Why Public Sector Organisations Order Without a Credit Card
NHS Trusts, schools, and universities don't typically hand over a credit card to buy IT hardware. These organisations operate on budget-controlled procurement systems where every purchase must be authorised, tracked, and audited. Purchase orders (POs) are the standard, mandatory mechanism for public sector buying. They aren't a workaround or a favour from the supplier; they're how the system is designed to work.
NHS England mandates a valid PO number on every invoice. Invoices submitted without one are returned unpaid. That's not a guideline; it's an operational rule governing billions of pounds in spending.
To put the scale in context, UK gross public sector procurement spending reached £434 billion in 2024/25, with the health sector seeing the biggest year-on-year increase. This guide explains exactly how to order hardware via PO, step by step, so your procurement team can get what it needs without delays or rejected invoices.
What the Procurement Act 2023 Means for Hardware Buyers
The Procurement Act 2023 came into force on 24 February 2025, replacing older EU-derived procurement rules with a simpler, UK-focused framework. If you work in procurement for an NHS Trust, school, or university, this legislation now governs how you buy goods and services.
For routine hardware purchases, below-threshold orders (UPS units, networking switches, replacement batteries, or a batch of wireless access points) can be placed via a direct PO to a supplier and remain fully compliant. No formal tender is required. You identify the supplier, agree the price, raise a PO, and the goods ship.
The Act also introduced a new Central Digital Platform (CDP) that centralises procurement notices and contract management. This platform applies to larger, above-threshold contracts and does not affect routine direct PO purchases for everyday hardware needs.
One notable trend driven by the new legislation: direct public sector procurement spend with SMEs hit a six-year high of 21% (£45.2 billion) in 2025. In the education sector specifically, 33% of spend went to SMEs, the highest proportion of any tracked sector. The Act was designed to open supply chains to smaller, specialist suppliers, and it's working.
Hardwarexpress is exactly the kind of SME supplier this new landscape was built for. Trading since 2004, we hold large stock levels and already supply NHS organisations, schools, and universities on purchase orders with 30-day credit terms.
The NHS SBS Tech Devices Framework and When to Use It
For NHS Trusts and other public bodies, the NHS SBS Tech Devices Link 4 framework (reference SBS10515) provides a pre-approved, compliant route to procure IT hardware. This framework runs from 1 April 2025 to 31 March 2028, with an option to extend to March 2029.
A wide range of organisations can access it at no cost and with no minimum order value, including NHS Trusts, CCGs, universities, schools, emergency services, and local authorities. Buyers can use spot buying or run mini-competitions between framework suppliers.
The hardware categories covered are directly relevant to what we sell: networking equipment, wireless access points and controllers, end-user computing devices, peripherals, printers, and smart screens.
Framework purchasing makes sense for larger, planned procurements where you want to benchmark pricing across multiple suppliers. The predecessor framework had an estimated value of around £1 billion and delivered average savings of 25% compared to list prices.
Frameworks aren't always the fastest route, however. For urgent or lower-value hardware needs (a replacement UPS that's failed overnight or a batch of network switches needed this week), a direct PO to a specialist supplier like Hardwarexpress is often faster and equally compliant for below-threshold purchases. We dispatch same-day for orders placed before 3pm, with next-day UK delivery as standard.
How Schools and Universities Can Order Hardware on a PO
University finances are under serious strain. The Office for Students reported in May 2025 that 43% of UK universities expected a deficit for 2024/25. By November 2024, the same regulator warned that nearly 72% of higher education providers could be in deficit by 2025/26. When budgets are this tight, flexible purchasing routes that don't require upfront payment become essential.
Schools face similar pressures. Despite the DfE's £99.7 billion allocation for 2025/26, many schools are dealing with ageing devices and constrained IT budgets. The DfE's buying guidance (updated in January 2025 in collaboration with the National Governance Association) requires schools to follow a staged procurement process based on purchase value. For lower-value hardware, a direct PO to a supplier is the appropriate and compliant route.
Multi-Academy Trusts (MATs) can simplify things further by aggregating orders across multiple schools under a single trade account: one account, one set of credit terms, multiple delivery addresses.
Hardwarexpress accepts official purchase orders from schools, universities, and colleges, with 30-day credit terms available through a trade account. Hardware is dispatched before payment is due, giving procurement teams the breathing room they need to manage cash flow within constrained budgets.
What Must Appear on a Valid Purchase Order
A PO missing key information will cause invoice rejection and payment delays. Make sure every purchase order includes:
- Official PO number (mandatory for NHS invoices; without it, the invoice is returned unpaid)
- Billing address and delivery address (these are often different in public sector organisations)
- Contact name and department
- Itemised product descriptions with quantities and agreed unit prices
- VAT number
- Authorised signatory
For NHS buyers specifically, NHS SBS requires all invoices to be submitted via a PEPPOL-compliant e-invoicing system. Suppliers must be registered and set up for this before invoices can be processed.
Practical tip: Always request a proforma invoice or written quote from Hardwarexpress first, then raise your PO against it. This ensures all figures, product descriptions, and pricing match exactly, avoiding the discrepancies that cause payment delays.
How to Set Up a Trade Account with Hardwarexpress: 3 Steps
Getting set up to order on a purchase order is straightforward. Here's how it works:
- Register: Create an online account at hardwarexpress.co.uk. Public sector organisations (NHS Trusts, schools, universities, councils) can request a trade or credit account during registration or at any time afterwards.
- Apply for 30-day credit: Submit your organisation's details, including official name, billing address, and a contact in your finance or procurement team. We process applications promptly so you're not left waiting.
- Place your order and send your PO: Browse the catalogue, add items to your basket, and proceed to checkout selecting "Purchase Order" as the payment method. Then email or upload your official PO. Orders placed before 3pm qualify for same-day dispatch and next-day UK delivery.
For larger requirements, we offer bulk order enquiries and bespoke quotes. If you need 50 UPS units across multiple sites or a full networking refresh, contact us and we'll put together a competitive proposal.
Trading since 2004, our established supplier relationships mean we can offer pricing passed directly to you without unnecessary mark-ups. Your self-service online account also includes order tracking, wish lists, and express checkout, reducing the admin burden for busy procurement teams.
Hardware Categories Available on Purchase Order
Public sector buyers can order the following product categories via PO from Hardwarexpress:
- UPS (uninterruptible power supply) systems and power protection equipment
- Networking switches and routers
- Wireless access points
- AGM, GEL, and lithium batteries
- Peripherals and accessories
UPS and power protection hardware is increasingly mission-critical for NHS IT teams. The Lord Darzi report identified outdated IT infrastructure as a direct barrier to clinician productivity and Electronic Patient Record (EPR) upgrades. Reliable power protection underpins every server room, comms cabinet, and clinical workstation involved in that digital transformation.
Networking hardware and wireless access points are also explicitly covered under the NHS SBS Link 4 framework, confirming their relevance to public sector procurement priorities.
We hold large stock levels across all these categories, enabling same-day dispatch. That's particularly valuable for IT managers dealing with urgent hardware failures where downtime carries a real operational cost. Our catalogue spans AGM, GEL, and lithium battery types alongside power protection and networking, a breadth rarely matched by generalist suppliers.
