## Summary

The Corporate Officer of the House of Commons bought maintenance services for the UK Parliament’s television annunciator and Division Bell systems. These systems support parliamentary operations; the buyer described them as unique and critical. The work covers maintenance of both the annunciators and Division Bell systems, including reactive maintenance. The service is communications-system maintenance. The buying organisation is the House of Commons, with the House of Lords also identified as a buyer in the process. The service is for Parliament in Westminster, London. The awarded requirement concerns ongoing support for the existing systems and their operation together, rather than a supply of new equipment.

The procurement is complete and was awarded to Chubb Fire and Security Limited trading as Chubb Systems. The award date was 2 October 2026. The contract period runs from 19 October 2026 to 18 October 2028. The award value is £2,097,500 excluding VAT (£2,517,000 including VAT). The buyer used a direct award to extend services from the existing supplier, relying on the risk that a supplier change would create incompatibility and disproportionate technical difficulties in operating or maintaining the systems. There is one lot. The contract includes an option for additional reactive maintenance beyond the amount already estimated, with variable spend. The award is active.

For suppliers assessing future work of this kind, the requirement shows the importance of proven expertise in maintaining the Parliament’s existing annunciator and Division Bell systems, including how the two systems operate together. The buyer’s stated rationale also indicates that continuity, compatibility and avoiding technical difficulties in operation and maintenance are central commercial considerations. Credible competitors would need to demonstrate detailed knowledge of the installed systems and the ability to sustain their operation, alongside effective relationships with any subcontractors essential to delivery. The scope includes both planned support and reactive maintenance, so suppliers would need the technical capability and operational capacity to respond to maintenance needs across both systems.

## Notice

Provision of Maintenance for the Annunciators and Division Bell Systems

### Procurement Information

This direct award concerns the extension of services supplied by the existing supplier to support two systems (Annunciators and Division Bells) which are unique and critical to UK Parliament. The supplier has extensive knowledge of these systems and how they operate together with ongoing relationships with key subcontractors who are essential to the operation and maintenance of the systems. Any change of supplier would cause a difference or incompatibility in the services provided which would result in disproportionate technical difficulties in the overall operation and maintenance of the systems. Therefore, under Schedule 5 para 7: (7) The public contract concerns the supply of goods, services or works by the existing supplier which are intended as an extension to, or partial replacement of, existing goods, services or works in circumstances where-- (a) a change in supplier would result in the contracting authority receiving goods, services or works that are different from, or incompatible with, the existing goods, services or works, and (b) the difference or incompatibility would result in disproportionate technical difficulties in operation or maintenance.
