A leading energy provider in the UK with 10,000+ household connections set out to transform its customer support experience by deploying AI-powered chatbots and voicebots. With a growing customer base, inquiries spanned billing issues, prepayment meter support, outage updates, and general utility service FAQs. Traditional support channels struggled with long wait times and inconsistent service quality.

The company needed a solution that could deliver fast, reliable, and personalized customer support across both digital and voice channels—while maintaining scalability, accuracy, and cost efficiency.

RootQuotient designed and implemented a production-grade Generative AI chatbot and voicebot system using AWS services, enabling 24/7 automated support with domain-specific knowledge grounding and real-time system integrations.

Customer Challenge

The UK-based energy provider faced several operational challenges that negatively impacted customer satisfaction:

1. High call volumes and long wait times

Support agents were frequently overwhelmed during peak hours, resulting in delays.

2. Growing volume of complex FAQs

Queries covered prepayment issues, billing discrepancies, meter readings, and general utility support.

3. Fragmented knowledge sources

Key information was distributed across internal systems, policy documents, and legacy tools—making retrieval difficult for agents.

4. High operational support costs

Scaling the support team was expensive and inefficient, especially with seasonal demand spikes.

5. Inconsistent customer experience

Customers received varied responses depending on the agent’s knowledge and availability.

The provider needed an intelligent, scalable GenAI solution that unified information, automated responses, and reduced agent workload.

Solution Delivered by RootQuotient

RootQuotient deployed a multi-channel Generative AI Customer Support System leveraging Amazon Bedrock, Retrieval-Augmented Generation (RAG), and AWS’s serverless architecture.
