With the NS4 ITT expected on 21st August and a submission deadline of 2nd October, the clock is ticking for telecoms and network suppliers who want a place on one of the most significant public sector frameworks in years. For some, that means scrambling to get documentation in order. For the well-prepared, it means refining work that’s already underway.
But even for suppliers who nail the application, there’s a harder question on the other side: how do you actually turn a framework listing into contracts? Getting onto NS4 is a meaningful achievement. It is not, on its own, a commercial strategy. This article covers both what a strong application looks like and what to do with it once you’re listed.
Why NS4 will be harder to get listed on
Let’s get the good news out of the way first. NS4 simplifies the lot structure considerably — NS3’s sprawling categories and sublots have been consolidated into a cleaner set of individual lots, making the framework much easier to navigate. Buyers will find it more straightforward to procure what they need. That’s genuinely positive.
Now for the bit that should sharpen your focus. A simpler lot structure means broader lots, and broader lots attract more competition. The niches where suppliers could quietly sit on NS3 without facing much pressure are largely gone. Add to that the fact that GCA is raising the qualification bar across its frameworks — the submission requirements for NS4 are more demanding than they were for NS3 — and you’ve got a framework that rewards preparation far more than its predecessor did.
There’s also a new dimension to contend with. Three additional lots have been introduced specifically to support the Emergency Services Network transition, which brings a wave of specialist suppliers into scope who weren’t previously in the frame. The competitive landscape for NS4 is simply wider than it was for NS3.
None of this is a reason to hesitate. It’s a reason to start early.
Getting through the door: what the qualification requires
The full ITT isn’t out yet. GCA is targeting August 2026 for publication, so the complete picture isn’t available. But based on the direction of the pre-market engagement and GCA’s wider approach to standardising requirements, here’s what suppliers should be getting ready for now.
Your financials will be assessed against turnover thresholds relative to the lots you’re applying for. If you’re a smaller supplier with ambitions for higher-value lots, it’s worth modelling this out early rather than getting a nasty surprise mid-application.
On the technical side, you’ll need to demonstrate real experience delivering the services covered by your target lots. Not a capability statement. Not a slide deck about your methodology. Evidence – named contracts, quantified outcomes, specific problems you solved. If you can’t point to a concrete example, you effectively haven’t answered the question.
Cyber Essentials Plus is a baseline expectation for a framework of this nature, so if you’re not certified, factor in the time and cost now. Similarly, your Carbon Reduction Plan needs to be current and published – this is required under PPN 015, and it still catches suppliers out. Round it out with appropriate insurance levels across public liability, professional indemnity and employer’s liability. GCA has confirmed these are consistent across all lots.
One thing suppliers sometimes worry about: ISO accreditations. GCA confirmed these are not required at framework level for NS4, though they may be requested by buyers at call-off level, so it’s worth having if you can.
GCA is running weekly supplier surgery drop-in sessions through July and August, specifically so you can ask these questions directly before the formal window opens. They’re worth your time.
Writing an application that scores well
Here’s something assessors won’t tell you but that holds true across almost every framework: the difference between a listing and a rejection usually isn’t capability. It’s evidence, and how well that evidence is matched to what’s being asked.
The most common mistake is writing about what you can do rather than what you have done. Assessors aren’t marking you on the ambition of your service offering – they’re marking you against scoring criteria, and those criteria want proof. For every question, the mental check should be: can I back this up with a specific contract, a named outcome, a real situation? If the answer is no, you’re not ready to answer that question yet.
Lot selection matters more than most suppliers realise. A focused application with strong, directly relevant evidence for three lots will consistently outperform a sprawling attempt to cover seven with evidence that’s been stretched to fit. Assessors can tell when a WAN reference has been repurposed to answer a contact centre question. It doesn’t land well.
And don’t treat the mandatory compliance sections as the finish line. Meeting the threshold requirements gets you through — it doesn’t get you ranked well. The scored qualitative responses are where positions are won or lost, and they deserve the same rigour you’d bring to a live bid. That means drafting, reviewing against the criteria, and revising. Not a single pass the night before submission.
One more thing worth flagging: framework applications touch a lot of different parts of a business. Finance, legal, operations, delivery – they all have a role. The person who can write the most compelling contract reference is rarely the same person coordinating the submission. Build in time for that, because leaving it to the final fortnight is how avoidable mistakes happen.
From listed to winning: the part most suppliers get wrong
A framework listing is a commercial asset. Treated as one, it generates pipeline. Treated as a compliance exercise, it gathers dust.
The suppliers who do consistently well through frameworks understand something that others take too long to learn: buyers are busy, and they work from shortlists. When a requirement comes up, they’re not starting from scratch and browsing the full supplier list — they’re going to the names they already know, the ones they’ve seen at events, read content from, or been recommended by a peer. If a buyer has never heard of you, your NS4 listing won’t change that.
So the work that matters most after award is the work that creates familiarity before requirements land. That means being present in the channels public sector buyers actually use — sector events, procurement webinars, GCA communications, public sector networks — and having a website and content that reflects the problems you actually solve for the organisations you want to work with. Buyers do their research before they reach out. Make it easy for them to find you and understand what you do.
Don’t underestimate the commercial value of your existing relationships either. Letting current public sector clients know you’re listed on NS4 is one of the most straightforward conversations you can have, and a warm extension or expansion discussion is considerably easier than a cold pursuit of a new buyer.
It’s also worth thinking carefully about how direct awards work in practice. A significant volume of lower-value call-offs under NS4 won’t go to further competition — buyers will make direct awards, and their justification will be based on which listed supplier they already have confidence in. That confidence comes from visibility, from clear service descriptions, from accessible case studies. The suppliers who make the buyer’s job easy are the ones who win this work.
The window is shorter than it looks
The ITT lands on 21st August. Applications close on 2nd October. That’s ten weeks from ITT to submission deadline – less time than most suppliers expect, and far less time than most need if they’re starting from scratch.
The suppliers who submit strong applications are the ones who treated the pre-ITT period as preparation time, not waiting time. They’ve identified which lots they’re going for, developed their strongest contract references, sorted their compliance documentation, and attended the GCA engagement sessions to get ahead of any surprises. By the time the formal window opens, they’re refining – not starting.
