The Portman Estate

The Portman Estate is a forward thinking property company with an enduring heritage and a commitment to promoting and protecting the long-term success of Marylebone and London's West End.

The Portman Estate is proud to be the first estate to be awarded B Corp Certification. This certification is a reflection of the Estate’s 500-year stewardship of Marylebone, which has centred on taking a long-term, forward-looking view for the future benefit of all stakeholders, customers and partners. 
 
We recognise our responsibility to provide a high quality, sustainable environment while seeking to safeguard our community, manage responsively and evolve our portfolio for the benefit of all. We aim to do this with a Clean Heart and a Cheerful Spirit, as the family motto directs.
