"Simply superb. Our new "go to" mediator." (Partner, City Law Firm. April 2026)

"Andrew was simply superb. He unlocked a mediation many others would not have been able." (Partner, City Law Firm. April 2026)

"Andrew was excellent. This was not the first mediation that I have attended with Andrew mediating and I was keen to recommend his assistance on this case. He remains attentive throughout, grasps the issues straight away, relates to the parties and does all that he can to help the parties reach a conclusion." (Senior Associate - City Law firm. September 2022)

"Andrew showed great compassion whilst also being firm. He was so well briefed the client was so impressed. This is now the fourth mediation in a row that Andrew has successful managed to get the parties to a resolution for me and my clients. I cant praise him enough. His attention to detail and approach in seeking to bridge voids between the parties position is second to none." (Director - City Law firm. October 2021)

I was initially sceptical about mediating via video-link. We agreed to it when mediating in person was no longer an option. However, I was impressed by just how well the virtual mediation was expertly coordinated by Andrew in such a way that the dynamics of a mediation, which are so important to settlement, easily translated on to the “virtual” platform. (Associate - City Law firm. March 2020)

"Yesterday restored my faith in mediation and mediators. It went really well and I thought you did a great job. Whisper it, but don't you think that having the client participating from their own home was actually better than a traditional mediation. My client this morning told me she felt completely relaxed all day and just focused hard when the Skype calls occurred." (Partner - March 2020)

"For all of the parties it was their first virtual mediation which was expertly navigated by Andrew. I would not hesitate to recommend Andrew for any mediation. (Partner - March 2020 )

"I have been mediating for over 20 years and I cannot think of a mediator who puts in more effort than Andrew. His ability to cajole those afflicted with outright lunacy is also very much appreciated."

"A refreshingly different & much more constructive approach from Andrew. I think I could go as far as saying that he restored my client's faith in mediation after some less positive mediations." (Solicitor, City Law Firm)

"Andrew was an excellent mediator, probably one of the best that I have seen in 26 years of being in practice. The dispute has really been ongoing for nearly 20 years between sides of the family and it was a really excellent result that Andrew achieved for the parties. Andrew was very understanding of the clients' position and dealt with their issues and concerns in a very empathic but firm manner. I would certainly have no hesitation in recommending Andrew again as a mediator." (Solicitor, City Law Firm)

"Andrew is an excellent Mediator.  His mediator skills made a decisive difference to the outcome of the mediation.  He gave us the confidence to know that that he was trying hard to explain our position to the other side while conveying to us (even if not explicitly) what might be the other side’s red lines." (Party to Mediation, CEO)

"Andrew is a highly skilled mediator. He quickly identified a range within which the parties might settle and worked towards that and also stepped in when required during the negotiation of the more difficult finer details to ensure the deal for over the line on the day (or night, as the case was!)." (Partner at City Law Firm)

"Andrew showed tremendous experience, psychological skills, business orientation and leadership in guiding the parties to a successful conclusion of the mediation with a Settlement Agreement.  The mediation conducted by Andrew Miller KC has been a unique and valuable learning experience for me personally, but I believe also for all others involved in the mediation." (Party to Mediation, CEO)

"I believe that Andrew's mediation skills and abilities and his outstanding commitment and professionalism throughout the mediation were key factors in the successful resolution of the dispute between the parties. I was very impressed with his pragmatic and business-minded approach and his direct and straightforward style of play. We would certainly recommend Andrew as a mediator to others and we would seek to appoint him if we had another mediation dispute." (Partner at City Law Firm)

"I have dealt with many mediations in a range of disputes in recent years and found Andrew's approach the best to date . An excellent mediator who was perfectly suited to our case."

“Andrew definitely made a difference by helping the parties focus on their real needs to reach resolution.  Andrew is very skilled and made the process virtually painless. This is how mediation is supposed to work.” (In house Legal Advisor – Global Manufacturer of Wind Turbines)

“I was not sure we were going to get to a resolution - but we did, and I suspect that was a result of the process adopted by Andrew.   There was a significant difference between the parties in respect to quantum and liability and Andrew skilfully brought the parties to resolution.” (Loss Adjuster, Insurance )

“We were impressed by Andrew’s conduct of the mediation.  He was sensitive to commercial issues and had a very strong level of legal expertise. (Senior Partner – Large commercial firm)

I would not hesitate to recommend Andrew as a mediator.  He was able to cut through the issues quickly and this led to the parties making concessions early in the day.  Andrew's pragmatic approach meant that the parties were sensible and were able to focus on the most relevant aspects of the case, which in turn meant that a settlement was reached. (Senior Partner– London City Firm)
