Broadband speeds in RM4
Share of RM4 premises by the fastest download speed available, averaged across all 153 postcodes in the district.
Superfast broadband availability is 88.7%, considerably lower than typical for this region. Gigabit coverage reaches 81.1% of postcodes. Real-world speeds show 81.1% of connected premises enjoying 300 Mbps-plus downloads, with 7.7% in the 30-300 Mbps range. A notable 1.5% of postcodes fall below the USO floor, which warrants checking coverage for individual addresses before moving house. The presence of below-USO postcodes is unusual in this part of Essex and suggests some areas may have older copper networks that haven't been upgraded to modern standards. This district therefore presents more variation than nearby postcodes and requires careful verification before committing to a location.
