About Castledene

The Casteldene group of companies was started by John Paul in 2008 as a means of managing John’s personal portfolio. The company grew extremely quickly, managing over 200 homes within its first two years.  John Paul has amassed a wealth of knowledge on the UK property market, particularly the North East of England. John’s expertise resulted in him being appointed to the board of ARLA (Association of Residential Lettings Agents) in 2016, a post John continues to fulfil, representing the North of England.

Through both organic growth and acquisition of competing businesses, the Castledene Group of Companies manages over 2,000 houses, with that number rising every year.

The Castledene Group of companies currently comprises seven residential sales and lettings branches in the North East of England under the brands of Castledene Sales and Lettings, Hegartys Estate Agents and Gordon Lamb Estate Agents. The Castledene Group of companies also includes Castledene Property Consultants, which has sourced a number of residential and commercial properties for individual buy-to-let landlords through to institutional investors.

In recent years, Castledene has experienced great success on the national stage, winning the Sunday Times best letting agent in the United Kingdom in 2014, beating over 5,000 other lettings agents to the award.


Castledene places a great emphasis on staff training and development and considers these to be substantial contributors to the group’s increased growth and success. The Castledene Group was the first, and remains to this day, the only estate/ letting agent in the UK to be awarded the Investors in People Gold accreditation, attaining the accreditation on its first attempt.


The Castledene companies are prided on their quality, and score exceptionally well on property industry review websites. All 6 estate and letting agency branches are rated number 1 in their respective locations by customers on allAgents.co.uk, the largest property industry review website in the United Kingdom.

The wealth of experience of the Castledene Group will provide significant resource to Rent to Own via the sourcing of properties for landlords and investors, the sourcing of Tenant Buyers, the management of lettings and the guidance of all parties through to completion of the sale and purchase of each property via the rent to own strategy.
