Cheshire Data Systems' brokers and intermediaries can now electronically access Legal & General's Rainbow Plan and Rainbow Select Plus.
The buildings and contents products benefit from automatic underwriting, premium guarantees, and full policy documentation.
The insurer's managing director, John Castagno, said: "Legal & General is committed to transacting business electronically. It enables intermediaries to offer a seamless and instantaneous service."
L&G made the products available to all Cheshire brokers after a two-month trial with two of them. During the test, the firms issued over 380 policies.
