PBX Tenders
See open PBX tenders and awarded contracts for the UK public sector.
PBX and PABX procurement covers exchange hardware, hosted and IP PBX migrations, handset estates and the support contracts that keep an ageing switch running. Stotles tracks 249 matching notices: 130 awarded, 14 at pre-tender.
Buyers title this work in two vocabularies. Newer notices say PBX, older maintenance renewals say PABX, and barely any notice uses both, so a filter built on one term misses most of the other. Awards and renewals are most of the record here, which makes contract expiry dates the more useful signal.

Frequently asked questions
Frequently asked questions about pbx, pabx in the UK public sector.
How do I find PBX tenders in the UK?
Two routes. Watch the portals for new PBX and PABX notices as they publish, or move earlier and track the buyers whose exchange maintenance contracts are close to expiry. Stotles aggregates 100+ portals into one search, and platform-wide 2,198 notices are open right now. Filter down to this topic, read the buyer's strategy and budget documents, then approach before the specification is written.
Why search for PABX as well as PBX?
Because buyers rarely use both terms in the same notice. Of the 249 notices on record for this topic, only a couple mention PBX and PABX together. PABX shows up in the older support and maintenance renewals, including a run of Irish university and health service contracts. PBX dominates the newer replacement and cloud migration notices. A filter carrying one term and not the other drops roughly half the market.
What CPV codes cover PBX procurement?
The closest are 32545000 (PABX systems) and 32544000 (PABX equipment). Wider support and hardware work carries 32550000 (Telephone equipment) and 50330000 (Maintenance services of telecommunications equipment). Those codes are reference only and are not applied as a filter on this page: the six PBX-related codes together return 80 of the 249 notices the keyword filter finds, because plenty of on-intent notices carry a neighbouring code or none at all.
Is there a steady flow of open PBX tenders?
No. Award and renewal notices dominate the record: 130 of the 249 matching notices are awarded and 14 sit at pre-tender. Open PBX tenders arrive in ones and twos rather than in a steady stream, so this is a topic to keep an alert on rather than one to check by hand. Platform-wide, 0 notices were added in the last seven days.
What does a PBX contract usually cover?
Three broad shapes appear in the notices on record. Replacement, where a legacy on-premise exchange is swapped for a hosted or cloud platform. Maintenance and support, often a multi-year contract tied to one vendor's switch. And equipment supply, handsets and line cards for an estate that is staying where it is. Framework call-offs for unified communications frequently carry PBX scope as a lot, so the framework notices repay reading in full.
