Fixed postcode: This file is based on a snap shot of data provided by the largest fixed broadband providers in the UK, at postcode level, for the period of June to July 2014. Due to variations in broadband performance over time, the file should not be regarded as a defintive and fixed view of the UK's fixed broadband infrastructure. However, the information provided in this file may be useful in identifying variations in broadband performance by postcode and the impact of superfast broadband on overall broadband performance. The file should be viewed in conjunction with the Infrastructure Report published by Ofcom in December 2014, which details how each of the metrics is defined.

Due to privacy concerns we have not presented the information in postcodes with less than four broadband connections. Where we have excluded the data for this reason, we have substituted the data with "<4" to denote this.
