Every day, people use service numbers to make phone calls to companies and organisations, contact directory enquiries or even to vote in TV shows. But the cost of calling these numbers – which start 08, 09 or 118 – used to be difficult to find out. That has now changed, under a new system that makes the cost of calling service numbers clear for everyone. It's called UK Calling, and it's the biggest change to telephone calls in over a decade. Clear call rates for everyone from Ofcom Calling.
