The deal completed on 27 September and brings the combined assets under administration and management for Thorntons Wealth Management and Thorntons Investments to close to £1 billion.

One additional benefit of the increased scale of the enlarged Thorntons Wealth business will be a reduction in service costs for the vast majority of Robson Macintosh’s clients.

In time the branding of the acquired business will be aligned with Thorntons Wealth Management.

Thorntons Wealth Management CEO Stephen Webster said: “We were drawn to Robson Macintosh due to its stellar reputation for service and quality financial advice.

“We see no need to change any of that other than to invest in processes to make the client experience even better.

“We’re always on the lookout for other attractive acquisition opportunities to grow our business with like-minded firms to widen our overall proposition and better serve everyone’s investment and financial planning needs.”
