I recently used Alexander Southwell Mortgages to arrange a mortgage for my flat, and the service was absolutely brilliant from start to finish. Cheryl, my broker, was incredibly knowledgeable, efficient, and supportive throughout the whole process. She made everything so straightforward and stress-free - I had a mortgage offer accepted within around a week, which exceeded my expectations. Communication was always clear and timely, and I felt fully informed and in good hands the entire time. I wouldn’t hesitate to recommend Cheryl and the team at Alexander Southwell to anyone looking for a reliable, professional mortgage broker.

Highly recommend using Alexander Southwell Mortgage Services for a mortgage. It was excellent to have Andrew help us with finding the best rate mortgage to suit our needs as first time home buyers. We were walked through the process and all the work was on there end. Will use again when it is time to get a new mortgage. Thank you!!

Jamie and the team at AS Mortgages have been superb at helping sort out a new mortgage for a house move. From searching for the best product, to finding the best lender, they have been amazing.
This isn’t the fist time we have used the services at AS mortgages. Previously have helped us with two other mortgages on previous properties and securing a new fixed rate. Every time the service is quick, easy and painless. We have recommended AS Mortgages to family, friends and colleagues - everyone who has used them has had the same great experience as us. Can’t recommend highly enough.

Excellent service from day one, Jamie is very attentive, understands the exact needs of the client, communicates well and keeps you in a loop of any mortgage rate changes that might benefit you. I had several different mortgage advisers in the past and this is the best experience so far! Highly recommended!

Previously, we had been given unaffordably optimistic deals, or bluntly told "No" without a reason, by several mortgage advisors.
Fortunately we were put into contact with Alexander Southwell, where Jamie was able to clearly explain the process of getting a mortgage, all the steps we would have to go through, and then secured for us an affordable mortgage. He kept in regular contact about hwo the deal was progressing, and was also flexible in making and taking calls from us. Thank you, Jamie.

We had a great experience with Andrew. I'm very grateful for the quick and efficient process. Andrew has given us all the information & advice we needed and helped us find the right lender for our circumstances. We will definitely be recommending Alexander Southwell Mortgage Services to our friends. We look forward to using the same service for later when we remortgage! Many thanks.

Excellent service throughout the process of mortgage application from Jamie, we use Southwell Mortgage over 5 year now on more than one property. also pleased recommend him to our friends. He is very hands-on and very good at explaining the process and making sure he follows correct procedures to work within ethical guidelines, yet makes customers happy by educating whats right for us when making a mortgage by reassuring them the whole time. He is very friendly and proficient in checking and requesting the right documents, also more than happy to answer any questions that I had and was quick to respond to any enquiries that I sent to him. Cannot recommend enough this highly professional, positive and motivated person!

Brilliant experience from both Jamie and Latoya- can't thank them enough. As a first-time buyer, the home-buying process has been quite confusing and filled with unnecessary jargon, with the exception of this service. Both Jamie and Latoya have been really informative, reliable and removed any element of stress from securing a mortgage. Thank you so much, will highly recommend.

I was recommended Jamie at Alexander Southwell by a Hampshire based housing developer. Both myself and my partner are self employed so finding a mortgage to suit has always been difficult in the past. Jamie however managed to get us a mortgage offer within a week with no issues at all! Amazing service and highly recommend.

Me and my girlfriend recently used Jamie as our mortgage advisor for the purchase of our first house and he was fantastic. As first time buyers we felt a bit out of our depth but Jamie was always on hand to answer any questions and help us anyway he could. This really helped us to understand the whole process and get to the point where we have now had an offer and our mortgage accepted.
I would recommend Alexander Southwell Mortgage Services to anyone, nothing but good things to say about them. Once again thank you Jamie, couldn't of done it without you!
