Nationwide Accident Repairs has secured the renewal of two major insurer contracts.
The continued two-year agreements with Hastings Direct and Zurich Insurance are worth a combined total of £30m in sales annually.
In addition, Nationwide has agreed a short term arrangement with Aviva for the early part of 2013, worth £3m, after its previous partner went into administration.
Michael Wilmshurst, chief executive, said: "We are delighted to continue our excellent relationship with both Hastings Direct and Zurich Insurance where our integrated offering provides high service levels, good value and quality of repair.
"The additional work that we will be undertaking for Aviva is also pleasing and is testament to the strength of our existing relationship as well as the prompt and proactive approach of our teams to deliver continuity of their customer services following the administration of one of their key suppliers."
