Prisons: Heating

Asked by Nick TimothyConservativeMinistry of JusticeTabled Answered 30 June 2026UIN 11808

The question

To ask the Secretary of State for Justice, which prisons currently have underfloor heating in prisoner cells; and whether any under construction prison places will have underfloor heating in prisoner cells.

Answered by Sarah Sackman

Underfloor heating is cheaper to run and safer in prisons because it operates at lower temperatures than traditional radiators, reducing energy costs, working efficiently with low-carbon heat pumps, distributing heat more evenly to minimise heat loss, and eliminating exposed radiators that could be damaged, tampered with, or cause injury.

Underfloor heating is currently installed at the following HMPs,

  • Wetherby

  • Durham

  • Frankland

  • Cardiff

  • Nottingham

  • Stocken

  • High Down

  • Cookham Wood

  • Earlestoke

  • The Mount

  • Parkhurst

  • HMP Aylesbury

  • HMP Winchester

  • HMP Bullingdon

  • Five wells

  • Fosse way

  • Berwynn

  • Bronzefield

  • Peterborough-

  • Rye Hill

  • Millsike

  • Littlehey

  • Maidstone

  • Bure

  • Oakwood

  • Lewes

  • Elmley

  • Parc

All our new prisons will feature underfloor heating, as will all new houseblocks being built at existing prisons. Where appropriate, the refurbishment of existing prison wings may also include the installation of underfloor heating.
