Services
Alexander Southwell Mortgage Services supports first-time buyers with expert, no-cost mortgage guidance. We assess your financial situation, calculate potential borrowing amounts, and clarify repayment obligations. By providing access to exclusive mortgage deals, we simplify the process of securing your first property, allowing you to make informed decisions while minimising financial stress and understanding every stage of your mortgage journey. 
Our approach to moving home mortgages centres on offering clarity and personalised guidance. Clients receive support in assessing borrowing limits, understanding deposits, and selecting appropriate mortgage types. By anticipating costs and addressing insurance needs, we ensure a seamless process from application to completion, helping homeowners transition to their new property with confidence and peace of mind. 
Self-Employed MortgagesSecuring a mortgage when you’re self-employed can feel more challenging, but with the right guidance it doesn’t have to be. We specialise in helping business owners, freelancers, and contractors find competitive mortgage solutions that reflect their unique circumstances.
Lenders often require evidence of income such as tax returns, accounts, or SA302s. We’ll work with you to present your finances clearly, explain what different lenders look for, and identify the options most likely to suit your situation.
Whether you’re newly self-employed or have years of trading history, we have access to lenders who understand flexible incomes and non-traditional employment. Our goal is to make the mortgage process straightforward, giving you confidence that your hard work translates into the right home.
Key Worker MortgagesWe recognise the vital role key workers play in our communities, and we’re committed to supporting them in achieving their property goals. Whether you’re in healthcare, education, emergency services, or another public service role, we can help you access competitive mortgage deals tailored to your needs.
Some lenders offer special considerations for key workers, including lower deposit requirements, enhanced affordability criteria, or exclusive schemes. We’ll guide you through these options, ensuring you make the most of the support available while comparing the wider market to find the right deal.
Our advisers provide clear, friendly advice and handle the application process from start to finish, giving you more time to focus on the work that matters most.
At Alexander Southwell, we provide expert mortgage advice across the UK without charging any broker fees. Our independent team searches the entire mortgage market to locate the most suitable products for your circumstances. We manage the application process on your behalf, ensuring clarity and efficiency from initial enquiry to completion. Your financial needs remain our central focus throughout. 
Mortgage Capacity ReportA Mortgage Capacity Report provides a clear, independent assessment of how much you may be able to borrow for a mortgage, based on your income, financial commitments, and current lending criteria.
Often requested in divorce or separation proceedings, this report helps solicitors and the courts understand your realistic borrowing potential. It outlines the mortgage products available to you, affordability calculations, and any factors that may impact your ability to secure lending.
Our reports are prepared by qualified mortgage professionals, are FCA-compliant, and are tailored to your personal circumstances. They provide an impartial, evidence-based view that can support negotiations, financial settlements, or legal requirements.
With our expertise, you’ll have a clear picture of your mortgage options — giving you confidence in planning your next steps.
Alexander Southwell Mortgage Services partners with you to make the most of CheckMyFile’s extensive reporting. By drawing information from multiple credit reference agencies, it reveals the full picture of your credit history. We guide you through interpreting the findings, addressing any concerns, and improving your creditworthiness, ensuring you are well-prepared for your mortgage application.

God bless Latoya. She came through for my wife and I when we were at our lowest as first time buyers. Here's how:
My wife got a mortgage deal with a certain renowned mortgage company. I thought to do some due diligence and that is how I stumbled across Latoya of Alexander Southwell Mortgage Services on Google. Her speed and accuracy is breathtaking. Her offer was comparatively similar to what wifey was offered so I decided to go with wifey's mortgage broker and notified Latoya. Thing is, Latoya expressed no feeling of disappointment, instead she wished us well adding her doors would remain open should we change our mind or need further advice. Little did I know I just shut the door on who would later become our saviour because fast track to almost 8 weeks later, wifey's mortgage company let us down as our mortgage application was cancelled by the lender. Worse still, wifey's brokers did not know of this cancellation outcome until I chased things up a week after the cancellation occurred!
As soon as this devastating news was confirmed, I sent Latoya an email out of hours to which she promptly responded. Next day, she submitted another mortgage application on our behalf with an even better rate! This was approved within one week! Now you understand why I started out by saying "God bless Latoya".
And God bless Alexander Southwell Mortgage Services too.

We were introduced to Jamie by a close friend, and we couldn’t be more grateful. He is truly the best and most professional broker we’ve worked with. Jamie was extremely patient and guided us through every step of the application process with clarity and care. He took the time to listen to our thoughts and address all our questions in detail.
His team, especially Tylor, was also outstanding—always responding promptly, often within the same day. We deeply appreciate all the support and are very thankful for helping us achieve a successful outcome.

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.

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!

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.

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.

We are quite happy that we followed our mutual friend's recommendation and met Jamie. Many mortgage advisors failed to secure me a mortgage for the property I was attempting to purchase, but Jamie was able to assist me in obtaining an offer within a week.
All of our inquiries were promptly and reassuringly addressed. Once again, BIG thanks to Jamie, I will be referring Alexander Southwell Mortgage Services to everyone who needs a mortgage.

I was recommended to Andrew by a friend , he is excellent at what he does and explains everything, advice about mortgage rates that you're not sure what to do with, or if they’re right for you and your circumstances all cleared up. His expert comparison to save on any new remortgage deal and made me 100% confident in my options.
My mortgage completion was last Friday . I have already recommended him to a work colleague as his mortgage runs out next year . Many thanks Andrew

Jamie Alexander managed to get me a Mortgage offer within 5 days after previously being let down by a different Mortgage Broker with an application that dragged on and on and after 8 weeks was rejected.
My house move is now happening after almost falling through with the other broker.
Jamie is very knowledgeable and matched me with the right lender. I am self employed but have still managed to secure a Mortgage with a high street lender thanks to Jamie's professionalism.
Highly recommend !
