I have worked with Mason Thomas Law since March 2020 and been impressed. So much so that I am now using them for conveyancing on property purchases which we are then developing. Jo does exactly what she says she will do. They always get everything over the line on time for all deals we’ve been involved with and I couldn’t ask more than that.
Robert Askew, Managing Director of Ralane Properties
Thank you for your professional service and yet also your kindness during the purchase process. You were so thorough and we really felt you had our very best interests at heart. We really appreciate everything and will not hesitate to recommend you, you are a total credit to Mason Thomas Law.

What clients say about us

"Working with Mason Thomas Law has been great. The team handled our lease renewal and it was as straight forward as they said it was going to be - it's been a quick and easy process."
Sue Crossland - Uncle Sam's

What clients say about us

"Huge thanks to the team at Mason Thomas Law. Twice previously we've bought and sold properties and we've not had the greatest experience with solicitors. The experience with Jo and the team at Mason Thomas Law was so different! Everything was slick and super speedy. They were great at explaining things in an easy to understand way, so we always knew what was happening and why. We would have no hesitation in recommending them to others. 5 stars and thank you so much."
Mrs L - Derbyshire

What clients say about us

"I obviously have a certain amount of knowledge and experience when it comes to the practical side of developing properties but having Jo to explain the legal procedures and really break it all down into layman's terms for us has been so helpful. She has been fantastic. I can pick up the phone to her any time – that's crucial when we have to turn deals around and make decisions quickly."
Matt Lipscombe - High Altitude Properties

What clients say about us

"Thank you for your help in this matter, you and your team were very professional and made the process very easy for us to understand. I wouldn't hesitate to recommend Mason Thomas Law to anyone else I know who is going through the same situation."
Mr J, Derbyshire

What clients say about us

"When you choose to do a bridging loan it's principally because you need the money quickly. If you choose the wrong solicitor, the deal can fall over and you can incur costs. That's why I always recommend the Mason Thomas Law team to my clients. I know they will ensure the deal gets done. The team make it a simple and quick process. They are always on hand to answer any questions and update me to ensure the process keeps moving. That is so important to me and my clients."
James Furniss - SMH Commercial

What clients say about us

"Mason Thomas Law was recommended to me by someone I trust, and I wasn't disappointed. Having Cathy on hand to explain the details in layman's terms was a real bonus and time saver. It was great to be able to pick up the phone and speak directly to her at any point throughout the negotiations."
Alex Moore - LYKKE and HYGGE

What clients say about us

"Absolute brilliant, you know you’re in safe hands and Cathy's been a god send to us. We can’t thank her enough."
Mark Mcgrail - SME Ltd

What clients say about us

"Buying a house has many elements that can be testing and often frustrating, but Mason Thomas Law managed the conveyancing process incredibly smoothly considering the complexities of our particular demands."
Mr and Mrs Gibb - Sheffield

What clients say about us

"Having used Cathy in the past for the purchase and lease of business premises, the team at Mason Thomas Law acted on my behalf for my recent house move. Having moved numerous times in the past, I can honestly say that this was my least stressful move to date. A massive thank you to Cathy and Jo for a smooth and very professional service."
