty at an early stage in the build process. Ideally, a couple of weeks before you start on-site so that the inspectors can audit the design drawings prior to the build going live on site.
If we are arranging the building control too, we will need to serve an Initial Notice on the local authority so that inspections can be sorted. Do note, however, that a structural warranty can be provided retrospectively (even once the build is complete), but the further into the build you are, the more expensive a warranty becomes.
