For a no-compromise specialist internet service for home and business users, Zen Internet fits the bill. Although far from the cheapest provider, the service level lives up to the cost.
In my experience, the best domestic-grade service provider, able to compete on price with the "free broadband" brigade but with impeccable customer service.
Home PC Backup
Nothing in computers is more important than a regular backup, and the only backup that survives a fire or a burgulary is an online backup. At £4.95 per month, for as much information as you want to back up, Home PC Backup provide a great value service.
