TCS: Expanding Aviva Partnership to Cover 6.5m Policies

Tata Consultancy Services has announced a significant expansion of its partnership with Aviva, extending end-to-end policy administration services to cover more than 6.5 million policies.

The additional portfolio will be managed by TCS' FCA-regulated subsidiary, Diligenta UK, on behalf of the UK's leading insurance, wealth and retirement provider.

Aviva’s strategic portfolio expansion

The expanded agreement sees Aviva entrusting TCS with an additional life insurance portfolio.

The move builds on a long-standing relationship between the two organisations and centres on delivering customer-centric digitisation aligned with New Consumer Duty Principles.

This includes self-service capabilities for policyholders, digitally powered service delivery centres and a simplified technology landscape.

Vivekanand (Vivek) Rangopal, President of BFSI Products & Platforms at TCS, says: "Our enduring partnership with Aviva, established on mutual trust and commitment over many years, has continually strengthened and delivered a better experience for customers."

"Aviva's ongoing trust in our services and their decision to entrust us with additional portfolios demonstrates the depth of our collaboration."

"We remain dedicated to delivering an exceptional experience for Aviva and its customers."

Digital platform migration

Diligenta has successfully migrated several million policies to TCS BaNCS, its advanced digital platform.

The platform supports conversational interfaces to guide users through business journeys and features a product configurator that reduces time-to-market for new offerings to days rather than months.

TCS BaNCS for Life Insurance and Pension offers domain APIs that simplify ecosystem connectivity and enable interoperability across channels and business lines.

The platform's one ecosystem philosophy enables carriers to build advanced digital portals with first-point resolution, straight-through processing and risk control features built in.

This enables carriers to provide policyholders with enhanced self-service capabilities, along with contextualised communications and insights.

UK market commitment

The TCS-Aviva partnership underscores TCS' position as a trusted technology partner for leading UK businesses.

With a 50-year presence in the country, TCS works with over 200 of Britain's top brands and recently committed to creating 5,000 new jobs across the UK in the next three years.

The organisation holds a leadership position in software and IT services and has been ranked the number one IT service provider for customer satisfaction in the UK in an independent survey of CIOs from the largest IT spending organisations.

Aviva operates across the UK, Ireland and Canada, with international investments in India and China.

The company helps 25.2 million customers and manages total group assets under management of £419bn (US$561.1bn) as of 30 June 2025.

Its estimated Solvency II shareholder capital surplus stood at £7bn (US$9.38bn) as of September 2025.

Aviva: Insurance and climate leader 

Aviva has positioned itself as a leader in climate adaptation strategies through its 2025 Building Future Communities report.

The report reveals that eight million UK properties could face flooding risk by 2050, with 1.4 million vulnerable to subsidence.

Jason Storah, CEO of Aviva UK & Ireland General Insurance, said at the time: "It is increasingly clear that, while we should double down on efforts to reduce climate change, there is equally an urgent imperative to be climate-ready."

Aviva is pledging more than £80m (US$105.8m) towards nature-based solution projects that capture carbon, contribute to flood resilience and restore natural habitats.
