About Us

Madsen Advisory

Madsen Advisory’s ethos is about giving frank, honest and pertinent advice. Whether helping our clients to expand and develop their management teams or execute a sale or acquisition.

We have been established since 2002, initially as a specialist search consultancy, before becoming one of the leading brokerages of marketing communication agencies, in particular public relations and public affairs consultancies, in the UK .

We help the management and shareholders of independent marketing communication consultancies to prepare their businesses for sale, particularly by helping to identify and maximise the value in advance of a sale, identifying the buyers, helping them to manage the process of the sale and negotiating to a satisfactory solution for all parties.

While not all of our eighty plus deals are in the public domain, as some of the transactions must necessarily remain confidential, our Past Transactions shows some of the completed deals.

We are both entrepreneurial and creative in our approach to each assignment and this coupled with the ability to think laterally has ensured that we have established long term successful relationships throughout the marketing communications industry.


No good business can exist without an ethical approach in the manner in which it does business. Whilst pushing the limits on behalf of our clients we never stray beyond the boundaries of personal integrity and our strict ethical guidelines.
