Broadband supplier Zen Internet has been selected as the best internet service provider (ISP) in a customer satisfaction survey conducted by Which? magazine.

According to the Telegraph, the consumer magazine has ranked Zen at the top of the list for customer service in each of the past four years.

The broadband provider was given a score of five out of five for speed and reliability as well as for customer service.

It also achieved three out of five in terms of value for money, despite being relatively expensive compared to other broadband deals, the newspaper noted.

The results will be encouraging for some providers, with O2, Utility Warehouse and Be Broadband all scoring more than eighty per cent on average.

However, the UK's biggest ISPs - BT, TalkTalk, Virgin Media and Tiscali - fell short of the 60 per cent mark.

The Telegraph cited the report as saying: "For most Which? members, Zen's 'marvellous customer support', reliable connection and willingness to go 'the extra mile' to resolve problems are worth paying more for."

Zen was also praised for offering customers one-month contracts instead of tying them into longer deals.

Launched in the UK in 1995, the ISP has received a number of awards over recent years, including North West Business of the Year.
