What is a Business Leased Line?

Leased lines are a premium form of 
Business Broadband. The term 'leased' describes how you rent internet access from the ISP (Internet service provider). Leased lines are also referred to as dedicated internet access (DIA). This is because of the "always on" internet connectivity, 100% uptime guarantees and 24/7 support.

A dedicated line provides your business with a dedicated fibre connection between your premises and the local exchange. Unlike standard Business Broadband, a Leased Line isn't shared with neighbouring homes and businesses.

With a dedicated line, you won't struggle with slow connections at peak times. Your business will receive the fastest speeds available with no drop-in service, with a fixed bandwidth which provides identical upload and download speeds. This is ideal for businesses that upload large files to the cloud.

If your business increasingly relies on cloud services and internet access and your current internet service isn't fast or reliable enough, then a dedicated leased line could be right for your business. If you're still unsure, then read through the features of the top 10 leased line providers listed below and see if you can find the right solution for your business.
