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.

So this was myself and my partners first time buying and honestly we were totally clueless on the process! A mutual friend/client of Jamie & Latoya recommended them to us and I’m so incredibly glad he did.

From the start, Jamie quickly put us in touch with Latoya and we got things underway instantly. Throughout the whole process, communication was utterly seamless and there was no such thing as a silly question (trust me, I asked a few!). Latoya was transparent about every step, advising us down the best possible avenue - ensuring we got the best outcome for us. Keeping us up to date about each part of the application process, there was absolutely no need to chase - as soon as she had anything for us - we were straight in the loop.

Honestly, she made what was quite a daunting idea to us - so reassuring and easy.

Thank you so much to Latoya and Jamie for your incredible service and support! We’ll be singing your praises and sending anybody we can, your way 😊

All the best to you both,

Joe & Naomi

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.

I have nothing but positive things to say about this company. I felt looked after from day one and the communication has always been great. I personally dealt with Latoya who is very knowledgeable and handles your affairs with confidence. I would 100 percent recommend.

We couldn't have asked for a better mortgage broker!! We're so glad they were recommended to us and we went ahead.
Andrew helped us with a total of 3 sales over the course of a year, 2 of which had unfortunately fallen through on the seller end. Andrew was always at the end of emails/phone to help us along each step and with any extra queries. We're so grateful for the expertise and great communication we recieved, thank you so much!!

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!

Both Jamie and David were very helpful, knowledgeable and friendly. They explained our options, then found us a mortgage with a great rate very quickly. They then supported us through the process including updating us when rates on our deal improved. And it didn't cost us anything, would highly recommend.

We had the pleasure of Jamie being our mortgage adviser, being first time buyers we didn’t know the process very well but he was absolutely brilliant from the word go, could’ve have done more to help and would highly recommend his to anyone!

After being turned down by other brokers, Andrew stepped in and managed to secure me a mortgage quickly and without any hassle. His expertise and efficiency made the whole process stress-free, and I really appreciated how straightforward he made everything. If you're looking for someone who can deliver results when others can’t, Andrew is definitely the person to go to.

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!

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!
