“Each one fits well with our business and culture and we look forward to continuing to give David, Clive and Charles’ clients the quality, face-to-face financial planning they are used to.
“Given we now have a proven track record, we are seeing increasing numbers of firms approaching us directly and we expect to complete on further acquisitions before the end of the year.”
These deals bring the number of firms acquired by the national advice business to 11.
