Here are Sri Lankan life insurers widely cited for strong customer service (based on recent awards, consumer polls and company/industry reports from 2023–2025):

• Ceylinco Life — frequently tops consumer polls and “people’s choice” awards (SLIM Kantar Peoples Awards, World Finance recognitions). (ceylincolife.com)
• Sri Lanka Insurance (SLIC Life) — repeatedly ranked a “Most Loved” life‑insurance brand in LMD surveys and praised for claim payouts/brand trust. (dailynews.lk)
• AIA Sri Lanka — recognised by international award bodies for product/service quality and customer experience initiatives. (aialife.com.lk)
• Union Assurance — noted for digital customer‑service innovations (fast digital underwriting/medical reports) and recent “best digital life insurer” / industry awards. (newswire.lk)
• HNB Assurance — strong bancassurance network, multiple industry awards and recognitions for service and distribution. (hnbassurance.com)

Notes on choosing the “best” for you

• “Best customer service” depends on what you value (fast claims, easy digital access, strong branch/agent support, low premiums). Awards and polls indicate general reputation but may not reflect your personal needs.
• Useful metrics to check when comparing companies: recent claims settlement speed/ratio, online/app ratings, complaint records (Insurance Regulatory Authority/Securities & Exchange Commission notices), and recent customer surveys (SLIM Kantar, LMD). The items above are drawn from awards & surveys published in 2023–2025. (ceylincolife.com)

If you want, I can:

• compare 2–3 of these insurers side‑by‑side (claims policy, digital tools, branches, premiums) or
• pull up recent customer‑complaint / regulator data for any specific insurer listed.
