Commercial broker handling £2m GWP acquired after 63 years

The Broker Investment Group (TBIG) has completed its fifth acquisition of 2025 with the purchase of KSL Thomas and Co.

KSL Thomas, which specialises primarily in commercial insurance, has been serving clients in Essex and across the UK for over 63 years.

It manages approximately £2m in gross written premium (GWP).

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.

Thomas 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.”

Expansion

This acquisition acts as a strategic addition into Chelmsford-based Callaway’s Insurance, a firm TBIG invested in last year.

This will help TBIG further strengthen its presence in Essex, with total regional GWP now exceeding £10m.

Simon Lewer, regional managing director at Callaway’s Insurance, is overseeing the integration of KSL Thomas and will be responsible for the continued growth of both businesses, alongside exploring potential future acquisitions in the area.

Lewer said: “I’m delighted to welcome Thomas 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 its team.”
