Mast Audit Results
The last comprehensive audit of mobile masts across the Channel Islands was conducted in 2017. This audit examined all 274 mast sites and confirmed they were well within the ICNIRP health and safety limits.
Since the, we have periodically commissioned additional independent audits that focus on new and upgraded masts, as well as masts in Alderney and Sark. The most recent audit was completed in September 2024 with a focus on new and upgraded masts and a sample of existing sites.
