Frequently asked questions

What does a PBX contract usually cover?
PBX contracts take three broad shapes. 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.
Where are PBX contracts advertised?
Stotles brings together PBX tenders and contracts from 100+ portals into one search, so you do not have to check each portal separately, and you can set alerts for new opportunities across the UK and Ireland.
If you want to search the government portals directly, Find a Tender carries higher-value contracts across the UK and Contracts Finder carries lower-value contracts in England. Public Contracts Scotland, Sell2Wales and eTendersNI cover Scotland, Wales and Northern Ireland, Ireland's eTenders covers Irish public bodies, and many councils, NHS bodies and housing associations publish on their own e-tendering portals such as ProContract. PBX replacements often arrive as lots inside wider telephony and unified communications frameworks, and support contracts are usually tied to the make of the installed exchange.
What do you need to bid for PBX contracts?
Telephony suppliers must meet Ofcom rules on emergency call access, and call recording must handle data in line with UK data protection law. Tenders usually set minimum insurance cover, check financial standing and ask for evidence of similar contracts at selection stage. Under the Procurement Act 2023, suppliers can be excluded for certain criminal convictions, insolvency or failure to pay tax.
How is PBX work bought, and who buys it?
Support contracts are often tied to the make of the installed exchange, and replacements frequently arrive as lots inside wider telephony and unified communications frameworks. Councils, universities, police and fire and rescue services, NHS bodies and central government departments all tender for PBX.
How do I find PBX contracts before they are formally tendered?
Read digital and technology strategies, licence and contract renewal dates, architecture reviews and early market engagement notices, which show PBX work coming due ahead of a notice. On Stotles you can track those signals and the buyers behind them, then follow a notice from pre-tender through to award.
What CPV codes cover PBX procurement?
PBX notices carry 32540000 (Switchboards), 32524000 (Telecommunications system) and 50330000 (Maintenance services of telecommunications equipment).
