The works will replace identified obsolete and ageing components with compatible equipment while retaining the existing cabling. The aim is to improve reliability, resilience and maintainability in the affected areas, including the house blocks and reception. This is electrical installation work, to be carried out at HMP Low Moss in Glasgow. The requirement is an upgrade to an existing system rather than a complete replacement. This procurement is at the planning stage: the Scottish Prison Service has stated an intention to award a contract, but there is no invitation to tender yet. It expects to publish a contract notice on 4 November 2026, followed by a request for quotation. The single lot will be evaluated by the Service against the requirements in that quotation. No procurement procedure or method, estimated value, budget, contract duration or award criteria are set out at this stage. The stated process therefore gives prospective suppliers an indication of the planned sequence, but the quotation will establish the detailed requirements and evaluation basis. The work is likely to suit electrical contractors and specialist security or communications-system integrators experienced in upgrading cell-call or comparable installed systems in secure facilities. Suppliers should be prepared to identify and replace ageing hardware, integrate compatible replacement equipment with existing infrastructure, and work around cabling that is to remain in place. Experience delivering reliably in operational prison settings would be relevant to the requirement across house blocks and reception. The buyer’s stated priorities—system reliability, resilience and maintainability—indicate that suppliers should be ready to explain how their proposed equipment and installation approach will support these outcomes. The quotation is expected to provide the basis for responses and evaluation, so interested firms can prepare relevant project experience and a technically compatible upgrade approach. ## Notice The works comprise the partial upgrade of the existing Cell Call System within HMP Low Moss. The purpose of the project is to replace identified obsolete and ageing system components with new compatible equipment, whilst retaining the existing cabling infrastructure. The upgrade shall improve system reliability, resilience and maintainability across the affected areas, which include both House Blocks and Reception. ### Lot Information Lot 1 The SPS has commenced this procurement process in good faith and with the intention of awarding a contract. Following publication of the Contract Notice, a Request For Quotation (RFQ) will be published by SPS and will be made available to bidders.
