There is no single “NHS supplier” list to get onto
The frustration in the original question is common and it comes from a wrong mental model. People imagine one door marked “NHS supplier”, queue at it, and wonder why the due diligence is so long and why the NHS keeps trying to cut out the middleman. There is no single door. The NHS buys through at least three separate routes, and the one you use depends on whether you sell goods or services, and at what value. Pick the wrong route and you will spend months on a process that was never going to fit what you sell.
Here is how the routes actually work, and which one a small product supplier should aim at first.
NHS Supply Chain is a frameworks business, not a shop
NHS Supply Chain is run by Supply Chain Coordination Limited (SCCL), a limited company whose shares are owned by NHS England (checked August 2026). It aggregates demand across a large number of trusts and buys at national scale, which is exactly why a distributor or reseller finds it hard: the model is designed to consolidate spend and squeeze out the margin a middleman adds. If you manufacture, that scale is the attraction. If you resell, it is the obstacle, and that is worth knowing before you invest in the application.
You get onto NHS Supply Chain by winning a place on one of its framework agreements. Those frameworks are competed openly and advertised as notices on Find a Tender, the national notice service. They run for a fixed term, commonly a few years, after which they are recompeted. The practical consequence catches people out: once a framework is awarded and closed, you cannot simply apply to join it. You wait for the recompete, or you look for a dynamic market or dynamic purchasing system in your category, which has to accept membership applications at any point during its term. NHS Supply Chain points at a third way round as well: supplying through a distributor that already holds a place on the framework. For a supplier without a public-sector track record, the open-all-the-time route is usually the more realistic first target.
Each product area has a category team. If you sell into a category, the useful early move is to identify the relevant framework, note when its current term ends, and engage the category manager well before the recompete. NHS Supply Chain plans tender activity around a year ahead of a current arrangement expiring and points suppliers at the window 9 to 15 months before that date, so turning up the week the notice is published is turning up late.
If you sell services, you are in a different regime entirely
This is where most of the confusion sits. Health care services are not procured under the same rules as goods. Since 1 January 2024 the procurement of health care services by the NHS in England has run under the Provider Selection Regime, a separate set of rules made under powers the Health and Care Act 2022 inserted into the NHS Act 2006. The PSR has its own selection processes, including direct award routes and a most-suitable- provider process, and it exists because clinical service continuity is a different problem from buying gloves.
The point for a product supplier is simple: the PSR is not for buying goods on their own. Goods only fall inside it when they ride along with a health care service that is the main subject of the contract. If you sell equipment, consumables or devices, you are not in the PSR world at all; you are under the Procurement Act 2023, the general procurement law that went live on 24 February 2025. Read a blog aimed at care providers and you will be told to worry about PSR processes that have nothing to do with you. Know which regime your product sits in before you read anything else about NHS procurement.
The realistic first door: buying below the threshold
Nationally competed frameworks are the slow, high-volume route. The faster door for a small supplier is the individual trust, and it opens below the procurement threshold.
Under the Procurement Act, above a set contract value a buyer must run a formal, advertised procurement. Below that value the buyer has more freedom: an NHS trust can approach suppliers directly, ask for a couple of quotes, and award without a full tender. Trusts and foundation trusts count as central government authorities under the Act, which puts their threshold for goods and services at £135,018 including VAT as at August 2026. That figure changed on 1 January 2026 and will move again, so check it rather than quoting it back at anyone. Integrated care boards sit in the sub-central band, where it is £207,720. A great deal of trust spend on consumables, small equipment and one-off supply falls below those lines, and there a trust can simply choose to buy from you.
The freedom is not total. If a trust advertises a below-threshold contract worth £12,000 or more it has to publish a notice first and a contract details notice after award, and it cannot screen bidders on a supplier suitability assessment. What it can still do is approach named suppliers directly, and that is the door you are actually knocking on.
That is the door to aim at first. Win a small direct order or a below-threshold contract with one trust, deliver it well, and you have the two things every framework evaluation asks for and a new supplier lacks: a public-sector reference and evidence you can meet NHS terms. Trusts publish their own tender and quote opportunities on their e-procurement portals, and most of them through Atamis, the shared NHS eCommercial system, so registering on those and watching your category is more productive in year one than waiting for a national framework to reopen.
What the due diligence actually asks for
The due diligence that frustrates people is mostly the same standing checks any public buyer runs, applied to a safety-critical setting. Expect to register your core business details once on the central digital platform that sits behind Find a Tender, so you enter them once and reuse them across bids. Expect questions on financial standing, insurance, and quality management. Expect, if you supply anything clinical, to evidence the regulatory basics: a medical device has to be registered with the MHRA and carry the correct conformity marking before it can be placed on the Great Britain market, and a buyer will ask you to prove it.
There is one certification requirement you cannot argue with. NHS Supply Chain states that suppliers must hold a current BS EN ISO 9001:2015 or BS EN ISO 13485:2016 certificate accredited by UKAS or an equivalent recognised body, covering the supply chain including manufacturing, storage and distribution, and that committing to obtain certification is not sufficient: the evidence goes in with the bid. Beyond that, whether a standard is required is set out in the individual tender’s own documents, so read those before you buy accreditation on a certification body’s say-so. We make the same point in our piece on whether ISO 9001 is worth it: away from NHS Supply Chain’s own frameworks a standard is a gate on some contracts and a nice-to-have on others, and the tender tells you which.
Our view
Stop trying to get onto “the NHS supplier list”, because it does not exist, and stop starting with the national framework, because it is the hardest door and it is usually shut. Work out first whether you sell goods (Procurement Act) or health care services (Provider Selection Regime), because that alone rules out half the advice you will read. Then go trust by trust, below the threshold, and win the small contracts that build the reference and the financial evidence a framework recompete will demand. By the time the national framework reopens, you turn up with a delivery record instead of a cold application.
This is the sort of route-planning our NHS and social care bid support exists for: working out which door fits what you sell, and getting you through it. Our older guide to NHS tenders sets out the wider picture; this is the part it did not cover.
