An estimated £10-£15 Billion in potential annual revenue is lost to regional SMEs due to structural procurement barriers.

The SME Matching Scheme

To help address this SME revenue shortfall, our new collaboration approach is empowering Chambers of Commerce to become the trusted doorway for SME inclusions within multi-million-pound major Tier 1 public procurement supply chains; to hardwire public spending into local business communities and start to address this known £10-£15 billion revenue shortfall.

Why We Are Doing This?

Our research found that across UK public sector supply chains, an estimated £10 Billion to £15 Billion in potential annual revenue is lost to regional SMEs due to structural procurement barriers. But, when factored through the Local Multiplier Effect (LM3), this translates to an estimated £16 Billion to £27 Billion in lost economic value for local high streets and regional communities every year (LM3 is the standard, accredited economic methodology used by UK local authorities and public bodies to measure geographic money flows and local supply chain re-spending).

Breaking-down this £10-15bn Public Procurement Shortfall

UK public bodies spend roughly 20% to 21% (£45.2bn) directly with SMEs against a government ambition/target of 33% (1 in every £3). This 12-13% gap represents £15 Billion annually in potential revenue missing from regional SME supply chains. While Local Authorities spend c34–35% with SMEs, Central Government lags behind at just 10%–16%.

Statutory Recognition of SME Spending as Social Value

Directives are pushing and redirecting public sector supply chain subcontracts into local SMEs and VCSEs, by explicitly classifying this as statutory Social Value, rather than simple commercial expenditure.

- UK Procurement Act 2023: Mandates that contracting authorities actively consider local economic growth, supplier diversity, and removing structural barriers for small businesses.

Chambers of Commerce Historically Struggle to Connect SMEs to Tier 1 Supply Chains...

1. Traditional Operational Focus (Networking vs. Technical Procurement)

The Gap: Historically, Chambers have operated as networking bodies, business advocates, and civic membership organisations. Their primary revenue models rely on membership fees, events, and business training—not active supply chain brokering.

The Result: They facilitate introductions, but lack the formal procurement architecture required to take an SME from a handshake at an event to a compliant subcontractor on a multi-million-pound contract.

2. The Compliance & De-Risking Bottleneck

The Gap: Tier 1 contractors operate under strict corporate risk frameworks. Before an SME can join a major supply chain, they must pass rigorous audits on Health & Safety, financial stability, Cyber Essentials, and Modern Slavery compliance.

The Result: Chambers rarely have the internal capacity, standardised toolkits, or legal frameworks to vet and badge their members as "tender-ready" for major Tier 1 contractors at scale.

3. Lack of Integration with Tier 1 Bidding Cycles

The Gap: Tier 1 contractor teams move quickly during bid submission phases. They require instant, filterable access to localised capacity (by postcode, trade, capability, and insurance limit) to satisfy local spend targets in tenders.

The Result: Without a dedicated digital marketplace, Chambers rely on manual referrals or offline directories, which are too slow and unstandardised for high-speed corporate bid teams.

4. No Mechanism to Lock In or Track Post-Award Data

How the SME Matching Scheme Solves This...

Within the Pluggin Marketplace, the Scheme fills these gaps by equipping Chambers with the missing digital engine:

1. Pluggin provides cost-free access to the digital Marketplace and a Tier 1 major contractsupplier network, so that a chamber then provides the local SME community, trust and validation.
2. A chamber's "SME Readiness Pathway" standardises compliance so Tier 1 contract suppliers can locally source pre-validated SME sub-contractors.
3. The Pluggin DICM Engine turns informal local introductions into contractually locked, auditable social value data for UK public buyers.

"Chambers can transform SME member revenues into recognised public social value from major contract supplier brands. When local SMEs win work on major public contracts, that money recirculates through local communities - the Pluggin Marketplace then becoming the proving ground of a Chamber's direct role in building local wealth."

How the Scheme Operates

The Pluggin Marketplace operates as a closed-loop collaboration environment, within which regional Chambers of Commerce become the access-point for major suppliers operating within regions.

The SME Matching Scheme establishes a Chamber of Commerce into the trusted doorway for major business suppliers operating multi-million and multi-year Tier 1 contracts with public buying authorities; enabling our public buyers to remove financial barriers for local businesses and ensure contract spending flows-back to SMES and the local economy.

Step 1

Onboarding & Self-Assessment

Local businesses join the Pluggin Ecosystem under the SME Matching Scheme, where they specify their SME status, geographic coverage and Chamber membership details.

Step 2

The Chamber Readiness Pathway

Chambers support SMEs for contract readiness:

Standard Compliance
Tender Capability
"Tender-Ready" Badging

Step 3

Tier 1 Sourcing & Engagement

When a Tier 1 contractor bids for a public contract within the Pluggin Marketplace, they approach a Chamber doorway to identify SME local suppliers to join their supply chain.

Step 4

Commercial Lock-in & Closed Data Loop

As a main contract is awarded to the Tier 1 supplier, their supply chain becomes contractually locked within the Pluggin DICM Engine - live data feeding into the Buyer Dashboard.

Zero Fees & Complete Chamber Autonomy

Local economic growth derived from public spending with major Tier 1 suppliers, should not be taxed by digital platforms!

The Pluggin Ecosystem charges no fees or commissions to Chambers of Commerce or member SMEs for onboarding, validation, matching, or sub-contract creation.

Each Chamber of Commerce has complete Financial Autonomy, where they independently decide whether or not to develop their own localised charging or commercial mechanism outside of the Pluggin Marketplace.

"SME revenue isn't just commercial spend—it is the engine of Theme 1 of PPN 06/20. By trapping public procurement spend inside local postcodes via Chamber-validated SMEs, the Pluggin DICM Engine turns every subcontract pound into verifiable, multi-layered regional economic growth."

How does this scheme meet Welsh Tier 1 procurement requirements?

In Wales, major contractors are bound by the Social Partnership and Public Procurement (Wales) Act 2023 and the Welsh Procurement Policy Statement (WPPS). Winning and retaining public contracts requires proving that supply chain spend directly supports the Welsh Foundational Economy.

The Challenge for Tier 1s in Wales:

Securing compliant, de-risked Welsh SMEs and providing verifiable evidence of local Welsh subcontract spend to public buying authorities under statutory Section 39 reporting.

The Pluggin Solution for Welsh Contracts:

Chamber-Validated Welsh SMEs: Instant access to pre-vetted local suppliers through regional Welsh Chambers of Commerce (e.g., South Wales Chamber, West & North Wales Chamber).
Social Purchase Orders (SPOs): Lock in local Welsh postcode spend commitments upon main contract award, stopping corporate spend leakage out of Wales.
Automated SPPPA Reporting: The Pluggin DICM Engine automatically feeds verified, real-time subcontract spend directly onto Welsh Public Buyer Dashboards, satisfying statutory reporting duties to Welsh Ministers without manual administrative overhead.

In fact, the scheme is even stronger in Wales. Welsh public authorities have a statutory legal duty to annually report supply chain spend to Welsh Ministers, making the scheme an operational necessity rather than just a nice-to-have.

"Buying local isn't just a corporate promise; under PPN 06/20 and MAC 1.1, it is a scored award criterion. By executing local SME subcontracts within the Pluggin Marketplace, major suppliers convert operational supply chain spend into legally locked, auditable Social Value points that win bids."
