Sky are set to increase their TV, mobile and broadband prices for many of their customers following an increase in prices to energy and shopping bills.
The average increase is said to be rising by around five per cent - or around £3.60 a month.
Customers who have been affected, according to Which?, should be contacted by Sky themselves by email or post by March 24.
The consumer comparison website said that their broadband deals such as Sky Broadband Essential will rise from £25 to £27.50 while Sky Broadband Superfast will rise from £28 to £30.50.
In addition, television packages such BT Sport will rise from £27 to £28, Sky Signature will rise from £26 to £27 and Sky HD will rise from £7 to £8.
As well as their broadband and television services, phone calls Talk rates (for UK landlines and mobiles) will increase from 20p per minute to 22p per minute.
The news comes as the company is also re-introducing EU roaming charges as part of Sky Mobile.
There will be a daily cap of £2 however customers visiting Ireland, the Isle of Man and the Channel Islands will be allowed to use their UK allowance at no extra cost.
Many people are now asking the question, 'can I leave my Sky contract if the price goes up?' and Which? have said the following:
"Ofcom rules state that if providers raise the price of their broadband, mobile phone or landline deals by a rate greater than inflation, they must then allow customers to leave their contract penalty-free."
However the total bill, despite the price increase, is below the current inflation rate.
They explain that any customers who are struggling should contact customer service to discuss options - and if you're out of your contract, you can switch your deal at any time.
They add: "If you’re happy with the service you get from Sky and you're out-of-contract, it's worth seeing these price rises as an opportunity to haggle. It might sound daunting to some, but, like most providers, Sky both expects and invites haggling.
"The process is as simple as getting in touch with your provider and asking what it can offer. While you have the best leverage if you’re out of contract or have the right to exit penalty-free, Sky may be willing to offer deals to other customers affected by prices rises, particularly if you subscribe to several services."
