Generally, we only have the power off for up to 3 hours on any one day - sometimes much less. We're able to do this by one - doing the health checks on electrics in preparation of the fuseboard upgrade, mitigating risks by fixing issues between the health check and the upgrade, but also we usually book these on different days, giving us loads of time to prepare for the big day.
We can sign off Fuse Box Upgrades! being NICEIC (Part P) Registered, we have direct access to building control so we can sign our work off, hassle free.
