There are two main costs:

• the broadband DSL home access costs from a service provider ~ £20-30 per month
• the equipment costs (typically starting with a basic single user modem up to a multi-port router to connect your home to the service ~ £70-150

Wireless systems have a slightly higher unit costs but have the benefit of not requiring cabling throughout the house.

If you do not wish to install yourself then additional costs must be added.
