At NIG, we’re experts at Commercial Insurance.

We specialise entirely in commercial insurance – and nothing else. So our highly experienced underwriting teams are completely focused on identifying and understanding the continually challenging risks faced by small and medium enterprises throughout the UK.

But what really sets us apart is our partnership approach. We work exclusively through a network of over 2,200 insurance brokers, collaborating closely with these partners to deliver the cover, services and support you’d expect from a national organisation at a local level.


The National Insurance and Guarantee Corporation (NIG) is a wholly owned subsidiary of Direct Line Group and was originally incorporated 8th October 1894 to provide personal and commercial insurance throughout the UK.

NIG was part of the Churchill group of companies acquired by The Royal Bank of Scotland Group on 1st September 2003.

NIG sells its products exclusively through independent brokers operating across the UK. Following a strategic review NIG withdrew from the personal lines market in August 2010 focusing its commitment in delivering commercial insurance through exclusive distribution via the broker.
