Telecoms giant BT has lined up a deal to purchase the Brightview Group, which owns ISP Madasafish and provides broadband services for the supermarket Waitrose.

The group, which has around 62,000 customers in the UK, said it intends to sell to BT for around £15.8m subject to approval from its shareholders.

Although BT would not go into detail about any future plans, it said billing and customer services for Madasafish and Waitrose customers would currently remain as they are.

Ian Livingston, BT Retail's chief executive, said: “This acquisition will ensure that Brightview's customers can benefit from our market-leading services, resources and technology development as well as the excellent customer service they're already receiving."

Brightview staff were unavailble for comment when we called. However, price comparison site, Uswitch, warned that Madasafish and Waitrose broadband customer could see customer support levels slip. Both companies have been highly rated for service in the past.

Uswitch representative Chris Frost said: “It’s a well known fact that smaller ISP’s are better for their customer service, they do not have as many customers so can give each individual more time.There is just too much demand on bigger ISP’s.

“Until the integration between brightview and BT has been completed and comes into effect Madasafish and Waitrose customers will probably not see a great deal of change. He recommended that people keep a close eye on the way that they were treated and reviewed this when the time came up to change their contracts.
