Several UK telecoms and Internet Service Providers (ISP) have been listed in this year's Telegraph 1000, which bills itself as a list of "Britain's Brightest Businesses" (i.e. the fastest growing companies and partnerships with sales of between £5m and £500m).

The table is based on research work by innovation agency NESTA and verified by business information specialist Dun & Bradstreet (D&B). In total it represents companies that stand out and have together generated over £50 billion in sales. We were pleased to find that quite a few telecoms and internet providers had been listed.
