Agentic AI Vendor Evaluation: A Scorecard for UK Contact Centre Procurement Teams

Arkadas Kilic

Rel8 CX is an AWS Advanced Partner that builds autonomous AI agents for regulated UK contact centres. We've been on both sides of procurement conversations, and the same pattern repeats: procurement teams ask the wrong questions, vendors answer the wrong questions, and the contact centre ends up with a proof of concept that never reaches production.

This post gives you the scorecard we'd want you to use when evaluating us, or anyone else.


Why Most AI Vendor Evaluations Fail

Most RFPs for contact centre AI are written by people who've never deployed one. They ask about "AI capabilities" and "integration flexibility" and "scalability roadmap." Vendors answer with slide decks, demo environments, and reference customers who signed NDAs.

The result is a procurement process that selects for the best presenter, not the best builder.

The questions that actually matter are operational: How long until this is live? Who owns compliance? What happens when the agent fails? What does your AWS architecture look like in production?

Here's how to structure your evaluation so you get real answers.


The Scorecard: 7 Evaluation Dimensions

Score each vendor 1 to 5 on each dimension. Weight the dimensions according to your organisation's priorities. A regulated financial services contact centre should weight compliance and architecture heavily. A high-volume insurance operation should weight time-to-production and containment rates.

Dimension 1: Production Track Record

What you're testing: Can this vendor ship working agents into live contact centre environments, or do they build prototypes? Questions to ask: Red flags: What good looks like: A vendor who can say "we went live in 5 weeks for a UK debt collections firm and hit 41% containment in week one" is telling you something real. Round numbers and vague timeframes are not. Score 5 if: The vendor has 3 or more production agents live in UK contact centres with verifiable outcome metrics. Score 1 if: The vendor's "production" references are internal tools or demo environments.

Dimension 2: Regulatory and Compliance Architecture

What you're testing: Is compliance an afterthought bolted on at the end, or is it built into the architecture from day one?

For UK contact centres, the regulatory landscape is specific and demanding:

Questions to ask: Red flags: Score 5 if: Compliance controls are demonstrable in architecture diagrams, not just stated in a slide. The vendor can walk through a vulnerable customer scenario end to end.

Dimension 3: AWS Architecture Depth

What you're testing: Is the vendor a genuine AWS builder or a third-party tool reseller wrapped in AWS branding?

This matters for three reasons. First, AWS-native architecture means your data stays in your AWS environment, not a vendor's SaaS platform. Second, AWS-native builds integrate directly with Amazon Connect, your existing contact centre infrastructure, without middleware that creates latency and failure points. Third, AWS-native vendors can leverage services like Amazon Bedrock, Amazon Transcribe, Amazon Lex, and AWS Lambda in ways that reduce cost and increase reliability compared to third-party AI platforms.

Questions to ask: AWS partnership tiers (for context):
TierWhat it means
AWS Partner (entry)Registered, minimal requirements
AWS Select PartnerSome validated experience, basic requirements met
AWS Advanced PartnerDemonstrated delivery capability, customer references, staff certifications
AWS Premier PartnerHighest tier, significant delivery volume and specialisation

An AWS Advanced Partner has met specific requirements around certified staff, customer references, and delivery capability. It is not a marketing badge.

Red flags: Score 5 if: The vendor deploys into your AWS account, uses AWS-native services throughout the stack, and can show an architecture diagram with specific service names.

Dimension 4: Time to Production

What you're testing: How long until this agent is handling real customer interactions?

This is where most vendors lose points. The industry average for enterprise AI deployments is 6 to 18 months. Most of that time is not technical. It is scoping, stakeholder alignment, procurement cycles, and change management. A vendor who has done this before knows how to compress the timeline.

Benchmark: A production-ready agentic AI deployment for a UK contact centre should take 4 to 6 weeks from kick-off to live if the vendor has done it before and the contact centre has a functioning Amazon Connect environment. Questions to ask: What a realistic 4 to 6 week timeline looks like:
WeekActivities
1Discovery, call flow mapping, integration scoping, AWS environment access
2Agent architecture design, intent taxonomy, compliance review
3Core agent build, Amazon Connect integration, test environment
4UAT, edge case handling, vulnerability scenario testing
5Soft launch with live traffic at 10%, monitoring, iteration
6Full production rollout, containment baseline established
Red flags: Score 5 if: The vendor has a documented deployment methodology with a week-by-week plan and references who confirm the timeline was met.

Dimension 5: Containment and Outcome Metrics

What you're testing: Does this vendor measure the right things, and do their numbers hold up?

Containment rate is the percentage of interactions the AI agent resolves without transferring to a human agent. It is the primary operational metric for contact centre AI. But containment rate alone is not enough. A 70% containment rate that generates FCA complaints is worse than a 40% containment rate with zero regulatory issues.

The metrics that matter:
MetricWhat it measuresBenchmark
Containment rate% of interactions resolved by AI35% to 55% at go-live for voice; 60%+ for digital
Escalation accuracy% of escalations that genuinely needed a humanAbove 90%
Average handle time (AI)Time per AI-handled interactionDepends on use case, ask for actuals
Customer satisfaction (CSAT)Post-interaction satisfaction for AI-handled callsShould be within 5 points of human-handled baseline
Complaint rateFCA reportable complaints generated by AI interactionsShould be lower than human baseline
Vulnerable customer escalation rate% of interactions flagged and escalated for vulnerabilityBenchmark against your current human rate
Questions to ask: Red flags: Score 5 if: The vendor has production data on all six metrics above and can explain what drove the numbers.

Dimension 6: Ongoing Operations and Ownership Model

What you're testing: What happens after go-live? Who owns the agent's performance?

This is where many contact centres get burned. The vendor delivers a working agent, hands over documentation, and disappears. The contact centre team doesn't have the skills to tune the agent, handle edge cases, or adapt it when call drivers change. Performance degrades. The project is declared a failure.

Questions to ask: Two models to evaluate:
ModelWhat it meansBest for
Build and transferVendor builds, trains your team, exitsOrganisations with internal AI engineering capability
Managed operationsVendor runs the agent ongoing, you own the outcomesOrganisations without internal AI ops capability

Neither model is inherently better. But you need to know which one you're buying before you sign.

Red flags: Score 5 if: The vendor has a defined operational model, clear SLAs, and references who have been running production agents for 12 or more months.

Dimension 7: Team Composition and Delivery Model

What you're testing: Who actually builds this? Are they practitioners or account managers?

The contact centre AI market is full of consultancies that sell AI transformation and deliver PowerPoint decks. The tell is the team they put on your project. If the people who present in the sales process are not the people who build the system, you are buying a brokered service.

Questions to ask: What good looks like: The vendor can name the specific engineers who will work on your project. Those engineers have deployed production agents before. They hold relevant AWS certifications. They are not subcontracted. Red flags: Score 5 if: You have met the engineers who will build your agent before signing. They can answer technical questions directly.

The Scorecard Summary

A vendor scoring below 3.0 weighted average is a risk. A vendor scoring above 4.0 on compliance and production track record is worth serious consideration regardless of their total.


Questions That Reveal Everything

If you only have 30 minutes with a vendor, ask these five questions and listen carefully:

1. "Show me a production deployment timeline from contract to live call." Not a proposed timeline. An actual one.

2. "Walk me through how your agent handles a customer who says they're struggling financially." This tests vulnerability handling, Consumer Duty awareness, and CONC compliance simultaneously.

3. "Who specifically will be building our agent? Can we meet them today?" This separates practitioners from sales organisations.

4. "What went wrong on your last deployment and how did you fix it?" Every real deployment has problems. Vendors who say everything went smoothly are lying or selling you a demo.

5. "Where does our customer data sit and who has access to it?" The answer should be: in your AWS account, with access controlled by your IAM policies.


A Note on Proof of Concepts

Many vendors will offer a free or low-cost POC to get a foot in the door. Be cautious. A POC that runs in a vendor's demo environment, uses synthetic data, and has no compliance controls is not evidence of production capability. It is a sales tool.

If you run a POC, insist that it:

A vendor who can't commit to these POC conditions is not ready to build your production system.


How Rel8 CX Scores on This Scorecard

We build production agentic AI agents for regulated UK contact centres. We are an AWS Advanced Partner. We deploy in 4 to 6 weeks. Our engineers are the people who present in the sales process. Compliance is built into our architecture from day one, not added at the end.

We've deployed into debt collections, insurance, and financial services environments where FCA compliance and Consumer Duty obligations are not optional. We know what vulnerable customer handling looks like in a production agent. We know what CONC-compliant collections AI sounds like on a live call.

We don't claim to score 5 on every dimension for every contact centre. We'll tell you where we're the right fit and where we're not.
