Optimised agency roster examples for UK marketing leaders
Three ready-to-use roster models cover the vast majority of UK marketing structures. The lean roster suits teams of up to 15 people with a focused channel mix: two to four specialist agencies, clear statements of work (SOWs), and a single internal owner. The hub-and-spoke roster fits mid-size organisations running multiple channels from a central brand agency, with two to four specialist partners feeding into it. The specialist network roster works for complex, multi-market organisations that need deep expertise across six or more disciplines, coordinated by a procurement-led governance layer.
An optimised agency roster is not a directory. It is a curated operating model where every partner has a defined role, a non-overlapping SOW, and a performance filter that determines whether they stay on the roster at the next review.
- Lean roster: 2–4 agencies, single internal owner, SOW-led, low overhead.
- Hub-and-spoke roster: 1 lead agency plus 2–4 specialists, brand-led coordination, medium complexity.
- Specialist network roster: multiple agencies, procurement-governed, capability-mapped, high channel complexity.
Pro Tip: If you are starting a rationalisation and want low disruption, freeze new agency appointments for 90 days, map current spend by supplier, and identify the two or three partners already delivering the most consistent output. Build the new roster around them.
Key takeaways
An optimised agency roster requires a named internal owner, non-overlapping SOWs, a quarterly scoring cadence, and a model matched to your organisation’s size, budget, and channel complexity.
| Point | Details |
|---|---|
| Choose the right model first | Match lean, hub-and-spoke, or specialist network to your team size, budget, and channel mix before shortlisting agencies. |
| SOWs prevent overlap | Every agency SOW must include an explicit out-of-scope clause naming the functions owned by other roster partners. |
| Name an owner before launch | Appoint a roster operations owner before the first QBR; without one, reviews slip and underperformers stay. |
| Score agencies from day one | Use a five-category KPI scorecard from the first project, not just at formal reviews, to build a performance baseline quickly. |
| Michaelbell as embedded partner | Michaelbell designs rosters, drafts SOWs, and runs SRM cycles for UK clients, acting as hub agency or governance support. |

What do optimised agency roster examples actually look like?
The lean roster: worked example
A lean roster, as Breef’s guidance on building agency rosters for growing businesses confirms, gives small teams specialist capability without the cost of full-time hires. The SOW is the engine: each agency receives a document that defines scope, deliverables, revision rounds, and what sits explicitly outside their remit.
Typical role map:
- Internal owner: Marketing Manager (signs SOWs, owns vendor performance, chairs monthly alignment calls).
- Agency 1: Brand and creative (campaign concepts, brand guidelines, copywriting).
- Agency 2: Digital and paid media (paid social, PPC, reporting).
- Agency 3 (optional): PR or specialist content.
Sample roster matrix (lean):
Primary = owns delivery. Secondary = supports or reviews. — = out of scope.
The hub-and-spoke roster: worked example
Here, a lead agency (the hub) holds the brand strategy and creative direction. Specialist agencies (the spokes) execute in their lanes. The hub agency reviews all output for brand consistency before it goes live, which removes the need for the internal team to referee creative disputes.
Typical role map:
- Internal owner: Head of Marketing plus Procurement Business Partner (joint sign-off on SOWs above a defined threshold, typically £25,000 per project).
- Hub agency: Brand strategy, creative direction, campaign planning, brand governance.
- Spoke 1: Performance media buying.
- Spoke 2: CRM and email marketing.
- Spoke 3: Video production.
- Spoke 4 (optional): Out-of-home and direct mail.
The hub agency’s SOW must explicitly include a brand governance clause: the right to review and approve all spoke output before publication. Without this clause, brand drift is almost inevitable within six months.
The specialist network roster: worked example
This model suits organisations with complex channel mixes, multiple markets, or regulated communications requirements. Aligning your roster to your advertising model depends on organisational structure: centralised businesses consolidate spend with fewer partners; decentralised ones need a broader collaborative network.
Typical role map:
- Internal owner: Marketing Director plus dedicated Procurement Manager.
- Roster operations owner: A named individual (often a senior marketing manager) who tracks SOW status, performance scores, and renewal dates across all partners.
- Agencies: Segmented by capability: brand, performance, CRM, PR, social, production, specialist (e.g. accessibility, localisation).
Pro Tip: In a specialist network, use a capability ownership label for every function: Primary (owns delivery), Secondary (supports), Rare (called in for specific projects only). This prevents two agencies billing for the same output.
A searchable roster database with structured fields increases utilisation and cuts time to shortlist. Track each agency’s capabilities, rate card ranges, certifications, performance scores, and last review date.

How do you choose the right roster model for your organisation?
The right model follows your organisational structure, not your preference. ClickZ’s analysis of roster alignment is clear: the number of agencies on a roster should reflect how the organisation is managed and how the roster will be operated day to day.
Decision criteria:
Trade-offs to expect:
- Lean rosters reduce overhead and invoice friction but concentrate risk in a small number of partners.
- Hub-and-spoke models give strong brand control but slow execution if the hub becomes a bottleneck.
- Specialist networks offer deep expertise and agility but require significant governance investment to prevent duplication.
Practical next steps before choosing:
- Map your current spend by supplier and identify gaps or overlaps.
- Write a one-page capability map: which functions you need covered, at what volume, and at what frequency.
- Agree governance role descriptions with procurement before shortlisting agencies. Who signs SOWs? Who owns performance reviews? Who has authority to remove a partner?
Exploring types of creative agency partnerships in detail before you commit to a model helps you avoid locking in a structure that does not match how your team actually works.
What governance and SRM does an optimised roster need?
An agency roster review is a recognised industry practice: a strategic evaluation that reassesses supplier fit and alignment with brand objectives. Without a structured review cadence, rosters drift. Partners accumulate. Costs rise. Accountability disappears.
Internal ownership roles
- Marketing lead: Owns the strategic relationship with each agency, chairs quarterly business reviews (QBRs), and approves creative briefs.
- Procurement sponsor: Signs commercial agreements, manages rate card compliance, and leads annual strategic reviews.
- Roster operations owner: Tracks SOW status, performance scores, renewal dates, and flags underperformance between formal reviews.
Suggested review cadence
- Monthly: Brief alignment call (30 minutes) between internal owner and each active agency. Focus: live projects, blockers, upcoming briefs.
- Quarterly: QBR covering delivery reliability, creative effectiveness, commercial compliance, and responsiveness. Score each agency against the KPI scorecard.
- Annually: Strategic review. Reassess whether each partner’s capabilities still match organisational needs. Decide on renewals, replacements, or scope changes.
- End of project: Debrief within two weeks. Capture what worked, what did not, and any scope creep that needs addressing in the next SOW.
Sample KPI scorecard categories
| KPI category | Example measures |
|---|---|
| Delivery reliability | On-time delivery rate, revision rounds per project |
| Creative effectiveness | Brand consistency score, campaign performance vs. benchmark |
| Commercial compliance | Invoices matching SOW, rate card adherence |
| Responsiveness | Average response time to briefs, escalation handling |
| ROI measures | Cost per output, media efficiency, lead quality |
Incorporating anonymous feedback from internal stakeholders into QBR scoring gives procurement a fuller picture than delivery metrics alone. AI orchestration tools have demonstrated substantial reductions in administrative time in published case studies, improving reporting timeliness and freeing SRM resource for higher-value relationship work.
Pro Tip: Score each agency out of 100 at every QBR. Agencies scoring below 65 for two consecutive quarters enter a formal improvement plan. Agencies scoring above 85 consistently are candidates for expanded scope.
What does a roster redesign cost and how long does it take?
Realistic timelines and budget expectations prevent the most common cause of roster projects stalling: underestimating the internal resource required.
Typical phases:
- Discovery (4–6 weeks): Spend analysis, capability mapping, stakeholder interviews, current SOW audit.
- Shortlisting (4–8 weeks): RFI or mini-competition, capability scoring, reference checks, rate card benchmarking.
- Pilot (8–12 weeks): One or two new partners tested on live briefs with defined success criteria.
- Migration (4–8 weeks): Transition of active projects from outgoing to incoming agencies, handover documentation, knowledge transfer.
- Embed (ongoing, first 6 months): Monthly alignment calls, first QBR at month three, scorecard calibration.
Budget considerations:
- Internal resource time is the largest hidden cost. A thorough discovery phase typically requires 20–30 days of senior marketing and procurement time.
- External consultancy or procurement support for a full roster redesign in the UK market typically ranges from a light-touch advisory engagement to a managed procurement exercise, depending on the number of agencies in scope.
- Transitional supplier costs: outgoing agencies may have notice periods of 30–90 days under existing contracts. Budget for overlap.
- Contingency: allow 15–20% on top of estimated external costs for scope changes and extended negotiations.
UK procurement steps to plan for:
- If your organisation follows public procurement rules or internal governance thresholds, a formal tender or mini-competition may be required above certain contract values.
- SOW negotiation with a new agency typically takes two to four weeks from heads of agreement to signed document.
- Phase consolidation to maintain campaign continuity: never migrate more than two agencies simultaneously, and always keep one active campaign running with an incumbent until the new partner has delivered at least one approved project.
Which tools and templates make roster management repeatable?
Roster management becomes audit-ready when it runs on structured tools rather than email threads and spreadsheets. Automation in agency operations can decouple execution from account management, increasing capacity without proportional headcount growth.
Tool categories to consider:
- Roster directory: A searchable database (Airtable, Notion, or a CRM module) where each agency record holds capabilities, rate card ranges, certifications, performance notes, and contract renewal dates.
- Scorecard platform: A shared scoring tool (even a structured Google Sheet) where QBR scores are recorded and trended over time.
- Project handoff and shared calendar: A project management tool (Asana, Monday.com, or Microsoft Planner) with a shared calendar showing brief deadlines, review dates, and campaign milestones.
- Financial tracking: A simple spend tracker linked to purchase orders, showing actual vs. SOW-budgeted spend per agency per quarter.
Fields to track in your roster directory:
| Field | Why it matters |
|---|---|
| Agency name and contact | Basic identification and escalation path |
| Capability tags | Enables fast shortlisting for new briefs |
| Rate card ranges | Supports commercial compliance checks |
| Certifications and accreditations | Relevant for regulated sectors and procurement audits |
| Performance score (latest QBR) | Surfaces underperformers before renewal |
| Contract renewal date | Prevents accidental rollovers |
| SOW reference numbers | Links performance data to specific scopes |
Templates to create now:
- Roster matrix spreadsheet (functions vs. agencies, Primary/Secondary/Rare labels).
- KPI scorecard template (five categories, 20-point scale each, quarterly scoring).
- SOW template with explicit scope boundaries and an out-of-scope clause.
- Vendor onboarding checklist (insurance certificates, data processing agreements, brand guidelines sign-off, rate card confirmation).
For organisations using white-label or shared-infrastructure models, capacity mapping by client account is critical. Sharing agency resource across client accounts without isolation creates quality and compliance risks that are difficult to unpick after the fact. Magnifi2’s white-label operational model illustrates how structured capacity assignment prevents these issues at scale.
What are the most common pitfalls when rationalising a roster?
Most roster projects fail in the same five ways.
Pitfall 1: Unclear SOWs. When scope is vague, two agencies bill for the same output. Fix: every SOW must include an explicit out-of-scope clause listing the functions owned by other roster partners.
Pitfall 2: Too many small vendors. Fifteen agencies each doing small, irregular projects creates invoice chaos and no accountability. Fix: consolidate to the fewest partners that cover your capability needs, then use the lean or hub-and-spoke model as your target state.
Pitfall 3: No named internal owner. Without one person responsible for roster health, reviews slip and underperformers stay. Fix: appoint a roster operations owner before the first QBR, even if it is a part-time responsibility.
Pitfall 4: Poor handover planning. Migrating a campaign from one agency to another without a structured handover document loses institutional knowledge and delays go-live. Fix: require a handover pack (live assets, brand files, audience data, campaign notes) as a contractual deliverable from every outgoing agency.

Pitfall 5: No cost tracking by agency. Spend that is not tracked by supplier cannot be benchmarked or challenged at renewal. Fix: link every purchase order to a supplier code and run a quarterly spend report before each QBR.
Pro Tip: To preserve creative continuity during consolidation, brief the incoming agency on the outgoing agency’s creative rationale, not just the brand guidelines. Ask the outgoing agency to produce a creative handover note as part of their exit deliverable. Most will comply if it is written into the contract.
How MB Brand Communications approaches roster design for UK clients
The following example draws on a roster engagement Michaelbell completed for a UK-based B2B services client moving from an unmanaged roster of eleven agencies to a structured hub-and-spoke model.
Project context: The client had grown rapidly through acquisition and inherited a fragmented supplier base. Marketing spend was spread across eleven agencies with overlapping scopes, no performance data, and three separate retainer agreements for what was effectively the same creative function.
Chosen model: Hub-and-spoke. Michaelbell acted as the hub, holding brand strategy, campaign planning, and creative direction. Three specialist partners were retained for performance media, CRM, and video production respectively.
Operational model:
- Michaelbell owned SOW drafting and brand governance across all four partners.
- The client’s Head of Marketing held commercial sign-off above £25,000.
- A procurement business partner joined the annual strategic review and all SOW negotiations.
- QBRs ran quarterly; end-of-project debriefs ran within ten working days of campaign completion.
Outcomes:
- Supplier count reduced from eleven to four.
- Invoice processing time fell significantly as overlapping scopes were eliminated.
- The client’s marketing team reported clearer accountability and faster brief-to-delivery cycles within the first two quarters.
Lessons from this engagement:
- Stakeholder buy-in came from showing the capability map before announcing the shortlist. People needed to see that no capability was being lost, only consolidated.
- The handover from outgoing agencies took longer than planned. Build an extra two weeks into migration timelines.
- Scoring agencies against a KPI scorecard from day one, rather than waiting for the first QBR, accelerated accountability.
For readers considering a similar move, maintaining brand control during agency partnerships is a practical next step before briefing any new roster partner.
Legal and compliance considerations when contracting multiple agencies in the UK
Contracting multiple agencies simultaneously in the UK market creates specific legal and compliance obligations that procurement teams must address before any roster goes live.
Data protection: Each agency on your roster that handles personal data must sign a Data Processing Agreement (DPA) compliant with the UK GDPR and the Data Protection Act 2018. This applies to agencies running email campaigns, managing CRM data, or producing targeted advertising. The DPA must specify the lawful basis for processing, data retention periods, and sub-processor obligations.
Intellectual property: SOWs must explicitly assign IP ownership. The default position under UK copyright law is that the creator owns the work unless the contract states otherwise. For brand assets, campaign creative, and video production, the SOW should transfer full IP to the client on payment of the final invoice.
IR35 and employment status: If any roster partner uses freelancers to deliver your work, and those freelancers work primarily for your organisation through that agency, IR35 rules may apply. Procurement should request a confirmation of employment status compliance from each agency at onboarding.
Conflicts of interest: Where a roster includes agencies that also work for direct competitors, a conflict of interest clause in the SOW protects confidential briefs and campaign data. This is standard practice in UK agency contracts and should not be negotiated away.
Procurement thresholds: Public sector organisations and many large private sector businesses operate internal procurement thresholds above which a formal tender or mini-competition is required. Know your organisation’s thresholds before appointing any agency, and document the selection rationale for audit purposes.
Insurance: Require professional indemnity insurance (minimum £1 million, though £2 million is standard for larger engagements) and public liability insurance from every roster partner. Collect certificates at onboarding and at annual renewal.
The part of roster work most teams get wrong
Most marketing teams approach roster rationalisation as a procurement exercise. They focus on cost, supplier count, and contract terms. Those things matter. But the harder problem is governance: who owns the roster after the contracts are signed?
We see this consistently. A client invests three months in a thorough shortlisting process, appoints four strong agencies, writes solid SOWs, and then assigns roster oversight to whoever has capacity at the time. Within a year, the QBRs have slipped, the scorecard has not been updated, and two agencies are doing work that overlaps with a third. The roster has drifted back toward the problem it was designed to solve.
The fix is not more process. It is a named person with a clear mandate and the authority to act on performance data. In smaller organisations, that person is often the Marketing Manager. In larger ones, it is a dedicated roster operations owner with a direct line to the Procurement Business Partner.
When to tackle this in-house: if your roster has fewer than five agencies and your internal team has capacity for monthly alignment calls and quarterly scoring, you can manage it without external support.
When to bring in a specialist: if you are consolidating from more than six agencies, managing a regulated sector, or running a roster across multiple markets, the governance design and transition management benefit from an experienced partner.
