"if your business is in an FTTC enabled area and you are located up to 500m from the cabinet you could receive broadband speeds of up to 300Mbps without installing fibre"

G.fast is a type of technology that increases the speed of broadband over copper.

What this means is if your business is in an FTTC enabled area and you are located up to 500m from the cabinet you could receive broadband speeds of up to 500Mbps without installing fibre.

G fast works by speeding up the copper link from the FTTC cabinet to your location. There's no requirement to dig fibre, so you can get a significant increase in speed cost effectively.

G Fast is available up to 300Mbps. To get the increased speed, you need to run an availability check on your existing broadband line. If G.fast is available, you can then place an order to apply G-fast to your line, and in a matter of a few days you'll be enabled and enjoying ultra-fast broadband.

Why Get G.Fast?

G.fast is a cost-effective way to increase your speed without having to make a costly investment in getting fibre to your business with FTTP or a leased line. The SLAs aren't as good as those you'll find with a leased line, but the costs are far less too. If you want more speed while maintaining the low overhead costs of business broadband G.fast is an excellent option for you to explore.

G.fast speeds range from 500Mbps to under 100Mbps. The determining factor is the distance from the Openreach cabinet.

G.fast can undoubtedly increase the speed of your ADSL or FTTC broadband by using a new type of VDSL technology. This might leave you asking how much faster will my speed improve? The simple answer to this question is: it's determined by the length of copper wire the G.fast is enabled over. In the graph, you can see how distance is a significant factor in the download speed you'll get from G.fast.


If you are within 100m of the distribution point and your copper line is <100m in length G.fast could deliver speeds of 500Mbps. Within 150m the speed estimate drops to 300Mbps. Within 200m the estimated download speed drops to 250Mbps. Within 300m speeds can be expected to be over 125Mbps. At 400m the g-fast speeds drop to 100Mbps.
