Broadband Speed Map
The map below shows the average broadband speed across the UK. The dark blue/black areas are those with the slowest average speed, light blue and green have an average connection speed and yellow and red shows the areas with the fastest average broadband speed.
You can interactively see the speeds local to your postcode from the ofcom website and also use the samknows website to see what equipment is based at your exchange by provider. Some providers such as talktalk have upgraded systems that are not available to BT customers or providers using the BT wholesale network.
