Welcome to Costello Lettings


Dear Landlords and Tenants,

Costello Lettings office
Welcome to our website which explains how we work for both tenants and landlords, what inspires us and how we stand out from the crowd. We let and manage a portfolio of property worth £20 million, our own portfolio topping £4.2 million so you can be confident that we know what we’re doing! We‘re an independent family firm and that’s our strength – we’re small enough to care but large enough to deliver and pride ourselves in the strong relationships we forge with our clients.

We specialise in offering high quality homes in Dorset’s towns and villages and ensure a bespoke service to every client. We pride ourselves in the fact that the majority of our work is through word of mouth and we offer a personal service that is accountable, professional and reliable.

We appreciate that renting out your property is a huge step and ensure that our strict vetting procedures and attention to detail ensure that you can let us get on with the job. We empathise with our tenants’ needs and aspirations, ensuring that they move into the home best suited to their circumstances and character.

We have a passion for property and people but are practical as well! We solve your problems and give you sensible solutions regarding maintenance and throughout the years we have built up a trustworthy team of tradespeople. Tenants and landlords have the reassurance of a 24 hour emergency helpline should disaster strike.

With full management at ten per cent we undercut the competition considerably but do not stint on the things that really matter – your home.

If you would like to find out more please get in touch.

Best wishes,





Small enough to care, Big enough to deliver
