For the first time in the UK, a complete anti-ligature radiator solution (Contour’s DeepClean Extra+) has been officially approved by the Ministry of Justice (MoJ) for use within its property estate, including safer cells.
This landmark approval represents a major step forward in prison heating design. The DeepClean Extra+ anti-ligature radiator and guard has been rigorously tested under the MoJ’s specification for fixed furniture in cells (STD/X/SPEC/063), setting a new benchmark for safety, durability, and hygiene in custodial environments.
(Approved up to a maximum size of 1200mm x 960mm x 260mm. Larger sizes can be manufactured but must be signed off at local level.)
Why This Approval Matters
Heating in custodial environments cannot be treated like standard building design. A prison cell radiator must deliver safe, effective heating while resisting tampering, preventing ligature risks, and supporting infection control.
The approval of the DeepClean Extra+ is significant because it shows compliance with the MoJ’s strictest standards for safer cells – environments where suicide prevention and self-harm reduction are paramount. Now, for the first time, architects, contractors, and consultants specifying prison cell heating can choose an anti-ligature radiator that has been independently tested and approved.
Designed for Prison Heating Challenges
The DeepClean Extra+ is purpose-built for custodial and detention settings. Every feature addresses a safety, durability, or hygiene risk:
- Sloping top design to deter climbing or concealment
- Anti-ligature IP3X compliant grilles to prevent insertion of objects
- 10mm radius corners to minimise injury risk
- Robust 2mm Zintec or Magnelis steel construction for strength and longevity
- Internal strengthening strut for added structural integrity
- Patented full-height access door for secure, easy cleaning and maintenance
- Contour Secure cam locks for controlled, anti-ligature access
- Additional Pin Torx security screws on the front, side, and top to deter tampering
- BioCote® anti-microbial protection to help reduce bacterial contamination
This isn’t just a guard, it’s a complete, integrated safer cell heating solution.
Tested for the Toughest Environments
The approval followed over 12 months of development, including continuous design refinements and sector consultation. The DeepClean Extra+ was subjected to the MoJ’s heavy-duty destruction testing, verifying its ability to withstand attempts at damage, misuse, or dismantling inside a prison cell.
The result is a radiator system proven to perform in one of the most challenging environments possible.
Beyond Prisons: Wider Applications
While this MoJ approval applies specifically to safer cells within the estate, the DeepClean Extra+ design is also highly suited to other high-risk environments, including:
- Young Offender Institutions (YOIs)
- Police custody suites
- 136 mental health assessment suites
- Immigration detention centres
- Pupil Referral Units (PRUs)
In each of these settings, the need for tamper-resistant, hygienic, and secure heating is just as critical.
A Step Forward in Safer Custodial Design
This MoJ approval is not just a milestone for Contour, it’s a breakthrough for the custodial sector. For the first time, specifiers can confidently select an anti-ligature radiator system that has passed the most stringent testing for safer cells.
By combining safety, hygiene, and durability, the DeepClean Extra+ sets a new standard for prison radiators and safer cell heating design.
