5/5
Genuinely such a swift and easy process with Greenhill. We met with many estate agents but felt that Julia understood all our needs and was so knowledgable about our type of property and the area. We were informed every step of the way and we were able to contact them whenever we needed to. Would definitely recommend Greenhill to anyone selling their home.
Thank you for your lovely review

Everything you could want from an estate agent and more! Super communicative, really down to earth and honest team who go the extra mile for their clients. I’ve hopefully found a home through them that I will be living in for a long time to come however, I wouldn’t hesitate to use them on the next time around, or refer them to friends!PositiveResponsiveness, Quality, Professionalism, Value

5/5
Can’t rate Greenhill Estates highly enough. I don’t live near the property I was selling and they arranged all viewings, collecting keys from the tenants whenever suited them and always keeping me updated after every viewing. They even went above and beyond, liaising with tradesmen to let them into the property on my behalf. Highly recommend.
Thank you so much for your review, it’s always a pleasure for us to go the extra mile for our customers. :)

Both Hannah and Julia have provided an excellent and professional service, making the process of the sale more manageable and keeping us up to date with any issues that arose to keep the process moving. Being able to communicate by text has also made the communication flow much better for any quick updates or quick questions.
Thank you Ivonne for your five star review. 😊 All the best with your new move. …

Having met with both Julia and Hannah while house hunting I was very impressed by their detailed knowledge of the houses we were shown, and the surrounding area. A very professional business with their fingers on the pulse of the housing market. Very handy that you can contact them by text message, with a speedy response.
Thank you for your lovely review

Greenhills are a lovely agency run by two very professional ladies. Very thorough with due diligence, work hard to make the whole process run as smoothly as possible and are a good intermediary between seller and buyer. I would definitively work with them again.
