Lots of Sky customers may notice an extra charge on their accounts - unless they act quickly.
From November 29, any new Sky Glass or Sky Stream package customers will be charged an additional £5 per month if they skip ads when watching live television. The added cost will also affect customers who were given the add-on for free on either a 12 or 18 months contract - once that initial contract comes to an end.
The Sky Glass service was first launched in Autumn last year, meaning lots of customers who signed up at the start will have finished their contract or be coming to the end of their initial deals shortly. Sky Stream was launched earlier this year, meaning current contract holders will have a little longer until the charge potentially impacts them.
