Cable firm Telewest is offering a self-install broadband service that works through a cable modem built into the TV set-top box.
The modem creates a connection between the set-top box and PC, and is suitable for either 512Kbps or 1Mbps broadband services.
The self-install package means that engineers do not have to visit and allows customers to switch to fast web access within 48 hours. The setup cost is £12.50, and the service then costs between £29 and £35 a month.
Telewest is also planning to trial a wireless self-installation pack in the near future.
The firm currently offers two engineer-installed broadband packages: the 512Kbps service costs £29.99 a month, but customers of other Telewest services pay only £25 a month.
Telewest's network connects nearly five million homes, and the company has 1.76 million households as customers.
