Meet the lettings team

Our lettings team works hard to ensure all our rental properties get the exposure they need. Unlike other agents, we do not work in competition with each other but as a team to show tenants the most suitable properties. We cover a wide area of West London including Notting Hill, Kensington, North Kensington, Bayswater, Marylebone, Earls Court and Chelsea for both long and short lets.

Liz studied modern languages and business at university but always had a passion for architecture and interior design. Now with over 30 years in agency Liz's reputation in the industry is undisputed. Our business has been built on the back of our clients' respect for her integrity and straightforward approach to everything we do as a brand.

I'm a frustrated architect at heart and I never tire of property. I like to build long-term relationships with my clients; nothing is more rewarding than knowing they completely trust me with their biggest investment.

Annabel Kastelic - Lettings Director

Annabel Kastelic

Director of Lettings


Annabel was born and raised in London and has experienced its vibrancy and culture first hand. After graduating from the University of Portsmouth and obtaining a degree in Sociology, Annabel threw herself straight into the property industry starting at a large corporate estate agency and specialised in short lets during her time. 6 years later she progressed onto Mountgrange to offer a more personable and specialised service for landlords, bringing with her an array of experience particularly within the short let market.

I enjoy working in a tightknit team where customer service is the focus, we are able to work together efficiently and seamlessly to achieve the best results for our landlords and tenants alike.

Working with you guys is really low hassle, and you’re always very responsive to my questions! For a first-timer like me, it’s really great to have the support I’ve had from you.

Laura has been instrumental in maintaining a high level of efficiency in our Accounts Department.

One might think that doing accounts is the least exciting role; however, at Mountgrange I have the autonomy to add my inimitable brand of diligence and creativity to the job.

Bethany Brown

I couldn’t be more grateful to have kick started my property career with Mountgrange Heritage. The team here are dynamic but welcoming and supportive at the same time. Meeting new people and building new relationships every day is an absolute joy.

Mountgrange Heritage have been successfully letting my small flat for over twenty years now. They have been a pleasure to work with; they have been efficient and have taken time and trouble when details have needed sorting out.

Michelle Flowers

Senior Associate


Michelle was born and raised in Johannesburg, South Africa and having grown up in a big city London was an easy choice. Experiencing a move across continents and navigating the process of the property market in unfamiliar territory she is truly able to empathise with the rental process for tenants. Michelle felt that with her background being in sales and customer service she could be a great help to others doing the same and worked her way up through the ranks at a corporate agency before she found herself at Mountgrange. Michelle likes to spend time with family and friends and going for long walks in her spare time.

From the moment I walked into the office I immediately felt part of the team! I am so grateful to be part of the Mountgrange Heritage family and have the opportunity to learn from the best in the business and continue to grow my knowledge within the industry.

He hails from Somerset and fully appreciates the value of rural living but after several years of study, travel and helping expand a family real estate portfolio, he felt his future interests lay in the capital and all it has to offer.

Working for an independent, client focused, personable agency who exclusively operate in some of London’s most notable postcodes is a real treat
