The Broker Investment Group (TBIG) has announced its fifth acquisition of 2025 with the purchase of KSL Thomas & Co Ltd, a well-established insurance brokerage based in Romford, Essex.
KSL Thomas, which oversees approximately £2 million in gross written premium (GWP), specialises in commercial insurance and has been serving clients across Essex and the UK for over 63 years. The firm will continue operating under its existing brand, retaining its current team and premises. Director Rex Thomas will remain at the helm, supported by TBIG’s centralised services team, which provides expertise in marketing, sales, compliance, accounts, and acquisition sourcing.
This acquisition marks TBIG’s latest move to strengthen its footprint in Essex, following its 2024 purchase of Chelmsford-based Callaway & Sons Insurance Consultants. KSL Thomas will now operate alongside Callaway Insurance under the leadership of regional managing director Simon Lewer, who will oversee the integration and strategic growth of both businesses in the region.
Commenting on the acquisition, Lewer said: “KSL Thomas is a high-quality business that fits seamlessly within the TBIG group. Our mission is to invest in, support, and develop regional brokers through sustainable growth and true partnership. KSL aligns perfectly with this vision.”
The deal is part of TBIG’s ongoing investment strategy, which has seen the group complete a string of acquisitions across the UK. In 2024, TBIG acquired a 49% stake in both Jenkinson Insurance and Penk Insurance in a transaction with the Jenkinson family. Additionally, the group secured full ownership of Bedford-based Bullerwell Insurance, which manages around £12 million GWP, following the purchase of its remaining shares. Bullerwell is now fully integrated into TBIG’s operations.
Over the past 12 months, TBIG has executed 10 investments, maintaining the deal momentum it established in 2022. With a combined £60 million in GWP added through organic growth and acquisitions, the group remains on track to reach its £250 million GWP target by the end of 2024.
