Our specialists worked with Serco's Facility Management Team to develop bespoke Dudley Resan WC backplates, basins and basin brackets. The solution delivered has proven to be exceptionally hard-wearing whilst saving both time and money.

HMP & YOI Doncaster cells were previously fitted with Armitage Shanks Portland WC pans and ceramic basins plus Mazak basin brackets. Despite the brackets being tested to 150Kg and breaking at around 200Kg, they were coupled with the expectedly fragile ceramic basins and were unable to withstand the heavy treatment to which they were being exposed. The decision was therefore taken to replace Portland WC pans with Resan models. The prison walls are robustly constructed from concrete so any replacement products needed to be easily retrofittable. In addition, when ceramic sanitaryware shatters, the resulting fragments are extremely sharp and present an obvious and significant security risk. Under the terms of the management contract, Serco loses revenue of around £300 for every night that a cell is left out of service whilst broken sanitaryware is being replaced.

Our team began by talking to Serco about the breakages and the resulting operational problems. Site visits were also completed as part of the process in order to better understand the project requirements. The first problem to be addressed was the weakness of the basins and support brackets. Serco confirmed that the previously specified Portland basin had been discontinued by Armitage Shanks.

In order to provide a solution, TYDE’s design team exploited state-of-the-art CAD/CAM and rapid prototyping capabilities to configure an alternative. Moulds were then produced along with a sample basin for approval. The Thomas Dudley Group includes an award-winning engineering foundry. Here, the team set about developing a new bracket to support the newly designed basin. Engineered using an exceptionally strong grade of ductile iron, this provided far greater durability than the old Mazak bracket. Whilst a WC pan from the existing Resan range provided a compatible replacement for the Portland ceramic pans, a bespoke stainless steel backplate was needed in order to comply with the installation requirements approved by Serco. Bespoke anti-swivel taps completed the package.

The partnership with TYDE and the bespoke products that have been developed have enabled Serco to realise significant benefits:

  • 90% reduction in the number of basins and brackets broken
  • 95% reduction in the number of WC pans broken
  • 40% reduction in typical replacement sanitaryware installation time
  • 90% reduction in revenue lost due to cell downtime
  • Convenience of being able to order WC pans, basins, brackets and other products from a single source of supply
  • Security of and responsiveness of supply via TYDE’s customer-driven stock agreements which provide the reassurance of knowing that a guaranteed, predetermined stock level will be maintained for every specified product

The future

Serco are actively evaluating ways in which the partnership with TYDE can be extended. TYDE's market-leading concealed cisterns range which are compatible with Resan WC pans are being considered along with the potential to provide solutions across other Serco controlled institutions.


“We have developed a trusted partnership with the team at TYDE, one that has helped us achieve the goal of reducing lost revenue whilst providing a robust alternative to typical sanitaryware that proved costly to replace”
