Demon has tweaked its broadband packages for both consumers and businesses in a bid to offer better download limits.

The ISP surveyed its business customers to find out what factors were most important when it came to internet access. The company discovered that rather than headline speeds, its customers instead wanted decent fair usage policies with high download limits, excellent customer and assured minimum speeds

In response, Demon has tweaked its broadband services to meet these needs. The ISP offers two broadband packages aimed at home users, Home and Home/Office, as well as a number of services for businesses.

Demon was bought by THUS in May 1998 and then subsequently acquired by Cable&Wireless Worldwide in 2008. As a result, it can offer both packages on either its own ADSL2+ lines with speeds of 'up to' 8Mbps or the exchanges Cable&Wireless unbundled from BT, that come with download speeds of 'up to' 20Mbps.

The unbundled exchanges currently cover 60 percent of businesses in the UK. However, it is expanding this to cover just under three quarters (73 percent).

The Home package, which is priced from £15.28 comes with a 50GB download limit, while those that take out the £18.21 per month Home Office service will have a 60GB download limit and a free static IP address.

"We want to remind everyone that Demon Broadband is the best at providing business internet services. In addition, our heritage in the ISP market and in-house technical and business expertise means we can consult our customers on the best broadband package to suit their needs," said Matt Cantwell, head of the ISP.

The company also said it will be launching a number of assured rate broadband packages in July that come with guaranteed download speeds, starting from 1Mbps. These are available to businesses with 20 users or more and are priced from around £70 per month.

Demon also revealed it is working with BT on a trial of a fibre network in Muswell Hill in London. While it didn't comment on whether it would offer a fibre broadband service in the future, Demon did say ISPs considering investing in a fibre network should be ensured a guaranteed return on their investment.

However, Cantwell said this shouldn't mean BT can lay a large fibre network and then charge other ISPs high prices to rent the infrastructure.

Cantwell also said Labour's proposed 'broadband tax', which would have seen Brits with a telephone line forking out a £6 per year levy, was not the best solution when it comes to funding the roll-out of a fibre network across the UK.
