Really knowledgeable and helpful broker

Adam has a real breadth of experience and knowledge about property finance. He was able to introduce new concepts to me (I am a serial investor who has a portfolio of HMOs for the past 16 years). So that was very refreshing. He also really understands the numbers and with his experience he was able to use illustrations and examples from past projects to help me understand the options available to me. I appreciated his helpful approach, and his speedy responses - thank you Adam!

Al C

I have used KWM (and more specifically, Adam Stiles) for my last three mortgages. Adam has been really helpful in both an advisory and organisational sense. He works effectively, ensuring all bases are covered from the beginning, and avoiding any last minute / urgent requests other brokers/lenders tend to make. I've recommended him successfully to friends, who have equally pleased. Having worked with Adam through the mortgage capacity i will definitely seek out further wealth management advise in future. Trustworthy, reliable and friendly. I recommend Adam every time.

Tricky requirement, easily arranged!

I have had the pleasure of speaking to Adam Stiles at Keystone on a number occasions concerning my financial needs. Each and every time I have been impressed with the clarity and speed of response but most of all his ability to find products that exceeded my expectations especially when given complicated parameters. I have recommended his service often and will continue to do so without hesitation.

Adam Stiles - The Best in the Business

I have used Adam Stiles on numerous occasions and couldn't recommend his services more highly. Very professional, yet proactive. With excellent communication, providing help and assurance every step of the way. A great service by someone who genuinely cares.

By Rachel Wood on 19/07/2019

Excellent service

We have just had a mortgage and associated protections arranged by Adam Stiles at Keystone. Throughout the process, Adam has been excellent at keeping us informed in a professional yet friendly way especially when the process seemed to stutter. I would have no hesitation in recommending Adam and his colleagues.

By Paul Evans on 19/07/2019

Outstanding Service and Advice

I have recently arranged a mortgage through Keystone with Adam Stiles. I have used a broker before successfully but I was not expecting the process to be managed as smoothly, effectively and quickly as it was. Adam's experience is outstanding and he was able to navigate through a myriad of options with clarity and sound, thoughtful advice; and even more impressively facilitate a mortgage offer in a very short space of time by taking complete control of the process. He handled the extraordinary volume of paperwork involved easily and in double quick time, and progressed to formal offer with ease. I would strongly recommend a conversation with Adam if you are considering mortgage options and would be confident there isn't anyone else in the market who will deliver as smoothly or effectively on what you need.

By Liam Farncombe on 17/07/2019

Top company

I have been using the services of Keystone through Adam Stiles for a number of years now. Adam has been looking after my mortgage and personal insurance policies. He always manages to find the best deals on the market that meets all of my needs. Adam is very honest and reliable person, he always puts his clients first and is pleasure to deal with.

Adam Stiles - Keystone

I have had the pleasure to work with Adam across multiple projects and have always found that he digs out the most competitive terms from a debt and JV equity perspective. He understands our requirements and tailors the proposals to us accurately every time. He is also fast and that I only imagine is down to his established relationships in the market. Speed is crucial in our business. I would highly recommend Adam going forward.

By Ben Nicholas on 09/07/2019


I have used Adam for around 4 years now and I honestly would never trust anyone else. Being self employed and trying to get a mortgage comes with so many issues, however Adam helped me get two mortgages with extremely low rates. During the stressful admin period he assured me we would have nothing to worry about and he’d be able to make it work somehow and he did just that. Have also used him for my home insurance, landlords insurance and life insurance. Not only massively professional and trusted but also took the time to send me a congratulations card on my engagement. All round incredible service.

By Holly Hagan on 09/07/2019
