Network Services 4 Explained: What Do Suppliers Need to Know?

The Government Commercial Agency's (GCA's) upcoming Network Services 4 (RM6377) framework represents one of the largest technology procurement opportunities currently on the horizon for UK suppliers.

With an estimated value of £8 billion, updated procurement routes and an expanded scope covering everything from connectivity and unified communications through to IoT, audio visual services and critical communications, Network Services 4 is expected to become one of the UK's most significant public sector technology frameworks.

For suppliers already operating within the public sector (or those looking to enter it) preparation should begin well before the Invitation to Tender (ITT) is published.

In this guide, we explain what Network Services 4 is, what's changing compared to its predecessor, and what suppliers should be doing now to maximise their chances of securing a place.

‍

What is Network Services 4?

Network Services 4 (RM6377) is the successor to the current Network Services 3 agreement and has been developed by the GCA to provide public sector organisations with access to a wide range of network and communications technologies.

The framework has been designed to:

• Build upon the success of Network Services 3
• Reflect changes across the technology market
• Introduce new service areas where buyer demand has evolved
• Align procurement with the Procurement Act 2023
• Provide buyers with greater flexibility when purchasing services

According to GCA, previous Network Services agreements have already facilitated over £5.1 billion of spend, with Network Services 4 expected to support around £8 billion worth of public sector procurement during its lifetime.

Key Dates Suppliers Should Know

Although all dates remain subject to change until the tender is officially published, the current proposed timetable includes:

ITT Release: 21 August 2026

Clarification Deadline: 25th September 2026

Bid Submission Deadline:: 2nd October 2026

Intention to Award: 8th March 2027

Framework Award: 17th March 2027

Framework Live: 15th April 2027

This leaves suppliers with a relatively short submission window once the tender is released, making early preparation essential.

‍

What Services Does Network Services 4 Cover?

One of the biggest developments within Network Services 4 is its expanded scope.

The framework has been structured into 11 lots covering a broad range of technology solutions.

These include:

• Lot 1 – Internet Connectivity Services (WAN)
• Lot 2 – Local Connectivity Services (LAN)
• Lot 3 – Voice and Unified Communications
• Lot 4 – Contact Centre Services
• Lot 5 – IoT and Connected Places (including Security and CCTV)
• Lot 6 – Critical Domain Services
• Lot 7 – Paging and Alerting
• Lot 8 – Audio Visual Services
• Lot 9a – Critical Communications Devices
• Lot 9b – Critical Communications Services
• Lot 9c – Critical Communications Software

Several notable changes have been introduced, including:

• WAN and LAN remaining separate following market engagement
• Voice and Contact Centre services being aligned with current market trends
• A brand-new Audio Visual Services lot
• Three additional Critical Communications lots supporting the Emergency Services Network (ESN) transition

These changes significantly broaden the framework's reach and create opportunities for suppliers operating across multiple technology sectors.

‍

New Buying Routes

Network Services 4 introduces greater flexibility for buyers through three procurement options:

Award Without Competition (AWOC)

Suppliers publish catalogue service offers that buyers can purchase directly where appropriate, using objective assessment mechanisms such as price.

Swift Buy

A streamlined single-stage competitive process allowing buyers to request confirmation of service availability before making an award.

Competitive Flexible Procedure

Designed for more complex procurements, this route allows buyers to conduct tailored competitions that may include multiple stages, negotiation and bespoke evaluation approaches.

These buying routes are intended to simplify procurement while giving contracting authorities greater flexibility depending on the complexity of their requirements.

‍

What Will Suppliers Be Assessed On?

Winning a place on Network Services 4 won't simply be about offering competitive pricing.

GCA has outlined three core evaluation areas:

Quality (75%)

Quality forms the majority of the evaluation and will include:

• Multi-lot award questions
• Lot-specific technical responses

This means suppliers will need clear, evidence-backed answers demonstrating technical capability, delivery experience and understanding of buyer requirements.

Price (15%)

Pricing will assess both:

• Product pricing
• Professional services pricing

depending on the relevant lot.

Social Value (10%)

Suppliers will also need to demonstrate their commitment to the government's Social Value Model through the required declaration.

Although currently assessed on a pass/fail basis, social value remains an essential compliance requirement.

‍

Compliance Requirements

Based on the current supplier engagement information, bidders are expected to meet a number of conditions of participation, including:

• Technical Ability Certificates (TACs)
• Financial Viability Risk Assessment (FVRA)
• Cyber Essentials
• Prompt Payment compliance
• Carbon Reduction Plan
• Modern Slavery Risk Assessment

Final requirements will be confirmed in the published tender documentation.

Suppliers must also hold the required insurance levels, including:

• £1 million Public Liability
• £5 million Employer's Liability
• £1 million Professional Indemnity
• £1 million Product Liability

It's worth noting that some compliance requirements vary between lots, so suppliers should review the final documentation carefully once released.

‍

Why Preparation Matters

Although the tender isn't yet live, this is arguably the most valuable stage of the process.

Many unsuccessful framework applications fail not because suppliers lack capability, but because they leave preparation until the tender is published.

By the time Network Services 4 opens, suppliers should already have:

• Relevant case studies
• Customer references
• Evidence of similar contracts
• Updated policies
• Financial information
• Social Value evidence
• Carbon Reduction documentation
• Cyber Essentials certification where required
• Draft responses prepared for likely evaluation themes

Having this material ready allows more time to focus on producing high-quality answers rather than rushing to gather evidence under tight deadlines.

How Bid Writing Service Can Help

Preparing for a major framework such as Network Services 4 involves far more than simply writing responses.

At BWS, we help organisations become genuinely framework ready by supporting every stage of the process, including:

• Framework suitability assessments
• Compliance reviews
• Technical bid writing
• Evidence gathering
• Social Value support
• Carbon Reduction Plans
• Policy development
• Final quality assurance before submission

Our approach is designed to ensure businesses enter the tender period with the strongest possible foundation, rather than trying to prepare against the clock. This aligns with our wider framework readiness strategy, helping suppliers address compliance, technical responses and supporting documentation well before opportunities open.

Final Thoughts

Network Services 4 is set to become one of the UK's largest public sector technology frameworks, presenting significant opportunities for suppliers across connectivity, communications, infrastructure and digital services.

While the final tender documentation will ultimately determine the exact requirements, the current supplier engagement information provides a clear indication of what buyers will expect.

Suppliers who start preparing now (reviewing their compliance, strengthening their evidence base and identifying the most appropriate lots) will be in a far stronger position once the ITT is published.

If you're planning to bid for Network Services 4, early preparation could make the difference between simply submitting a bid and securing a place on the framework.
