The Budget Group recently acquired J&M Insurance in Scunthorpe - its 85th branch - as part of its strategy of obtaining national coverage via strategic high street locations.
Budget believes it has successsfully raised its high street profile in the last year by acquiring four new branches and several thousand new policies.
Spokesman Paul Cosh said: "As insurance trading on the high street began to slow down for some companies, Budget challenged this trend. Our strategy is to be available to our customers through whatever channel they prefer, whether this be a contact centre, branch or the internet.
"Many customers still like to conduct business face to face and our retail network enables them to do this."
