The Broker Investment Group (TBIG) has completed its fifth acquisition of 2025 with the purchase of KSL Thomas & Co Ltd, a well-established insurance broker based in Romford, Essex.

KSL Thomas manages approximately £2 million in Gross Written Premium (GWP) and specialises primarily in commercial insurance. The firm has been serving clients in Essex and across the UK for over 63 years.

Following completion, the KSL Thomas brand, team, and premises will remain unchanged. The business will continue to be led by Director Rex Thomas, who will be supported by TBIG’s centralised support team covering marketing, sales, compliance, accounts, and acquisition sourcing.

This acquisition acts as a strategic addition into Callaway’s Insurance, a TBIG investment in March 2024 based in Chelmsford, further strengthening TBIG’s presence in Essex, with total regional GWP now exceeding £10 million.

Simon Lewer, Regional Managing Director, is overseeing the integration of KSL Thomas into Callaway’s Insurance and will be responsible for the continued growth of both businesses, alongside exploring potential future acquisitions in the area.

Rex Thomas, Director and Owner of KSL Insurance, said:
“After careful consideration, we chose TBIG as our preferred partner because they share our ambition for local growth and team development. We are excited to expand with the support of TBIG and look forward to leveraging the buying power and partnerships of a larger group. This is a true partnership, and I am confident that together we will grow the business.”

Simon Lewer, Regional Director, Callaway’s Insurance (part of TBIG), commented:
“I’m delighted to welcome Rex and his team to Callaway’s and TBIG. KSL Thomas is a high-quality business, and I am confident they will integrate seamlessly into the wider TBIG group. Our mission is to invest in, support, and develop regional brokers through sustainable growth and partnership. KSL aligns perfectly with this vision, and I look forward to working closely with their team.”

Dave Clapp, CEO of The Broker Investment Group, concludes:

“TBIG has a strong pipeline of deals for the remainder of the year. Despite a soft market, we remain on track to achieve our ambitious yet achievable GWP targets through organic growth and carefully selected strategic acquisitions into our regional powerhouses.”
