The deal is worth £200m of capacity over five years and was completed by Matthew Schofield, chief underwriting officer for Q Underwriting’s MGU team.
Schofield said: “To renew our partnership with such a prestigious partner as Aviva, and to welcome Ergo, all in the first quarter of 2021 is an exceptional achievement for the business.
“To do this at a time where many in the market are experiencing challenges with capacity makes it more impressive.”
Bernard Mageean, CEO of Q Underwriting, said: “Securing this key binder, with a long-term commitment from Aviva is a great endorsement for Q Underwriting and the whole team.
“To close these deals at a time where many in the market are experiencing challenges with capacity demonstrates our strength and proposition. We are a valuable, robust partner for insurers and brokers alike.”
