More than 4,000 prisoners have satellite television in their cells.
Justice Minister Maria Eagle said that while no inmates in public sector jails had access to satellite TV in their sleeping quarters, five prisons run by contractors in England and Wales do offer the luxury.
Serco-operated HMP Dovegate in Staffordshire and HMP Lowdham Grange in Nottingham, as well as the G4S-run HMP Altcourse in Liverpool, HMP Parc in South Wales and HMP Rye Hill in Warwickshire all provide access to a “limited number” of satellite channels in cells.
Ms Eagle said the number of prisoners enjoying the perk fluctuated according to behaviour but that it was around 4,070 on December 10.
She stressed: “In these establishments, satellite television in cell is generally only available to prisoners who are on the enhanced or standard level of the incentives and earned privileges scheme.”
Ms Eagle was responding to a written parliamentary question from Tory Philip Davies (Shipley).
There are just over 84,500 prisoners in England and Wales, meaning around one in 20 has satellite TV in their cells.
Mr Davies described the figures as “absolutely revolting”.
He added: “No end of my constituents would love to have Sky TV but they cannot afford it, so it is a bit galling for them - through their taxes - to be paying for prisoners to be watching it in their cells.
“This isn’t in communal areas, it is in their cells. It has got nothing to do with rehabilitation but is a prime example of how conditions in our prisons are far too cushy.”
All five jails house category B prisoners - the second highest classification - for inmates who do not need the strictest security conditions but for whom escape must be made very difficult.
