There are so many factors that can affect home broadband speeds, the "up to" figures providers like to throw around are tantamount to guesswork. UK telecoms regulator Ofcom isn't a great fan of inaccurate claims, so it's forcing ISPs to change how they communicate speeds to potential customers. Companies have a whole year -- until March 1st, 2019 -- to prepare for the new rules. When they come into force, though, ISPs will be required to provide realistic speeds a customer can expect at their specific address at peak times, as well as a guaranteed minimum speed. What's more, if speeds drop below that minimum, companies have 30 days to rectify the shortfall or customers can walk away from their contracts without incurring early exit penalties.
