One of the best things I experienced was the personal touch. It can be daunting dealing with solicitors and I never felt like a hindrance. Gary was always available on the phone and email for me and always responded very quickly. I know of an elderly person dealing with Gary who really appreciated being able to meet face to face in a place where she felt comfortable. I think both types of meetings are great as clients have various needs.


Friendly, easy to talk to, professional support from start to finish. The service was exceptional, communication was timely and never overbearing. Everything was explained clearly along with expected timelines for completion. The team went above and beyond to sort out any issues that may have arisen during the process. Overall, very satisfied with the service.


What we found best was the professionalism of the service overall, the confidentiality, empathy and understanding. Communication was always clear in both e-mail and in person. Response times to e-mails, and meetings, was very good. I believe your fees are very competitive, and good value for your service.
