About Jane Gardner

Jane Gardner is a distinguished professional with an impressive career spanning decades in the property industry. Beginning her journey as a sales negotiator for Connells Estate Agents in the 1980s, she has since demonstrated a remarkable trajectory, having worked in diverse settings including independent, franchised, and corporate estate agencies, as well as founding and leading several successful agency businesses.

In 2002, Jane founded Sewell & Gardner in Hertfordshire, growing it into a notable three-branch agency. Her hard work and dedication to excellence were recognised when the agency won the prestigious Sunday Times Lettings Agency of the Year Trophy in 2013. In a testament to her success, Sewell & Gardner was acquired by Countrywide plc at the close of 2014 for a record amount.

Jane is interviewed for Propertymark Professional Magazine

All new clients will receive a ZOOM consultation appointment in order to discuss their particular requirements and for us to get a feel for the business, whilst ascertaining if we do indeed have the tools to assist you.

Our particular approach is based heavily upon the need for exceptional customer service and commitment from senior management, fully engaging all members of staff from part-time negotiators, accounts and administrative teams, through to property managers, lettings and sales consultants, and branch or regional managers. Without your full commitment to the ideas and plans we make, I’m afraid your investment with us will be ineffective.


After your initial consultation, you will receive a brief overview of our meeting and the main points raised, along with our structure for moving forward and our hourly, daily or monthly rates as a guideline for further discussion.  Jane’s time is limited, and she is only available to work with one client at a time for consulting; there may be a waiting list.

  • Jane’s daily price – in person £1,075 (10am to 5pm)
  • Half-day rate – in person £550 (4 hours)
  • Hourly zoom rate – £125+VAT – Book Here
