Welcome to Hellas-Helvetia


Hellas-Helvetia Limited has been established since 1971 and specialises in residential sales, lettings, investment properties and property management in Bayswater, Notting Hill, Holland Park, St John's Wood, Maida Vale, Kensington and the surrounding areas.

We offer a full, comprehensive and professional service to buyers, sellers, landlords and tenants, with an established local and international clientele who have been with us for many years. We are members of the National Association of Estate Agents, the Association of Residential Letting Agents and the Ombudsman for Estate Agents and the London Rental Standard, and offer our clients a high and professional quality of service with the expert knowledge gained from four decades of experience in this area. Through our links with other agents we can source properties all over London or offer your property to them at no extra cost to you.

Hellas-Helvetia is open six days a week, Monday to Friday 9:30am – 6:00pm, and on Saturdays by appointment only.  We have over half a century’s experience providing accommodation for a wide variety of applicants from professional couples to students. We manage many of the flats we let and offer an excellent level of service over the period of the tenancy. All deposits are protected with the Tenancy Deposit Scheme (TDS) and a full inventory is carried out prior to a tenant moving in.

Our office is at 80 Queensway, London, W2 3RL, in the heart of Bayswater. 



Hellas-Helvetia is an independent family-owned Estate Agent that has been selling properties in Bayswater and the surrounding areas since 1971. We have an unrivalled knowledge of the area and can help find you the property that suits your needs, be it for a family home, a pied-a-terre or an investment. If you are selling, we have an established clientele of cash buyers looking for investment opportunities.


Hellas-Helvetia will find tenants for your property, take full references and prepare an Assured Shorthold Tenancy Agreement.  The security deposit and first month’s rent will be paid over to the landlord less our commission fees, after which the landlord will be responsible for the management of the property.


Hellas-Helvetia’s Property Management Department has over half a century of experience in property management and has an established local and international clientele. We offer landlords a high quality personalised service.  We can take care of all the landlord’s duties including preparing Tenancy Agreements and legally registering the security deposit, collecting rent, pursuing any arrears, handling tenancy renewals and rent reviews. We also make sure that maintenance and any repairs are carried out efficiently and are fully conversant with all legislation that may affect your property like gas and electrical safety checks and certification. All funds are held in our Clients Account and we are members of the Propertymark client money protection scheme.
