The Employers' Liability Tracing Office (ELTO) is an independent industry body. Its voluntary members comprise of insurers who provide Employers' Liability (EL) insurance and have chosen membership of ELTO as the means by which they will publish data on Employers' Liability policies underwritten by them in compliance with new Financial Services Authority (FSA) regulations.

ELTO’s aim is to assist the insurance industry to meet its obligations by aiding those who have suffered injury or disease in the workplace to effectively and efficiently trace the relevant insurer.

Since 1999, the voluntary EL Code of Practice, operated by ABI-member insurers and the associated tracing service administered by the ABI on their behalf, has assisted more than 20,000 claimants. Under this arrangement, insurers were given details by the claimant or representative and were asked to search their records to the best of their ability, but this did not provide an immediate response.

Though trace success rates consistently improved, the numbers were lower than claimants and insurers would wish to see. ELTO is designed to bring about an improvement to the service provided to customers by centralising these trace searches.
